UV rating & colour fading
Straight answer: all composite fades a little — the quality of the cladding decides how much. Ours is UV-rated to hold its colour within 10% over 10 years, because the UV stabilisers are mixed through the board when it's made — not a coating that sunlight can wear off.
Cheaper boards skip or skimp the stabiliser package — that's the chalky, grey-washed composite you may have seen. Colour-through material plus the stabiliser mix is why ours also carries a 30-year manufacturer warranty.
We'll be at Glee — Birmingham NEC, 8–10 September 2026, stand 19B40-C41. It's a trade show, but you're very welcome if you'd like to buy a ticket and visit us.
UK manufactured in our own workshops, the Composite Pent Full Height Summer House puts floor-to-eaves glazing across the front so the garden becomes part of the room. Behind it, zero-maintenance WPC composite cladding means no painting, staining or annual treatment, while anthracite grey fascia, corner trims and joining strips give the building a clean architectural edge. A high-performance EPDM rubber roof protects it through every British season. Pre-assembled modular panels make for a one-day installation, and the building is covered by a 30-year warranty.

Sizes are nominal footprints in feet. External dimensions can differ slightly from the headline size because of cladding overhang and panel construction — the internal heights listed are the real usable measurements.
