The 10' x 20' Palram Canopia Balance Silver Large Greenhouse (3.04m x 6.04m) is a robust, high-specification polycarbonate greenhouse with a user-friendly design, which combine to make it an absolute gardener's dream glasshouse.A High-Spec GreenhouseSupported by a silver aluminium frame, for added strength and an extra-rigid structure, this large greenhouse uses both light-diffusing 4mm twin-wall polycarbonate roof panels and crystal-clear polycarbonate side panels, the latter of which provide 90% light transmission. Both types of polycarbonate panel are completely UV-protected.The roof panels promote an even temperature by increasing thermal insulation and reducing extreme sunlight exposure, so plants enjoy perfect growing conditions, the gardener remains safe from harmful UV-rays, and the panels neither discolour nor fade in the sun. The roof's apex style gives this greenhouse a traditional feel and ensures highly effective rainwater runoff.Great Weatherproof ProtectionShatterproof, fracture-proof and completely resistant to rust, this polycarbonate greenhouse uses the latest Fine Shield Technology™. It is wind resistant to 90km/ hr (56ml/ hr) and snow-load tested to 75kg/ m² (15.4lbs/ ft²), so provides both plants and garden equipment with outstanding weatherproof protection.DoorsUser-friendly access is gained through wide double doors, which feature aluminium hinges, a low threshold, magnetic catch and padlock fixing, so valuable tools remain safe from unwanted attention (padlock not included).Other Key FeaturesThis polycarbonate greenhouse includes integrated guttering too, offering a free and sustainable supply of water for plants. Six manually-opened roof vents allow the temperature to be regulated for the benefit of plants and gardeners alike.Warranty and AssemblySupplied with a reassuring 5-year limited warranty and completely maintenance free, this large greenhouse's high-impact polycarbonate panels are pre-cut with uniform profiles, allowing them to be slid into place for an incredibly easy assembly.
