Milgard Quiet Line vs. Wood Laminated Dual Pane
« on: May 11, 2012, 01:16:35 AM »

My house is right next to El Camino Real (6 lanes busy street. most cars speed are 35-45). Could someone please recommend the brand/line of sound proof windows? Thank you very much for your help!

1. Milgard Quiet Line-
a. Is it effective for non-highway traffic noise (speed 35-45)?
b. Is there other brand/line that works better than Milgard Quiet Line?
c. I went to Home Depot, and they told me about Jeld Wen Soundmaster windows. Is that better than Quiet Line?

2. Wood Laminated Dual Pane-
a. Two contractors came to my house both recommend wood laminated tempered glass dual pane. They said Milgard quiet line doesn't look good. They also said since I have wood window currently, I will be disappointed if change to Vinyl. But the wood windows currently (Dual pane from 10 years ago. Not laminated. Not sure which brand. Probably Pella windows) are noisy.
Renewal by Anderson guy told me their wood laminated tempered glass dual pane (STC33. OITC 29) will work better than Milgard Quiet Line, which are Vinyl. Is that true?
Another contractor recommends Jeld Wen premium wood windows (dual pane laminated glass). Is it more sound proof than Quiet Line or other brands that you recommend?

Thank you :)

Thanks for sending me the stc oitc MagnaSeal.  It helps me a lot! :)
Today two window guys are recommending keeping the wood frame and just replace the glass.
First guy recommends outer layer 3/16 and inner layer 1/4 laminate (stc 37-38), 9/16 spacer.
Second guy recommends offset glass 3/16 and 1/8, no laminate. He said stc is around 34 with offset glass. If adding laminate, stc can increase to 36, but price is 3x.
Is just replacing glass effective for reducing sound? Because the other window guys are saying I need a new construction to get complete seal, otherwise sound will come through from space between glass and wood frame?
Currently I have 11 year old Loewen Steinback wood regular dual pane, 1/8 and 1/8, less than 1 inch spacer. Current windows are noisy. House is single level.
 I am not familiar with windows, so not sure if replacing glass is effective enough to block traffic noise?

Im not a window expert either, but the most important thing to accomplish is an air tight seal...... this is a must, so if you have leakage around the casing then you should have it sealed up...
