Heat gains come from heating systems, the sun’s warmth and internal gains from things like appliances and body heat. Heat losses occur through conduction in the walls, floor, roof, windows and doors or via ventilation in the form of air leakage.

Reducing heat loss reduces heating needs, and hence bills. This can be done by improving the insulation of your building’s envelope, improving air tightness or turning down the thermostat.

The diagram and the photo shows what the Energy & Efficiency Rating catergories are and the Heat Loss from a house before and after double glazing seen through a thermal camera.As you can see the heat loss is dramatically reduced.

All our windows are A rated as standard,we only use and fit top quality from leading manufacturers.
