## Overview

This 3mm Two-Way/See-Thru Mirror Acrylic Sheet combines a semi-transparent aluminium film with a durable acrylic base, delivering a lightweight, shatterproof alternative to traditional glass mirrors. Perfect for privacy, surveillance, and creative smart mirror projects, it offers superior impact resistance and easy customization across 15 sizes, making it the go-to choice for professionals seeking safety and style.

## 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.

## Questions & Answers

**Q: can this be laser cut?**
A: The only main issue with laser cutting is the heat which might deform the edges and distort the mirror. What shape do you want to cut it to? We would tend to use a flatbed router cnc machine to cut this with a clearcut router bit that gives a polished look, not high polish though but a nice edge, usually edges are covered in a window frame etc so edge finish isn't usually an issue. You can email us with details sales@esupplyline.com or 01953 711 881. We also stock this in 6mm. The brand is Plaskolite which is the manufacturer that has that image used in the listing, I don't think it specifies the brand anywhere so check with suppliers what brand they are supplying.

**Q: If i use this in a large size and place a small monitor behind at full brightness in a dark room would i basically see the tv area through the mirror?**
A: Yes, you will be able to see the display behind the mirror even in daylight, but it is better in the dark.
 I used this product to build a magic mirror and the results was better than I had hoped for.

**Q: This might be a stupid question, but does it matter which way round you install this mirror?**
A: Yes it does, one side is coated and is normally on the inside of where you are using it to protect it, the other side is just the acrylic, one way to tell which is which is that the coated side due to how delicate it is the protective film is barely hanging on, you can pretty much blow it off, bit of a pain when sawing or cnc cutting it, or storing it because if stored standing up the protective film can just fall off under gravity, the face of the product is just protective film onto clear acrylic which is stuck on much better, there is an obvious difference between the 2 and I would use that on the side you use to protect the product. Cleaning acrylic can be a pain as even some cloths can slightly scratch it, here when I clean a piece to check anything I liberally spray with furniture polish, use a typical duster and very lightly wipe over it rapidly back and forth until the polish has pretty much gone, all clean and no marks.

**Q: Can it stick on wall?**
A: As Russ has said, it can but if you are just going to use it as a single sided mirror to fix to a wall or anything else then that is available https://www.amazon.co.uk/dp/B0733PH36V it can be supplied with double sided on the rear too for an additional cost.

### ⭐⭐⭐⭐ Cheap as chips and works a treat
*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
