Whoever fitted the double glazed windows in my property (a few years prior to us purchasing it) didn't do a very good job on some of those windows that open and shut, therefore *not* affording an air/noise-tight fit. I've tried putting some of that draught excluder strip on the insides so it's squeezed when the windows are shut (the self adhesive strip) which has helped a bit but not as much as I had hoped.
Is there anything better/more effective that I could use to put around the opening windows so that when they are closed the seal makes a more effective air and noise-tight fit?
The windows don't appear to be adjustable so there's nothing that I can do in that respect.
Thanks
