Professional growers, nurseries, schools, businesses and home gardeners alike choose polycarbonate over other glazing materials for its durability, performance, and ease of use.
Polycarbonate is the strongest and most impact-resistant greenhouse glazing option available. At 200 times the strength of glass, it is virtually unbreakable, making it ideal for replacing shattered or worn-out panels. Unlike glass, which weakens and needs replacing over time, polycarbonate has an impressive lifespan of up to 20 years, providing a long-lasting, low-maintenance solution for your greenhouse. Make an investment in glazing that will last for many years to come.
Our polycarbonate sheets block 99% of harmful UV rays, offering full protection against sun damage that can harm delicate plants. While traditional glass can allow harsh glare and intense direct sunlight, polycarbonate ensures even light diffusion, preventing hot spots and creating a balanced growing environment. This helps plants thrive in ideal growing conditions without the risk of overheating or uneven exposure.
The cellular structure of polycarbonate provides excellent thermal insulation, helping to regulate temperatures inside the greenhouse. This means better heat retention during cooler months and reduced overheating in the summer, maintaining a consistent and controlled climate to support plant growth year-round.
We offer made-to-measure polycarbonate panels in standard and custom shapes, including triangular, trapezium, and bespoke designs. Simply enter your dimensions or upload a diagram for precise cutting. Despite its durability, polycarbonate is lightweight and easy to handle, designed for quick attachment to aluminium or wooden beams, ensuring a smooth and simple installation process for your new greenhouse panels. No specialised tools or skills are required!
Keep your panels looking clear by cleaning periodically with mild soap and water. Polycarbonate is an easy, low-maintenance glazing material.

Measuring Your Greenhouse
The first step in fitting replacement greenhouse panels is to accurately measure the existing frame. Make sure to measure the width and length of each panel opening. Also, measure the height at the eave and peak. Having detailed measurements of your greenhouse will ensure the proper fitting of replacement panels - remember, measure twice, cut once (or in this case, order once).
Ordering the Right Size
Use your measurements to order replacement polycarbonate panels in the appropriate standard sizes, or you can provide your dimensions to have custom panels precisely cut for an exact fit. Make sure to account for any overlap or wiggle room needed when ordering.
Preparing the Greenhouse Frame
Inspect the frame and make any necessary repairs before installing replacement panels. Check for loose screws, decayed wood, gaps, etc. A sturdy frame is crucial for proper panel fitting. Remove any remaining bits of old glazing material and clean the frame.
Installing the Panels
Attach your polycarbonate panels. In most cases, the panels are fitted into existing side and top aluminium or wood strips designed to hold the glazing in place. Make sure the panels slide fully into the frame channel.
Sealing the Edges
Caulk any gaps between the panels and frame with 100% silicone caulk. This will provide an extra layer of protection against leaks.
Following these steps will result in replacement polycarbonate panels that are correctly fitted and installed for optimal performance. Let us know if you need any guidance selecting the right panels or installing them properly in your greenhouse frame.
