Secondary glazing

Secondary glazing

Replacing your inefficient windows is one of the best home improvements you can make to reduce your energy bills and cut carbon emissions.

Most homeowners will look towards double glazing when replacing their old windows, but listed buildings and properties in Conservation Areas often won’t be granted permission.

This is where secondary glazing comes in, as it doesn’t change the external look of the property and instead a second pane is fitted on the inside of the first, with an air gap to heighten energy efficiency.

Of course, this isn’t as efficient as a double glazed unit but still stands to save homeowners plenty of money every year on their energy bills.

Secondary glazing has become much more popular in recent years, as it shares a lot of the same qualities as double glazing, but comes at a cheaper cost.

Benefits of secondary glazed windows

With secondary glazing in your home to replace single paned windows:

  • Reduce your heating bills

The two panes of glass will work together to lock heat in your home, ensuring you needn’t turn up the temperature to keep warm.

  • Add to your home’s security

As you would expect it’ll be tougher to break into a secondary glazed property, so you’ll have peace of mind and less worries of an insecure home.

  • Cut noise pollution that enters your home

In the same way heat is retained in your home, noise pollution is kept out. This is particularly beneficial if you live near a busy main road or traffic works.

  • Slash your home’s carbon footprint

Cutting carbon will make your property more environmentally friendly. This is done by reducing the workload of your boiler, therefore cutting fuel use.

The effectiveness of secondary glazing will be directly affected by the gap between the two panes of glass, normally recommended at 100mm. Sound insulation will also improve with the glass’ thickness.

How does double glazing work?

As a result, we usually have a long to do list comprising things that come together to make sure our home is comfortable with ambient temperature at the very top of the scale of preference. After all, no matter how greatly designed your furniture and home decor is, it probably would amount for nothing if the temperature is either too hot or too cold. Some of the most common ways we incorporate to make the temperature a lot more conducive and warm during the winter months is by installing air conditioning system or through top notch insulation materials, but the fact still remains that a lot of heat would escape through the doors and windows. And that’s exactly the use of double glazing. So how exactly does double glazing work?

Double glazing basically works by preventing the escape of air and trapping it between two panes of glass. It’s the trapped air which serves as an insulation barrier which delivers 3 major functions. First and foremost, it stops the escape of heat through the window as the barrier created insulates the room from varying air temperatures at both sides of the glazing unit. The second major function is the double glazing works to keep down noise pollution coming from outside. While the third major function of double glazing I the fact that it helps minimize condensation which usually occurs on the single glazed windows’ inside as the cold outside air works to cool the warm air inside the house. When you install a double glazing window, the insulation barrier generated will work to stop the air temperature transmission which ultimately helps prevent the occurrence of condensation.
