Energy Saving Glass From Harrogate Windows

On average 25% or 30% of heat from a home can be lost through the windows. Just one single pane of glass, unprotected, can lose up to ten times more heat than an insulated wall of the same size. With this in mind, windows now come with an energy rating system similar to boilers or washing machines etc.


Windows are rated "A" to "G" based on the thermal efficiency of the windows. Windows rated "A" are the most energy efficient and those rated "G" the least; a rating of at least "C" is required for "Energy Saving Recommended" certification.

This window rating system takes into account heat losses through the glass and through the frame and allows comparisons between products.

The most common form of energy efficient window is the double glazed window which consists of two panes of glass separated by sealed space of of argon gas up to 20mm wide.

Double glazing can reduce heat loss in the home by up to 50%, and reduce carbon dioxide (CO2) emissions by over 700kg.

Your heating bills can also be reduced by over £100 per annum for a typical household.
