An ideal solutionTimber cladding is being specified today more and more by local authorities, architects and developersfor its environmental credentials and for its ease ofworking, natural beauty, performance andcompetitive price.

Timber is one building material that has an unrivalledpedigree for use in construction, which is why timber is an ideal choice for use as an external cladding.

Working with some of Europe’s leadingmanufacturers ArborClad has selected a range ofproducts at the forefront of design and technology to meet today’s challenging cladding requirements.

Standard profilesTraditional cladding styles and patterns are always going to be in Vogue. For this reason our standard stock range is based on the popular shiplap andoffset cladding profiles. It is also why the moretraditional Redwood, Larch and Western Red Cedarspecies are included.

These are timber species with a proven performance and appearance and, alongside the other products in the range, ensure the perfect solution for any installation is available.

Domestic, commercial and refurbishmentIdeal for commercial, domestic and refurbishmentprojects, ArborClad cladding range offers a perfectstarting point from where you can select thematerials most suited to each individual project. The longer a building product lasts the better it is for the environment, especially a critical externalenvelope component such as cladding.

Bespoke profiles*We deal with timber on a daily basis, so we know its limitations. We also know that you occasionally want to be different and stand out from the crowd!

At ArborClad we employ skilled woodworkingmachinists who are able to produce a full range of bespoke profiles to suit even the most demandingof specifications. These bespoke items can beproduced, in addition to the timbers featured in thestandard cladding range, from a wide variety ofother timber species - Green Oak, Sweet Chestnut,Douglas Fir, Cumaru to name a few.

With improved stability and durabilityqualities, thermally treated claddingprovides added long term benefitsand flexibility.Through the treatment applied, the timber is less prone to absorb or losemoisture, helping to restrict the potential for swelling, shrinkage or distortion.

During the thermal treatment process, the wood also acquires a beautifulbrown colour and its velvet-like surface is pleasant to the touch. At its best, thewood possesses nuances of antique and fine wood shades that bring warmthto any project, be this for an internal or external application.

The thermal treatment processHeat treatment (within a range of 160ºC to 215ºC)has the effect of modifying the properties of wood. Thethermal treatment process consists of heating wood totemperatures exceeding its spontaneous combustiontemperature with the water vapour present having aprotective function. A natural process, the varyingtemperatures, varying treatment duration and varyingdrying techniques require no chemical additives andimpart new properties to the treated wood.

Through the treatment applied, the timber is lessprone to absorb or lose moisture, helping to restrictthe potential for swelling, shrinkage or distortion.

During the thermal treatment process, the wood alsoacquires a beautiful brown colour and its velvet-likesurface is pleasant to the touch. At its best, the woodpossesses nuances of antique and fine wood shadesthat bring warmth to any project, be this for aninternal or external application.

Leading suppliersArborClad has chosen to work with the world’s leadingsuppliers of thermally treated timbers. ArborCladThermo-D Redwood undergoes the traditional heattreatment cycle which the Finnish ThermowoodAssociation has developed, approved and promotedsince their formation in 1985.

A Thermo-S cycle of heat treatment is available, but this is only for products which are to be used in internalapplications, such as flooring. The Thermo-S treatmentis a shorter process and provides a lighter colour. Due to the limitations of use the process is likely to be gradually phased out.

Additionally, we are happy to offer to our customersArborClad Thermo-D Platowood Spruce andHardwood. Platowood, of Holland, are one of theworld’s innovators in heat treatment of wood and have a unique pedigree of supply into today’s claddingmarket. The Platowood heat treatment process is alonger treatment which, in the case of the spruce,actually enhances the timber durability.

Focusing on the environmentThe ArborClad cladding range has been selectedusing timbers sourced only from well managed andsustainable forests to ensure that a full Chain ofCustody certification can be achieved. As one of thefounder members of the Forests Forever initiative and supporters of wood for good, we feel it is ourresponsibility to provide environmental solutions forthe timber cladding market today.

Computer-controlled cuttingmachines allow precision profiling in manufacture,providing a truly bespoke service. Traditional designsthrough to more elaborate requirements are catered for byour team, who provide a timber cladding solution that notonly meets your needs but those of your building.

Timber is a natural product. Its hygroscopic propertiesmean that, through changes in moisture and humidity,timber cladding may move and, regardless of type orspecies, over time turn a silver grey colour through naturaloxidation.

It can, unless naturally durable or pre-treated, be subject tomould or insect attack. For this reason it is important, whenchoosing your cladding, that consideration be given to thelocation, species, treatment and surface finish you require.ArborClad work with leading manufacturers who provide acomprehensive range of timber preservatives, fire andfinishing systems to ensure that your cladding will lookgood for longer.

Fire protection is a crucial consideration for modern buildingsof today along with development and refurbishment ofexisting structures. Where Building Regulations require fireperformance in accordance with British Standards (TypicallyClass 0 or Class 1) or Euroclass B or C, ArborCladrecommends, and can provide, pre-treatment with a qualityassured flame retardant applied by a processor approved bythe product manufacturer. Available for both internal orexternal use and, if required, complete with a wide range ofsupplier finishing applications (paints/stains etc) ArborCladcan provide the complete solution for today’s high demands.

NB - Designers should satisfy themselves that the description of theperformance achieved in fire test ‘classification reports’ corresponds withthe species and size of cladding that they plan to specify.

With one of the most comprehensive ranges of timber cladding available on theUK market today, ArborClad timber cladding can help transform a project from‘everyday’ into a dramatic design statement.

