8x20 Polycarbonate Greenhouse with Twin-Wall Insulated Panels

High-Capacity 8x20 Greenhouse for All-Season Growing and Climate Control

6mm Twin-Wall Polycarbonate for Insulation and UV Protection

This 8x20ft greenhouse is built with 6mm twin-wall polycarbonate panels for reliable insulation and light diffusion. The glazing is UV-protected on both sides, helping to maintain a consistent internal climate while protecting plants from temperature extremes and sunburn.

Extra Ventilation with 8 Roof Vents and a Rust-Resistant Frame

With eight roof vents included as standard, this greenhouse delivers excellent airflow across its extended layout. The matt-black aluminium frame is powder-coated for rust resistance and built to endure Australia’s harshest conditions.

Designed in New Zealand. Assembled in Australia.

Manufactured in New Zealand and assembled locally, this glasshouse 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.
