Why should we retrofit our windows and doors with double glazing?

25 Jun Why should we retrofit our windows and doors with double glazing?

From a point of view of energy optimizing your aging home, the necessity for using double glazing windows or doors is a foregone conclusion. Statistics show almost 15% – 25% of heat is lost (or gained as the case may be) through glass doors and windows. Other useful features of double glazing windows and doors are better safety, energy savings, better acoustic properties, style & design, attractive glasses & frames of modern material. The last but not the least important feature is that it is easy to install.

The Resistance to heat transfer is measured by the R value which is about 1 in single pane glass. This improves to about 7 in the case of Double Glazing saving quite a lot of Thermal Energy in the winter and also considerable electricity in the summer.
