Welcome to the latest issueof SIP News Magazine –providing you with updatesand developments in the lowenergy building arena.
It is fair to say that theconstruction industry haswitnessed a significant rise inthe use of Structural InsulatedPanels for use in the erection ofboth residential and commercialbuildings in recent times, withinterest levels hitting a constantupward trajectory now that‘fabric first’ principles areunderstood and being adoptedacross a broad spectrum ofbuilding types.
It is widely acknowledged thatSIP technology provides verythermally efficient buildings witha much improved airtightness,contributing significantly toenergy conservation and carbonreduction, whilst providingexcellent performance whenassessed against the relevantbuilding standards. In addition tothese features, the improvementsin the speed of construction aresignificant too. These attributes
are explored in this issue of SIPNews through technical articlesand case studies.
The UK SIP Association providesinformation required by themarket on SIP construction in abroader context and over recentmonths we have been preparingthe latest Technical Bulletin onSustainability, which I am nowpleased to say has now beenpublished. We have also beenimplementing the SIPCheckInstaller Accreditation Schemeand developing the SIPS Codeof Practice – all of which iscovered in this issue of SIPNews. In parallel we havecontinued to recruit newMembers and to develop ourportfolio of SIPS project casestudies to help to inspire andencourage the greater uptake of SIPS technology.
In September we successfullyparticipated in Timber Expo –hosting the Toolbox Talksseminar theatre and contributedto the ProTimber Summit incollaboration with our TimberAccord partners. Strategic
developments across the sectorlook very interesting as werespond to the GovernmentsConstruction Strategy 2025,which we are well placed to do.
We would encourage anyoneassociated with SIP supply ormanufacture, specification,design or construction toengage with us via our website -www.uksips.org. We have awealth of information online plusmember search tools, casestudies, technical bulletins, a project enquiry system andmuch more!
We hope you enjoy theread…and would appreciate yourfeedback on this issue of SIPNews via [email protected]. If youwould like to contribute to futureissues of SIP News then pleaseget in touch.

Construction Products Association and UKTI to Promote Export Opportunities
The Construction ProductsAssociation has been awardedfunding from UK Trade &Investment for a two year projectto identify and assist more non-exporting companies in theconstruction products sector to start exporting. This projectbuilds on the Association’ssuccessful overseas exhibitionand mission programme whichhas helped more than 200companies break into newoverseas markets in the lastthree years.
The first stage of the exportproject is a short survey toassess the extent of existing and potential export activity.Association Export ManagerMike Josypenko explains: “We would like to hear from allmanufacturers and suppliers ofconstruction products, exportersand non-exporters alike, to getyour views on exporting, hearabout your successes, thechallenges you face, and whatsupport you need to startexporting. The survey will also
identify a pool of companies whowish to receive practical helpfrom the Construction ProductsAssociation to sell their productsand services overseas.”

industry news Business leaders unite with letter to PM on energy bills
Leaders from more than 50 ofthe UK’s leading companies andprofessional institutes operatingin the built environment,including the Structural TimberAssociation and the TimberTrade Federation have warnedthe Prime Minister not to scaleback so called green levies onenergy bills.
In a letter to David Cameroncoordinated by the UK GreenBuilding Council, chiefexecutives from a range of firmsincluding E.ON, Carillion, BarrattDevelopments, Willmott Dixonand Keepmoat, are urging theGovernment not to scale backschemes such as the EnergyCompany Obligation (ECO) in a bid to reduce consumers’energy bills.
The letter argues that energyefficiency is the “only sure way”
to protect households againstrising bills in the long-term, andthat rolling back ECO, which isdesigned to improve the energyefficiency of vulnerable and lowincome households and ‘hard totreat’ properties, would insteadincrease energy bills for theseconsumers and have “severeconsequences” for jobs in the sector.
The leaders also urge MrCameron to consider usingadditional incentives such asStamp Duty to encourage uptakeof the Green Deal, which couldhelp reduce the cost of ECO.Paul King, Chief Executive of theUK Green Building Council, said:“Business leaders are sending a powerful message to DavidCameron – do not scrap theEnergy Company Obligation.Cutting back schemes designedto boost energy efficiency is an
incredibly short-sighted view andone that will only result in higherbills in the medium to long-termfor those most vulnerable fromrocketing energy prices.“Energy efficiency is the onlyguaranteed way to combat risingenergy bills and it defies beliefthat the Prime Minister isconsidering ‘rolling back’ one of the Government’s biggest initiatives to achieve this.”

