Custom Cut-to-Size Acrylic Greenhouse Windows

A Strong, Affordable, and Safer Alternative to Glass

If you need to replace a broken or missing greenhouse window, our clear acrylic sheets are the perfect alternative to glass. Acrylic is 10 times stronger than glass, making it far more breakage-resistant - especially during storms or high winds. Unlike traditional glass panels, acrylic is lightweight, shatter-resistant, and much safer, reducing the risk of injury from dangerous shattered glass in your garden. The durability of plastic against impact ensures a long-lasting performance for your gardening needs. With fewer replacements necessary, you will save money in the long run!

Custom-Cut for a Perfect Fit

We understand that greenhouse window sizes can vary, which is why we offer a fully bespoke cutting service. Whether you need a standard rectangular sheet or a more complex triangular or trapezium shape, we can provide the perfect fit for your greenhouse. Simply input your dimensions or upload a diagram with detailed measurements and we can cut the sheets precisely to your exact measurements. 

Crystal Clear & Built to Last

Our clear acrylic sheets are designed to withstand the elements while maintaining exceptional clarity. With 92% light transmission, acrylic allows more sunlight to pass through than most types of glass. The enhanced light transmission boosts photosynthesis, promoting healthier plant growth. Unlike some glass panels, our acrylic is also UV-resistant and will not yellow over time, keeping your greenhouse looking pristine for years. Plus, with a 10-year Perspex® guarantee, you can trust that our acrylic panels are weatherproof and built to endure outdoor conditions without fading or deteriorating.

Easy Installation

Replacing your greenhouse window is simple thanks to acrylic’s lightweight nature. At half the weight of glass, acrylic is much easier to handle and install. We’ve also put together a guide on how to replace a greenhouse and shed windows

100% recyclable logo

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.

Difficult to tell from the toughened glass it replaced. Light but strong it took only a few minutes to put in place. If I need to replace more glass panes in future I'll certainly use this product. Highly recommended.
