Do Polycarbonate Greenhouses Stay Warm in Winter? A Smart Choice for New Zealand Gardeners

As winter approaches in New Zealand, especially in regions like Auckland, where temperatures can drop and sunlight hours are reduced, choosing the right greenhouse material becomes critical for year-round gardening. One of today's most popular and practical choices is the polycarbonate greenhouse — but does it stay warm in winter?


Twin-Wall Polycarbonate: Built for Thermal Insulation

Most polycarbonate greenhouses are made using twin-wall polycarbonate panels. These panels feature a layered structure that traps air pockets between the sheets. This trapped air acts as an insulating barrier, slowing down heat loss significantly compared to traditional single-pane glass.

This makes polycarbonate greenhouses highly effective at retaining heat overnight and during cold spells, helping your plants stay protected even in New Zealand's chilly winter months.


Even Heat Distribution – No Hot Spots

Another significant advantage of polycarbonate is its ability to diffuse sunlight. Polycarbonate scatters light evenly throughout the greenhouse's interior rather than allowing direct sunlight to create hot spots. This ensures consistent warmth and light distribution, which is especially important in the winter when every bit of sunshine counts.


Durable and Weather-Resistant

New Zealand winters can bring strong winds and occasional snow, particularly in the South Island or elevated areas. Polycarbonate is lightweight, making it easy to install and incredibly impact-resistant. It protects against snow loads, hail, and gusty conditions, making it a practical and reliable choice for Kiwi gardeners.


Ideal for Auckland and Beyond

Whether gardening in Auckland's mild winters or facing cooler temperatures further south, a polycarbonate greenhouse can help you extend your growing season and protect your plants all year round.
