With its classical appearance and intelligent, user-friendly features, this extra-large polycarbonate greenhouse is every gardener's dream.Utilising the very latest Fine Shield Technology™, this 8x20 greenhouse is expertly constructed from 4mm twin-wall polycarbonate roof panels and 0.7mm crystal-clear polycarbonate side panels, supported by a rust-resistant aluminium frame and extra beams for added strength.The light-diffusing roof panels promote an even temperature by increasing thermal insulation and reducing extreme sunlight exposure. Both roof and side panels are completely UV-protected and shatterproof, and together they allow 82% light transmission.
