laminated glass question
« on: March 06, 2013, 08:38:44 PM »

Hi, I have vinyl dual pane windows that where new when we purchased our house in 2005. I don't know the manufacturer. I was under the impression that these windows are made of some type of acrylic panes. Is this correct? I have heard alot here about laminated glass as well. Is this a plastic material as well or real safety glass. I'm posing these questions because I want to add soundproofing windows to my house before addressing any sound issues with the walls. The magnetic window seals seem like a good place to start but I'd like to know if I need to take any further action to the windows I have already. Any suggestions where I could get think laminated acrylic in the SoCal area whould be appreciated. Also, Has anyone had any experience with clear mass loaded vinyl as a barrier between the primary dual paned window and the secondary magetic type soundproof window? Thank you, Jeff

The reduction of sound through windows is based on 2 principles. 1) mass of the glass or acrylic, usually we recommend no thinner than 1/4" and max of 3/8" on both sides of the system.
2) dead air space which is the dominant factor. The greater the air gap the better the reduction. For residential its usually 2" or more.. If I do a recording studio the gap could be up to 8" to 18" ..

Not sure about your windows, but you can acquire acrylic from either National city plastics in San Diego or MGM plastics here in San Marcos Ca.
You do not want to put the clear vinyl in between the system, leave it a true dead air space.
