BENEFITS OF DOUBLE GLAZING
Double glazing is an insulated product and will save the use of energy such as gas and electricity in your home. By double glazing your whole home, you will get the benefit of lower energy bills, no draughts and a comfortable home. Putting solar panels on your roof will also cut down energy bills, however, it won’t provide the comfort that double glazing provides. You will still have draughts and uneven temperature in your home.
Standard double glazing with at least a 12mm gap is effective at reducing the transmission of medium to high frequencies (human voice). For low frequencies (traffic) using a different thickness of glass in each pane, or incorporating laminated glass, can help to cut noise.
The best outcome for noise reduction would be to have a very wide airgap between the panes of glass. The next best outcome is to use a laminated glass on the outside pane of the double glazing.
