Greenhouse Windows Details

Upgrade your glass greenhouse windows with our clear acrylic sheeting or our polycarbonate. You will still be able to view your plants whilst keeping them safe. We have also constructed a guide helping you decide on the material you buy as well as assist you in how to replace greenhouse and shed windows.

No matter the size of your greenhouse, we can provide you with clear plastic materials exactly to your specifications and measurements. We can also add options for customization should you require them. This means that all you need to do is fit the panel onto your greenhouse!

Both clear acrylic and polycarbonate are excellent alternatives to greenhouse glass panels as well as shed windows, as they are lightweight and easier to install than traditional glass. While glass would normally deteriorate as a greenhouse glass pane, either by losing transparency or warping, the long-lasting consistency of clear greenhouse windows makes them an easy replacement and repurposes your greenhouse windows - giving the whole feature a second wind.

When understanding what option is best for your greenhouse glass panels, choosing the best greenhouse plastic option is fundamental to maintaining and ensuring a high-quality grow space throughout the year.

Acrylic Greenhouse Windows

Clear acrylic sheets from Cut My are the cheaper option for your greenhouse windows, and they are up to 10 times stronger than glass. They don’t show any sign of ageing with continual use, meaning you can expect well in excess of 10 years of use from your greenhouse windows without them showing signs of deterioration.

Further to this, Acrylic Greenhouse Windows provide up to 92% light transmission, higher than most types of glass, so it becomes preferable for a number of other applications like secondary glazing or roofing. Clear perspex also has a ten year guarantee and is 100% recyclable.

Polycarbonate Greenhouse Windows

Clear polycarbonate sheeting is much tougher than acrylic, although slightly more expensive. This versatile material with a wide range of possible uses, from riot shields to external panels. This superior strong material can be purchased in varying thicknesses up to 12mm to provide further levels of insulation for your greenhouse. Two hundred times stronger than glass, our polycarbonate replacement greenhouse glass alternative is available as a durable, safer option for replacing greenhouse glass.

Show your greenhouse some love!

‌‍   10x stronger than glass
‌‍   Shatterproof

Maintainable

All of our greenhouse plastic options are equally easy to clean, with just warm soapy water and a microfibre cloth needed to ensure a hygienic finish.

Both materials we use for greenhouse windows are salt-resistant so they are good for use if you live in coastal areas.

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.

Frequently Asked Questions

What can I use instead of glass in a greenhouse?

Polycarbonate sheeting is an ultra-tough, versatile material with a wide range of possible uses, from secondary glazing to riot shields, to external panels. This superior strong material can be purchased in varying thicknesses to provide further levels of insulation for your greenhouse plastic. Two hundred times stronger than glass, our polycarbonate replacement greenhouse glass alternative is available as a durable, safer option for replacing the glass.

Is acrylic good for the greenhouse?

Acrylic is ideal for greenhouse pane replacements due to it having a higher light transmission than traditional glass. With a 92% light transmission, acrylic offers a fantastical alternative to glass for consistent high-quality optic transparency.

How thick should an acrylic greenhouse be?

Standard greenhouse glass is typically 3mm thick. As such we are able to accommodate that with our alternative plastic greenhouse window replacement options. However, by opting for acrylic you have the option to change the thickness to best suit your needs with a thicker sheet offering more protection.

Is acrylic or polycarbonate better for greenhouses?

Polycarbonate is ideal for greenhouse windows due to its versatility, though acrylic is great for those looking for a cheaper option.
