What are the advantages of using Perspex sheet?
The main advantages of Perspex sheets are:
  • high shock, abrasion and flex resistance
  • excellent weather and UV resistance (applies to clear only)
  • low density / light weight compared with glass
  • clear sheet offers excellent optical clarity
  • comprehensive range of colours and finishes
  • 100% recyclability
How is Perspex made?
Cast Perspex sheet is produced directly from monomer, cast between two sheets of high quality glass and is polymerised in batches in specially developed ovens and water baths in a carefully controlled manufacturing process.

Extruded Perspex sheet is produced from the acrylic polymer Lucite Diakon in the form of granules, and extruded into sheet.

What is Solid Coloured Perspex?
This means that the Perspex colour does not allow transmission of light (eg if you held your hand up behind a solid colour sheet you would not see a shadow).

What is Translucent Coloured Perspex?
This means that the although the Perspex colour allows transmission of a minimal amount of light you are unable to see through the material (eg if you held your hand up behind a translucent colour sheet you would see a shadow, but you would not be able to see your hand). Translucent Perspex is frequently used for light-boxes.

What is Transparent Coloured Perspex?
This means that the Perspex colour is see through. So in effect, the sheet is clear but tinted with a colour.

What is Silk Perspex?
This means that the Perspex has a frosted (anti-reflective) finish on one side of the sheet.

What is Frosted Perspex?
This means that the Perspex has a frosted (anti-reflective) finish on both sides of the sheet.

What is Fluorescent Perspex?
This is a relatively new addition to the Perspex range with an exciting fluorescent live edge, and is available in a range of colours.

The thickness of Perspex coloured sheet I want is not listed, can you make it?
We can manufacture standard colours in any thickness - subject to a minimum order quantity of approx 16 full sheets.

I need to match a particular colour, can you help?
We can manufacture Perspex to almost any custom colour imaginable - subject to a minimum order quantity of approx 16 full sheets.

How can I calculate what the Thermal Expansion of my Perspex sheet will be?
You can use this Thermal expansion of Perspex calculator to give an indication as to the thermal expansion likely at any given temperature.

I want to protect a valuable painting, which Perspex grade should I use?
Perspex VA is a special UV grade acrylic sheet which has excellent ultraviolet absorbing properties to block damaging UV rays. This is a best-selling item to museums and art galleries.

I already have some Perspex sheet, but it has a scratch on it - can you help?
Our Perspex Polish allows you to simply polish out most minor surface scratches and imperfections from Perspex and acrylic sheet

What are the dimensional tolerances on Perspex sheet thicknesses?
Cast Perspex is manufactured in accordance with ISO7823-1, which means for the thickness range of 2 to 25mm, a production tolerance of +/-10% plus 0.4mm (eg 8mm cast sheet could vary from 6.8mm to 9.2mm).

Extruded Perspex is manufactured in accordance with ISO7823-2, ie to a thickness tolerance of +/-10% for sheet thicknesses below 3mm and +/-5% for sheet thicknesses of 3mm and above.

Does Perspex sheet have a fire rating?
CAST Perspex achieves a UK Class 3 fire rating. EXTRUDED Perspex achieves a UK Class 4 fire rating.

How can I clean Perspex sheeting?
The best method for cleaning Perspex sheet is by washing with a solution of luke warm water with a drop of washing-up liquid, using a soft cloth to loosen any dirt and grime. Then, rinse with cold water and dry with a very soft cloth to prevent water spotting. You should not use chemicals, glass spray, or other abrasive cleaning materials, nor should you use any form of scraper or squeegee or other sharp instruments.

How is the light transmission of Perspex calculated?
When light transmission values are given, they are for a nominal 3mm thickness. The light transmission of Perspex varies according to thickness. Colour numbers with the letter "T" are constant transmission products. This means that the product has the same light transmission throughout the thickness range.

Is there a Perspex colour which just transmits infra-red light?
Yes, Perspex Black 962 will only transmit infra-red light.

How do I work out the weight of a Perspex sheet?
By using the specific gravity of Perspex sheet (1.19) you can use the following simple formula to work out the weight of any given sheet size:
Length (in metres) x Width (in metres) x Thickness (in mm) x 1.19 = Weight in kg

I'd like to make a Perspex Splashback for my kitchen - is this possible?
Many of our customers have used our range of Perspex colours to make modern splashbacks for kitchen areas. We can cut Perspex sheets to almost any custom size - and we can also include cut-outs for sockets etc if required (we just need a drawing from you showing dimensions). To discuss your project in more detail, please contact us.

Please note that Perspex must not be positioned near to any naked flame (eg gas hobs), nor exposed to temperatures in excess of 75 degrees C.

Can I use Perspex in my bathroom?
Perspex can certainly be used in bathrooms. You can also use our range of adhesives and sealants to mount and seal around the edge of the Perspex sheets to ensure a water-tight finish. Depending on your wall surface, you may need to pre-mount your Perspex sheet to a board (eg MDF) prior to fixing to achieve a sound, flat finish.
