Details

✔ Easy to clean and maintain
✔ Diffuses UV light
✔ 100% Recyclable

✔ 10-Year Guarantee with Perspex®
✔ High gloss contemporary finish

Frequently Asked Questions

What types of projects typically use 20mm acrylic?

20mm acrylic is often used for large structural applications where maximum rigidity is needed, such as awards, room dividers, countertops, display cases, machine guards, and thick aquariums.

What size 20mm acrylic sheets are available?

We stock 20mm clear acrylic sheets up to 3000mm x 2000mm.

Does 20mm acrylic become flexible or sag over time?

No, 20mm extruded acrylic maintains its rigidity and shape indefinitely. The thicker material resists bowing, bending and flexing much better than thinner acrylic.

I am very happy with the 10mm acrylic sheet. I had to make a media wall and this went in front of the tv to protect the screen from impact from my disabled son. Does the job very well and is solid.

Michael Welsh,

It was easy to order. I gave the measurements and the acrylic mirror was cut to the exact size. It arrived very quickly. The purpose for this mirror was to fit in a gold effect ornate frame and is to be used as a prop on which to affix the individual table plan for my daughter’s wedding. It’s perfect for this. However, if I was to use it as an exact mirror reflection without distortion it would need to be fixed to a backing.

LesleyClark,

Easy ordering, great options, fare price with super fast delivery. Will definitely use again. Thank you.

Dawn M,

Competitive pricing, quick delivery, we definitely use again.

Rob,

Made my order via their website which was straightforward and easy to use. Billing and delivery were efficient ...the whole process was very simple. The product...mdf strips for a wall panelling project were accurately cut to size and suitable for the job. Very pleased with their service and product...will definitely order again and recommend them to anyone looking for a bespoke service at a competitive price.

Outstanding customer service, great interactive website, messages dealt with quickly by helpful knowledgeable staff. Superb product and excellent delivery schedule.

Paul Clark,

Needed to replace a bit of flooring. Could have bought a board and cut if to size. For a price less than the board got it cut to size from here. As a non trade with no tools or skills this was easiest.

bobc95,

Excellent customer service. Can actually speak to a live person on the phone. I am so happy with my experience. Love my bedroom after using these panels My favorite room in the house

Claire Barley,

The delivery was on the date promised. The acrylic we ordered was of high quality and the correct thickness for our job. When we opened the packaging the cream colour looked an exact match to the colour on the website and the colour we wanted, however when the protective covering was removed, it is much yellower than we wanted, hence only 4 stars. At some point we will remove it and replace it with some blue. I would use the company again, as reproduction on a screen is difficult.

Mrs Burchell,

Packaging was carefully considered and well packaged. Delivery was fast. Item was perfect. Good value for money and good ordering experience

Kev,

I couldn't place my order online (system error on my computer) so I spoke to someone and they completed the order within seconds, sent the invoice and processed my order. Within a week my custom shelves had arrived, sizing was perfect! Excellent and efficient service with prompt delivery. Will be using again.

Kirsty Farrugia,

I ordered a custom 5mm double-sided frosted acrylic sheet (1420mm x 430mm) with two 130mm diameter holes to mount a dual-hose portable air conditioner using magnetic strips. The acrylic itself is absolutely fantastic. CutMy executed the dimensions and the hole cutouts perfectly to my exact specifications. The frosted finish looks great and the material quality is excellent. Unfortunately, my project is temporarily stalled because the AC retailer accidentally sent me a single-hose unit instead of a dual-hose model. To make matters worse, dual-hose units are now completely out of stock everywhere in the UK. I am currently facing a dilemma where I might have to manually modify this perfectly cut piece of plexiglass to accommodate a "hose-in-hose" configuration instead. Despite my external issues with the appliance, CutMy did an amazing job with the fabrication. I already have a few other projects lined up for later this year and will absolutely be using them again. I can safely recommend this company for precise, high-quality custom plastic cutting.

Michael Shelley,

I orderd on line ,and had a great service, grest product. Very happy.

lynn short,

So easy to find the plexiglas i needed, exact measurements, brilliantly packaged and arrived bang on time. Price is great too

Richard,

I ordered two sheets of clear perspex with a hole in each and that's exactly what I received. Exactly the sizes I asked for and they arrived in good time although getting the protective film off was a bit of a bugger.

Kevin,

i made an order then changed and added to it, this company were so helpful, realised i then needed two further sheets, i did not order and did not write the sizes down, the lady at this company then sent me all the sizes and added a cost for the additional items and kindly emailed me, at my age i need reminding the went above and beyond for my super nice company to deal with and order arrived within a few days no problems at all. 100% recormend this company to deal with, i used them during lock down for a large shed i built in the garden, super nice people to deal with.

Derek Betts,

Brilliant service. The quality of the wood was exceptional and looks fabulous when lacquered. I chose a nice piece of oak veneer to replace my cheap-looking white MDF desktop. Now the desk looks premium. Quick delivery and a very reasonable price. I'd definitely use them again.

LS,

Excellent service, the parts ordered were top quality. It arrived before the expected delivery date. The delivery driver communicated the deliery drop off time throughout to make sure I was around to take delivery. I will be using this company form here on out, you cant get a better all round service than these guys! 12/10 would reccomend!

The experience was great. Timely delivery. Good quality Panel. And excellent customer service.

Saba Zareem,

I ordered a clear piece to help seal my window as it was an outward hinging window on the top floor of the house, so fabric ones would collecting rainwater and would go mouldy. It was exactly the size requested and the cutout was perfectly measured to the point that the exhaust hose didn’t need anything to hold it in place as the fit alone keeps it right where I want it.

Ben Smith,

Excellent service. Website and ordering process was easy to use. High quality product.

N Robinson,

I ordered a table top. It was cut and delivered promptly. Sadly the corner was damaged in transit. If I pushed that corner against the wall as intended, the damage is not visible. The perfectionist in me wanted a replacement but the realist won out ...only I know its damaged. Cut my offered to replace the table top immediately but when I contacted them offered a reasonable discount. This is just good flexible service.

Neil,

Great service and excellent product has made air conditioning much better in bedroom. Would use again and recommend

Chris Giles,

The choice of woods the colours and the price. The service was excellent and updates on delivery were good except for a delivery driver failing in his job and declared we weren't in !!!! However, there was a phone number to contact the delivery company and the goods were delivered the following day. The shelves fitted perfectly and finished off a cupboard beautifully

Rosemary Petheram,

Good product, good staff, would use again.

Mr/Mrs Rodger,

Good communication from the company and despite a day delay from the original quote, it arrived quickly. The product is exactly as specified with the the only downside being that it is a little expensive. BUT, it works!

Alastair Armstrong,

Great communication and fast delivery, well packaged. Will cut to your own dimensions. Will use again…

colinspike123,

Ordered two 18mm melamine mdf shelves for a wardrobe and they arrived promptly and accurate to size. I like the fact you can choose which side/s to add edge banding to on the website. Delivery was a bit pricey but worth it to know you are getting a decent product.

Casper,

The acrylic was nice and thick fitted my window perfectly. Absolutely great for my air conditioning hose to go through the hole which again was a perfect fit. Communications from the company were excellent. Wouldn’t hesitate to recommend them.
