Energy efficient glass

A staggering 26% of all domestic heat loss escapes through the windows*. Installing energy efficient windows in your property can save you up to 28% per year on your heating bills compared to traditional windows and frames.

Window Energy rating are there to explain how energy efficient your windows are. The rating system is founded on ratings of A-G. Naturally A rated glass is the most energy efficient glass. All windows and doors that we install in your property are able to achieve up to A rated energy efficiency. We take great care in our work and have chosen the Profile 22 system for our replacement upvc windows to go with our quality ideals. We are a Fensa registered installer

Benefits of our energy rated windows

• Reduced energy costs: replacing all single-glazed windows with B-rated double glazing could save you around £165 per year on your property energy bills.
• A smaller carbon footprint: by using less fuel, you’ll generate less of the carbon dioxide that leads to global warming – typically, 680kg a year.
• A more comfortable property: energy-efficient glazing reduces heat loss through windows and means fewer draughts and cold spots.
• Peace and quiet: as well as keeping the heat in, energy efficient-windows insulate your property against outside noise.
• Reduced condensation: energy-efficient glazing reduces condensation build-up on the inside of windows.

“A” rated being the highest rating available

“B” rated being in between

“C” rated windows offered as standard

How is a window energy rating calculated?

A window’s WER is determined by a formula which takes into account three factors: Available solar heat gains (window g-value), i.e. how much free heat and light is captured from the sun, minus thermal losses (window u-value) i.e how well heat is retained and radiated back into the property, and air leakage (L factor) i.e the amount of heat that is lost due to air penetration such as draughts and cold spots. WERs = window g-value - (window u-value + L factor) The resulting numerical value (known as an energy index) is then placed into a band on an A-G scale consistent with other energy performance labels already familiar to the consumer.
