About composites

  • 1. What are Teckwood's composite cladding and decking boards made from?

    Teckwood have created an environmentally friendly engineered wood plastic composite (WPC) material made from 100% FSC® certified timber and 40% recycled high density polyethylene plastic. Other materials include UV stabilizer, colouring and anti-fungal agents.

  • 2. What finishes are available?

    Teckwood’s wood plastic composite cladding boards are finished with an enhanced woodgrain effect

    Teckwood’s wood plastic composite decking boards are dual sided. Finished with a castellated anti-slip surface on one side and an enhanced grain on the reverse.

  • 3. What is the difference between composites and timber?

    Traditional timber expands as it absorbs water, it may also rot over time as well as requiring a high level of maintenance. Teckwood’s wood plastic composite cladding and decking will not rot and is very low maintenance. Our decking also has greater slip and UV resistance than traditional timber decking.


  • 4. Do Teckwood's composites carry a fire rating?

    Our cladding products have a much higher ignition rate than standard timber. Its self-ignition temperature is 450°C/840°F, thus it is less likely to catch fire. Our wood plastic composite cladding carries a fire class specification of B-s2,d0.


  • 5. Will the colour of my composite change over time?

    Our wood plastic composites are made in batches, slight colour variations may occur. We use FSC® certified timber in making a natural product and once any colour bleaching has taken place, usually about 10% in the first 3 months, the UV stabiliser keeps the colour looking rich and vibrant.


  • 6. What is the warranty?

  • 7. How do composites react to temperature change?

    Wood plastic components are designed to expand and contract to atmospheric conditions. The concealed stainless steel fixing clips allow the physical effects to go unnoticed.

  • 8. Are wood plastic composites resistant to water?

    Teckwood’s cladding and decking is made from FSC® certified timber and recycled plastics, the water absorption is far less than traditional timber. They perform exceptionally well in marine environments.


  • 9. Is composite decking slippery when wet?

    Wood plastic composite decking is renowned for its anti-slip properties, Teckwood’s decking is proven to provide a great anti-slip surface, tested by SGS and Intertek.

  • 10. Is Teckwood's composite decking child friendly?

    Yes, all our fixings are concealed, the decking does not splinter making it bare foot, child and pet friendly. It has excellent anti-slip properties.

  • 11. Can I paint or stain my composite?

    No we do not recommend it. Teckwood’s wood plastic composites do not require any traditional timber treatment for protection as it is highly resistant to rotting, splintering and decay.


  • 12. How do I clean my composite?

    Teckwood’s composites are very low maintenance. Soapy water can used to quickly clean away debris. If you choose to use a power washer please keep at least a distance of 30cm between the power jet and the surface.

Installating composites

  • 13. Do I need any special tools for installation?

    There are no special tools required when cutting the composite cladding or decking. We would however recommend cutting the cladding using a TCT saw blade.

  • 14. What span should I use between the joists?

    Cladding -Teckwood  recommend a 500mm maximum span between the centres of the joists. Our installation manual can be viewed here

    Decking – Teckwood recommend a 300mm maximum span between the centres of the joists. Our installation manual can be viewed here

  • 15. Can I extend the composite beyond the joist?

    Yes, our composite cladding and decking can cantilever a maximum of 20mm past the end of the joist.

  • 16. Can I glue my composite in place?

    We do not recommend using any type of adhesive to install Teckwood’s wood plastic composite cladding or decking.

  • 17. Do I have to leave a gap when butting boards end to end?

    You should always install your composite  in accordance with the manufacturer’s manual to allow for thermal expansion and contraction.

  • 18. Do you recommend any special fasteners for the decking?

    Yes, to ensure that all our decking is barefoot friendly we recommend that use you our black electro plated stainless steel concealed clips. Please see our installation manual for details.

  • 19. Can I use Teckwood's composite joist for load bearing applications?

    We do not recommend composite joists for load bearing as it has not been tested. Please consult our team or a structural engineer if you have any further questions.

  • 20. Why do stainless steel clips look as though they are rusting?

    What may appear to be rust is actually surface corrosion. When stainless steel comes in contact with chloride (which is found in seawater) or chlorine (which is used in swimming pools), the protective chromium oxide layer gets penetrated and allows a corrosive attack to occur. Thoroughly rinsing all your deck with fresh water after it is exposed to salt or chlorinated water is the best way to prevent corrosion.
