Hi, everyone! I´m new to this forum and very glad i found it, this soundproofing subject can be so confusing!
I really need some help, can someone please enlighten me??
So this is my problem: I live in a new building with pretty thin walls, I guess. My downstairs neighboor is driving me nuts with his very loud TV every other day untill very late at night (not to mention my upstairs neighboor but that deserves a totally independent topic...
). Sometimes I turn on my airconditioner and it´s enough to cover the noise, sometimes it doens´t help. Cars and trucks passing right under my window very early in the morning also bother me so I´ve decided to address both problems and thought about soundproofing my bedroom window and floor for a start.
Well, I had two different companies estimate the costs of a soundproof window and was offered two different configurations:
1) window #1 is a 3mm glass (something a little bit thinner than a 1/8" glass) laminated with PVB to another 3 mm glass + 9 mm
of dehidrated air (something a bit thicker than 1/3" of air space) + a simple non-laminated 4 mm glass (1/6" thick);
2) window #2 is a 3mm glass (something a little bit thinner than a 1/8" glass) laminated with PVB to another 3 mm glass + 6 mm
of dehidrated air (something a bit thinner than 1/4" of air space) + a 4 mm glass (1/6" thick) laminated again with PVB to another 4 mm glass
Both windows are made of aluminum and stuffed with some sort of soundproofing material (fiberglass, I think...).
Well, I´ve read everywhere that the thicker the air chamber the better the isolation but I´ve also read that quadruple glass windows isolate sound better than triple glass ones... So now I really don´t know which one to choose! I know quadruple glass windows may be an overkill but if they really isolates sounds better than the triple ones due to the extra layer of PVB and glass even though the dehydrated air chamber is thinner I´d definitely choose the quadruple one.So what do you say, what blocks sound best: a bigger air chamber or an extra layer of PVB and glass??
Thank you so much for your attention!!
