Are Double Glazed Windows Worth it?

What is double glazing

What are double-glazed windows?

Double-glazed windows are basically two panes of glass place together with a vacuum in between. The glass itself helps to insulate your home, but the key is the trapped air because air temperature cannot penetrate a vacuum so bounces back. This means the heat is kept in your home in winter and the heat is kept out of your home in summer. Sometimes the vacuum can be filled with argon or nitrogen. These slow-moving gases are so dense that they will reduce the transfer of heat out of your home even further. You can also choose to place a piece of laminate between the two panes of glass to help increase the strength and safety of your windows. This thin membrane also cuts down any UV radiation coming through your windows. Find out more about what double glazing is here.

How can double glazing benefit my home?

According to the Energy Saving Trust, by installing double glazing, a single-glazed detached home could save up to £110 on energy in a single year. In addition to the potential financial payback, installing double glazing can deliver several other benefits to your home which are well worth considering. Double glazing all the windows in your home can be a huge job and an expensive investment but the savings you may make in the long term may make it worth it. Lets take a look.

The technical definition of condensation is:

The process that gas or vapour transforms into a liquid. If an object’s temperature, like glass, drops under the ‘dew point’ temperature of the surrounding air’s given relative humidity, water vapour from the air condenses into droplets of water on its surface.

The ‘dew point’ changes according to the volume of water in the air ( humidity). In muggy conditions, condensation happens at higher temperatures. In colder environments, condensation occurs even though there is low humidity present in the atmosphere. If condensation has formed between the two panes of glass on your double glazed window, you have a major problem.

Condensation indicates that the seal that surrounds the two panes of glass has sprung a leak. In turn, this means that the gas cavity between the window panes is not sealed. If this has happened, then you must replace your existing double glazing straight away.

Heat loss through windows:

Research has proven that up to 18% of heat is lost through the windows. This means if you have single glazed windows your bills will cost more than they need too, you will be damaging the environment more than necessary and you will have to cope with additional problems such as condensation in your home and noise from outside.

My double-glazing is out of style – I want to modernise!

Beauty is in the eye of the beholder and so while some people love their uPVC windows, you can still modernise your windows by glass design, handles, and even frame colour.

This is a decision that we can’t really help with, but we are here to help along the way.

My double-glazing is falling to pieces!

This is one of the most compelling reasons to replace your double-glazing – if they are rotting then it is time to get them replaced! Wood rot not only looks bad, it can actually make the windows unsafe and much like the ill-fitting windows, air can rush through any gaps resulting in your heating system having to work harder during the winter months.


So Is Double Glazing Worth the Cost?

Double glazing should be viewed as a long term investment in your home and over time you could see significant savings on your energy bills. The installation will create a warmer, quieter environment ensuring a better quality of life whilst increasing the resale and aesthetic value of your home.
