Is WPC cladding automatically fire compliant?
No. A material name is not compliance evidence. The applicable requirements and assembly need a project-specific review.

Can decking profiles be used as fencing?
Only when the proposed use and connections are supported by suitable product and design information.

Are solid boards always stronger than hollow boards?
Geometry alone is insufficient. Use profile-specific evidence for loading, supports and exposure.

Can every composite board span 600 mm?
No universal spacing follows from the material name. Use the permitted spacing for the exact product and project.

Does capped WPC need no maintenance?
Capping does not remove the need for product-specific cleaning and installation instructions.

Can uncapped-profile tests cover a capped profile?
Do not assume they do. Ask whether the evidence covers the current construction.

Is WPC waterproof?
Do not apply that claim to the whole family. Moisture behaviour depends on formulation and construction.

Does a long warranty prove service life?
A warranty is a contractual promise with conditions. It does not replace a performance assessment.

Does natural fibre mean biodegradable composite?
No. An ingredient of natural origin does not establish biodegradability of the whole fibre–polymer product.

Can one plant fibre replace another directly?
Do not assume direct substitution. Validate the supplied fibre, processing behaviour and finished component.

Is WPC a type of NFC?
In the broad material-family sense, wood-fibre polymer composites fit within natural-fibre composites. Documents may define the terms differently.
2026-09-24Read reference ↗
Does NFC mean plastic-free?
No. NFC describes the natural fibre component, not the absence of a polymer matrix.

Is recycled polymer always lower quality?
A recycled-content label alone is not a performance result. Compare feedstock controls and finished-product evidence.
2026-09-24Read reference ↗
Can I compare boards by polymer alone?
No. Fibre, additives, geometry, processing and exposure also affect the comparison.

Can WPC go in household plastic recycling?
Do not assume acceptance. Ask the local operator or take-back provider about the exact material.
2026-09-24Read reference ↗
Does natural fibre make a composite compostable?
No. Compostability needs evidence for the entire product under specified conditions.

Does “tested to EN 15534” mean the product passed?
That phrase is incomplete. Ask which part, edition, properties and requirements were assessed, and request the results.

Is a report valid in every country?
Not automatically. Consider the scope of the report together with the requirements of the destination project.
2026-09-24Read reference ↗
Is WPC the same as solid wood?
No. WPC combines wood-derived material with polymer and needs its own product documentation.
2026-09-24Read reference ↗
Is every WPC product PVC-free?
No. The polymer must be identified; the term WPC does not establish that PVC is absent.
