Details

20mm Acrylic Sheets are a great alternative to glass, as they are cheaper, 10x stronger and much lighter than the equivalent thickness of glass. With a high gloss finish, they can be great for more creative purposes such as Acrylic photo blocks or display blocks as even at this thickness, clear acrylic maintains its excellent light transmission.

✔ 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.

What is the light transmission of 20mm clear acrylic?

Our 20mm clear acrylic provides approximately 90% light transmission with minimal haze or distortion.

The six sheets I ordered were cut and despatched the day after I submitted my Order. They have been fitted in my summerhouse and certainly look the part. They are far stronger than the thin greenhouse type glass previously fitted. It also takes away the danger of one of my grandchildren sticking their hand through it. Excellent service overall.

Ebony Bedekier, 17th August

Amazing company. We decided to build our own wooden framed greenhouse and we needed some windows. Rather than traditional glass windows, we did a bit of research and came across this company. We ordered 14 custom made windows and they arrived within a couple of days. The windows were all well packed and the service was fab. I have even recommended this company to my dad for his self built shed.

A good quality product (two acrylic sheets, replacement shed windows). Well protected for transport. Quickly cut. I collected. Make sure you go to the address they supply for pick up and don't, like me, just head to the first building I saw, on the same industrial estate, with their name on it. However, somebody there politely sent me in the right direction!

Chris L,

I’d not used an online company before for shelving. Just happy to go to the local DIY. Then, I discovered Cut My, the selection, information easy to follow. Plus, varied wood types to choose from. Ordering easy. Great shelving and look good too! Delivery was quick but driver didn’t allow the time for me to check the products before driving off is my only small niggle as your website suggests to do so. Recommending to all friends.

PPP,

Excellent service. Easy to use and arrived very quickly. Well packaged to prevent any damage and cut perfectly

Alexander Thomas,

The webb site was easy to follow , I liked the fact that I could get a piece of marine ply cut to exact size and thickness I needed. I am an Artist and use it for streching A1 watercolour paper. This is my 3rd purchase from My Cut. It came quickly and well packaged and very clean. The board was cut exact and had no splintery edges .I chose to sand the edges and corners gently myself . Thank you , very happy.

Mrs ANGELA NORMAN,

Ordered a few times from this company and everytime the product has been Amazing , cut perfect and quality

Great quality, but the cut was 3mm too small so didn’t fit the enclosure. Arrived in good time and perfect quality material.

Phil D,

Great service, I would use them again.

They really have spotted a gap in the market. I have used them a few times, recently for bespoke wardrobe shelves. The website is easy to use and the shelves were perfect, arrived within 3 days. Highly recommended!

MJL,

Size was accurate to the mm. Edges were nicely trimmed.

J.E.,

Fantastic experience and first class service. Order easy to place and arrived far sooner than I thought. Would highly recommend.

mark knighton,

I needed a piece of 3mm clear polycarbonate, known to me as Lexan but that could be a trade name. This was required to repair an outside meter cupboard door. I ordered the required size from CutMy, who I found on line that did exactly what I wanted cut it to my size, no waste and ready to use. It was packed superbly and arrived as it would have been shipped. I would recommend Cut My to anyone and will use again myself on my next project.

Ivan Ford,

Pete Thomas,

I had used this firm before for greenhouse panels broken by falling apples. The panel arrived with heavy duty packing in perfect condition, cut to the millimetre and fitted perfectly as a replacement roof panel for the greenhouse. I was kept in touch with the delivery details and times. Perfect service and quality product

Very fast service, all pieces cut to my exact measurement, nothing could be easier. So impressed.

Malcolm Bennett,

Broke a pane of glass whilst erecting a greenhouse, getting glass from Rhino would have been too difficult so used CutMy and the piece sent was perfect. Only issue we had was their website that got confused over our location on the UK mainland and it cost us more in the end.

Richard Baker,

A fast service and a well-protected package. My heart sank when I saw the oversized box, but the cut-to-size plastic sheet inside was an exact match to my measurements. The extra space was just clever, safe packing. What Went Right: Exact Size: The plastic sheet matched my numbers. Fast Delivery: The order arrived quickly. Great Protection: The large box kept the sheet safe from harm. Room for Improvement: Box Size: A smaller box would save space and stop the initial panic.

Great service from them.

Clive,

Firstly I am hopeless at DIY and I mean really bad.BUT this has made it fool proof. I sent the measurements and everything came spot on, fantastically easy to do and now my plant room/office looks like a professional did it. I had x2 long desk tops and 5 long shelves bespoke to my size room. 100% recommend. I'll be back for my next venture

Mr Thomas,

Right size, good quality, quick service. And look even better once my son realised he needed to remove the film from both sides.

Andrew Carey,

I couldn’t believe I got the price of one elsewhere for the cost of two from Cut My! Such a great deal, and the quality is excellent. The delivery was also fast and efficient. I would definitely recommend Cut My to anyone looking for great value and quality.

Bolanle,

I ordered 2 Dibond silver discs. They arrived very quickly, but unfortunately both had dents in the sides. I sent an email with photos straight away. A few days later I got a reply from Penny who quickly sent out replacements.

Lynsey Thomas Art,

Finally I have these panels I wanted for ages. I found them to be expensive but at least they were precut to my measurements, Ivtried to save some money by having them unsealed and seal them myself. They arrived covered in black dust and caused a big mess. I’m glad these were at my own property and not a clients asxi would have had complaints

Miss M Dias,

Perfect cut from my dimensions and fitted lovely.

Quality and speedy delivery. Item was bang on and was easy to install. Highly recommended and would certainly use again

Paul Sandbach,

Amazing service, easy to order what was needed and fast delivery!

Connie Duxbury,

I ordered a round plastic cover for my outdoor table as an alternative for the glass one that shuttered in pieces during the storm . A great alternative as so much cheaper than a glass one ., However the central hole for the sun umbrella was in the wrong place and I expected it to be my own loss . So I can really say that I was impressed by the prompt after service at resolving the issue and sending me a new one . So I would use again and recommend as a very satisfactory product and service . Thank you .

Veronique Mackintosh,

A very good idea and a good product, but the delivery a little slow but didn't effect overall timing.

Kevin Winman,

One of the best online shopping experiences. From ordering via the easy to use website, through confirmation and shipping updates, the process was mega efficient, and glitch free. This is the second time I have used Cut My and having been delighted the first time, I returned with confidence for my main kitchen top which arrived on time, as specified, securely packed and is a quality product. Couldn't be more delighted and couldn't recommend more highly from product to price.

Patricia,

Amazing shelves! Look like real wood and the best price and quality I found on the market!

Representative I spoke with was extremely helpful after the need to call happened because credit card payment did not work. She was friendly and professional and my order was expedite and delivered quickly. However the delivery company you used were not so kind- they rang the doorbell-took me less than 30 seconds to reach the door but they had already left a heavy package propped against the porch door. Instead to wait for me to arrive and request they place it in the garage.

ACE,

I really like the product and the end result being my table. Also they dealt with a delivery issue which was good.

Stephen Munday,

The order was delivered as expected and cut to size. No problem
