Plexiglass mirror is a "reflective" sheet. There are a lot of applications where acrylic mirror (Plexiglass mirror) works very well. It is NOT intended to replace the quality reflection of a glass mirror. That said, you should consider plexiglass mirror in applications where safety is a major concern as plastic mirror is very difficult to break and if it does, it breaks into large pieces that can be handled with bare hands.
A reflection from 1/8" or 1/4" mirror looks excellent from 1-2 feet away, however, at 10-25 feet (or more), a "fun house" effect begins to happen because the sheet is flexible (compared to glass that is very rigid). The quality of the reflection is entirely dependent on the flatness of the wall you mount to and the size of the mirror.
Use 1/8" mirror for small installations - 24" x 24" or smaller for a near-perfect close-up reflection. Typical applications include use in boats, campers, retail displays, and more where the viewer is very close to the mirror and risk of breakage is high. 1/8" thickness is also great for events with open tabletops, since you can lay the acrylic sheet on top of the tablecloth for a great look and safe, easy to clean surface.
Use 1/4" mirror for installation over 24" x 24".
Security Mirror in store: Use 1/4". At distances beginning 30-50 feet, the reflection will be distorted regardless of how flat the acrylic mirror is mounted. You may want to test 1 piece for this kind of installation.
Theater and Dance Rooms: Use 1/4". Keep in mind that the reflection will not be as crisp as glass mirrors offer, however, plexiglass mirror would be used for safety.
Clubs and Restaurants: Use 1/4" for safety and strength.
Mounting: If you use screws for mounting, you will get distortion in the reflection. You must use a plexiglass drill bit when drilling through plexiglass. Metal bits will crack the plastic material. Double face tape offers a secure and safe installation for sizes that will remain secure with the tape strength.
Water based Contact Adhesive - a permanent solution to a FLAT surface.
Cleaning: Use Brillianize or Novus products or soap and water for cleaning and scratch removal. Do not use window cleaners such as Windex or 409.
Also available is Lexan® polycarbonate mirror by special order. The advantage polycarbonate has over acrylic is that it will not break and can handle higher temperatures (250 F). This is good for police stations, psychiatric wards, prisons and other locations that have severely high breakage potential. Scratches do not come out of polycarbonate mirror at all, but can be removed from acrylic.
