Bespoke mirrors in Cardiff
A safety-backed mirror has a film bonded across its back that holds the pieces together if the glass breaks, so fragments stay on the backing instead of falling or scattering. Some backing films are classified for impact under BS EN 12600, and the film is applied before fitting.
Large mirrors are usually fixed with mirror adhesive and supported at the base by a slim channel or clips while the adhesive cures and afterwards. Smaller mirrors can be screw-fixed through drilled holes with decorative caps, which also lets them be removed later.
Safety backing is a sensible choice wherever someone could fall or knock against a mirror, such as sliding wardrobe doors, full-height mirrors, children's rooms, gyms and dance studios. We recommend it at survey wherever the position or use of the room suggests it.
In bathrooms, good ventilation does more to protect a mirror than anything else, because steam and condensation reach the edges and backing. A heated demister pad behind the mirror keeps it clear after showers, but it needs wiring by a qualified electrician.

- Coast
- Cardiff is about 3 km from the coast or a tidal estuary, so salt air and wind-driven rain are worth planning for. Mirrors are fitted indoors, but salty, humid coastal air can still reach the silver backing through exposed edges, particularly in bathrooms and near entrances. Protected edges, a compatible adhesive and good ventilation all help prevent black edge corrosion.
- Daylight and sun
- In Cardiff the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.6 hours of daylight, rising to about 62° and 16.4 hours in midsummer. A mirror opposite or beside a window reflects daylight deeper into a room, which helps dark north-facing spaces through winter. Low direct sun on a large mirror can cause glare, so its position and any tint are worth considering.
- Access and setting
- Large mirrors for flats, salons and gyms often have to travel through narrow stairwells and small lifts, so walls may be covered in several panels with planned joints. Loading limits and building working hours can affect fitting times.
- Rules in Wales
- In Wales, Approved Document N covers safety glazing: safety glass is needed in and around doors and in low-level glazing where people could walk into it.

Clear silver mirror
Standard silver-coated float glass mirror, cut to size, suited to most rooms, wardrobes and wall mirrors where a true, neutral reflection is wanted.
Bespoke Mirrors in Cardiff: questions
Can I have a bespoke mirror in a bathroom?
Yes, provided the room is well ventilated and the mirror is protected from standing water. We use mirror that meets the relevant standard for internal use, bond it with a compatible adhesive and keep edges away from splashes where possible. A heated demister pad can keep part of the mirror clear, wired in by a qualified electrician.
How should I clean a mirror without damaging it?
Spray glass cleaner onto a soft, lint-free cloth rather than directly onto the mirror, then wipe and buff dry. That stops liquid running down and soaking into the bottom edge, which is where black edges usually start. Avoid abrasive pads and harsh chemical cleaners, and dry the edges after cleaning in bathrooms.
What is a safety-backed mirror and do I need one?
A safety-backed mirror has a film bonded across its back that holds the pieces together if the glass breaks. You should consider one wherever someone could knock or fall against the mirror, such as wardrobe doors, full-height mirrors, gyms, dance studios and children's rooms. We recommend it at survey when the position or use of the room calls for it.
Can a large mirror be fixed to plasterboard?
Often, yes, but it depends on the board, its fixings and the surface finish. Adhesive grips the paint or plaster layer, so flaky paint or weak skim can let go under the weight. We check the wall at survey and may add a base channel, mechanical fixings into studs, or a backing board to spread the load.
