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.
