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.

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.

Delivery depends on the size of your order

I was very satisfied with the quality of the clear acrylic sheets, as well as the communication and production/delivery times. I used 3mm and 4mm sheets for my Georgian sash and case windows as secondary glazing. I am pleased with the results. The acrylic sheets look great and effectively serve their purpose. They provide a beautiful and efficient solution to reduce heat loss in my listed property.
