Details

Protecting your greenhouse windows from footballs and stones has never been an easier option. By replacing them with either of our clear acrylics, high-impact polystyrene, or polycarbonate greenhouse plastic, you can have the reassurance of safety and consistency for the future of your building.

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.

Up to 10 times stronger than glass our clear Perspex® acrylic sheets don’t show any sign of ageing with continual use, meaning you can expect at least 20 years of use from your clear acrylic sheet without showing signs of deterioration.

Further to this, Clear Perspex® Acrylic sheeting also provides up to 92% light transmission, higher than most types of glass, so becomes a preferable option to glass for use in windows or roofing.

Clear polycarbonate sheeting on the other hand 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 insulating 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.

Lastly, high-impact polystyrene (HIP) is the cheaper option and much like polycarbonate is designed for functions that require enhanced impact resistance ideal for use as a greenhouse glass alternative.

However, when compared to the other two sheeting, HIP sheets do have a noticeable optical difference often showing vertical lines distorting light slightly which is worth considering if you are aiming for total clear optics. For this reason, our polycarbonate or clear acrylic sheets are perfect for greenhouse plastic window replacements, though HIPs is a great alternative if optics are not of concern.

All three of our options as an alternative to greenhouse glass panels 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 acrylic, polycarbonate, or HIP panels makes them an easy replacement, repurposing your greenhouse plastic windows and giving the whole feature a second wind.

We are able to provide HIPS, clear acrylic, or polycarbonate exactly to your specifications and measurements, as well as adding options for customization should you require. We have also constructed a helpful guide to assist you with your installation.

Key Features

Excellent Clarity

Clear Perspex® acrylic, polycarbonate, and high impact polystyrene sheets give excellent optical clarity, ranging up to 92% light transmission, higher than most types of glass, making our clear plastic sheets an advantageous option for use in windows or as a skylight. 

Versatile

Clear Perspex® acrylic sheets are incredibly durable, so are often used as a secondary glazing alternative to glass, as it is resistant to impact and is shatterproof, making it a safer option. Further, clear plastic sheets are particularly useful for sheds and around the home with children and pets.

Comparably, our polycarbonate is 300 hundred times stronger than glass and 30 times stronger than our Perspex® acrylic sheets, as well as being shatter-resistant. You can expect at least 20 years of continued use from these long-lasting panels without showing signs of deterioration.

Weather Resistant

Clear acrylic sheeting is UV and weather-resistant, as well as being resistant to prolonged exposure to sunlight. In addition, clear acrylic sheets are also resistant to most chemicals and have a low moisture absorption rate, so clear plastic sheets are useful for a host of different environments and are perfect for outdoor applications.

Durable

With a higher impact tolerance to acrylic sheeting, clear polycarbonate sheets make a stronger, long-lasting alternative to both acrylic and glass. At its thickest point polycarbonate is also resistant to bullets, and its brake form is a tenth of an inch thick.

Malleable

Clear cast Perspex® acrylic sheeting is easy to fabricate and can be cut, drilled and shaped to any requirements, so it’s a flexible material to work with. The cut surfaces can be polished and sanded easily for a more professional finish to your sheeting.

Inexpensive

HIPs works out at one-third of the price of clear acrylic relative to square meter sheets, allowing greenhouse windows to become an accessible inexpensive task to complete. 

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.

Frequently Asked Questions

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 how versatile it is, though acrylic is great for those looking for a cheaper option.

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 insulating 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.
