BEST POLYCARBONATE GREENHOUSES: TOP PICKS FOR DURABILITY - SAKSBY.com

Polycarbonate greenhouses offer gardeners a superb equilibrium between durability, light diffusion, and heat retention, making them a popular choice in a variety of climates. Unlike glass, polycarbonate is less prone to breakage and boasts excellent insulation properties, which is vital for extending the growing season. Gardeners also favor these structures due to their resistance to UV rays and strong weather conditions, protecting plants year-round.


When considering a polycarbonate greenhouse, key purchasing considerations revolve around size, frame material, and polycarbonate thickness. Size should be determined by the space available and the intended use, whether for a small urban garden or a large vegetable crop. The frame material, typically aluminum or galvanized steel, needs to provide sturdy support and resist the elements. The thickness of the polycarbonate panels affects both the durability and insulation, with thicker panels generally providing better performance.

Buying Guide

Frame Material

We consider the frame material as it determines the structure's durability and stability. Aluminum is a popular choice due to its lightweight and resistance to rust.


Material Pros Cons
Aluminum Lightweight, Rustproof Less Insulating
Steel Strong, Sturdy Can Rust, Heavier

Glazing Options

For the glazing, we evaluate both twin-wall and single-wall polycarbonate panels. Twin-wall panels provide better insulation but are generally more expensive.


Type Insulation Durability Cost
Single-Wall Lower Moderate Low
Twin-Wall Higher High High

Size and Shape

We assess the available space in our garden and consider the greenhouse's size and shape. A larger greenhouse allows for more plants but requires more maintenance.


Features to Consider:


  • Ventilation: Adequate roof vents and side vents for air circulation.
  • Guttering: Integrated gutters for rainwater collection.
  • Door Type: Hinged or sliding doors for easy accessibility.

When looking for the best polycarbonate greenhouse, we review these critical features. We emphasize quality construction, appropriate size, and functional extras that align with our gardening needs.
