    • FAQ

    A spy mirror is a special silver mirror with a thin coating on one side of a clear, extruded acrylic sheet. The mirror coating has a 15% light transmission. This makes it possible that some vision comes through the sheet.

    The setup for proper use is to use the spy mirror in a dark room with an observer on one side of the mirror and on the other side a light room with the observed person. The spy mirror sheets are not suitable for outdoor use and in wet conditions. The mirror coating is very vulnerable. As such, one should not apply any kind of tape to the mirror’s surface, even if it’s temporary. Removing the tape will damage the coating. It is possible to produce thicker spy mirror sheets or spy mirror sheets on other substrates. These sheets have a thin layer of PET-foil, this foil is suitable for in wet conditions.

    Stock spy mirror

    PyraSied has the spy mirror in stock in a thickness of 3mm in a silver colour. PyraSied also has a mirror made of polycarbonate. Polycarbonate mirrors are more impact resistant than acrylic mirrors.


    The spy mirror is often used for observations, but also for art installations, scientific applications and lighting fixtures. The mirror is absolutely not suitable for outside applications or humid conditions, because the foil is not water- and weather proof. The mirror coating is very vulnerable. As such, one should not apply any kind of tape to the mirror’s surface, even if it’s temporary. Removing the tape will damage the coating.  You should also avoid the use of any acid materials. See the FAQ for more information.

    Mirror acrylic is slightly flexible and must be attached to a flat surface for a good result. If this is not done properly, you will get a distorting mirror. The larger the sheet, the more likely it is to show some distortions.

    Common applications are: Spy mirror, magic mirror (infinite mirror, smart mirror), glazing, art pieces, protection of decors and art pieces. For inspiration, please take a look on our Acrylic Community.


    Sawing (circle- or table saw/jig saw), milling, laser-cutting, bonding and drilling. For more information about fabricating acrylics, please go to our fabrication page.

    Frequently Asked Questions
    Can I use spy mirrors for outdoor applications?

    No. The spy-mirror is absolutely not suitable for outside use or humid conditions, because the foil is not weather proof. The two-way mirror can be used for outdoor applications.

    What is the light transmission of the spy mirrors?


    Is it possible to add a scratch-resistant layer to the mirror sheet?

    Yes, however these sheets are not on stock. Ask our sales department for more information: sales@pyrasied.nl.

    What is the difference between a spy mirror and a two-way mirror?

    A spy mirror has a lower light transmission (15%) than two-way mirrors (+21%). The two-way mirrors are on stock in various colours and thicknesses, the spy mirror is only on stock in silver in 3mm.

    How do I clean the spy mirror?

    The mirrors can be cleaned with a soft non-woven cloth. You can use water with some detergent, household vinegar or cleaning-alcohol. PyraSied recommends to use Burnus antistatic cleaner or VuPlex. VuPlex gives a protective layer and removes visually small scratches. PyraSied can supply these multifunctional cleaners. You should never use Glassex, strong solvents, schotch-brite and other abrasive products.

    What should I do when I have scratches on the surface of the mirror?

    When the material has scratches, you can remove those by sanding the front side of the material with a grain 1200 (depending on the deepness of the scratch) followed by polishing the material with a soft cotton and a polishing agent.

    How do I install mirror sheets and which materials can I use?

    It is possible to attach the mirror with mirror holders, spacers or with sealant on a wall. (you can only do this once! When removing the mirror, the mirror film will be damaged). You should use an acid-free silicone sealant when attaching the mirror sheets to walls or other substrates. As the mirror sheets do expand and contract with temperature, the minimum thickness of the sealant layer is 2 mm behind the sheets. You can also use natural foam tape with a minimum thickness of 2mm.
    You can not use regular tape or anything acidic, even temporary.
