Hey - Just after some info please,
I am waiting to hear back from the builder about this but thought I would see if anyone on here knows what this is about.
We are near the airport here and have to meet these noise thingys and we were told that some of the windows need to be 9mm thick glass. Most of the windows were installed today and I couldn't work out which ones were thicker but in 3 of the bedrooms there are 2 frames and I don't understand what they are for. So any ideas would be great.
