The Importance of Double-Glazing
Every home can be made more efficient in one way or another, but one way this can be done easily is through the installation of glazing throughout the home – double or secondary.
It is believed that 18% of heat in an uninsulated home is lost through the windows. This results in higher bills, higher CO2 emissions and other issues such as condensation.
Single glazing windows are notorious for being pool insulators. The single panel easily brings the cold in from the outside, reducing the inside temperature and requiring a greater amount of energy to create and maintain a comfortable living temperature.
Consisting of two glass panels sandwiched between an inner and outer frame, double glazing is a perfect upgrade from single glazing. The space between the glass panels is normally filled with Argon gas creating heat insulation as well as an effective noise barrier.
Windows can be tested and awarded in a similar way to boilers and other domestic appliances and are awarded with an Energy Efficiency Rating. A scheme provided by the BRFC applies ratings from A-G based on the windows’ thermal efficiency – with ‘A’ being the best.
Double-glazed windows can also help reduce damp in a property by reducing the amount of condensation on the glass. The internal glass panels are at a temperature closer to that of the inside room, reducing the effect of internal air reaching it’s dew point and depositing the water on the coldest object – normally the window.
As a long term investment, windows will not pay for themselves in energy bills, however, they do help create a cosier, quieter and overall more comfortable environment. Not only do they help raise the value of a home and it’s aesthetic, they can also offer a better quality of life – those in a happy home tend to be happier in themselves.
Secondary glazing is an equally effective method but costs less and involves a single glass panel being applied over the original unit. This helps reduce heat loss and is a good alternative for buildings that require planning permission as none is needed for the addition of the second pane.
uPVC is not the only option available. Be sure to opt for a material that suits the amount of maintenance the building requires and the size of the budget.. Wooden frames require more attention while composite fames are weatherproof and long-lasting. Living in a conservation area? Keep the original look of the property by using timber frames.
