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 Security Shed is built for the things you would rather nobody could see. There is no glazing at all — solid composite cladding on every wall — so bikes, tools and machinery stay out of sight. Matte black hinges and a black slide bolt keep the door line clean and discreet. The zero-maintenance WPC composite cladding never needs painting, staining or treating, anthracite grey fascia, corner trims and joining strips run around the building, and a high-performance EPDM rubber roof keeps everything dry. Pre-assembled modular panels install in a day, backed 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.
