Different types of Plastic Double Glazing

Plastic Double Glazing isn’t just a second sheet over your window, it can come in different forms depending on your needs. 



Acrylic Secondary Glazing

The easiest to install and flexible for different windows, Acrylic Secondary Glazing gives your windows an air-tight seal, even on uneven wooden frames. Acrylic Glazing Sheets can even be used on interior windows if you require soundproofing from living near a busy road or noisy area.

One of the easiest and cost effective secondary glazing is the Secondary Double Glazing edge strip. You can find thicker Glazing Strips by searching at the top.

Magnetic Secondary Glazing

For a more permanent option, Secondary Magnetic Glazing creates a firm and air-tight seal with an opening for Acrylic Glazing Sheets to be removed and replaced over time. With its strong protection against the weather, it is the ideal choice for temporary windows on building sites too.

For a DIY enthusiast, Acrylic Secondary Glazing is a simple installation as it doesn’t require a specialist tradesman and is much cheaper to install that glass glazing. Acrylic will not shatter like glass too and is much lighter for travelling.

Acrylic Glazing Sheets

Durable Plastic Sheeting, Acrylic Glazing Sheets are primarily used windows and car panel replacements. It’s thermoformability (Protection against the cold) and strength make it suitable for interior car parts like trim rings, speaker grilles and race car switch panels. When under extreme conditions, a Plastic Sheet mould makes it perfect for race car body parts.

They’re also made for the Magnetic Secondary Glazing, with sheets that easily fit into place. Sheet Plastics offers a bespoke design service to make your exact requirement.

What is Secondary Glazing?

Secondary Glazing is a protective layer that fits over a window to provide benefits like thermal insulation and noise reduction. Acrylic Sheets are the typical choice for Secondary Glazing in buildings. 

It is also used as increased security for break ins, creating a secondary barrier for any intruders. To reduce condensation build up and potential mold in public and shared buildings. This is becoming almost essential in specialist heritage buildings that need some help to stay cost effective on rainy days. 

How to Clean Plastic Windows

The best way to clean Acrylic Plastic Windows is by using a basin of warm soapy water (Or washing up liquid) and a soft cloth or sponge to wipe down the window. Do not use a scouring pad or sprays as they can scratch the plastic and remove the glossy see through look.
