Many of us have seen the visual effect of an old glazing unit breaking down. Misted panes, condensation between the glass or even frost inside the unit during Winter! These are all unsightly, but what effect could it be having on the running cost of your home?
Double glazing works by creating an airtight layer of gas between the layers of glass, creating a layer of insulation between the outside and your home. When the seals break down over time, the insulation properties of the unit are lost. In fact, the effect on the U-value of the window breaking down can be extreme, for example, an A+ rated double glazed unit would have a U-value of around 1.1, but this same unit broken down could be closer to the U-value of a single glazed unit of around 5!
So what does this mean to you? Well... The Energy Saving Trust states that having A-rated windows could save you up to £160 a year on your gas central heating bill, this figure could quadruple using electric heating. Over the years this figure adds up, combined with the loss of sound insulation, this can have a huge effect on you and your family.
For a fraction of the cost of replacing the whole window/frames we can replace just the double glazed glass unit.
Call us or send us a message with the approximate size of the glass that has failed and we will give you a quote the same day.
