Pre-condition survey report

Introduction

At the request of the client, Lambeth Living, ESW Operations Manager Myles Chambers surveyed the existing roof areas on Blocks E & G and the communal covered walkway for new external works applications. Following core sample tests, results were submitted to Kingspan for Insulation specification to BBA Certification. The flat roof finish totals around 1,500m2 over 7 blocks. This includes tank housing roofs, which feature a raised check kerb to perimeter. The covered walkway roof starts between blocks A/H & G and continues through the estate finishing between blocks C&F. The existing roof waterproofing system for all roof areas, including covered walkway, comprises mineral felt in multiple layers installed on wood wool slab, with some sections coated in solar reflective paint. No insulation appears to be present in the existing roof build-up. Terminations are formed of block upstands with mineral felt dressed into edge trims. On the covered walkway, terminations are formed by raised upstands at outside edge and felt flashing on inside edge.

InspectionOverview

Patching to the main roof is evident, where pooling water has gathered to contribute to the deterioration of the roof covering.

Outlets and channels are ineffective in draining water from the roof, allowing ponding to take place. This has contributed to degradation of the felt roof coating.

Roof coverings, in particular at Blocks E and G, appear to be degrading. The mineral felt and solar reflective coating are no longer serviceable and channels to roof outlets are preventing water flow, resulting in standing water on the roofs.

Tank housing: The mineral felt roof covering has degraded sufficiently to warrant a new roof finish, although a thermal upgrade has not been specified at this time.

3

Covered walkway: The mineral felt roof covering is installed over wood wool slab the raised upstand terminations and felt flashing on inside edge. The roof covering has degraded sufficiently to warrant a new roof finish, although a thermal upgrade has not been specified at this time.

Balconies to first floor, 4no per block. Mastic asphalt where visible was found to have migrated in areas and minor cracks were visible. Upstands in need of repairs and falls are untested. Where mastic is not visible promenade tiles were observed, although not all balconies were available for survey.Level surveys would be required to ascertain the functionality of the drainage. Outlets observed were blocked and in need of cleaning and potential overhauling/replacement. It is recommended that any covering tiles to these areas be tested for ACMs.

Core Samples & Observations Core samples were taken from the main roof area of Block E and Block G to confirm the current roof system build up and to assess the condition. It appears that all remaining blocks are in a similar condition and with similar roof build-up. The following core test sample results have informed recommendations for a proposed new roof build-up.

NB No damp readings are available, since insulation was not thought to be present.

Based on the initial findings the roof coverings are beyond their serviceable life and will degrade further, causing failures. Our recommendations would be to install a warm roof built-up system as follows:

Flat Roof Area (Main Roof)

• Pressure wash existing roof to remove all vegetation and surface contaminants.• Kingspan Thermaroof TR27 (120mm) rigid PIR board chemically fixed to the substrate to achieve requiredU-values• Remove existing roof lights, extend kerbs using timber fillets to enable a minimum 150mm upstand. Installnew rooflights, 1no non-opening unit above communal stairwell. 1no unit with mechanical vent above bathroom(spec sheets included)• Fix IKO Profatherm 2.5mm carrier sheet

• Spray apply Prokol Seamless 260 FR CE certified fast cure polyurea at 2.5mm DFT in black or grey

Flat Roof Area (Tank Housing Roof)

• Pressure wash existing roof to remove all vegetation and surface contaminates.• Fix IKO Profatherm 2.5mm carrier sheet

• Spray apply Prokol Seamless260 FR CE certified fast cure polyurea at 2.5mm DFT in black or grey

Flat Roof Area(Covered Walkway Roof)

• Pressure wash existing roof to remove all vegetation and surface contaminates.• Fix IKO Profatherm 2.5mm carrier sheet

• Spray apply Prokol Seamless 260 FR CE certified fast cure polyurea at 2.5mm DFT in black or grey

Parapet Wall, Lower Level Roof Edge and Abutments

• Pressure wash existing felt coverings• Fix New GRP edge trim; 40mm at parapet level, 150mm at lower level• Abutment upstand to be minimum 150mm above finished roof level• Fix IKO Profabase PES detailing sheet adhered to both carrier sheet and brickwork• Spray apply Prokol Seamless 260 FR CE certified fast cure polyurea at 2.5mm DFT in black or grey Balconies

