10x20 Polycarbonate Greenhouse with Twin-Wall Insulated Panel

10x20 Greenhouse for Serious Growers Who Need Space and Thermal Efficiency

6mm Twin-Wall Polycarbonate for Insulation and Plant Protection

This 10x20ft greenhouse features 6mm twin-wall polycarbonate glazing that offers excellent thermal performance, shielding plants from frost and harsh sun. The diffused light promotes healthy growth while maintaining a more stable internal environment across all seasons.

Expansive Layout and High Roof for Efficient Workflow

With internal dimensions of 3220mm wide and 6386mm long, the structure provides ample space for propagation, plant staging, raised beds, and walkways. The tall 2850mm roofline improves airflow while allowing room for trellised crops or vertical shelving.

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.

Award-Winning Design and Rust-Proof Frame

The frame is built from powder-coated matte-black aluminium, offering exceptional durability and corrosion resistance. Combined with a streamlined modular design, it’s easy to assemble and built to last.
