SuperCove is proudly manufactured in Northamptonshire, UK, using responsibly sourced, FSC® certified materials. Local production means we maintain strict quality control, ensure reliable supply, and reduce the environmental impact of long-distance shipping.
Every length is designed to deliver the strength, finish, and reliability that comes with being British-made.
Traditional plaster coving is heavy, messy, and best left to two professionals. Polystyrene may be light, but it is fragile, easily damaged, and unsafe near heat. SuperCove strikes the perfect balance. Its tough polyurethane core makes it far stronger than foam alternatives, yet light enough for one person to install with ease.
A 6 × 3 m pack weighs just 2.4 kg, compared with plaster at around 28 kg for the same coverage. That weight difference makes installation faster, cleaner, and far less tiring. SuperCove saves you time, reduces waste, and delivers a professional result without the hassle.
SuperCove is designed to work for everyone, from first-time DIYers to experienced tradespeople. It installs like plaster but without the extra adhesive, pinning, or mess. Once painted, the crisp edges and smooth finish are indistinguishable from traditional coving, giving a professional look every time.
Why people choose SuperCove:
DIYers enjoy a product that’s simple to cut, handle, and paint
Tradespeople save time with lighter, cleaner lengths and fewer breakages
Both achieve sharp, plaster-like finishes without compromise