• Remove existing promenade tiles where present• Clean and remove debris• All outlets assumed to be functioning correctly; existing falls also assumed to be functioning correctly• Diamond grind/wire mop to create mechanical key• Repair/install new upstands• Roller apply Prokol Primer UNI• Roller apply Prokol Rocathaan PA M300• Roller apply Prokol Floorcoating AS/Prokol Topcoat 35 AS• Install new promenade tiles using PU adhesiveConclusionThe current roof covering is reaching the end of its serviceable lifespan. The proposed thermal roof installationwould completely encapsulate the roof with no seams or weak spots. Based on this application and installation ofinsulation at the correct thickness, the roof would be thermally efficient and in line with current regulations. Thisbuild-up would not require the removal of the existing roof and subsequently there would be little to no risk ofwater ingress during installation. With reference to balconies, the proposed system will provide a waterproofmembrane to seamlessly protect the existing structure. Level surveys to be undertaken to ascertain functionality ofdrainage. Levelling screed to be used if required.

Prokol Polymers UK is pleased to submit the warm roof and balcony coating specification for the proposed overlay application works to the project/projects noted in this document. Prokol Polymers warranty would cover the following waterproofing specification for a period of no less than 30 years. Our products are fully independently CE certified and we are an ISO 9001 -14001 registered company. Our roof waterproof applications are also fully certified to Fire classification as overlay to bitumen according EN 13501-5 B Roof (t2) – TUV Fire classification as overlay to polyurethane spray foam according EN 13501-5 B Roof (t2) – TUV · Fire classification as overlay to non-flammable materials like steel, tiles etc.according EN 13501-5 B Roof (t2) – TUV

Fit For Purpose Products: - Prokol Polymers CE Certified systems are fully hydrophobic with up to 1400% elongation for thermal expansion & contraction. Cure time is 20 seconds with instant waterproofing effect. Prokol Pure Polyurea will not suffer from hydrolysis degradation and is engineered to retain sitting water. It is a seamless, monolithic and high performance coating that contains no solvents, zero VOCs and is fully UV Stable. Plant growth cannot cause damage through secretion of acid during root development and the systems are manufactured with full life cycle analysis and are designed for zero maintenance. Overlay applications can result in positive environmental actions; waste associated with removal of existing products minimal and economical benefits can be significant. Another key benefit of overlay applications is possible reduction in thermal value calculations as part of a composite build up, which may assist with EPC Certification.

Warm roof specification

Deck: - The existing deck is believed to be as described above. If our findings are found not to be the correct please contact us, as the specification may need to be amended accordingly. The existing bituminous waterproof layer is to remain in place.

Preparation: - Remove any existing debris and dispose in accordance with our waste management system. The client should be duly informed. The specification makes no allowance for changes to the existing roof drainage and water carrier system. All existing roof protrusions will be abraded to receive final seamless waterproof membrane termination at minimum height above final application of 75mm. All proof level protrusions should be inspected for asbestos content and dealt with accordingly.

Vapour control layer: - For refurbishment projects, involving the addition of insulation to existing insulated flat roofs, or roofs constructed of insulated steel faced composite panels, it is imperative that a U–value calculation and condensation risk analysis is carried out for every project, in order to ensure that the correct thickness of insulation is installed to achieve the required thermal performance, whilst avoiding interstitial condensation.

In refurbishment projects, where Kingspan Thermaroof ® TR27 LPC/FM is to be installed over an existing bituminous waterproofing membrane, the membrane can be used as a vapour control layer, as long as it is in a good water tight condition. Where this is not the case, a separate vapour control layer should be installed. The type of separate vapour control layer required will be dependent upon the chosen method of fixing the insulation boards. For mechanically fixed applications, a minimum vapour control layer should consist of a 1000 gauge (250 micron) polythene sheet, with all joints lapped and then sealed with double-sided self adhesive tape.

For applications where the insulation boards are to be bonded to the vapour control layer, a minimum vapour control layer should consist of a coated roofing felt complying with Type 3B to BS 747: 2000 (Reinforced bitumen sheets for Roofing. Specification), or S1P1 to BS 8747: 2007 (Reinforced bitumen membranes (RBMs) for roofing. Guide to selection and specification), or any appropriate metal–cored vapour control layer. Where the separate vapour control layer is to be bonded, allowance should be made for adequate bonding of the vapour control layer to the substrate, so as to provide a suitable surface upon which to lay the insulation boards and sufficient resistance to wind up–lift (see ‘Wind Loading’).