Code Level 4 offsite houseto 'disrupt the norm'
Stephen McCready, a formerdeveloper in Northern Irelandand pioneer of carbon neutralhousing, has been backed by aSwiss investor to bring a newhousing system to market calledNühaus, which allows a two-storey, three-bedroomed houseto be built in a day. Two semi-detached houses will be built onthe BRE’s Innovation Park andwill be designed to meet Level 4of the Code for Sustainable Homes.
The housing system featuresbespoke structural insulatedpanels that can achieveairtightness values of 1.2m3/hr/m2@50Pa. The fully rigidmodular solution arrives onsitefully painted, decorated,plumbed, wired and with kitchen,bathroom, windows and doorsinstalled and fitted.
Nühaus managing directorMcCready said: “We build oursuper energy efficient houses ina factory, so you don’t have tobuild them in the rain any more,all our houses are Code Level 4as standard, and can beupgraded to 5 or 6 if required.”
Twelve houses have alreadybeen built using the system attwo sites in Scotland. JohnO’Brien, a principal consultant atthe BRE, said building to CodeLevel 4 is very difficult usingtraditional building techniques,so by manufacturing all thecomponents in a factory you can
control the quality and ensureairtightness. Modular panelsarrive on truck alreadywaterproofed, so there is noneed to install a membrane.Plumbing and services pre-fitted.Houses can be erected in a day,and around 10 days includingthe roof.
Nühaus will be initially aimed athousing associations. O’Briensaid the cost was around £600-£700 per sq m, plus foundationcosts. “Most housingassociations tend to aim foraround £1,000 per sq m withsocial housing. So with thishouse Code 4 isn’t really costing any more than we were achieving Code 3 with.”
A new factory-built house, which its inventor claims will “disrupt the convention of house building in the UK”, is to be launched in the UK this Autumn.
The affordable housingexemplar was officially openedat the INSITE 13 sustainabilityconference on 2 October at BRE Watford.See www.insite13.com

Businesses in the North Eastwere hoping for a capitalinjection when their floatingadvert, the racing vessel OneHull of a Boat, arrived in London.Its mooring at Docklands onSeptember 21 was anopportunity to tell aninspirational story of vision,pluck and opportunism that it’shoped will open doors in theSouth East. The spot in EastLondon put it next to CanaryWharf where it could best gainglobal media awareness andseize networking and partneropportunities for the region.
Sponsors SipBuild UK helpedthe audacious idea come true bypitching in with schools,charities and individuals to makeup the £24,000 required to buythe 28 ft P1 Panther. The 250hpvessel would normally cost£80,000 but a logistical mix upmade for a knockdown price.The idea was the boat wouldtour the UK – and be broadcastaround the world on Sky Sports– racing and promoting the Hullbusiness community.
SipBuild UK has also beenshortlisted in the Build ItMagazine awards for its workwith SIPS. It will discover if it haswon the Best Use of SIPscategory at an event hosted byTV comedian Alan Davies fromQI and Jonathan Creek onNovember 21 beside theNational Self Build & RenovationCentre in Swindon.
SipBuild UK Managing DirectorChris Duckworth said: “It’s greatto be recognised as one of thebest in the country for what wedo. We’re up against three toughcompetitors but we have a verygood chance as our entry isbased on a case where the self-builder was also a professionalbuilder. Despite planning atimber frame for a first floorextension to his bungalow hechose SIPs after learning howtheir strength and low weightwould skip all sorts of labourincluding new work on thefoundations.
“In terms of innovation anddesign, our project is a fantasticexample of how SipBuild UKworks with existing structuresand complements them in the
most efficient way possible. Self-builders naturally want to knowwhat a professional builderwould use on their own home -well, this is the answer!”
The extension SipBuild UK builtwas six times stronger than atimber frame with unbeatablethermal efficiency, yet noadditional support was neededabove the ground, adding morespace to the five per cent extracreated by slim-line SIPscompared to traditionalconstruction methods. SipBuildUK were on site for just ninedays, with the floor and walltaking five days and the rooffour. The entire extension projectlasted just three weeks.

