Replacing single glazing pane windows to double glazing is a cheaper way to insulate your home, especially if you don’t like having PVCu windows and doors.
Plastic frames windows and doors,even thought they are virtually maintenance free, are considered to be in bad taste, and many people would rather have wooden framed windows and doors. Replacing the windows and doors with new – double glazed units, can be very expensive, around £2000 per (normal sized) window. If you have sash windows, the cost is even higher.
Single glazing can be replaced with double glazing if the frame and the structure of the windows and doors allows for a thicker glazing unit to be fitted. Sometimes the doors can’t accommodate the double glazing thickness for security reasons, and if the window has a large pane – the structure/frame needs to be reinforced in order to support the weight of the new double glazed unit, which is double of the original glazing.
In most cases, the glazing putty that older windows have around the window panes needs to be replaced, and the best way to remove hard putty is by heating it up using a blowtorch or a heat gun. Removing the paint and beading in this way will damage the paint work, but in most cases, the windows and doors needs to be repainted in the first place.
Double glazing or triple glazing units/panes are made from glass window panes separated by air or gas filled space (sealed unit) to insulate the building from losing heat. It also soundproofs the windows and doors.
The efficiency of the double glazing is measured in U – value and the most popular sizes are the 12mm, 16mm or 20mm air or gas gap , with 4 mm glazing x 2.