11

Insulation:- Apply the Kingspan TR 27 LPC/FM PIR 130mm (0.18W/m2 K) insulation boards using Kingspan recommended polyurethane insulation adhesive at the specified centres and bead size (refer to manufacturer for clarification). Please note that it is the responsibility of the roofing contractor to ensure that the insulation thickness meets current standards. If standards are met or surpassed then no further action is required. If they are to fall short then the roofing contractor must receive written instruction from the building owner that this is acceptable to said building owner. (Kingspan data sheet attached) install treated timber hard edges to all external perimeters, gutter edges etc., securely fixed to the roof deck. Thickness of the hard edge should be reduced sufficiently to avoid creating water checks and allow lapping of the waterproofing layers. All board packs are clearly marked with date/time of manufacture, board type and thickness for ease of identification. Ideally, boards should be stored inside a building or undercover. If, however outside storage cannot be avoided, boards should be stored flat and off the ground. Full protection in the form of tarpaulins or heavy gauge waterproof sheets must be provided at all times whilst on site. Boards that have been allowed to get wet must not be used.

Linear Thermal Bridging: - Reasonable provision must be made to limit the effects of cold bridging. The design should ensure that roof–light or ventilator kerbs etc. are always insulated with the same thickness of Kingspan Thermaroof ® TR27LPC/FM as the general roof area. A 25mm thick Kingspan Thermaroof ® TR27LPC/FM up stand should be used around the perimeter of the roof on the internal façade of parapets. A minimum distance of 300 mm should be maintained between the top of the insulation up stand and the bottom of the horizontal roof insulation. Wall insulation should also be carried up into parapets as high as the flat roof insulation up stand. Please contact the Kingspan Insulation Technical Service Department.

Carrier Layer: - IKO Profatherm 2.5 mm self adhesive carrier layer with joint overlaps of 10cm, no hot application is required, adhesion is made by removing the peel-off backing and unrolling the self adhesive surface and bonding directly to the insulation board. Temperatures greater than10°C use a weighted roller to roll the carrier membrane to ensure maximum adhesion is achieved. Where temperatures drop below 10°C, a chemical activator is to be applied directly to the lap joint areas to ensure a tight competent bond. All details should be installed as separate items and must be bonded to the field area a minimum of 20 -30cm above the finished level of the insulation. All side laps are to be fully sealed, as the layer at this stage will leave the roof fully waterproofed ready for the final seamless waterproof membrane.



12


Roof Drainage Detail: - Installation of new T-Pipe Drainage System T-Pipe sump flange outlets are manufactured to the same technical specification as the flat flange outlet the sump increases the rate of rainwater flow into the drain. The long downpipe is ideal for installation in deep roof slabs. A leaf guard/gravel grate completes the system and incorporates a ribbed collar, which sits in the sump to retain the guard. (See data sheet attached) The Prokol membrane system will encapsulate the outlet detail as part of the continuous seamless system.(membrane termination example drawing attached)

Comments during application

The amine (A) component should be mixed carefully before usage until a complete homogenous mass is obtained.

The mixing time depends on the size of packaging. A 200 L drum used for the first time or being used after a long period of time should be mixed intensively for 45 minutes. Following this, short and thorough mechanical mixing is sufficient.

Non-homogenous mixed products lead to deviating features in the end-result. Subsequently, after a couple of weeks or months, this may also lead to amine or isocyanates remnants bleeding into the finish.

Do not inhale spray mist. Ensure respiratory equipment designed for the conditions is worn while spraying.

The ambient and surface temperature must not be lower than +5ºC, whereby the temperature of the base to be treated must be 3º above dew point. Condensation on the base reduces adhesion. Consult the dew point table.

The application of two component products may only be undertaken with a relative atmospheric humidity of less than 85 %.

Surface and conditions

The surface needs to have a closed structure without pores. The surface must be dry, clean and free of grease. The surface must also be suitable for the current purpose. Treat the surface in the correct manner and use an appropriate primer our webbing, if needed. In that case, read the technical product sheet of the product in question.

Bitumen surfaces

The surface needs to be clean and free of grease. Loose parts need to be removed. A primer may be necessary in some cases. Consult the most recent primer overview.

Always use a suitable surface preparation. A primer will be necessary. Consult the most recent primer overview.

Moisture content of surface: < 4% (parts by weight).

Metal

Steel must be blasted to provide an anchor profile of 75 to 100 micron according to DIN EN ISO 12 944, Part 4. Use filters to avoid clogging of the drains.

Note:

Various types of substrates are available, some of which have individual pre-treatment requirements. If in doubt, contact your supplier for more information.

Important

Due to its aromatic composition, Rocathaan Hotspray PA 260-FR, will tend to yellow or darken in colour and become flat after exposure to UV light. Rocathaan Hotspray PA 260-FR may be over coated. If a top coating is to be applied as a finishing layer, it must be suitable for the purpose and elasticity of the soft polyurea.

