As replacement and double glazed windows and doors are available in a wide range of styles and designs, the double glazing panes of glass can vary according to the cost and manufacturer. As the name implies double glazing is constructed with two panes of glass with an approximate 16mm gap between them.
The best type of double glazing panes are those which have an unobtrusive coating of metal oxide, referred to to as low emissivity, Low-E, on one of the inner panes, as these are most energy efficient. They allow sunlight and heat through but reduce the amount of heat which can escape back out.
High efficiency windows have gases such as argon, xenon or krypton between the gap of the two double glazing panes. The double glazing panes are kept apart with pane spacers which are set into the inside edges. The more efficient windows have pane spacers which contain no, or very little, metal. These are also referred to as ‘warm edge’ spacers. For the most energy efficient double glazing panes look for those with an energy efficiency rating of A-G, with A being the most energy efficient. Double glazing panes and units which have the Energy Saving Trust Recommended logo means that the double glazing is rated B or above.