A panel of judges drawnfrom the constructionindustry, major companies,universities and industrybodies said that the projectshowed: "Great use ofoffsite manufacturing,community and clientengagement and apassionate team leading an engaged supply chain."
Completed on behalf of LeedsCity Council, the school uses upto 80 per cent less energy than a conventionally-built, equivalent-sized facility. Its carbonemissions are also 60 per centreduced without having to includea source of renewable energy onthe development. Instead, theschool follows Passivhaus designprinciples to create the most
efficient building envelope for thermal performance andairtightness, supported byoptimum heat recovery systems.
The single- and two-storey steel-framed building providesaccommodation for a three-formentry primary school, nurseryand Autistic Spectrum ConditionUnit. Offsite-manufactured, SIPSare used for wall and roofconstruction that combine highquality manufacture with excellentairtightness. In other parts of the building, greater energyefficiency has been achieved by reducing the effects of cold-bridging that encourages heat loss.
Passivhaus-certified high-efficiency air-handling units havealso been installed and air testshave revealed that the finaltightness of the building is 20times better than that required by Building Regulations. Despitethese high standards, the project
was also built to budget anddelivered two weeks ahead of programme.
It is estimated that if Leeds CityCouncil were to convert all 177schools to Passivhaus-certifiedbuildings, then a saving of £4.6million per year would be realisedsolely in energy savings, againstan estimated current spend of £7.4 million per year.Ian Renhard, MD Construction at Interserve said: "Winning thisprestigious award and beingrecognised by such an esteemedand knowledgeable panel ofjudges is testament to the skillsof the project team and the abilitywe have to use innovations tosolve problems for our clientsand make significant savings by adopting the most energy-efficiency build standards."

The Code for Sustainable Homes & Passvihausshould not to be confused. They are both differentassessment systems and should be viewed ascomplementary more than competitors.
The Code for Sustainable Homes(CfSH) is an overarching systemfor newbuild residential housing,which considers the sustainablefeatures from nine headlinecategories (Energy, Material,Waste, Water, Surface Water,Pollution, Health & Well Being,Management and Ecology), andrates a property from Level 1 toLevel 6 with mandatory levels ofperformance pertaining to thecode level required/achieved.SIPS technology has the potentialto impact on credit awards inmany of these categories,especially Energy, Material,Waste, Pollution and Health & Well Being.
CfSH does not tell you a solution,it merely tells you how theunit/development rates.Passivhaus is a system of designcentred on the performance ofthe building envelope. It sets out a distinct set of parameters forconstruction, resulting in anexemplar performing unit with lowenergy demand and low energywasted (not just for houses).
The two systems are not mutuallyexclusive, in fact the benefit ofthe use of Passivhaus principlesare echoed strongly in theevolution of CfSH, with the mostrecent revision (Nov 2010),allocating 22% of the total creditsavailable to the categories directlyaffected by Passivhaus – DwellingEmission Rate (DER) & FabricEnergy Efficiency (FFE). Thisallocation is not a coincidence, as through the revisions of theCfSH since it subsumed BRE’sEcoHomes as the leading UK
sustainable assessment systemfor houses, the change ofemphasis has clearly beentowards rewarding a Fabric Firstsolution and away from the initialneed to show off your eco-credentials with solar panels or photovoltaics (PV).Underlined by the changes to Part L1 of The BuildingRegulations 2010 (in England & Wales) , and likely to be re-enforced in imminent andsubsequent updates, it is now
understood that it is better not to need or waste the energyrequirement in the first place,than it is to replace it – stepforward Passivhaus.
Until now CfSH assessments havebeen dominated by the need toachieve Code Level 3, oftendictated by funding requirementsand in energy/CO2 since 2010this has meant no more thanachieving Building Regulationcompliance (Dwelling EmissionRate ≤ Target Emission Rate).However, higher Code Levelsrequire a significant reduction in DER, and with CfSH’s need to accumulate credits too, FEEhas become a stronger focus/driver for clients looking for value rather than kudos.
Working on the same approachas Passivhaus principles, designsfocus on improved fabricperformance with better thanrequired U-values, attention to thermal bridging details (whose impact is not to beunderestimated), consideration to solar-gain, ventilation and heatrecovery methods, and improvedairtightness, all now common andunderstood terms around thedesign table.
Pitching a strong envelope hasnever been more relevant, andeven though CfSH might not lastmuch longer in its current formand Passivhaus might neverbecome enforced, it is undeniablethat these systems both providestrong clues to the direction thatUK Building Regulations willcontinue to take, as legalcommitments to carbon emissionreduction continue.

