What is retrofit double glazing?

Retrofit double glazing means replacing your existing single glazing with double glazed units within your existing window or door frames. We can retrofit existing timber, aluminium and steel joinery. The process is quick and unobtrusive.

 

What are the benefits of double glazing?

The benefits of double glazing include:

  • Warmer in winter through improved heat retention
  • Cooler in summer due to reduced solar gain
  • Reduced heat loss means lower heating costs
  • External noise reduction
  • Reduced condensation, mould, mildew and rot to timber window frames
  • A safer, more secure home as double glazed windows are much harder for intruders to break in through, especially if you add laminated, toughened or safety glass
  • Improved resale value of your home

 

How long does it take to double glaze a house?

This will vary depending on whether your existing frames are timber or aluminium, how many windows in your home, whether any of it is second story etc… The whole process is done onsite. Aluminium retrofit double glazing for your home could take as little as a few days and around a week for wooden joinery. Whether you want to double glaze your whole home or a few rooms, we can provide you with a free quote and an indication of how long it will likely take.

Any windows taken out are replaced the same day so your home is still safe and secure at the end of each day.

 

What are insert windows?

Whether it’s because you no longer want to maintain wooden windows, your old windows don’t service your needs anymore, or because your existing joinery is beyond repair, insert windows are a quick and cost effective option, with lots of benefits. Your existing wooden frames remain, and new windows are fitted directly into the same space that your old windows are removed from. Your new windows can be made to any configuration. There is no need to change anything else. No need for consent, no need for a builder, no need to change any of the internal or external walls.

 

What is Low E glass?

Low E glass has a variety of different names depending on the supplier, eg; also known as Planitherm XN. Low E stands for ‘low emissivity’. Low E glass increases the thermal efficiency of your windows because it reflects more heat and solar rays than standard glass which means your house is warmer in winter as the amount of heat lost through your glass is reduced, and cooler in summer because the amount of heat and solar radiation entering through your glass is also reduced.

In addition to Low E glass, you also have the option to include Argon gas and thermal spacers for even better thermal efficiency.

We are happy to discuss all the various glass options with you and determine what will best suit your needs and budget.

 

Some Statistics

  • Standard double glazing increases thermal efficiency (i.e. reduces heat loss) by 50% compared to single glazing
  • Low E glass increases thermal efficiency by 77% compared to single glazing.
  • Low E glass increases thermal efficiency by 54% compared with standard double glazing.

A modern insulated house that meets 2009 Building Code loses up to 45% of its internal heat through single glazing. Standard double glazing can reduce this heat loss by up to 33%, and less than 28% if Low E glass is fitted.
