Soundproof Windows Reviews | #1

Here are some tips to help homeowners out there make a decision about soundproofing windows.

1. Ask about the thickness of the glass and how it compares to their normal windows (glass thickness makes some difference but not much, however, still ask).

2. Ask about the airspace between the panes (this is the biggest factors out there and the more the better – this is the main “noise killer – 2″ to 3” is ideal, again the more the better).

3. Ask whether the sashes are solid and what type of insulation they have inside — hollow vinyl frames are bad from a noise POV.

4. Ask what the STC rating is (sound transmission class) – you want an STC from 45 to 54. A normal window ranges from 30 to 40.

5. Good window glazes and seals on the windows will make a huge difference.

6. If you are getting movable window styles, get casements as they usually rate higher than double hungs, single hungs and sliders because when you close them, the seals compress and block out noise.

Quietline Soundproof Windows Reviews

I live on a busy road and two months ago installed the Milgard QuietLines (45 STC rating). They were expensive (I think I paid about $800 per window (not including installation), which I believe is actually a very good price), and worth every penny. My condo is now soooo much quieter, the main culprit now is my walls which I’m guessing has an STC rating of 40. I can still hear certain vehicles drive by, but now only big trucks or motorcycles and they are faint enough that it doesn’t bother me. The QuietLines has two windows in one, almost like a double hung inside a double hung. It explains the big price tag, I’m sure there are other solutions but I wanted one that would fix it for good. I’m glad I did.

Surface Mounts To Combat Busy Road

We have a hundred year old spanish colonial home that is next to a road with loud traffic from trucks and other large vehicles. We bought the windows from Soundproof windows Inc. and they were very expensive. We went with single hungs with laminated glass and the install went well. They work really well and have really cut down on the outside noise – we can still hear traffic but it feels like the road is quite far away as opposed to right next to us. I was hesitant about the whole project, especially after reading about the disappointing experiences of people putting in lots of money and really having the same issues. We went with the surface mount that put about 6 inches of space between the panes. This was the key to the noise reduction according to the installers.

One Homeowner’s Experience

I recently put in soundproof frames in and I thought I would share my experience. Overall, it was a pain. They said I could do it myself but it’s a two man job for sure. The screws that came with the inserts weren’t strong enough to get into the frame channel and I had two snap. You need a power drill with adjustable torque speed to get the job done. I would recommend doubling the insulating foam along the window frame. Most walls aren’t prefectly straight and if you don’t, you will end up with small gaps which then need to be caulked. Placing the window panes into the frame is difficult by yourself so here is where the second helper comes in handy. Once installed, my double hungs were tough to slide down – I’d recommend getting a Teflon spray to handle this. Once the install was complete, I was very pleased with the noise reduction. The issue now seems to be the walls, but it’s now at least tolerable. I thought I would have a problem with the sill/surface mount frame but it has a relatively low profile. There are some downsides to the project; they were expensive and they are still a pain to open and close. All in all though I’m glad I did it.
