Polycarbonate Greenhouses

Our range of polycarbonate greenhouses is built for Australian growers who need a reliable structure that holds up to real weather — not just light showers. Designed for backyard food growers, hobbyists, and serious gardeners, these greenhouses use twin-wall insulated panels to trap heat and protect plants year-round.

Polycarbonate Greenhouses with Twin-Wall Insulated Panels

Better Insulation, More Stability

Twin-wall polycarbonate panels provide superior insulation and diffuse light evenly across your plants. They’re UV-resistant, offer added strength, and outperform glass in heat retention — perfect for colder regions or growers chasing longer seasons.

Strong Frames for Harsh Conditions

These greenhouses use sturdy aluminium or steel frames engineered to handle wind, rain, and seasonal changes. Many sizes are available to suit compact urban yards or larger garden blocks, from 6x6ft all the way up to 10x20ft and beyond.

Sizes for Every Growing Setup

Whether you’re propagating seedlings, growing crops year-round, or overwintering your collection, there's a model to suit. Choose from popular sizes like 6x8, 8x12, and 10x16 — each with full panel coverage, built-in ventilation, and secure access doors.

Easy Access and Ventilation

Most models include roof vents or side windows to help regulate temperature and airflow. Wide doors ensure you can comfortably walk in and out, even with a trolley or armful of gear.

Flat-Packed for Delivery Across Australia

All polycarbonate greenhouses are shipped flat-packed with detailed assembly instructions.
