About Double Glazing
Traditional window glazing consists of a single sheet of glass within your window sash. Double glazing consists of two panels of glass which are separated by a layer of air or argon gas and then sealed.
The air creates the insulation break which greatly reduces both heat flow and thermal conductivity through the window.
Double glazing is often known as Insulated Glazing Units (IGUs). Double glazing thermal benefits makes it ideal for windows in rooms where there is the desire for more control of heat gain and loss through the glass.
Double glazing is best applied to the rooms most affected by thermal impact.
Consider why you are wanting double glazing: are there other glass types that will have the same result? Low E glass for example is often a cost-effective alternative.
- Excellent insulation performance reducing your energy costs
- Can minimise noise if the right glass combination is used
- Reduces condensation
- Different glass types such as Low-E and Laminated can be used to further increase energy efficiency and noise control
- More expensive – consideration should be given to the longer payback period on your energy bill.