NEC BIRMINGHAM24&25 SEPTEMBER 20I3
Organisers of Timber Expo announcedthe 2013 exhibition was the mostsuccessful in the event’s three yearhistory. With a relocation to Birmingham’sNational Exhibition Centre, the event was a perfect opportunity for everyoneinterested in timber to gather in one spot to hear about where the material isheading and how it can used across anincreasingly diverse built environment.
Innovation was at the heart of the eventand reflecting recent research fromTRADA that polled (from 170 respondentsasked) which areas were of most interestto them, ‘new, innovative products andsystems’ scored higher than any othertopic. The Timber Talks programmedelivered some of the biggest names inthe industry discussing many of theseinnovative topics.
TALKSTOOLBOX
Organised by TRADA, the 2013Timber Talks programme drew ina huge pre-registered audienceof architects, designers,engineers and contractors. Theexceptional line-up includedspeakers from Arup, Architype,BDP Architects, Bailey Garner,Land Securities, Mace, Price &Myers, Ramboll UK, RichardsPartington Architects, WillmottDixon and Waugh Thistleton.Rupert Scott, Marketing &Membership Manager for TRADAsaid: “The new Timber Talksformat went down well withvisitors and the chairmen allreported lively and engagingQ&A sessions because the Talkshad great content and weredelivered by people who knewtheir subject well.”
Complementing the Timber Talksprogramme, the Toolbox Talkswere held in a purpose built 30-seat presentation theatresupplied by the UK SIPAssociation. From manufacturingprocesses to onsite engineering
solutions, the Toolbox Talksseminars and workshops werededicated to timber technologyand focused on the detailsbehind many of the processes,technologies and solutions ondisplay at the show.
Next year is also set to be aspecial one. As Timber Expo will be co-locating with the W14exhibition to bring visitors to theNEC an unrivalled opportunity to connect with the entire timberindustry in one single venue.W14 is the national exhibition for joinery and furnituremanufacturers in the UK andoffers a natural synergy withTimber Expo. This move hasbeen welcomed by the manyvisitors who would like to seeboth shows in a single visit.
Event Director, Loretta Salessaid: “Moving Timber Expo to theNEC proved to be a sounddecision, with a total 4,611visitors attending the exhibition –a 9% increase on 2012. There
was a real buzz around theevent, with a definite increase in international visitors, sometravelling from as far afield asBolivia, Nigeria and Malaysia.The real test of an event’ssuccess are the re-bookings and 58% of exhibitors signedcontracts at the show for the2014 exhibition.

With BIM, embodied energy andenergy consumption plus how tobuild ‘smarter’ on the agenda,Mark Wakeford, ManagingDirector of Stepnalls and advisoron the development of theConstruction Strategy 2025, put the session into perspectivesaying: “Business and theconstruction industry ischanging so fast that a co-ordinated response is requiredby the timber sector especiallyas sustainability issues and thecost of energy keeps rising, thewhole industry needs to acttogether to cope as there is adanger that the UK will lose outto the many talented overseasoperators and companies.”
A key market will be in retrofit,with so much work in theconstruction market being inrepair, maintenance andimprovement (RMI) – estimatedto be 90% – a smart agenda tolow carbon design and deliveryis essential to make timberproducts and systems be anintegral part of the greenbuilding mix. Through continuedcollaboration and meaningful
leadership, the Accord members(and industry associationsindividually) will be workingtogether to prove that timber has enormous low carbonbenefits, a raft of dynamic highperformance products and via improved BIM data willcontribute in helping make theUK Government’s ConstructionStrategy 2025 commitments a reality.

