Combining Secondary and Double Glazing

reford89

Hi everyone,

We've just moved into a beautiful 1700s house. We love it, but it is very close to a road, and hence looking to do what we can to minimise the noise. There is currently single glazing, with secondary glazing throughout. In the lounge, which is the room closest to the road, this is really effective and we can generally sit and watch TV in the evenings without being distracted (you still get a bit of a low pitch rumble but we think we'll get used to it).


However, above the lounge are two bedrooms with the same setup (single plus secondary), but the windows seem to be much older and the single glazing windows have warped so that there are big gaps between the frames and the windows. You can hear much more of the road noise up there.


I'm planning to replace these windows with timber framed double glazing (it's in a conservation area) and keeping the secondary glazing, however, I have read online that there isn't much benefit to adding secondary glazing to double glazing.

My assumption was that we'll end up with less noise upstairs than downstairs but is that too simplistic?


Thanks!

I have it, and it's amazingly quiet.


The only thing I might worry about is the weight on presumably timber framing?

That sounds positive! None of the companies who have quoted have mentioned weight as an issue fortunately, and all have said it will make a big difference, but really good to hear from someone who has had experience so thank you!

You can get noise reducing double glazing - I guess it is expensive but might be worth it.

Just ask whoever is supplying the windows to use a 6.4mm acoustic laminate as part of the DGU make up, any DGU manufacturer can make them as long as weight isn't an issue.
