Depending on the space between the acrylic sheet and the glass, secondary glazing can provide up to 26 dB of sound reduction. For this calculation, a 4 mm thick acrylic sheet was used.
Because plastics are strong, impact resistant and easy to work with, they are used for many different tasks. The panel will stay beautiful for a long time and is therefore very suitable as a plastic window for a door, a garden shed or a garden door. However, these impact-resistant sheets can also be used for other purposes, such as model houses, wine cabinets and boat windows. Below we have listed some popular applications for you.

Plastic windows are more impact resistant than glass and do not break easily even under (very) high loads. Another great advantage of plastic windows is that the material is UV-resistant. This is good for a window material that is exposed to large amounts of ultraviolet radiation.

The insulation value is expressed by the U-value. It depends on the thickness of the material. Here, the lower the value, the better the insulation. For acrylic, polycarbonate and glass this is as follows:
Plastic is often chosen as an alternative to normal glass. To the naked eye, plastic windows are just as transparent as normal glass. Plastic windows are very pressure resistant and can be used for applications such as aquariums and even police signs.
Plasticsheetsshop.co.uk offers a wide range of acrylic and polycarbonate windows, both of which are good substitutes for glass. Choose between a crystal clear version or a beautiful tint for a stylish effect. This way you can be sure that you are making a durable, high-quality and also price-conscious choice. Acrylic is a well-known name and is stronger than normal glass. Polycarbonate, on the other hand, is a little less well known but much stronger than acrylic.

Acrylic and polycarbonate are – as you can see from the product recommendations below – the most suitable products for use as windows. Both materials are translucent and stronger than normal glass. Polycarbonate is the front runner and can even be described as foolproof due to its high impact resistance. With both materials, you also have the choice of tinted versions, which can be used to create a special effect. However, tinted acrylic is also often chosen for functional reasons. For example, grey tinted acrylic is a commonly chosen material for the windows of a wine cabinet!
Cleaning acrylic or polycarbonate with harsh detergents will damage the sheets. This can make your secondary glazing look dull. Check out our blog on how to clean acrylic or how to clean polycarbonate.

Plastic is a suitable replacement for normal glass. Thanks to the high strength of these panels and their high light transmission, you can combine the advantages of glass with the convenient properties of plastic. An ideal combination that can be used for many purposes. For example, if you have glass windows in your shed, a shovel is enough to break the window. Plastic windows, on the other hand, are very stable and robust. For applications that require a less breakable material than regular glass, but still need the same transparency, plastic windows are an ideal solution.
We are also happy to laser or saw the window to any size and shape you require. This way you can be sure that the new panel will fit your window exactly. In addition, all our orders are delivered to you securely packaged to minimise the risk of damage to the window during transit.
A glass window breaks more easily than a plastic window. In addition, a plastic window is just as translucent and often cheaper.
Single-glazing (4 mm) → U-value 5.7 W/(m^2*K) Double glazing (standard) → U-value 2.8 W/(m^2*K) Combination single-glazing (4 mm) with secondary glazing (4 mm acrylic) → U-value 2.7 W/(m^2*K) Combination single-glazing (4 mm) with secondary glazing (4 mm polycarbonate) → U-value 2.8 W/(m^2*K)
We have created a handy step-by-step guide explaining step-by-step how to fit secondary glazing on the inside of a window.
