This extruded 3mm Silver Mirrored Perspex Acrylic Sheet measures 600mm x 400mm. Mirror Perspex sheets are extruded clear sheets with a high quality mirror coating applied to one face.

They make an an excellent alternative to glass mirrors. Shatter proof, marr-resistant and 17x stronger than glass, they can be used indoors for decoration or outdoors in the garden.

As acrylic mirrors are more flexible than glass they must be fixed to a flat wall/surface. If you are fitting it to a wall which is not flat, it is best to fit it first to something rigid such as a piece of MDF.


  • Mirror finish.
  • Shatter proof.
  • Very low light transmission.
  • Easily laser cut, drilled and thermoformed.


Mirror Perspex acrylic sheets have many applications such as display, point of sale, artistic and architectural installation, and of course replacement mirrors.

Working with Perspex acrylic sheets:

Perspex is a versatile material that can be cut, drilled, laser cut and thermoformed. Note when laser cutting place the rear side of the Perspex to the top, so the laser is not bouncing off the reflective surface.

Perspex is a thermoplastic which means that when it is heated above 140-180C it becomes flexible. This allows the material to be formed into the requiBlue shape or bent. Once the material cools below 85C it becomes rigid again.

Perspex sheets are often shaped using a CNC router or laser cutter. The edge of laser cut Perspex has a pleasing polished look. If you look carefully at the edge of a piece of laser cut Perspex you can often see slight vertical lines that are caused by the pulses a laser uses when cutting.

If you want to get a perfectly smooth finish on the edge of piece of machined Perspex a polishing technique can be used. Typical polishing techniques include diamond polishing and flame polishing.

It also possible to etch the surface of a Perspex sheet using a laser cutter. This can produce some very pleasing visual effects. The Perspex sheets have a protective film on both faces. If you are etching the material then this should be removed from the surface that is to be etched. If you are just laser cutting then this film can be left in place (if you wish) as it does not create any harmful gases when it is laser cut (unlike PVC).

More detailed information and resources on working with Perspex can be found in our resource section.

Is this acrylic suitable to cut on a laser cutter?

    It cuts fine with a laser cutter. Just remember mirror side down when you load it in!
