10 x 12 ft Greenhouse with Thermal Control and Robust Construction for Harsh Conditions

6mm Twin-Wall Polycarbonate for All-Season Insulation

This 10x12ft greenhouse is fitted with 6mm premium-grade twin-wall polycarbonate panels that provide excellent insulation and diffused natural light. UV-protected on both sides, the glazing helps maintain stable internal conditions for plants all year round — shielding them from both frost and extreme sun.

Wider Frame and Elevated Roofline for Flexible Growing

At 3220mm wide and 2850mm high to the ridge, this model offers generous space for vertical growing, trellises, or large shelving systems. The matt-black aluminium frame is powder-coated to resist rust and withstand the rigours of the Australian climate.

Designed in New Zealand. Assembled in Australia.

Manufactured in New Zealand and assembled locally, this greenhouse is purpose-built for Australian conditions. Unlike many imported kits designed for milder climates, Winter Gardenz structures are engineered to handle the extreme weather seen in regional and coastal Australia — from strong winds to temperature swings.
