3mm Perspex Acrylic Sheet Details

3mm Acrylic Sheets are one of our best-sellers. They can be used for a vast range of purposes, from artistic projects to practical home renovations. 3mm extruded sheets are a cheaper, stronger and lightweight alternative to glass panels and they are outstandingly weatherproof and UV resistant - meaning you can use them both indoors and outdoors. Because of this, 3mm Perspex sheets are often used for secondary glazing to keep your home warmer and as replacement greenhouse glass and shed windows.

Since 3mm clear sheets are more impact resistant than glass, they can also be used as a lightweight replacement for picture frames and art and craft projects. They are also 100% recyclable if you are looking for a more environmentally friendly option.

Perfectly cut to size by us, 3mm Perspex sheets also come in coloured, opal and frosted so they are also a great material for a kitchen splashback or bathroom splashback. If you are unsure what finish you would like, you can order a sample from us. We suggest that if you are using a larger sheet, then you use a thickness of 5mm or greater for extra strength. You can also order any of our clear acrylic samples in all of our thicknesses from 2mm to 30mm.

If you purchase your 3mm Perspex sheets in custom sizes from us, you will receive exceptional customer service, speedy delivery, and precise cutting methods that guarantee high levels of accuracy. Our cutting technique is accurate to within +/- 1mm, and we also provide the option of polished edges for sheets used in situations where appearance is important.

If you are looking for something more eye-catching, have a look at our Perspex® coloured acrylic sheets!

Key Features of 3mm Perspex Acrylic Sheets

Clarity icon

Excellent Clarity

3mm Clear Perspex Sheets give exceptional optical clarity, even in thicker blocks. They transmit 92% of all visible light, making the light transmission higher than most types of glass. They are a great option for use in windows or as a skylight.

Malleable

Malleable

3mm Acrylic Sheeting is easy for us to fabricate and it can be cut, drilled and shaped to any of your requirements. The cut surfaces can be polished and sanded easily for a more professional finish to your sheeting.

Durable key feature

Durable

3mm Acrylic Sheets are incredibly durable, so are often used as a Secondary Glazing alternative to glass. They are also particularly useful for sheds or around the home with children or pets. 3mm plastic sheets have good resistance to impact becoming a safer option in many environments. Perspex is internationally recognised as a safety glazing material meeting the requirements of ANSI Z.97 and BS 6262.

Weather Resistant Key Feature

Weather Resistant

3mm Clear Acrylic Sheets have outstanding resistance to outdoor weathering. They are also UV resistant, so can endure prolonged exposure to sunlight. 3mm Perspex sheets have a low moisture absorption rate, so they are useful for various environments and are perfect for outdoor applications. They are manufactured with UV-stable molecules and retain their stability and transparency over time.

Lightweight key feature

Lightweight

3mm Perspex weighs half as much as an equivalent glass pane, making installation, transportation, and handling an easier option than other materials.

Maintainable icon

Maintainable

The high gloss surface of 3mm Perspex makes it easy to clean, keeping maintenance costs to a minimum. All you need is warm soapy water and a Microfibre cloth needed to ensure a hygienic finish. You can also Polish a 3mm Acrylic sheet to buff out any scratches.

Built to last

Built to Last

3mm Perspex is a material that is intended for use in applications that require longevity. A standard Acrylic Sheet is capable of withstanding outdoor weather conditions for up to 10 years, and the manufacturers guarantee that there will be no significant changes in its appearance or performance during that time, even when used outside!

Food Safe

Food Safe

3mm Perspex Acrylic Sheets comply with current EU and American (FDA) food contact regulations. Please note that food contact compliance testing should be carried out on finished articles and not flat sheet samples. For further information please contact the Perspex sales office.

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.

Technical Sheet

Frequently Asked Questions for 3mm Acrylic Sheets

What’s the difference between 3mm Perspex and 3mm Acrylic?

Perspex is a brand of acrylic plastic. They are the same.

What's the difference between 3mm Acrylic and 3mm Polycarbonate?

Acrylic sheets are cheaper and more scratch resistant than polycarbonate, however, Polycarbonate is 30x stronger than acrylic so it is a more impact-resistant alternative.

Can I get samples of your 3mm Acrylic?

You can request samples of any of our products: When on the store page for the material you are interested in, first select the thickness you want, then scroll down and find the "Request Sample" button. This will add one sample unit to the shopping cart. Make sure to check your shopping cart before checking out.

Acrylic samples come as 10cm squares and are intended to let you see the colour or finish in real life. For coloured acrylic, sometimes we won't have sample stock of the exact thickness you ask for, but you'll still get the right colours. Clear and tinted samples will always be the correct thickness as the thickness can be important for the properties of the product.