Projects and uses can vary greatly. Always contact your supplier if in doubt about a certain use, choice of material or surface treatment.

PROFATHERM BASE SA 01570707

24/06/2015 TF Profatherm Base SA 01570707-en.doc - lva -1/1

Roofing membrane consisting of a impregnated polyester rein‐forcement, coated on both sides with flexible coating bitumen and bottom side provided with a build‐in vapour diffusion layer based on diamond‐shaped profiled self‐adhesive SBS modified bitumen.

‐ The polyester carrier has a high mechanical strength and is accessible during operation.

‐ The build‐in vapour diffusion layer is based on diamond‐shaped profiled plots consisting of self‐adhesive SBS modified bitumen. The adhesive surface underneath is about 40 %, so that the ideal relation between wind resistance and vapour pressure exposure is achieved. The optimal vapour pressure diffusion is achieved by the broad, diagonal canal structure of the non‐faced reinforce‐ment.

‐ The bottom side is covered with diamonds of self‐adhesive SBS modified bitumen, which guarantees an immediate and high bonding to the supporting substrate.

‐ The topside is finished with quarts mineral and a removable silicon foil of 8 cm at the side lap area. This guarantees fast and secures water tightness.

‐ The bottom side is finished with a removable silicon foil.

APPLICATION

Used as self‐adhesive vapour pressure diffusing under layer in a multi‐layer roofing system. Can be placed on substrates with enough delaminating resistance such as concrete, existing bituminous membranes, stable wooden supports. First coat the surface with IKOpro Self Adhesive Primer.

Secondly, as a first layer on naked EPS or glass fibre faced or ALU faced PUR, PIR (e.g. IKO enertherm MG/ALU): do not prime‐on be‐forehand! The special composition of PROFATHERM BASE SA allows the insulation not to get damaged by transmission of heath during torching of the top layer.

Temperature in application 10° C. In case of application during colder periods the material should be stored at least 12 hours before application in an ambient tempera‐ture of ≥ 10° C.

COMPOSITION

Carrier polyester, 170 g/m² Bitumen coating mass:

DIMENSIONS

Thickness: 2,5 mm Length: 10 m Width: 1 m Weight: 35 kg

APPLICATION

PROFATHERM BASE SA is applied as base layer in multi layer roofing systems. The substrate should be smooth, dry, clean, fat‐ and dust free. All substrates, with exception of thermal insulation, needs to be coated with bitumen primer IKOpro SA Bitumen Primer. The first membrane is unrolled and lined out and rolled up again till approximately half the length of the strip. The removable silicon foil should be cut in cross direction and pulled up in one time while un‐rolling the membrane. This way, the self‐adhesive underside will get in direct contact with the substrate and stick immediately. The same procedure should be repeated for the other end of the roll. The next membrane PROFATHERM BASE SA is applied in the same way with a side lap of 8 cm and an end lap of at least 25 cm. Pressure shall be exerted with a medium hard pressure roller. The end lap will be torched with a gentle flame.

Next, the top layer will be fully torched‐applied on the PROFATHERM BASE SA with a smooth flame of an asphalt torch.

Typical Constructions and U–values

AssumptionsThe U−values in the tables that follow have

been calculated, under a management

system certified to the BBA Scheme for

Assessing the Competency of Persons to

Undertake U–value and Condensation Risk Calculations, using

the method detailed in BS / I.S. EN ISO 6946: 2007 (Building

components and building elements. Thermal resistance and

thermal transmittance. Calculation method) and using the

conventions set out in BR443 (Conventions for U−value

calculations). They are valid for the constructions shown in the

details immediately above each table.

These examples are based on Kingspan Thermaroof® TR27

LPC/FM waterproofed using either a fully adhered single−ply

membrane, mastic asphalt, partially bonded built–up felt, or

under a cold liquid applied waterproofing system. The

insulation board is: fully bonded to a sealed metal deck, or a

vapour control layer, which has itself been fully bonded to the

type of deck stated for each application; or mechanically fixed

through a sealed metal deck, or a vapour control layer, which

has itself been loose–laid directly over the type of deck stated

for each application. The ceiling, where applicable, is taken to

be a 3 mm skim coated 12.5 mm plasterboard with a cavity

between it and the underside of the deck.

NB When calculating U–values to BS EN ISO 6946: 2007, the type of mechanical fixing used

may change the thickness of insulation required. These calculations assume telescopic tube

fasteners with a thermal conductivity of 1.00 W/m.K or less, the effect of which is insignificant.

NB For the purposes of these calculations the standard of workmanship has been assumed

good and therefore the correction factor for air gaps has been ignored.

