Glazing ↓

Select From 3 Premium Glazing Options

6mm twinwall polycarbonate is the practical choice for year-round growing. It retains heat efficiently, keeping frosts out during winter while reducing heat build-up in summer. The twinwall construction provides better insulation than single-layer glazing, helping to maintain a stable growing environment.
10-Year Warranty Against Breakage and Panel Blowouts

4mm toughened safety glass delivers superior clarity and maximum light transmission, making it the premium choice for serious growers and those wanting a stunning garden feature. Manufactured to NZ safety standards, it is significantly stronger than standard glass and will not shatter into dangerous shards if broken. The timeless look of glass adds elegance and value to any property.
25-Year Glazing Warranty

Expanded aluminium shade mesh is purpose-built for plants that thrive in filtered light. Blocking approximately 50% of direct sunlight, it keeps temperatures cooler while maintaining natural airflow throughout the structure. Perfect for light-sensitive plants such as orchids, azaleas and ferns, and ideal for hardening off young seedlings before moving them outdoors.

1-Tier Shelving – A single-level staging shelf, handy as a lower potting bench or seedling surface.

Shelving Brackets – Cost-effective bracket pairs (150, 300, and 450mm depths) for building your own shelving along the walls.
Hanging Brackets – Sold in packs of six, for string lines or hanging pots and baskets overhead.

Accessories

Fit out your 6×20 with practical add-ons for ventilation, sun protection, and a secure footing.

Auto Vent Openers – Non-electric openers that open the roof vents automatically as it heats up and close them as it cools. This model has 8 roof vents (glass and polycarbonate versions).
Louvre Vent Kit – Side-wall louvre windows that let cool air in low while warm air escapes through the roof. Choose the kit to match your glazing.
Shade Cover Kit – Removable 70% shade cover on an aluminium frame that keeps plants from overheating in summer. Made to size for larger houses, so ask our team for the right fit for the 6×20.
Mounting Kit – As a 16ft-plus house, this size already includes L-shaped surface-mounting brackets and corner stakes for fixing to timber or concrete, so no separate foundation kit is needed.
Mesh Screen Door – Lets you leave the doorway open for extra airflow while keeping insects out. A top door extension is also available for 6ft-wide models.