Do I need polished edges?

If your item is going to be on display and is not going to be set into a frame, we recommend opting for polished edges when possible. This will leave the edges as smooth and transparent as the surface. Without this, your item may have slightly visible tool marks along the cut surfaces. This is particularly important for items that will be handled, as the edges would otherwise be rough. The effect of a polished edge will be more visible on thicker sheets of acrylic.

Is 3mm Clear Acrylic suitable for secondary glazing?

We would recommend 3mm acrylic for secondary glazing, and for larger windows, you would benefit from a thicker 3mm sheet to provide rigidity. If you need something stronger than acrylic, then we also supply cut to size 3mm polycarbonate for secondary glazing.

Is 3mm Perspex food safe?

Perspex Acrylic Sheets comply with current EU and American (FDA) food contact regulations.

Why is my Acrylic the wrong colour?

All of our acrylic products will be shipped with a thin protective film covering both faces. This could be a variety of colours: blue, green and white are common, and may not have any branding or logos printed on it to make it obvious that it’s there. The cutting process can sometimes melt the film at the edges, causing it to stick very tightly to the surface of your acrylic, making it tricky to peel off. Work at the edges or corners carefully with a craft knife to make it release, then peel it off carefully.

If you are doing any installation or modification, you might want to leave the film in place while handling your new Acrylic panels, to minimise scrapes and prevent fingerprints.

Important note about our acrylic splashbacks: If you have ordered one of our premium or budget splashbacks, then it will have a protective foil or vinyl on the back of it. Do not peel this off as it is there to prevent any adhesive from showing through the sheet. The protective foil will have a blue sticker on it informing you not to peel it off.

Is 3mm Perspex heat resistant?

Perspex sheets will melt at high temperatures or from exposure to direct flames. The melting point for 3mm Perspex is 80̊C so they cannot withstand extreme temperatures.

Can I put 3mm Acrylic behind a hob?

Electric, ceramic and induction hobs are safe to have acrylic panels behind them but there must be at least a 50mm gap between the panel and the hob. The safest option is to use a glass splashback for gas hobs. Please see our splashbacks page for more information on cooker types and acrylic.

Is Cut My able to fabricate my product?

We can cut to various sizes and shapes out of flat sheets in a range of thicknesses.

Can 3mm Perspex be painted or printed on?

Yes, 3mm Perspex can be painted or printed on as it has a smooth flat surface. However, choosing the right type of paint or ink is important to ensure adhesion and durability. It's also important to follow proper preparation and application techniques to avoid smudging or other issues.

How can I clean 3mm Perspex?

Keeping your 3mm Perspex clean and hygienic is easy to maintain, as all that is required is warm soapy water and a microfibre cloth. Please avoid using abrasive cleaners or materials, as these can scratch the surface of the material.

How resistant to scratching are your Acrylic Sheets?

Acrylic is not as scratch resistant as a similar panel of glass, but light surface marks can be more easily buffed out from acrylic. We offer a higher scratch protection finish on our 6mm Acrylic if you need extra safeguarding.

How can I remove scratches from 3mm Acrylic Sheets?

You can easily remove scratches from mirrors with a microfibre cloth and a high-quality polish. Following the instructions on the polish, the scratches will be removed using small circular motions.

How can I cut 3mm Acrylic Sheets?

While it is possible to cut acrylic sheets yourself, we do suggest that you request it cut to size before ordering as we can expertly and safely meet your requirements. We use a variety of tools here at Cut My, including saws, routers and lasers and our staff have plenty of safety equipment and knowledge of the correct techniques for cutting acrylic sheets. If you must cut acrylic sheets yourself, you will need a skill saw with an acrylic blade or a router to prevent chipping.

How do I attach 3mm Perspex sheets to other materials?

3mm Perspex can be attached to other materials using a variety of methods, including screws and adhesives. The specific method used would depend on the intended application and the materials being joined.

Is 3mm Perspex recyclable?

3mm Perspex is recyclable, however, as it’s not bio-degradable the process is not as easy as putting it in your recycle bin or taking it to a bottle bank. But you can re-use Perspex by cutting larger sheets into small pieces and forming them into other products.

Does 3mm Acrylic block UV or infrared?

Acrylic Sheets are resistant to UV, however, they don’t block it. All of the Perspex sheets that we stock are also not fully infrared blocking.

The quality of the product was excellent. Without holding it I would have thought it was glass. It was expertly cut to my specifications and did the job that I needed it for. The reason I docked one star for 'value for money' was because I was charged a small order fee which significantly added to the cost of the order. However, I knew about this before ordering and it would certainly not deter me from using this company again.
