610mm x 234mm x 20mm Greenhouse Window (3mm Acrylic)

Stronger, Weatherproof & Long-Lasting Clarity

For those looking for an extra-durable glazing solution, this 3mm thick acrylic panel is the perfect replacement for triangular greenhouse windows found in Hayes brand greenhouses. Offering superior impact resistance, this sheet is 10x stronger than glass, making it a safer, long-lasting alternative.

Clear acrylic is weatherproof and UV-resistant, ensuring that your greenhouse maintains optimal light transmission (92%) without the risk of yellowing or discoloration. Whether you're replacing a storm-damaged window or upgrading your greenhouse glazing, this custom-cut panel is an excellent choice.

We are an approved supplier of clear Perspex which is 100% recyclable, made in the UK and has a 10-year guarantee on outdoor weathering.

You can buy these panels pre-cut and ready to ship but if you can’t find the size you’re looking for you can also buy custom sizes cut to your exact requirements.

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.

For a step by step fitting guide, visit our greenhouse window installation guide page.

Well friends, she passed the first test 😁 I was a bit apprehensive about the makeshift door holding the cold at bay but it looks like it’s done the trick, especially given my (very frost-sensitive) tamarillo is still looking good. The frame is an old hartley_botanic which I’ve slowly been tidying up. I’ve set it on re-claimed railway sleepers for a bit of extra height and thanks to a fresh load of coniferous woodchip, it’s smelling pine-fresh. Re-glazed with 4mm poly-carb (cutmyplasticuk) as, although it cost a bloody arm and a leg compared to re-using the glass I had and just replacing the broken panes, most of the original clips were missing and the frame has been moved several times so I wanted a bit of give - last slide shows this was a good call. #ukallotment #allotmentsofinstagram #allotmentnewbies #gardenblogger #nodig #gardenjoy #nodiggardening #allotmentlife #gardenlife #gardenjournal #gardeningtips #vegetablegarden #growingfood #growfoodnotlawns #londongarden #potager #potagergarden #allotmenteer #greenhouse #gardencore

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.

so pleased with how our hallway is coming along 🥰 here is a little run down of what we’ve done 🎨 we painted the walls, skirting & door frames in slipper satin (paint matched at b&q) - I think I also want to do the ceilings as they need a refresh anyway 🪚 we panelled the wall longest wall which I loved doing, the most difficult part was going around the plug sockets - I ordered from cutmy.uk which was made to measure & absolutely brilliant 🎨 the panelling is painted in elephant’s breath (also paint matched at b&q) 🪞& then we added the mirrors 💡changed the light fitting 🖤 painted the little cabinet in pitch black - a bit risky but so pleased with how it came out 🪑added a bench and cushions 🌿 we bought a new (big) plant baby, bird of paradise & a large pot for the corner 🧥and some gorgey coat hooks for under the stairs made by ardovie_wood who we found on etsyuk We’re going to look for some baskets to go under the bench for shoes, and I want to get a new lamp too! And the current plan is the change the carpet to hard flooring next year. ➡️ swipe to the end to see the before photo • #Hallway #HallwayDecor #HallwayInspo #HouseUpdates #HomeDecor #HomeInterior #Panelling #GivingItAGo

LIFE LATELY 🌲✨ I realised I legit NEVER post stills anymore, and shiney reels don't always show reality. So next year I vouch to make a bigger effort to post more pictures that capture the good bad & ugly! 1. The finished stairs garland after 599 attempts at tying a bow we got there - if you saw my stories you'll know this is an achievement 🤣 2. A moment of still/ gratitude with my babies 3. 4 month milestone!! Feels like 4 minutes and 4 years all in one. 4. A small win to be celebrated - I was in overwhelm city and I forced myself out the house. Obvs felt a million times better for it so need to remember for next time! 5. My breakfast bar of dreams 🥰 so happy with how's it's turned out - just need to make my mind up on paint. 6. Nap trapped and savouring the moment. She won't be this little again and as tough as it is I would swap anything to keep these cuddles longer 🥹 Bit different from me today!! Happy Friday Homeys 🥰 CHS x