NB The figures quoted are for guidance only. A detailed U–value calculation together with

condensation risk analysis should be completed for each individual project.

NB If your construction is different from those specified and / or to gain a comprehensive

U−value calculation along with a condensation risk analysis for your project please consult the

Kingspan Insulation Technical Service Department for assistance (see rear cover).

U–value Table KeyWhere an � is shown, the U−value is higher than theworst of the maximum new build area weighted average

U−values allowed by the 2010 Editions of Approved

Documents L to the Building Regulations (England &

Wales), the 2010 Editions of Technical Handbooks

upstand should be used around the perimeter of the roof on

the internal façade of parapets. A minimum distance of

300 mm should be maintained between the top of the

insulation upstand and the bottom of the horizontal roof

insulation. Wall insulation should also be carried up into

parapets as high as the flat roof insulation upstand. Please

FallsThe fall on a flat roof, constructed using Kingspan

Thermaroof® TR27 LPC/FM, is normally provided by the

supporting structure being directed towards the rainwater

outlets. The fall should be smooth and steep enough to prevent

the formation of rainwater ponds. In order to ensure adequate

drainage, BS 6229: 2003 (Flat roofs with continuously

supported coverings. Code of practice) recommends uniform

gradients of not less than 1 in 80. However, because of building

settlement, it is advisable to design in even greater falls.

These can be provided by a Kingspan Thermataper® LPC/FM

tapered roofing system (see below).

Tapered RoofingKingspan Thermaroof® TR27 LPC/FM is also available in a

tapered version, Kingspan Thermataper® TT47 LPC/FM,

comprising a high performance rigid thermoset insulation core,

manufactured with a blowing agent that has zero Ozone

Depletion Potential (ODP) and low Global Warming Potential

(GWP), faced on both sides with a coated glass tissue facing.

Kingspan Thermataper® TT47 LPC/FM comes with

a supporting design service. This ensures that the most

cost−effective solution for a roof is identified and that the end

result is a tapered system design which meets a roof’s

rainwater run−off and insulation requirements. Further details

of Kingspan Thermataper® TT47 LPC/FM are available from

the Kingspan Insulation Tapered Roofing Department (see rear

cover), which should be consulted as early as possible in the

process of designing a roof.

Roof WaterproofingKingspan Thermaroof® TR27 LPC/FM is suitable for use

with most fully adhered single–ply waterproofing membranes.

When using Kingspan Thermaroof® TR27 LPC/FM with fully

adhered single–ply waterproofing membranes, the joints

between boards and cut edges, immediately below the

waterproofing membrane, must be taped with a min. 50 mm

wide foil tape. Please contact the Kingspan Insulation

Technical Service Department (see rear cover) to check

waterproofing membrane and proprietary adhesive system

compatibility. Advice should be sought, from the appropriate

waterproofing membrane manufacturer, in relation to the

requirement for the use of a fleece backed membrane with the

waterproofing membrane in question.

Kingspan Thermaroof® TR27 LPC/FM is also suitable for use

with most bitumen based waterproofing systems including high

performance types which incorporate a Type 3G perforated

base layer to BS 747: 2000 (Reinforced bitumen sheets for

roofing. Specification). The 3G felt layer should be laid dry and

loose, mineral face down with a fully bonded perimeter zone.

Partially bonded built–up felt waterproofing should be laid,

where applicable, in accordance with BS 8217: 2005

(Reinforced bitumen membranes for roofing. Code of practice).


with mastic asphalt waterproofing systems. Mastic asphalt

waterproofing should be laid, where applicable, in accordance

with BS 8218: 1998 (Code of practice for mastic asphalt

roofing). Mastic asphalt should always be laid over an isolating

layer of loose–laid Type 4A sheathing felt to BS 747: 2000

(Reinforced bitumen sheets for roofing. Specification).

The exposed face of insulation upstands, at parapets and

abutments, must be lined with 18 mm exterior grade plywood,

prior to the mastic asphalt waterproofing being laid.

The plywood is used as an anchor point for the expanded metal

substrate onto which the vertical mastic asphalt is laid.

When Kingspan Thermaroof® TR27 LPC/FM is to be used to

insulate balconies, waterproofed with mastic asphalt with a

porous promenade tile overlay, a 20 mm cork roofboard

should be bitumen bonded to the Kingspan Thermaroof®

TR27 LPC/FM prior to laying the Type 4A sheathing felt and

mastic asphalt.


with some cold liquid applied waterproofing systems. When

using Kingspan Thermaroof® TR27 LPC/FM with cold liquid

applied waterproofing systems, a carrier membrane for the

waterproofing must be installed over the insulation boards.

