Whether you’re looking to replace the windows in your home or you want to repair shed or greenhouse windows, it can be difficult to choose traditional between glass or acrylic. Both have their advantages, but more and more people are turning to Perspex as an alternative. Here are some of the benefits of using plastic glazing instead of glass windows in and around your home.

Better optical quality

One of the main benefits of using acrylic instead of glass is that the optical properties are superior, particularly for thicker sheets. This means they let more light into the room. So when it comes to windows, this means you can benefit from an extra 10% of light transmittance compared to glass, resulting in clearer visibility. When working with thicker panes of glass, the material can develop a cloudy or milky quality, or have a green hue to it. However, acrylic maintains the same visibility regardless of the thickness of the sheet and remains clear.

Increased durability

Acrylic is 17 times stronger than glass, this makes it virtually unbreakable and is shatterproof. So, if it does break it will just separate into large, blunt shards rather than hundreds of pieces. So it’s ideal for homes with kids and pets, as you can rest assured that they’ll be safe even if the glazing gets broken. A ball that would shatter a pane of glass in seconds would just bounce off an acrylic window. Glass shatters very easily and is an extremely hazardous material when it’s broken. By using acrylic, it removes this risk and will give you peace of mind.

Lower density

Acrylic has a lower density than standard glass, so it’s not only cheaper to produce and transport, but it’s also more lightweight. This adds to its benefits by making it easier to work with and install. Acrylic has half the density of glass and is more flexible, so it’s more impact resistant. This quality makes it easier to cut than glass too – it can be cut using just a scoring knife for thinner sheets, or a regular hand saw. This is particularly useful for windows which are an unusual shape, as acrylic can be cut really easily to virtually any shape or size.

Higher insulation

When repairing or replacing glazing within the home, insulation is high on the list of priorities. Acrylic is 20 per cent more efficient at reducing temperature flux compared to glass. This means cool or warm air from the outside can’t penetrate as easily. Not only does this help to make the temperature indoors more comfortable, and regulated but it also saves you money on heating bills as well.

Maintains its appearance

The misconception about acrylic is that it will yellow and turn brittle over time. While this may be true of cheaper plastics, acrylic maintains its quality and appearance for many years. In fact, this can be seen in applications such as aeroplane windows. These windows are made from clear acrylic – when looked after, acrylic stays looking good as new regardless of age or exposure to the elements.
