Genuine Perspex® cell cast acrylic - the original crystal-clear sheet, made in the UK.
Perspex® Clear is the benchmark clear cast acrylic: over 92% light transmission, a flawless glass-like surface and the superior optical quality, thermal stability and craze resistance of cell cast production. The specifier's choice for glazing, displays, fabrication, laser cutting and engineering applications where the sheet has to be right. Supplied with Perspex®-logo protective masking on both faces.
Perspex® is the original clear perspex sheet - made in Britain for over 90 years and the brand most specifications actually name. Cell cast production gives tighter optical control, better thermal stability during fabrication and consistent behaviour on the laser bed, and every genuine sheet arrives with the printed Perspex® masking so you (and your client) know it's the real thing. When a job specifies Perspex sheet by name, this is the material that satisfies the spec.

Genuine Perspex® cell cast acrylic sheets are manufactured in the UK to premium standards and offer a versatile, high-performance solution for a wide range of applications including signage, fabrication, lighting, retail displays, and architectural features. Compared to extruded alternatives, cast acrylic provides superior optical clarity, thermal stability, and resistance to crazing during fabrication.
One of the key benefits of our product is its tight thickness tolerance of ±0.1 mm, a significant improvement over the standard ±0.2 mm. This ensures more consistent results during machining and assembly, especially for precision applications such as CNC routing and edge-lit signage. Our cast acrylic also offers high light transmission (93%), excellent surface hardness, and good weather resistance.
