We are trying to get our windows sorted for our build. Energy report recommends double glazing to most of our windows. My question is will this significantly reduce outside noise coming in, or is there something else we can do/ add to assist with this? Mainly concerned just with noise coming in through bedroom windows.
Double glazing will have a major effect on noise, if you have a choice, choose thicker glass. But the walls and ceiling also need improved insulation for noise, like thicker Gyprok. Our window achieves Rw 34.5, meaning it stops 34.5 dB, check what others claim. Window sealing during installation is also very important.
