This RS PRO sheet is ideal to use as waterproofing or for insulation. It's made of ethylene propylene diene monomer (EPDM) rubber, which is a durable and weather-resistant material suited for use at home or in industrial settings.
EPDM has excellent resistance to oxidation and ultraviolet (UV) rays, so it won't crack or discolour over time. It's also waterproof and breathable, allowing moisture to escape and so preventing mould build-up.
The product is Water Regulations Advisory Scheme (WRAS) tested and approved, meaning it's suitable for carrying or receiving water from the UK public mains supply. You can use this sheeting in industrial environments for insulating electrical cables or making seals as it tolerates high temperatures.
