Double glazed windows utilize two separate pieces of glass, separated by a vacuum. The vacuum layer acts as an insulative barrier. The glass used can be laminated or UV tinted, but is otherwise similar to the glass used in single glazed windows. In some instances double glazed windows can be up to 100% more efficient than a single glazed equivalent.

The most obvious benefit to be gained from double glazed windows, is the increase in thermal efficiency. This means that it will be easier to maintain the temperature inside your home. This is especially beneficial when considering the costs and efficiency of maintaining the temperature inside a building. With double glazing, heat loss can be reduced by half in optimal conditions. 

Double glazed windows are an ideal energy efficient choice with the added benefit of minimising noise. The sealed air gap between the two panes acts as an added layer of insulation. This added thermal resistance reduces the amount of heat escaping in winter and keeps your home at a more comfortable temperature. Double glazing has the reverse effect in summer, preventing unwanted heat from coming into the home. This extra insulation lessens your reliance on artificial heaters and air conditioners and can ultimately reduce your energy costs.

When you are close to a window, your comfort is also affected by the temperature of the glass. With double glazing it’s harder for the unwanted outside temperature to transfer through, leaving the inside pane close to room temperature. Double glazing also reduces condensation which can result in the unhealthy formation of mould.

Sealed double glazing is effective at reducing medium to high frequency noise such as the human voice. A difference in glass thickness between the inner and outer panes will improve sound reduction even further.

Double glazed windows are considered a safer option when compared to standard single pane windows. Two sheets of glass are a lot harder to break than one and for even greater security you can specify toughened or laminated glass. Thank you to the good people at Viridian Glass for assisting with the info.
