Hello there.
Making this posting in the hope that it might help out somebody else.
We moved into our house about a year ago and we've had an issue with the windows in my son's bedroom. Our house in on quite a busy road albeit set back somewhat. Yet around the edge of the windows internally, especially on one side, there has been quite bad traffic noise coming in. A problem early in the morning as it's been waking my boy up.
Have checked the seals of the windows, the sealant between the frames and the wall externally and I even removed a little sealant to check that any void had been suitably filled with insulation. All seemed well.
Anyway, this evening I was looking over the problem again and have finally cracked it (the cause, not the window). It seems that the window frame is slightly bowed inwards on one side - ever so slightly, but nevertheless, enough to make the contact between the opening/closing part of the window and the frame less tight than it should be.
Where the apex of this bow is, located inside the frame and on the moving window, are two opposing plastic wedges that interlock when the unit is closed. As the frame is bowed, I guess these wedges aren't pressing together as efficiently as they should. With this in mind, I cut a small rectangle of plastic (old CD case) and sandwiched it between the two wedges as the window closed. The level of noise has dropped noticeably. There is still traffic noise, but it seems a lot more suppressed and more evenly distributed across the whole window.
I think I'm going to look at replacing the glass units with acoustic suppressing ones. I know that secondary glazing is the ultimate, but that feels at this stage like cracking a nut with a sledgehammer.
Anyway, thanks for reading and hope somebody might find this useful in the future.
Best,
Dan