The recently launched Structural TimberAssociation (STA) is engaging with UKhousebuilders to encourage greateruptake of timber within construction.
UK SIPS Collaboration Partner STA Ready to Engage Housebuilders
Lawrence Young STA Chairman
21
Through rolling out a series offactory and site tours withindustry engagement, the STAaims to engage directly withhousebuilders and increaseunderstanding of the benefits of timber construction. TheAssociation has invited industryleaders to the factory tours at a number of member locationsacross the UK, which willsupport its industry incapitalising on the current upturn.
With timberframe accounting for only 18% of new homes inEngland and Wales, there is areal opportunity to increase thenumber built using this form ofconstruction which offers bothspeed of build and energyefficiency. As many builders are looking to capitalise on themarket increase, timber offers a readily available alternative tomore traditional build methods.
Speaking about the initiative,chairman of the STA, LawrenceYoung says: “Private developershave historically looked to thetimber industry to shorten timeto market and provide morestable and predictable buildingprograms. With the slow andsomewhat fickle marketconditions experienced over the past few years, fast buildprograms haven’t been at thetop of everyone’s agenda.
However, we’re now seeingdevelopers needing to react tochanges in market conditionsand bring new sites to marketquickly. “On top of this pressure,as we head towards the wintermonths, there is the added issueof poor weather conditions. Last year, many developersexperienced delays on sitebecause of the weather, withprograms ending up between six and twelve weeks behind -leading to missed marketopportunities and extra costs to get homes ready for sale. The answer to this problem issimple: a move to building instructural timber.
Lead-times can be reduced byfour weeks on an average sizedhouse and build programsbecome predictable - almostirrespective of weather relatedissues. While timber frame won’teliminate all delays it willcertainly shorten time to marketand ensure developers havehomes for sale at the right time.”
The tours will take place at the following locations throughoutNovember and December:

Ensuring long termdurability, good in-serviceperformance, ease ofmaintenance and modificationas well as considering theimpact of the constructionprocess itself are all veryimportant factors whenconsidering sustainableconstruction. SIPs offer arelatively low embodied energybuilding system with good longterm thermal and airtightnessperformance and are also ableto offer a long design andservice life.
For construction to besustainable, the basic principlesof sustainable developmentmust be adopted. The UKGovernment's strategy for moresustainable construction widensthe basic themes to suggest keyactions by the constructionindustry. These includedesigning for minimum waste,lean construction, minimisingenergy use in construction and avoiding pollution.
Key areas covered in theUKSIPs Sustainability TechnicalBulletin include:
Materials used in SIPsSIPs are constructed bylaminating layers of OrientedStrand Board (OSB) to an
insulating foam core. Most, if not all, OSB used in themanufacture of SIPs will comefrom manufacturing plants in theUK or Europe and will be madefrom sustainably sourcedsoftwood timber. Sustainabletimber will come from managedforests and will be certified byan organisation such as FSC orPEFC. SIPs generally achieveBRE Green Guide ratings of A and A+ for wall and roofelements.
Manufacture of PanelsStructural Insulated Panels areconstructed in two main ways:one is to bond sheathing boardsto blocks of expanded orextruded polystyrene, most
commonly using solvent freepolyurethane adhesives. Theother method is to inject liquidfoam insulation between twoboards, allowing it to expand and adhere to the boards under pressure.
Whole Life CostsMany SIP buildings use theFabric First approach toreducing carbon dioxideemissions. Rather than offsettingenergy usage (and carbonemissions) with bolt ontechnology, the heating (andcooling) demands of the building are reduced to thelowest levels practically possible through insulation and airtightness.

Additional SavingsSIP structures are typically low inweight and so additional savingsin embodied energy can bemade in the design offoundations and supportingstructures through the use ofless concrete. Similarly the useof SIPs may allow sites to beused that were not deemedsuitable for typical masonryconstruction, e.g. sites with poorground conditions.
Release of dangerous substances VOCs and formaldehyde off-gassing of dangeroussubstances is a topic which thepublic is starting to become moreaware of. SIPs consist of OSBand foam insulation. OSB ismanufactured from strands ofsoftwood timber and adhesiveresins. The resins used in theproduction of OSB are typicallyphenol formaldehyde; however theoff gassing from this type of
adhesive is minimal and thequantity used is very low.
Building modification,extension and repurposingAs the needs of buildingoccupants change over time,homes are modified to fit withthe aesthetic desires or practicalrequirements of the owners. SIPsare still relatively new to theconstruction industry and sothere is less general knowledgeabout undertaking modificationsto these structures, althoughthey are no harder to modifythan other types of building.
Deconstruction and recyclingof old buildingsAt the end of a buildings life, it isimportant to try and reuse andrecycle as many componentsand materials as possible. Thereare many organisations and localcompanies that specialise in thereclamation and sale of buildingmaterials.

