Mirrors in plastic are impact-resistant, splinter-free and lightweight alternatives to traditional glass mirrors. They are ideal for children's rooms, nurseries, gyms, retail fit-outs and places where safety and low weight matter. In this guide you get an overview of advantages, applications and installation – so you can choose the right plastic mirror for your project.
Why should I choose a mirror in plastic?
A mirror in plastic is a safe and lightweight alternative to traditional glass mirrors. Instead of glass, the mirror is made from acrylic plastic with a reflective coating. This means the mirror is considerably more impact-resistant and does not splinter if it breaks. That makes plastic mirrors an obvious choice in rooms where safety, low weight and flexible installation are important.

What is a mirror in plastic?
A mirror in plastic is usually made from acrylic (PMMA) with a reflective coating applied to the back. The result is a lightweight, robust mirror sheet that can be supplied to measure. Compared with glass, plastic mirrors weigh considerably less (around half the weight of glass) and are easier to work with. They can be cut, drilled and installed with ordinary tools – with no risk of dangerous glass splinters.
Advantages of a mirror in plastic
Impact-resistant and splinter-free:
Plastic mirrors do not shatter like glass and are therefore considerably safer in children's rooms, nurseries, gyms and public environments. Even if the mirror is damaged, it does not scatter splinters everywhere.
Low weight:
Mirrors in plastic weigh around half as much as glass mirrors, making them easier to transport, handle and install – even on lightweight structures such as plasterboard walls.
Can be cut to measure:
Plastic mirror sheets can be adapted exactly to your project – whether it is a whole wall, an alcove or a bespoke solution. We offer cut-to-size.
Easy installation:
Plastic mirrors can be installed with mounting adhesive, silicone or heavy-duty tape depending on the substrate. No need for special fittings or a professional fitter.
Design options:
Available in classic mirror as well as bronze, grey and other shades, giving more interior design options.
Safety for children:
Plastic mirrors are recommended in all environments where children are present – nurseries, schools, children's rooms and play areas.
When is a mirror in plastic the right choice?
Choose a mirror in plastic if:
- Safety matters – for example with children, the elderly or vulnerable settings
- The mirror will be installed on a lightweight structure (plasterboard, plywood)
- You want a solution with no risk of splinters
- The mirror will be used in nurseries, schools or activity rooms
- You want special measurements or unusual shapes
- The weight of glass mirrors is a problem
For bathrooms and places with very high heat or humidity, ensure correct installation and ventilation.
Are there any disadvantages to a mirror in plastic?
- Scratch resistance: plastic mirrors are more prone to scratching than glass mirrors – the surface should be cleaned with a soft cloth and mild cleaners
- Reflection quality: very good, but in some cases can be slightly less sharp than a traditional glass mirror, especially in very large formats
- Price: plastic mirrors can be slightly more expensive than standard glass mirrors in small sizes, but the price difference disappears with custom measurements
How to install a mirror in plastic
Correct installation is decisive for long-term durability:
- Substrate: make sure the substrate is completely flat – unevenness can cause distortion
- Adhesive choice: use acid-free silicone or a suitable mounting adhesive – ordinary silicone can attack acrylic
- Pressure and stress: avoid stress in the sheet during installation – let the adhesive set without pressure
- Protective film: remove the protective film only when installation is complete
- Distance from edges: for screw mounting, always drill holes at least 2 x the sheet thickness from the edge
For large mirrors, a combination of adhesive and mechanical fixing (rails or fittings) is recommended as extra security.
Maintaining mirrors in plastic
Plastic mirrors require slightly gentler cleaning than glass:
- Use lukewarm water and mild washing-up liquid
- Use soft microfibre cloths – never scouring pads or steel wool
- Avoid cleaners containing ammonia, acetone or petrol
- Always dry with a clean, soft cloth to avoid streaks
- Do not use window cleaner containing alcohol
With correct maintenance, plastic mirrors retain their clarity for many years.

Frequently asked questions
Here are answers to the most common questions about mirrors in plastic.
Is a mirror in plastic safe?
Yes. It is considerably more impact-resistant and splinter-free than glass. Even if it breaks, it does not shatter into dangerous shards. That is why it is the preferred choice in nurseries, gyms and children's rooms.
Can I have the mirror cut to measure?
Yes. A mirror in plastic can be supplied to exact measurements (cut-to-size) – whether rectangular, square or a special shape.
Can a mirror in plastic be used outdoors?
It can be used in sheltered areas (covered patios, carports, entrances), but should not be exposed to harsh weather without correct installation and protection.
How thick should a plastic mirror be?
For smaller mirrors (up to 50x50 cm), 2–3 mm is sufficient. For larger mirrors (up to 1x2 m), 4–5 mm is recommended. For wall-covering mirrors, 5–6 mm with extra fixing is recommended.
Can plastic mirrors be used in bathrooms?
Yes. Plastic mirrors withstand humidity and condensation better than many glass mirrors, but ensure good ventilation and use acid-free silicone during installation.
How long do plastic mirrors last?
With correct maintenance, plastic mirrors last 15–20+ years. The reflective coating is protected on the back and is unaffected by normal use.
