610mm x 450mm x 24mm Greenhouse Window (3mm Acrylic)

Stronger, Weather-Resistant & UV-Protected for Long-Lasting Clarity

If your greenhouse has been damaged by the bad weather, the kids football, or even vandalism at the allotment you may be looking to replace the glass. Our 610mm x 450mm x 24mm triangular windows are the perfect solution. You can upgrade your Halls greenhouse with this 3mm thick acrylic panel, designed to provide enhanced durability and superior clarity compared to standard glass. Being 10 times stronger than glass, this acrylic sheet is shatter-resistant and weatherproof, making it an ideal choice for greenhouse glazing replacements.

Unlike traditional glass, which can crack or break in strong winds, acrylic offers long-term reliability while allowing 92% light transmission for optimal plant growth. It is also UV-resistant, meaning it won’t yellow over time, ensuring clear visibility for years to come. As a high-quality Perspex panel, it also comes with a 10-year ageing guarantee, so you can buy with confidence.

We make replacing your greenhouse windows quick and hassle-free by delivering directly to your home, so you don’t have to search for a local supplier. If you need a different size or shape, explore our custom greenhouse window options for a perfect fit.

Not sure how to fit your new panel? Our greenhouse window installation guide walks you through the process step by step.

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.
