Is WPC waterproof?

Do not assume so. Water uptake depends on the formulation, exposed edges and test conditions. Use the manufacturer’s permitted exposure and installation details; moisture-resistant does not mean impermeable.

faq · en

Does composite decking get hot?

A sun-exposed surface can become hot. Colour, exposure and the product affect comfort. For barefoot areas, assess samples in representative conditions rather than inferring temperature from the WPC label.

faq · en

Is WPC stronger than wood?

There is no universal answer. Compare the complete member, support arrangement, loading duration and conditions. A tensile-strength number does not determine deck-board span.

faq · en

How long does WPC last?

There is no single lifespan for all formulations and climates. Assess relevant exposure tests, documented installations, maintenance and warranty exclusions. Warranty length is not a measured service life.

faq · en

Can WPC replace structural timber?

Only where the exact product is designed and documented for that role. A decking board, decorative fascia or fence infill is not automatically a beam, load-bearing joist or protective railing.

Is WPC environmentally friendly?

Evaluate the complete life cycle and actual recovery route. Recycled content, wood content and local production can matter, but none independently proves the lowest environmental impact.

faq · en

Is WPC the same as SPC flooring?

No. In flooring catalogues, WPC and SPC may be used for different engineered core systems. Ask for the actual composition and intended indoor or outdoor use instead of transferring decking properties to a floor product.
