The double glazing in many homes is now becoming quite elderly, and with some early units with only a 6mm gap between the panes it may well be that many householders should be considering whether replacing their old units for more energy efficient ones may well be an investment.
It’s not just the fitting energy efficient windows saves more energy and therefore leads to smaller bills it also is about enjoying having warmer rooms and no more draughts. Even less of the heat that you put into the room will be dissipated through the glass and more stays in the room.
Older double glazing units will also begin to fail and become steamy, and at this stage the value to the home in energy saving is much reduced – not to say the overall aesthetics seriously compromised as the vision through the glass decreases.
It really will be worthwhile to get some double glazing quotes from different companies to find out the cost of replacement units. The wider the gap in the units (modern ones will be 12mm or 16mm) the more the unit will cost and the provision of different types of glass for example, self cleaning) will also affect the price. It will be possible to look at replacement as an investment over a period of time – and even look at replacement in the rooms you put them most heat in, or where the units are most clouded. Done over a period of time the cost will be manageable – and the savings will also have an overall impact in the long term.