Traditional Oak with acontemporary twist in theheart of Worcestershire
Martin and Helena Glosterappointed SIPS UK to supplyand erect a SIP envelope overthe top of their Oak Frame. Thiswas to be their retirement homeand they were only too awareof the ever increasing energycosts which is why, afterseveral pricing options, theychose to use our 175mm SIPpanel for both the walls and theroof, giving a U-value of 0.14W/m²K for the panel onlyaspect. Unfortunately for theclient this method of build isexpensive as they were payingfor two structural systems - inaffect the oak frame is strongenough to cope with all theimposed loads, but is not awalling system. The SIPs forthis type of application aremainly being used as claddingpanels and to carry the externalfinishes. The SIPs are thereforenot being fully utilised to fullpotential.

Self-build residential project in Solars Hope, Herefordshire
Following an unfortunate fire, Mrs Christine commissioned FutureTech to rebuild her home. Situated in the picturesque village of SolarsHope in rural Herefordshire the site offered exceptional views of threeBritish counties.
The new SIP’s home was designed to match the dimensions andaesthetic of the original property, while using modern build techniquesto reduce the build time, improve energy efficiency and offerincreased air tightness.
Our client was, at the time, living in a caravan on site. A fastconstruction time was imperative, consequently the Future-Tech teambrought in extra craftsmen from sites where they could be sparedand commenced with the build as soon as possible.

Passivhaus Visitor Centre in Telford
This was to be a new flagship construction project, a part of a newtown centre development in Telford, and the first Passivhaus schemein Shropshire.
The brief was to construct a new Visitor Centre in Telford TownPark to comply with Passivhaus standards.
The building had been developed prior to Lowfield involvement using a Modular Straw Bale wall system and a SIPS roof. As a localsupplier of Structural Insulated Panel Systems, we were invited to discuss the project and tender for the supply of materials.
At that stage however, the overall project cost was still considerablyhigher than the budget and cost savings were required to deliver thescheme at the required level of thermal performance and withoutcompromising the aesthetics of the building.

Large three-bedroom self-build bungalow
Mrs Vowles contracted SIPsEco Panels to do the designand to supply the panels on her energy efficient bungalow.
Her brief was for a large threebedroom bungalow tocomplement the neighbouringbuilding externally and withlarge spaces inside that couldbe opened or closed up ifneeded.
SIPs Eco Panels used theirsister company Custom Homesto prepare the architecturaldesign and apply for planningpermission.
Mrs Vowles used a projectmanager who SIPs Eco Panelsput her in contact with andwhen our erectors arrived onsite, they erected the full frameand roof in just nine workingdays, much to the delight of the client who could thenstart work on the inside of the build.

Residential property extension in a flood zone
Our client had a good sized rambling rural property which had a large extension. The client wanted to demolish this very old anddraughty extension and rebuild it using an energy efficient method of construction.
There were two complications. One being that it was an undulatingsite and more complicated was that the build had to includesubstantial flood protection works due to its location close to a river.
This was a challenge that the SIPs Eco Panels team welcomed andoffered the services of their sister company Custom Homes toprepare the architectural design.
SIPs Eco Panels were contracted to provide Building Regulationdrawings and supply and fit 194mm SIPs Eco Panels for the wallsand roof.

