In this blog, we compare two of our most popular glass replacement plastics: plexiglass and polycarbonate, to help you make the right choice for your project.
Plexiglass – the versatile glass substitute
Plexiglass, also known as acrylic, is one of the most commonly used plastics as a lightweight and impact-resistant alternative to glass.
Key properties of plexiglass:
- Strong and light: thirty times more impact-resistant than glass and half the weight.
- Cost-effective: cheaper than traditional glass.
- Workable: ideal for DIY enthusiasts and professionals, easy to saw, mill, polish or glue.
- UV and weather resistant: suitable for outdoor use, such as boat windows or patio roofs.
- High light transmission: allows more light through than ordinary glass, ideal for indoor applications such as bathrooms or interiors.
Common uses of plexiglass:
- Windows and display cases
- Shower screens and partition panels
- Housings for audio and television equipment
- Aquariums for animal enclosures
- Corona screens for shops, offices and public spaces
Thanks to this versatility, plexiglass is ideal for interior design projects, advertising and protective applications.
Polycarbonate – unbeatable impact resistance
Polycarbonate, also known under the brand name Lexan, is an ultra-strong glass substitute that is mainly used when safety and durability are crucial.
Key properties of polycarbonate:
- Extremely impact-resistant: up to 250 times stronger than plexiglass.
- Lightweight: 50% lighter than glass, yet extremely robust.
- Heat resistant: resistant to high temperatures and UV radiation.
- Chemically resistant and electrically insulating: suitable for industrial applications.
- Workable: easy to saw, mill, drill and glue.
Common uses of polycarbonate:
- Safety glass and glazing for bus shelters, bicycle sheds or shop windows
- Helmets, helmet visors and police shields
- Safety goggles and machine protection
- Greenhouses and screens
- CDs, DVDs and other sturdy cases
Polycarbonate is therefore ideal for safe and robust applications, both indoors and outdoors.
Should you choose plexiglass or polycarbonate?
The choice depends on your project:
- Choose plexiglass for applications where light, aesthetic and easily workable sheets are required, such as interiors, decoration or displays.
- Choose polycarbonate for projects where impact resistance, safety and durability are key, such as in construction, industry or public spaces.
