Transform your garden or allotment into a productive growing space all year round with this robust 4 x 3m polytunnel greenhouse. Built around a galvanised steel frame reinforced with four additional roof brace bars and clad in 140 g/m2 UV6-coated PE sheeting, it offers a weatherproof, light-filled environment for vegetables, seedlings, and tender plants season after season. Two people or more are recommended for assembly.
Features:- Wind-tested galvanised steel frame uses 25 mm and 19 mm tubing plus four extra roof brace bars, rated to withstand level 6 winds when anchored correctly - giving you confidence it will stay put through a British winter.
- Two solid steel hinged doors with latch-and-catch closures provide a wide, reliable entry on both ends, making it easy to wheel in barrows, carry trays, and move tall plants without having to stoop or struggle.
- Eight 35 x 35 cm mesh-lined side windows with roll-up covers and tie straps let you dial in exactly the ventilation you need, keeping warmth in and insects out while preventing excess humidity from building up.
- 140 g/m2 reinforced PE sheeting with UV6 coating resists sun degradation and ageing, maintaining healthy light transmission for your plants across multiple growing seasons without yellowing or cracking.
- A 20 cm soil flap runs around the base of the cover so you can bury the edge into the ground, sealing out draughts and improving stability - and the whole structure still dismantles for relocation or off-season storage.