Advice should be sought, from the waterproofing system

manufacturer, about the specification of the carrier membrane

and the compatibility of the waterproofing system with

Kingspan Thermaroof® TR27 LPC/FM. For further advice

please contact the Kingspan Insulation Technical Service

Department (see rear cover).

NB Kingspan Thermaroof® TR27 LPC/FM is also suitable for use with mechanically fixed

single–ply waterproofing membranes.

34

Water Vapour ControlKingspan Thermaroof® TR27 LPC/FM should be installed over

a separate vapour control layer, in new build roofs, unless it is

being used in conjunction with a sealed metal deck.

Regardless of the deck type it is recommended that a

condensation risk analysis is carried out for every project.

For refurbishment projects, involving the addition of insulation

to existing insulated flat roofs, or roofs constructed of insulated

steel faced composite panels, it is imperative that a

U–value calculation and condensation risk analysis is carried

out for every project, in order to ensure that the correct

thickness of insulation is installed to achieve the required

thermal performance, whilst avoiding interstitial condensation.

In refurbishment projects, where Kingspan Thermaroof® TR27

LPC/FM is to be installed over an existing bituminous

waterproofing membrane, the membrane can be used as a

vapour control layer, as long as it is in a good water tight

condition. Where this is not the case, a separate vapour

control layer should be installed.

The type of separate vapour control layer required will be

dependent upon the chosen method of fixing the insulation

boards.

For mechanically fixed applications, a minimum vapour control

layer should consist of a 1000 gauge (250 micron) polythene

sheet, with all joints lapped and then sealed with double sided

self adhesive tape.

For applications where the insulation boards are to be bonded

to the vapour control layer, a minimum vapour control layer

should consist of a coated roofing felt complying with Type 3B

to BS 747: 2000 (Reinforced bitumen sheets for Roofing.

Specification), or S1P1 to BS 8747: 2007 (Reinforced bitumen

membranes (RBMs) for roofing. Guide to selection and

specification), or any appropriate metal–cored vapour control

layer.

Where the separate vapour control layer is to be bonded,

allowance should be made for adequate bonding of the vapour

control layer to the substrate, so as to provide a suitable

surface upon which to lay the insulation boards and sufficient

resistance to wind up–lift (see ‘Wind Loading’).

Roof Loading / TrafficKingspan Thermaroof® TR27 LPC/FM is suitable for use on

access roof decks subject to limited foot traffic.

Where inappropriate foot traffic is liable to occur, it

is recommended that, for roofs waterproofed with mastic

asphalt, a 20 mm cork roofboard is bitumen bonded to the

Kingspan Thermaroof® TR27 LPC/FM prior to waterproofing,

and the roof surface is protected by promenade tiles.

Where inappropriate foot traffic is liable to occur, it is

recommended that, for roofs waterproofed with partially

bonded built–up felt, the roof surface is protected by

promenade tiles.

Where inappropriate foot traffic is liable to occur, it is

recommended that, for roofs waterproofed with fully adhered

single–ply or cold liquid applied waterproofing systems, the

roof surface is protected by specially constructed walk–ways.

For further advice on the acceptability of specific foot traffic

regimes, please contact the Kingspan Insulation Technical

Service Department (see rear cover).

Green RoofsKingspan Thermaroof® TR27 LPC/FM is suitable for use

under most green roof systems.

Green roof systems are a specialist design area.

When designing a loose–laid insulated green roof assembly

consideration needs to be given to the following.

Green roof systems are required to have a minimum dry weight

of 80 kg/m2 to ballast the insulation boards beneath them.

However, the total required dry weight will depend upon wind

uplift, which in turn will vary with the geographical location of

the building, local topography, and the height and width of the

roof concerned. The necessity for any additional dry weight

should be assessed in accordance with BS 6399−2: 1997

(Loading for Buildings. Code of practice for wind loads) or

BS / I.S. EN 1991−1−4: 2005 (National Annex to Eurocode 1

Actions on structures. General Actions. Wind Actions).

When installing a loose–laid insulated green roof assembly,

any insulation must be immediately over–laid with the green

roof system, which must meet all of the requirements

outlined above.

Where these requirements cannot be ensured, the insulation

must be mechanically fixed (see Sitework). For further

information please contact the Kingspan Insulation Technical

Service Department (see rear cover).

Board Size Selection� If consideration is being given to bonding Kingspan

Thermaroof® TR27 LPC/FM, either in hot bitumen or with

the use of a suitable alternative proprietary adhesive

system, it is recommended that 1.2 x 0.6 m boards

(in Britain) or 1.2 x 1.2 m boards (in Ireland) are used.

