Key Features & Benefits
-
Ideal for Greenhouses: These sheets are a superior, shatterproof alternative to traditional horticultural glass. They provide excellent UV protection and light diffusion, creating the perfect growing environment for your plants while being significantly safer in high-traffic garden areas.
-
High Impact Resistance: Polycarbonate is virtually unbreakable, offering high-level protection against heavy rain, hail, and accidental impact—essential for the unpredictable British weather.
-
Superior Thermal Insulation: The multi-wall design traps air between the layers, helping to retain heat within your greenhouse or cold frame, which can extend your growing season through the colder UK months.
-
Lightweight & Easy to Install: Significantly lighter than glass, these sheets are easy to manoeuvre and can be cut to size using standard DIY tools without the risk of cracking or shattering.
-
UV Protected: Treated with a UV-resistant coating to prevent yellowing and brittleness over time, ensuring your glazing remains clear and effective for years to come.
Common Applications
-
Greenhouse Glazing: Replacement panels for timber or aluminium frames.
-
Cold Frames & Cloches: Protect young seedlings from frost.
-
Shed Windows: A secure and durable alternative to acrylic or glass.
-
Carports & Lean-tos: Lightweight roofing for smaller garden structures.
Pro Tip: When installing, ensure the UV-protected side faces outwards toward the sun (usually indicated by the branding on the protective film) and use appropriate sealing tapes to prevent moisture or insects from entering the flutes.
