Product description
This stone grey 3mm frosted acrylic sheet brings a subtle, diffused colour to any installation. The satin finish reduces glare and obscures direct visibility while still allowing ambient light through — making it ideal for partitions, splashbacks, and backlit signage.
Manufactured from cast acrylic with a satin frosted surface, this sheet delivers the premium look of etched glass without the fragility. The stone grey pastel pigment is consistent throughout the 3mm thickness, and the material resists UV degradation, moisture, and weathering for reliable performance indoors and out.
Frosted stone grey 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.