� All sizes of board are suitable for mechanical fixing.

Installing over Metal Decks� Where an FM or LPCB approved construction is required,

please refer to ‘LPCB & FM Certification’ on page 14.

� Metal decks should be clean, dry, without large

projections, steps or gaps, and should be graded to allow

correct falls to all rainwater outlets.

� If using a sealed metal deck there is no requirement for a

separate vapour control layer.

� If the metal deck is not sealed, and the insulation boards

are to be bonded down, in order to ensure an adequate

bond between the metal deck and the vapour control

layer, the metal deck should be suitably primed,

in accordance with the primer manufacturer’s instructions,

prior to the application of the hot bitumen, or suitable

alternative proprietary adhesive system, used to bond the

vapour control layer to the deck.

� If the metal deck is not sealed, and the insulation boards

are to be mechanically fixed, the vapour control layer

should be loose–laid.

� Where one run of the specified vapour control layer laps

another, there should be minimum 150 mm side and end

overlaps, which should be adequately sealed.

� Turn up the vapour control layer at the edge of the roof

to a height appropriate to the specified waterproofing

membrane.

� Boards of Kingspan Thermaroof® TR27 LPC/FM should

be secured to the deck using mechanical fixings e.g.

telescopic tube fasteners (see ‘Mechanical Fixings’).

� Alternatively, the insulation boards should be bonded down

by laying into hot bitumen (max. temperature 240°C)

mopped or poured over the vapour control layer / sealed

metal deck, or with the use of a suitable alternative

proprietary adhesive system.

� Insulation boards should always be laid break–bonded,

either with their long edges at right angles to the trough

openings, or diagonally across the corrugation line, and

with joints lightly butted. There should be no gaps at

abutments.

� Roof–light or ventilator kerbs etc. should always insulated

with the same thickness of Kingspan Thermaroof® TR27

LPC/FM as the general roof area.

� A 25 mm thick Kingspan Thermaroof® TR27 LPC/FM

upstand should be used around the perimeter of the roof

on the internal façade of parapets.

� A minimum distance of 300 mm should be maintained

between the top of the insulation upstand and the bottom

of the horizontal roof insulation.

� The waterproofing membrane is installed in accordance

with the membrane manufacturer’s instructions, over the

whole insulated area including any insulation upstands, as

soon as possible after laying the insulation boards.

Installing over Concrete Decks� Concrete decks should be clean, dry, without large



� If the insulation boards are to be bonded down, in order to

ensure an adequate bond between the vapour control

layer and the concrete deck, the concrete or screeded

surface should be suitably primed, in accordance with the

primer manufacturer’s instructions, prior to the application

of the hot bitumen, or suitable alternative proprietary

adhesive system, used to bond the vapour control layer to

the deck.

Installing over Plywood Decks� Plywood decks should be clean, dry, without large



� If the insulation boards are to be bonded down, in order

to ensure an adequate bond between the plywood deck

and the vapour control layer, the plywood surface should

be suitably primed, in accordance with the primer

manufacturer’s instructions, prior to the application of the

hot bitumen, or suitable alternative proprietary adhesive

system, used to bond the vapour control layer to the deck.

� Alternatively, the vapour control layer can be nailed to the

deck, in which case the nail heads will become sealed with

the subsequent bonding of the insulation boards to the

vapour control layer.

� If the insulation boards are to be mechanically fixed, the

vapour control layer should be loose–laid.

� Joints between insulation boards should not coincide with

those between the plywood sheets.











Installing over Existing Flat Roofs� The existing waterproofing membrane surface should be

clean, dry, without large projections, steps or gaps, and

should be graded to allow correct falls to all rainwater

outlets.

� Where the existing waterproofing membrane is not fit for

purpose as a vapour control layer, and the new insulation

boards are to be bonded down, a separate vapour control

layer should be bonded to it with hot bitumen, or suitable

alternative proprietary adhesive system. If the insulation

boards are to be mechanically fixed, the vapour control

layer should be loose–laid.




� Turn up the vapour control layer at the edge of the roof to

a height appropriate to the specified new waterproofing

membrane.

Mechanical Fixings� The number of mechanical fixings required to fix

Kingspan Thermaroof® TR27 LPC/FM will vary with the

geographical location of the building, the local topography,

and the height and width of the roof concerned along with

the deck type.

� A minimum of 4 fixings are required to secure 1.2 x 0.6 m

boards of Kingspan Thermaroof® TR27 LPC/FM to

the deck.

the deck.

