Double glazed windows to reduce road noise?

Double glazed windows to reduce road noise?

The road noise from inside our house isn't too bad, but you really notice it on weekend mornings when there is a chance of a sleep in!

 

Our master bedroom is at the front of the house and it doesn't take much of an increase in traffic to wake you on weekend mornings.

 

Does anybody have any recommendations on double glazed windows being effective?  Did it make a difference to external noise and perhaps temperature control, too?

You will notice a difference in regards to noise. Whether its enough difference to justify the expense is the tricky part. You might want to consider other options first, like timber shutters? And again, you should get some benefit in terms of better insulation keeping your bedroom cozy, but if heat is escaping elsewhere then you might not notice any difference.

Re: Double glazed windows to reduce road noise?

Double glazing should be very effective, but custom make ones are expensive. There are double glazing products on the market, but be aware that more commonly advertised ones are generally for temperature control, not sound suppression/attenuation.

The difference between the two, is that temperature insulating window panes are set closer together, to reduce convectional circulation, which reduces the insalting properties. Sound insulation windows have the panes set further apart, so that the entrapped air between them, acts as an air cushion which reduces the air vibration transmission to the inside pane.

Depending on what type of window you have, you may be able to have glass sheets cut to size & fitted to your existing windows. To attain better noise suppression, use thicker glass for the new panes.

Polycarbonate sheeting is an alternative, but I'm not sure if there'd be any cost saving.

We have roller shutters to all our windows, but I wouldn't suggest them to reduce noise ingress, ours are for temperature control & security.
