Description Clear cast (GS) PERSPEX® sheet 4 mm

PERSPEX® sheet is widely used as a replacement for glass. These transparent coloured sheets are not only thirty times stronger than glass, but also half the weight. This type of PERSPEX® is called “cast” or “GS”. This material was cast into large sheets during production, making the sheet stress-free. This makes this clear PERSPEX® sheet suitable for extensive processing such as sawing, drilling, milling and (hot) bending.


The PERSPEX® sheets are UV-resistant, making them highly suitable for indoor and outdoor applications. The sheet has a thickness tolerance of 10 percent; this means that the thickness of the plate can actually differ from the thickness stated on this page. The sheets are supplied with a protective film on both sides and are sawn to the required size for free.
