6x12 Polycarbonate Greenhouse with Twin-Wall Insulated Panels

Large 6x12 Greenhouse with Superior Thermal Control for Australian Conditions

6mm Twin-Wall Polycarbonate for Year-Round Insulation

This 6x12ft greenhouse is built with 6mm premium-grade twin-wall polycarbonate — a high-performing material that insulates better than glass. It helps reduce heat loss in winter and prevents overheating in summer, keeping your plants protected across all seasons.

Matt-Black Powder-Coated Frame for Structural Integrity

The aluminium frame is powder-coated for rust resistance and long-term durability. Designed to support the full 12ft span, it delivers strength and rigidity while maintaining a clean, modern look suitable for any garden or backyard.
