    With up to 92% light transmission, it offers excellent optical clarity, giving you a true glass-like appearance without the fragility.

    Ideal for UK Homes and DIY Projects

    Thanks to its slim 3mm thickness, this acrylic sheet is easy to cut, drill and install. It’s commonly used across the UK for:

    • Picture frame glazing
    • Secondary glazing panels
    • Shed and greenhouse windows
    • Protective covers and display panels
    • Craft and hobby projects

    It’s suitable for both indoor and outdoor use and performs well in typical British weather conditions due to its UV resistance and durability.

    Quality 3mm Cast Acrylic Finish

    Manufactured using the cast process, Perspex® acrylic provides a superior surface finish compared to standard extruded sheets. It machines cleanly and offers improved strength and long-term performance.

      The delivery was delayed by three working days - because of the cruel hot weather I presume. Not PerspexSheet's fault! Perspex is exactly right in size and finish. 5 stars for each category. Thank you.

      I bought clear Perspex for two reasons. The first one was to protect the top of my new chests of drawers. The second one was to vent my ac out of the window. What a difference they both make. I’m so pleased with both cuts. Both cut to precision. I requested and paid for express delivery. The Perspex was cut and with the courier on the same day meaning my Perspex arrived a day early. I can’t ask better than that.
