Double Or Secondary Glazing?
If you want a more energy efficient home and reduced heating costs then proper home insulation is essential. One of the first things to consider is the windows. Approximately 30% of your home’s total heat loss is through your windows. There are two energy efficient alternatives available: double and secondary glazing.
Here’s a comparison guide to help you decide which one would be right for your property.
Double Glazing
Double glazing involves a complete window structure comprising of two panes of glass separated by an air gap. This acts as an insulating barrier to prevent heat loss and condensation build-up. Double glazing is not only incredibly energy efficient but it will also drastically reduce your heating costs. It’s more secure than single paned glass and has high UV protection and noise reduction properties.
Secondary Glazing
Secondary glazing consists of a single frame system that is installed inside the existing window frames creating a narrow gap between the two. It is a cost effective way of making your home more energy efficient and secure without changing the exterior look of your property, and is therefore a good choice for listed and heritage properties.
Cost
Double glazing is far more expensive than secondary glazing. This is because the entire window frame system needs to be dismantled and replaced. Secondary glazing is quicker and easier to install as it is simply added to the existing windows, therefore the entire process is far less disruptive than double glazing installation.
Thermal Properties
Both systems will improve energy efficiency although the superb insulation properties of double glazing are hard to beat. Bear in mind the initial cost of double glazing will show its worth in your future heating bills.
Planning Permission
Double glazing is now available in stunning period framed replicas, however if you wish to install them in a listed building you’ll need planning permission. Secondary glazing doesn’t need planning permission, even in period properties.
Cleaning
Double glazing is easy to clean, both inside and out, whereas the gap between the two glass panes in secondary glazing make it awkward to clean properly and you’re also faced with cleaning four panes, not two.
Whatever your choice, both systems do their job well. They are good sound barriers and they’ll not only keep your home warmer, but also more secure. Ultimately the decision is down to budget and personal taste.