� The requirement for additional fixings should be assessed

in accordance with BS 6399–2: 1997 (Loadings for

buildings. Code of practice for wind loads) or BS / I.S.

EN 1991−1.4: 2005 (National Annex to Eurocode 1.

Actions on structures, General Actions, Wind Actions).

� Mechanical fixings must be arranged in an even pattern.

� Fasteners at insulation board edges must be located

> 50 and < 150 mm from edges and corners of the board

and not overlap board joints.

� Please refer to page 13 for recommended fixing patterns.

� Each fixing should incorporate a square or circular plate

washer (min. 50 x 50 mm or 50 mm diameter).

� If two layers of insulation are to be installed, the base layer

should be mechanically fixed with minimum 1 No. fixing in

the centre of the insulation board before fixing the top layer

as described above.

� Where alternative mechanical fixing systems are specified,

such as bar fixing systems, the specified system must give

similar restraint to the insulation board as would be attained

by the use of conventional telescopic tube fasteners.














Installing over Existing Composite

Panel Roofs� If the existing profile provides inadequate support for the

insulation boards, the existing roof should be

over–boarded, e.g. with plywood, prior to their installation.


be secured to the deck using mechanical fixings.

Please refer to the Kingspan Insulation Technical Advice

Service (see rear cover) for advice on fixing specification.

� Insulation boards should always be laid break–bonded and

with joints lightly butted. There should be no gaps at

abutments. If the existing roof has been over–boarded,

then insulation boards should be laid with their long edges

at right angles to the edge of, or diagonally across the

roof. If not, they should be laid either with their long edges

at right angles to the trough openings, or diagonally across

the corrugation line.

38

GeneralFollowing Trades

� The roof must be adequately protected when building

works are being carried out on or over the roof surface.

This is best achieved by close boarding. The completed

roof must not be used for storage of heavy building

components such as bricks or air conditioning equipment.

Reflective Coatings

� Bitumen based built up waterproofing systems laid over

Kingspan Thermaroof® TR27 LPC/FM should always

incorporate a solar reflective layer such as chippings or a

specialist coating.

Daily Working Practice

� At the completion of each day’s work, or whenever work

is interrupted for extended periods of time, a night joint

must be made in order to prevent water penetration into

the roof construction.

Cutting

� Cutting should be carried out either by using a fine

toothed saw, or by scoring with a sharp knife, snapping

the board over a straight edge and then cutting the facing

on the other side.

� Ensure accurate trimming to achieve close–butting joints

and continuity of insulation.

Availability

� Kingspan Thermaroof® TR27 LPC/FM is available

through specialist insulation distributors and selected

roofing merchants throughout the UK and Ireland.

Packaging and Storage

� The polyethylene packaging of Kingspan Insulation

products, which is recyclable, should not be considered

adequate for outdoor protection.

� Ideally, boards should be stored inside a building.

If, however, outside storage cannot be avoided, then

the boards should be stacked clear of the ground and

covered with an opaque polythene sheet or weatherproof

tarpaulin. Boards that have been allowed to get wet

should not be used.

Health and Safety

� Kingspan Insulation products are chemically inert and

safe to use.

� A Safety Information Data Sheet for this product is

available from the Kingspan Insulation website

www.kingspaninsulation.co.uk/safety or

www.kingspaninsulation.ie/safety.

Warning – do not stand on or otherwise support your weight on this board unless it is fully

supported by a load bearing surface.

11

Installing in Two Layers� In situations where two layers of insulation are required,

both layers should be installed in the same manner, as

detailed in the preceding sections. However, if mechanical

fixing methods are to be employed, refer to ‘Mechanical

Fixings’ for guidance on the number of fixings to be used

in each layer.

� In all cases, the layers should be horizontally offset

relative to each other so that, as far as possible, the board

joints in the two adjacent layers do not coincide with each

other (see Figure 6).

Thermal Properties

The λ–values and R–values detailed below are quoted

in accordance with BS / I.S. EN 13165: 2008 (Thermal

insulation products for buildings – Factory made rigid

polyurethane foam (PUR) products – Specification).

Thermal Conductivity

The boards achieve a thermal conductivity (λ–value) of:0.025 W/m.K (insulant thickness 80 – 119 mm); and

0.024 W/m.K (insulant thickness ≥ 120 mm).

Thermal Resistance

Thermal resistance (R–value) varies with thickness and is

calculated by dividing the thickness of the board (expressed

in metres) by its thermal conductivity. The resulting number is

rounded down to the nearest 0.05 (m2.K/W).
