610mm x 445mm x 12mm Triangular Greenhouse Window (3mm Acrylic)

Durable, Weatherproof & Designed for Optimal Plant Growth

Bad weather, the kids playing football, or even vandalism at the allotment may mean you’ll need to replace broken glass in your greenhouse. For extra durability and long-lasting clarity, this 3mm thick acrylic panel is the perfect greenhouse glazing replacement. Its shatter-resistant properties make it 10x stronger than glass, ensuring that your plants and vegetables stay protected from the elements while still receiving maximum sunlight.

With 92% light transmission, this panel lets in more natural light than most types of glass, providing your greenhouse with a brighter growing environment. Unlike traditional glass, it won’t yellow or degrade over time, thanks to its UV-resistant properties. Plus, as part of our high-quality Perspex range, it comes with a 10-year weathering guarantee for added reassurance.

We deliver these panels directly to you, eliminating the hassle of finding a local supplier. Need a different size? Our custom greenhouse window service allows you to order panels in any shape or dimension. For a quick and simple installation, follow our step-by-step greenhouse window installation guide.

Please note that greenhouse windows will not need polished edges, however, some of our standard sized stock may have polished edges depending on which machine we have used to cut them. This helps us to utilise our materials and machinery and therefore minimise wastage.

100% Recyclable

Perspex® Acrylic is 100% recyclable. Waste products can readily be recovered from the original raw material (the monomer) and re-used in a new sheet.

Perspex® has been manufactured in the UK for over 85 years and still takes place on the same site in Lancashire as it did in the 1930s. This short supply distance to our UK customers helps reduce ‘product miles’ from the manufacturing plant to the end user.

Numerous different investments have already been made by Perspex® to lessen the impact on the environment. Annual waste consumption has been reduced by 24 million litres, and almost 800 tonnes of carbon dioxide have been saved every year as part of a hot water recycling project. At Cut My, we work to be more sustainable by using all of our offcuts to heat our manufacturing facility. We are also currently working towards reducing our packaging.
