GRP Rooflights & Translucent Roof Sheets | Colour Clad UK

GRP rooflights (Glass Reinforced Plastic translucent sheets) are the perfect solution to brighten up dark interiors in garages, barns, warehouses, and industrial units. These fibreglass roofing panels install in-plane with your metal or fibre-cement roof sheets, acting as skylights that flood your building with free natural light. With up to 85–90% light transmission, a GRP rooflight can dramatically reduce the need for electric lighting – potentially saving you up to 30–40% on energy costs during daylight hours. Plus, they diffuse sunlight to illuminate evenly without harsh glare or "hot spots," creating a safer and more comfortable environment for work or livestock.

Why Choose Our GRP Roof Light Sheets?

• Brighten Your Space & Save Energy: Let in high levels of daylight while filtering out UV. Ideal for workshops, stables, and sheds.
• Durable & Weather-Resistant: UV-stabilised to resist yellowing, with excellent impact resistance for rain, hail, and wind.
• Lightweight & Easy to Install: Easy to carry and install using standard sheet fixings. DIY-friendly, but strong enough for trade use.
• Low Maintenance: Rot-proof, rust-free and easy to clean.
• Fire Ratings Available: Supplied as standard Class 3 fire rated, with higher spec options available on request.