From concept to completion, we work regularly with architects, local builders,renovators, major contractors and national house builders to ensure that theproduct specified is the right product for the right situation and at the right price.

Commercial cladding

The ArborClad timber cladding range is an idealsolution where cost and longevity are key drivers to specification.

Building designers, timber frame manufacturers andspecifiers are choosing timber cladding for its inherentqualities and its suitability for use in panel sections andoff-site modular construction.

Utilising off-site manufacturing techniques and the latestdesign technology, panels are able to be transported tosite ready for erection, saving both time and associatedconstruction costs. The advantage of producing panelsin a controlled environment mean that additional qualitycontrol checks can be made and accuracy and quality ofinstallation enhanced before the product has left thefactory gate.

Timber cladding, in particular when used with timberframe construction, provides a durable and lightweightfinishing option. The result being that the buildingexterior appears warm, fresh and clean in appearancewhilst also benefiting from additional thermal andacoustic performance.

The commercial cladding projects shown on this page, sited in both Wales and Doncaster, utilised over 500m2 of ArborClad Traditional Larch cladding,creating a highly durable and resilient exterior.

Timber is a natural product and providing it is treated in accordance with the manufacturersrecommendations it will remain looking good and will last a lifetime. The following installation guidelines are additional areas you may wish to consider when selecting and fitting your external cladding. For further information please refer to the manufacturers recommendations.

Installation guidelines

• It’s preferable to use stainless steel nails for all speciesbut especially those with a high tannin content, andthey are essential for timbers installed ‘green’. By usingStainless Steel this avoids permanent staining due to thereaction of the tannin on mild steel or galvanised nails.

• If using battens*, we recommend a minimum size of 38mm x 50mm (finished size).

HardwoodStainless steel screws/annular ring shank nails are the preferredmethod of fixing for hardwood boards. Stainless steel screwsare preferable, and essential for timbers installed ‘green’:

• Slight over-drilling of the screw holes will allow for any movement in the wood and prevent splits.Countersinking screws is also recommended.

• Where ‘green’ wood is used, it may be necessary to fit washers to the screws to maintain the fixingsecurity. This can become a design feature.

• Metal clips, which also provide a ‘secret fix’ effect, mayalso be considered. Screw fixings should be minimum40mm or half the width of the board, whichever is thegreat, from the end of the boards to avoid splitting.

Fixing external cladding

SoftwoodStainless steel annular ring shank/round head nailsare appropriate for fixing softwood cladding:

• The nail length is generally minimum 50mm or 2.5times the thickness of the board being fixed whicheveris the greater and should be punched slightly belowthe wood’s surface.

• Boards over 100mm wide should have double fixings.

• Make sure that butt joints always meet on sufficient batten support width (see below).

Board sizesHorizontal boards:

• Shiplap or feather edge type boards should have a minimum of 10mm overlap, but allow 2mm gapsbetween the upstands for movement in the timber.

• Tongued and grooved boards should have amaximum face width of 150mm, with a 2mmclearance above the tongue for expansion. Most commercially produced profiles will include these tolerances. Install with the tongue upwards.

• Open joint boards should have an 8-15mm gap at the ‘water face’. Chamfered edges allow the boards to overlap slightly, reducing any exposure of the cavity.

Vertical boards:• The face width of vertical boards should not exceed

150mm. The most versatile fixing method is board onboard. Any overlap should be a minimum of 20mm.

Diagonal boards:• Should be fixed on battens, as for vertical boards,

taking into consideration the comments above foroverlaps or tongue and groove styles.

Using battensNOTE: We recommend a minimum batten* size of 38mm x 50mm (finished size).

Use battens that are preservative treated and structurallygraded to ensure they are able to carry the weight of theboard material. Fix horizontal boards to vertical battens,taking care where boards are jointed to ensure they sitsecurely on sufficient batten width. Conversely, fix verticalboards to horizontal battens, with vertical ‘counter’battens to facilitate drainage and ventilation. Supportbattens should be fixed at spacings of no more than600mm, whether vertical or horizontal. And at no morethan 400mm for diagonal boards.

These spacings will maintain the overall stability of the cladding.

Remember the cavityThe timber cladding you are fixing to the building is effectively an outer layer of protection against the elements. However, a cavity should be formed behind the cladding to allow any water or moisture that might penetrate the cladding to escape. This ensures internal and external surfaces of the wood maintain a similar moisture content, reducing the potential for movement and distortion, allowingventilation between the inner and outer surfaces.

The cavity should be at least 19mm wide, but may be wider, depending on the thickness of fixing battens. A weatherproof membrane is usually required to protect the structure, although this may not be needed on masonry. Additionally, if not sealed a fly screemembrane should also be used to prevent insectinfiltration.

Window and door openingsOpenings within a wall require special attention to avoid the need to notch or split the boards. These openings need to be dimensionally compatiblewith the cladding to provide a good appearance aswell as allowing for fixings. Thought also needs to be given to the 3-dimensional relationship of anyflashings, sills etc. to allow for adequate drainage of water from the cladding surface and board ends.

Corner detailsThis is an important area of fixing detail, not justaesthetically but functionally, to ensure adequateprotection against water.

Mitring boards at corners is not recommended for pre-finished products, as natural movement of thetimber will allow the joint to open, causing failure of the surface coating and water ingress.

Mitring the ends of boards can be considered, but it is advisable to provide a gap between any adjoiningsurfaces and pre-finishing/treating all exposed ends.

Internal and external corners are more easily detailedon vertical boarding. These can be jointed by ‘tonguingand grooving’ to give added stability and protection.
