## Description

Acrylic mirror sheet or perspex mirror is an excellent alternative to glass mirrors. Its impact strength is around 10 times greater, more flexible, shatter-proof and safer than traditional glass in equal thickness. Suitable for a wide range of applications due to their excellent impact resistance and light weight. Mirrored acrylic can be cut to limitless shapes and sizes. Can be drilled and glued (using acrylic mirror adhesive) or screwed in place very easily. As mirrored acrylic is safe to handle it can be used without any prior training unlike traditional glass mirror which requires extremely careful handling and storing. The flexibility and low weight of extruded acrylic mirror along with itsely high impact strength makes it the ideal solution in both industrial and domestic settings. Supplied with a protective plastic film on both side. Not as rigid as glass mirror and, as with all acrylic mirror, visual distortion can occur. Correct installation and sufficient material thickness can reduce visual distortion but will not completely eliminate it. As some adhesives attack the mirrored surface, we recommend using our Evo-Stik acrylic mirror adhesive. Contact us on: 0203 667 7067 / info@crestarltd.com

Review: Perfect piece of priduct - Perfect for a test project. Piece was cleanly cut and I only needed to slightly trim to what I needed. If custom sizes were available, would definitely order again.
Review: Dont buy mirror film get this! more expensive but great quality. - Messed around with mirror film from a few suppliers before buying this. There is no comparison. Even if the film is fitted with no bubbles etc its just not a great reflection, inconsistent, shows up any imperfection in the glass etc and if you are thinking of using mirror film on plastic or acrylic sheets forget it they dont work!. This however is perfectly made and works great for a Smart Mirror which is what i bought it for. My wife is the ultimate cynic when it comes to diy tech (i have tried and failed many times to impress her with my tech ideas) but even she admitted that this was a good mirror and adding the tablet behind the glass to create a Smart Mirror with appointments birthdays etc and fitting it into a cheap white Ikea picture frame made it look a professional job. Highly recommended and finally managed to buy something that does what it says rather than cheap mirror film!

## Features

- 3mm Two Way / See-Thru Mirror Acrylic Sheet. For custom sizes, please contact us for a quote.
- The two-way mirror also known as See-Thru Mirror, has a semi-transparent film of aluminium deposited on an acrylic substrate which allows a percentage of incident light to pass through while reflecting the remainder. When illuminated, the side with the light source will be reflective and the opposite (darkened) side will be transparent.
- Made from acrylic, it benefits from the typical attributes associated with other acrylic sheets including being lightweight and shatterproof and therefore an option to be used where safety is paramount such as around children and animals.
- he material can be used for a wide range of applications including monitoring and surveillance operations including in stores, post offices, banks, correctional and psychiatric institutions, hospitals to casinos. The two-way mirror is also commonly used to create infinity lights and multiple image devices.
- Full range of sizes and colours available. Please contact us for more information.

*by M***K on 11 November 2017*

I picked this up to make myself a diy teleprompter and it was great for what I needed. It does have a slight blue hue which you will need to colour correct if you are filming through it. HAppy to answer any questions you might have