The construction industry is undergoing majorchange. 01 July 2013, saw the ConstructionProducts Regulation 2011 come fully into forcemaking it mandatory for manufacturers ofconstruction products covered by a harmonisedEuropean Standard (hEN), or conforming to aEuropean Technical Assessment (ETA) that hasbeen issued for their product, to establishappropriate measures for the CE Marking of theirproducts when placing them on the market withinthe EU.
The CE Mark (formerly known as the EC Mark), is a mandatory conformity marking for certainproducts sold within the European Economic Area(EEA), consisting of the 28 member states of theEuropean Union (EU) and European Free TradeAssociation countries – Iceland, Liechtenstein and Norway.
The CE Mark is also found on products sold outside the EEA, because they are either productsmanufactured in the EEA and have been exported,or they were manufactured in other nations whichhave the EEA as a prime market. This makes the CEMark recognisable worldwide. A CE Mark consists of the CE-Logo and if applicable, the four digitidentification number of the Notified Body involved in the conformity assessment procedure.
Who Does it Apply to?The CE Mark is the manufacturer’s declaration thatthe product meets the requirements of the applicableEC Directives. In the construction sector, these comein the form of the Construction Products Regulation(CPR). As this is a Regulation, it automaticallybecomes law in all EU member states and says thatfrom 01 July 2013 all products within scope of aharmonised European Standard (hEN) must be CEmarked to that standard by 01 July 2014.
CE MARKING- understanding the basics Getting to grips with CE Marking is essential for anyone designing, manufacturing, importing or distributing certain products that are destined for theEuropean Market. Steve Weaver of Cogent Consultingexplains the fundamentals of achieving compliance and why you ignore it at your peril…
- the voice of the UK SIP industry
32
Any business therefore, eitherinside or outside the EEA, thatmakes, imports or distributesconstruction products for salewithin the EEA, must ensure thatif a hEN exists for that product, itis CE Marked. To market aproduct covered by a hENwithout a CE Mark is a criminaloffence.
What Does CE MarkingInvolve?Most CE Marked products canbe placed on the market subjectonly to an internal factoryproduction control (FPC) by themanufacturer. The manufacturermust carry out a conformityassessment, set up a technicalfile and sign a Declaration ofConformity. The documentationhas to be made available torelevant Authorities on request.Importers of products have toverify that the manufactureroutside the EU has undertakenthe necessary steps and that thedocumentation is available uponrequest. Importers should alsomake sure that contact with themanufacturer can always beestablished.
Distributors must be able todemonstrate to appropriateNational Authorities that theyhave acted with due care andthey must have affirmation fromthe manufacturer or importerthat the necessary compliancemeasures have been taken. Theprocess for achieving CE Markcertification consists of thefollowing stages:
1. Identify the applicable Directive(s)
2. Identify the applicable requirements of the Directive(s)
3. Identify an appropriate route to conformity
4. Assess the product’s conformity
5. Compile the technical documentation
6. Make a declaration and affix the CE Marking.
What is ‘Self-Certification’?Depending on the level of risk of the product, the CE Mark isaffixed by the manufacturer (orauthorised representative) whodecides whether the productmeets all the CE Markingrequirements. If a product hasminimal risk, it can be self-certified where manufacturerssign a Declaration of Conformityand affix the CE Mark to theirown product.
33
Certain products may also beCE Marked where no hEN exists,but a European TechnicalAssessment (ETA) for theproduct does. This involves a formal ‘Assessment andVerification of Constancy ofPerformance’ (AVoCP) for theproduct and the manufacturer. In this case, the manufacturermust have as a minimum:Factory Production Control(FPC), carried out type-testingon the product to be CE Markedand signed a Declaration of Performance (DoP).This information is submitted tothe European Organisation for Technical Approvals (EOTA) for
assessment. On completion,EOTA will issue a EuropeanAssessment Document (EAD),thereby enabling the CE Mark to be applied.
What is a ‘Notified Body’?Products considered to have a greater risk must beindependently certified by aNotified Body (NB). This is anorganisation that has beennominated by a member stateand has been notified by theEuropean Commission. TheseNotified Bodies act as test labsand/or certification bodies thatcarry out the steps as listed inthe relevant Directives and thendecide whether the product has passed.
A manufacturer can choose its own Notified Body in anymember state of the EU, but theyshould be independent of themanufacturer and a privatesector organisation or agovernment agency.
Legal ImplicationsThere are mechanisms in placeto ensure that the CE Marking is put on products correctly.Controlling products bearing CEMarking is the responsibility ofpublic Authorities in memberstates, in co-operation with theEuropean Commission.
The procedures, measures and sanctions applying tocounterfeiting of CE Marking
vary according to the respectivemember state's national
administrative and penal law.Depending on the seriousness of the crime, economicoperators may be liable to a fineand in some circumstances,imprisonment. However, if theproduct is not regarded as animminent safety risk, themanufacturer may be given anopportunity to ensure that theproduct is in conformity to theapplicable Legislation before it is obliged to take the productoff the market.
There are currently noHarmonised EuropeanStandards (hEN) for SIPS.However, the document: EN prEN 14732-2011 (Proposed Standard for TimberStructures, Prefabricated Wall,Floor and Roof Elements) is widely expected to bedeveloped into the hEN for SIPS in the future.
Cogent Consultancy Limited is a construction orientatedconsulting business, who planand deliver CE Markingcertification projects formanufacturers of buildingtechnology products throughoutthe UK.
For further information email:[email protected].
The Manufacturer Must Do Several Things:
1.Decide whether the product needs to have a CE Mark.
2.Choose the conformity assessment procedure from the modules specified by theDirective relevant to the product. There are several modules available for the conformity assessment procedure, these are:
• Module A – Internal production control.
• Module B – EC type-examination
• Module C – Conformity to type.
• Module D – Production quality assurance.
• Module E – Product quality assurance.
• Module F – Product verification.
• Module G – Unit verification.• Module H – Full quality
assurance.
These modules will often askquestions about the product to classify the level of risk andthen refer to the ‘ConformityAssessment Procedures’chart, which shows all theacceptable options availableto a manufacturer to certify theproduct and affix the CE Mark.

