The Peterlee Glass guide to ordering custom mirror glass

Wednesday 29th March, 2017


Everyone knows the huge difference a beautiful mirror can make to a room. Mirrors can make a space feel bigger by adding depth and bouncing light back into a room, but they can also add a sense of luxury to a decorative scheme.

This is especially true when it comes to custom-made mirror glass, which can be manufactured and cut, bespoke for your home.

Of course, ordering custom mirror glass isn’t as straightforward as nipping down to your nearest home furnishings store and picking a mirror up off the shelf. But with leading glass suppliers like Peterlee Glass, it can be a pretty easy and trouble-free process if you follow our simple how-to guide below…

Step 1: Choose the type of mirror you need

If you’re buying from a leading glass supplier like Peterlee Glass, you can be assured that the mirror glass you’ll receive is of the highest quality.

We use Pilkington mirror glass for a clear and brilliant appearance and we recommend a guage (or thickness) of 6mm. This ensures the optimum strength for your mirror and will safeguard against any distortion in the reflection caused by flex, which can be a problem with thinner mirror glass.

For large mirrors, or areas where breakage is a risk, such as in bathrooms, we strongly advise you consider safety backing for peace of mind.

Step 2: Choose your edge finish

We can supply your mirror glass with either ground or polished edges. A ground edge has a matte or satin finish, which reduces the reflectivity through the edge of the mirror, whereas a polished edge is fully polished, glossy and translucent.

The decision is entirely cosmetic, so simply choose whichever look you prefer.

You’ll also need to decide whether you would like a D edge “flat” polish or a bevelled edge.


Step 3: Decide how you will hang your mirror

There are three main options for hanging mirror glass:

  • J channels: These are generally made of aluminium and are drilled on to the walls. Two channels are used – one at the bottom and one at the top – and the mirror simply slots into the rails. The advantages are that this is a cost-effective and quick method of hanging a mirror, and it is simple to remove a broken or old mirror. The disadvantages are that not all walls are capable of supporting the weight. For stud walls, the channels need to be drilled on to the supports.

  • Adhesive: Specialist mirror adhesive can be used on surfaces that are non-porous. Walls must be completely flat for this option and two people are required for installation. The strength of mirror adhesive can be both an advantage and a disadvantage – once hung, the mirror will never budge. This can be a problem if you need to remove it at a later date!

  • Screws: For this option, we will pre-drill screw holes into your mirror. Again, if screwing to a stud wall, the supports will need to be located in order to fix the mirror securely. When hanging the mirror, it is important to make sure you don’t over-tighten the screws, as this can crack the mirror glass.

Step 4: Measure up

The next step is to measure up. This can be a fairly straight-forward process, but it’s important to be absolutely sure of your dimensions before you order. Keep in mind the old saying, “measure twice, cut once”.

Firstly, check your walls, skirting boards, floor or any other surfaces that will be in contact with the mirror are straight and level, using a spirit level. Skirting or flooring that isn’t straight will show up when the mirror is erected, so it’s a good idea to carry out any remedial work beforehand.

If your mirror is to sit flush between two walls, but the walls aren’t square, we can accommodate this when we cut the glass, but we’ll need to know exact measurements to get a perfect fit. Check whether your walls are square by measuring them at the top, in the middle and at the bottom.

When you have measured the exact space where your mirror glass will sit, take 2mm off to allow for tolerance.

If you plan on using J channels to hang your mirror, you’ll need to leave a tolerance of 20mm on the height to allow for the top channel.

If you are in any doubt about accurately measuring for your mirror, or for more complex measurements including cut-outs for sockets etc, get in touch with Peterlee Glass’s custom glass services. We can arrange for one of our surveyors to come out and measure up for you, taking all the worry out of your hands.
