What Is Secondary Glazing and How Effective Is It?

what is secondary glazing

When it comes to choosing the right window glazing for your home, there are a wide variety of options to consider each of which improves energy efficiency, maintains privacy and increases security. So which one should you pick?

We’ve previously discussed What Is Double Glazing and Why Is It Important? In this article, we’ll look at the unique benefits of secondary glazing.

What Is Secondary Glazing?

Double glazed windows have two sheets of glass with a gap between them. Secondary glazing works by fitting a slim window unit over your existing windows to provide an extra layer of insulation. This means secondary panes are attached to existing single-paned windows from the inside. 

Which Type of Property Is Secondary Glazing Suited To?

If your property is a listed building or in a conservation area there are probably restrictions on what you can do to your windows. If you’re not able to replace the windows, secondary glazing is an excellent solution.

The slim sightlines of secondary glazed window frames don’t impose on the overall look of your home’s original windows. So this simple and elegant method is perfect for traditional timber window appearances — or for anyone who lives in an older property or conservation area and who can’t install modern uPVC double glazing.

Secondary frames are also available in a range of different colours and woodgrain effects. So you can match the existing look of your property seamlessly and add to your home’s energy efficiency without sacrificing the original features.

How Effective Is Secondary Glazing?

Secondary glazing is ideal for listed properties and conservation areas. Its improved energy efficiency will reduce heat loss in your home to save you money on bills. Secondary glazing is also a fantastic option to reduce noise pollution as the two different panes of glass act as independent barriers to the transmission of noise.

Furthermore, as there is no seal on secondary glazing, there’s no pressure difference between the inside and outside of the window so the glass can’t bow inwards or outwards. 

How Much Does New Secondary Glazing Cost?

Secondary glazing is the most cost-effective alternative to double or triple glazing — so it is ideal for homeowners with a limited budget and works wonders for your heating bills.