SIPS are one of the leading ways to construct energy efficient, cost-effective andsustainable buildings. To help everyone understand them better and know how toimplement their use correctly, the UK SIP Association has published a Code ofPractice/Pocket Guide to SIPS.
This document includes a handy summary of all the six special Technical Bulletinsthat have been commissioned in conjunction with TRADA Technology that areintended to provide introductory information on using SIPS. These Bulletins relateto: Acoustics, Durability, Fire, Structure, Sustainability and Thermal.
Acoustics – improved soundperformance levels that can bedelivered by SIP panels. SIPscontribute to improved airbornesound insulation for floors roofs,external, internal and separating/party/compartment walls. Muchlike timber studwork, SIP panelsrely on the mass and continuityof plasterboard linings to providethe majority of the soundinsulation performance.
Durability – the long termperformance of a SIPs buildingwill be largely dependent onrepair and maintenance. Duringconstruction the SIP structuremay be exposed to the prevailingweather conditions and may beexposed to rain. This is not anissue for SIPs as long as anumber of general precautionsare followed. Cladding systemscan take the form of masonrysuch as brick, rendered blockwork or stone or lightweightsystems such as timber, metal orproprietary render systems
Fire – all forms of constructionneed to comply with the fireperformance requirements laiddown by national BuildingRegulations. There is no
difficulty in SIP- basedstructures meeting the requiredlevels, given correct design,standards of manufacture andworkmanship. The fire resistanceof a SIP structure is primarilyachieved by the use of fireresistant lining materials.
Structure – all aspects of thebuilding phase from walls, floors,roofing cladding and services totolerances for walls and soleplates. There are twofundamental applications forSIPs – full structural and infill fora concrete, steel or engineeredtimber frame. In all cases theproduct will be engineered forloadbearing capability, rackingresistance and wind loading.

Sustainability – for constructionto be sustainable, the basicprinciples of sustainabledevelopment must be adopted.The UK Government's strategyfor more sustainableconstruction widens the basicthemes to suggest key actionsby the construction industry.These include designing forminimum waste, leanconstruction, minimising energyuse in construction and avoidingpollution. SIPs offer a relativelylow embodied energy buildingsystem with good long termthermal and airtightnessperformance and are also ableto offer a long design andservice life.
Thermal - ‘Fabric First’ is apopular ethos that has grownfrom the German Passivhausstandard. This is where energyefficient buildings are created by focusing on the performance of the external envelope of thebuilding before using or ‘bolt on’renewable energy technologies.With SIP structures excellent U-values can be achieved.
