Maximum-Length 8x24 Greenhouse for Large-Scale Growing and Year-Round Protection

6mm Twin-Wall Polycarbonate for Insulation, Light Diffusion, and UV Protection

This 8x24ft greenhouse uses 6mm premium-grade twin-wall polycarbonate panels — UV-protected on both sides for extended durability in harsh conditions. The glazing delivers consistent internal temperatures and soft, diffused light to help plants thrive year-round.

Heavy-Duty Frame with 8 Roof Vents for Superior Ventilation

The rust-resistant aluminium frame is powder-coated in matte black for long-term protection and a clean, architectural finish. Eight roof vents are included to promote optimal airflow throughout the entire greenhouse — critical in longer structures.

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.
