Is WPC good for exterior walls?

Capped WPC is made for weather, and Alfresco is catalogued for protected exterior walls and low-rise residential facades. Exposure and fire rules decide each project.

Is WPC termite-proof?

WPC resists termites and borers far better than plain timber because the fibres are bound in polymer.

Can fluted panels be used for a TV wall?

Yes, fluted cladding is a common feature wall behind a TV. Plan cable routes before the sub-frame goes up.

All exterior materials weather. Capping slows it; shaded and protected walls fade least.

WPC fluted panels vs PVC panels vs real wood cladding

By the GM La Surfaces team · Updated 3 October 2026

Short answer

WPC (wood-plastic composite) mixes wood fibre with a polymer, so it looks warmer than PVC and resists rot and borers better than plain timber. PVC panels are lighter and cheaper but read as plastic. Real wood is the most natural and needs the most care. None of them is non-combustible.

What is WPC?

Wood fibre bound in a thermoplastic. Capped WPC adds a protective polymer layer over the surface. Alfresco cladding, for example, is natural timber fibre and recycled polymer under a polymer cap, in fluted profiles.

WPC vs PVC vs wood

Look: wood is the real thing; WPC has a warm, wood-like grain; PVC is smoother and more uniform.
Moisture: PVC does not absorb water; WPC resists it far better than timber; untreated wood needs sealing.
Termites and rot: WPC and PVC resist them; wood needs treatment.
Sun: all of them weather. Polymers age under UV and wood greys. Capped profiles and protected walls last best.

Installation

Fluted cladding goes onto a sub-frame rather than straight onto the wall. Alfresco is fixed on an aluminium sub-frame at 400 mm centres, with pre-drilled holes and a 5 mm gap at butt joints so the boards can expand.

Fire

WPC is combustible and Alfresco carries no fire rating. On any facade where fire rules apply, check local code first; GM La Surfaces does not claim compliance for a regulated facade.
