3mm Sandstone Brown Coloured Acrylic S2 5T18

Combining a muted sandstone brown pastel tone with a smooth frosted finish, this 3mm acrylic sheet scatters light evenly across its surface to create a contemporary, diffused aesthetic. It works as effectively for privacy glazing as it does for decorative interior panels.

Manufactured from cast acrylic with a satin frosted surface, this sheet delivers the premium look of etched glass without the fragility. The sandstone brown pastel pigment is consistent throughout the 3mm thickness, and the material resists UV degradation, moisture, and weathering for reliable performance indoors and out.

Frosted sandstone brown acrylic is widely used for privacy screens, room dividers, bathroom panels, lightbox fascias, and decorative feature walls. It machines cleanly with laser cutters, CNC routers, and standard hand tools, and can be thermoformed for curved components. Laser engraving produces a striking contrast against the frosted surface — popular for personalised signage, awards, and gifts. Available cut to size.
