THINK YOU KNOW EVERYTHING ABOUT COMPOSITE DECKING ?
Sourcing for your next decking project ?
Look for the Mark
Many members of the Timber Decking & Cladding Association ( TDCA ) supply wooden deck components , independently verified under the DeckMark quality scheme . Several supply or manufacture wood plastic / polymer composite ( wpc ) products too – yet independently accredited products are rare .
The TDCA takes a closer look at this popular product : an alternative to natural timber ?

Tite-Fix : DeckMark Approved fixings
Wpc boards are manufactured using a mixture of wood fibre , plastic and other additives – finely ground , mixed and made molten then extruded through an aperture plate to produce desired sizes and profiles . They are manufactured to individual formulas with varying percentages of timber content . This means quality will differ from product to product .
Some differences between wpc and timber
Wpc is marketed on its durability ( long life , rot resistance ) and low maintenance – although all outdoor surfaces require basic cleaning routines to avoid build-up of algae and moss . Unlike timber , recycling composite products at the end of life is currently very limited . Relatively heavy wpc is generally not as strong as timber , so it ’ s likely that deck substructure joists will need spacing closer together to provide adequate support . Wpc decking tends to expand along the length of the board so appropriate expansion gaps are required between abutting boards and adjacent surfaces . Specialist fixings are used with wpc deck products , particularly ‘ secret ’ fixings , clips and coloured trim fixings .
Many manufacturers offer long service life warranties - valid only if the product is installed to their exact instructions . Make sure you ask about performance data and keep all records and receipts of purchase and installation .
