Frequently Asked Questions
How is this different from the glasshouse and shade house versions?
All three share the same 1972mm x 6386mm footprint and aluminium frame, but the glazing differs: this greenhouse uses 6mm twin-wall polycarbonate for strong insulation and UV protection, the glasshouse uses 4mm toughened glass for maximum light transmission, and the shade house uses perforated aluminium mesh for 50% shade rather than full weather protection.
How long does delivery take?
Greenhouses are packed to order on a first-come-first-served basis, generally with around a 2 week lead time. Delivery is to your nearest Mainfreight Depot, as these units can only be shipped that way due to their weight.
Does polycarbonate perform better than glass in hot climates?
Twin-wall polycarbonate generally offers better insulation and more diffused light than single-pane glass, which can help moderate temperature swings. Which glazing suits you best depends on your climate and what you're growing.
