UV-Stabilised Panels
Polycarbonate roof panel and windows provide natural light from all angles and diffuse light better than glass for stronger, healthier growth. UV-stabilised for long-lasting use, the panels resist sun damage to keep your cold frame looking and performing its best.
Hinged Roof with Sliding Lifts
Sloped roof features drainage holes at the base, allowing rain and snow to easily drain away without pooling on top. Fitted with powder-coated steel sliding lifts and double hinges, the lid opens smoothly to any position and stays in place for easy access and ventilation.
ACQ-Treated Fir Wood
Crafted from durable, lightweight fir wood, the cold frame is easy to pick up, reposition, and move around your garden. The timber is FSC certified, meaning its sourced from responsibly managed forests that provide lasting environmental, social, and economic benefits.
Quick & Easy Assembly
Delivered flat-packed with clear instructions, the cold frame is quick and easy to assemble with all fixings included. Galvanised fittings resist rust and corrosion, while base plates with ground holes allow you to peg it down for extra stability in windy weather.
