If you combine 1" SSP Mat with 1 lb/sq ft Lead (1/64" thick) you are likely to get a rating of 33-35 STC.  This is based on noise reduction coefficient, NRC, of the SSP Closed-Cell Mat and the density of the Lead.

If you plan to put together a window plug using the SSP Mat and Lead then take into account the weight.

I was wondering if anyone can give me some suggestions on soundproofing our bedroom in our newly purchased home.  Our house backs to a road that seems to have a lot of truck traffic in the mornings and it's starting to drive me nuts!  The cars you can't hear because we're a decent distance away from the road, 300-400 feet with trees separating us, but the trucks you can still hear pretty clearly in our bedroom (speed limit on road is 50mph!!!).  I'm not as worried about cost as I'm worried about the effectiveness of a solution, I don't want to waste a lot small money and time on a partial solution (meaning spending multiple small amounts of money on trial and error).  My big concern is that the back of my house is vinyl and I'm wondering if protecting the windows is enough.  When I stand in the room it really does seem that most of the sound is coming from the windows.  If the windows are most likely the big problem what solution will give me the best results (I know I can’t eliminate the sound entirely)?  Would it be to replace my windows with Milgard windows or trying those add on windows from  I’ve browsed around the forum and haven’t found a good solid comparison between whether adding a second window is more effective then replacing your current windows with soundproof ones.  Please let me know, and THANK YOU very much in advance for any advice you may have.

PS If you happen to have any other advice about soundproofing my room, I am all ears!!!!

Hi Scott,

I have similar problems with you. My newly built house is by a very busy street (only ~45 ft away). We installed several soundproof windows from It does help to reduce the noise some but NOT MUCH! If I were you, I would try first to replace the existing windows with Milgard. Their prices are similar (For STC 40, about $500). of course, we need extra money for installing the Milgard ( i am not sure how much it will cost, you know?).  If it's still a problem, then try the soundproof windows. That should solve your problem entirely.

I am now in a delima because the installed soundproofwindows are still not good and I don't know if I should replace the existing windows with the Milgard.

Please let me know if you have any good news or suggestions. Good luck and have a good day!

I got a quote from a Milgard rep for two Sound Control 7220 Series windows.  The quote was $585 each, for a window 2.5'x5' (windows were 45 STC configured, and had the low-e and grid option) I then had someone come out and they gave me a quote of $150 each for replacement cost.  So I'm looking at about $1500 to replace two windows.  

I really want to give it a try but I'm afraid that it won't make much difference.  Especially since you didn't have much luck with those soundproofwindows add on windows.  I'm worried that the windows are just the primary contributor to the sound problem, and there will only be a slight perceivable reduction in sound.  $1500 is a lot to dump out to get just a small difference in sound reduction and I don’t know if I’m ready to go to great lengths, like installing second pieces of drywall; insulating my attic furnace/venting system, to stop the noise.  I really wish someone could give me some real world results before I give this a try.

I think almost everyone has this problem.   I can really hear traffic noise all in my house in the early mornings.
I have learned to accept the noise and not get upset by it.  I also have an air purifier in our bedroom which is on all night.  It drowns out all noise from outside and keeps the air clean.  Ceiling fans and other fans also muffle sounds.  Wear ear plugs too and use a lot of fabric in your bedroom, like very heavy curtains.  I think the main thing is to accept that life is not perfect and all things considered, there are many worse problems in life.

Have solved a lot of noise issues myself.  Here are some tips:

1) For soundproofing materials, see

2) To soundproof windows, it's important to have different thicknesses of glass separated by as large an air space as possible.  Two panes of different-thickness glass is good; three even better.  Using laminated glass in one of or more of the glass panels even better yet.

3) Most importantly, sound will infiltrate even the smallest opening of gap anywhere in the windows or walls.  Joints and seams must be 100% sealed, no ifs, ands or buts.

Good luck.

 :) I have a similar problem to the above posts with nearby road noise coming through 4 very, very large master bedroom windows (the smallest is 6 feet by 2.5 feet). I bought the house for the fabulous panoramic view (I sit way up on a hill) but now I must suffer the road noise from down below. I have been trying to reduce the noise as much as possible over the last three years. My wife calls it a part-time hobby for me. I now have triple pane glass windows (new and expensive), combined with a single plexy glass insert using the magnet seal window system and guess what ….I am still not satisfied. The noise is way, way better than when I started with 10 year old double hung 2 pane glass windows, but it is still not OK at several frequencies. Deep bass frequencies are still not low enough to suit me. Routine car and road noise is very low, but the lower bass noises are tough to deal with. I even tried laminated glass in the old windows…and that did help...but not enough. Next up….rollershades for noise reduction at night and hopefully an end to Harley riders waking me up with a quick acceleration down the street.  >:(

I live in Miami Beach and my aprtment is very noisey due to traffic noise, car alarms, and whizzing mopeds.  Soundproof Wndows, Inc installation will be complete in February 2005 so I will write back to let you know results.

I picked Soundproof Windows, Inc.  for three reasons,
1) Everything I read says a second pair of inside windows reduces noises much better because the airplace between the 2 windows (about 4 inches, the width of the window sill) is the key ingredient that stops noise.  This makes sense to me.
2) referred me to two Miami Beach customers who made these comments" I love my windows, noise reduction is signifigant, about 80%" , and , "it was the best investment I ever made".
3) I spoke to the installer named Jack , and he seems competent.  tel:877-438-7843

Three custom made windows for my bedroom for $1700, delivery 8 weeks.  Another customer of theirs said price was $2100 for 3 windows.  It depends on the size.

I had 3 installed in my bedroom in Miami Beach.  I feel the noise decreased by 75%.  I now sleep soundly, when before I woke up 5 times a night to traffic noise.

The only noise I still hear is nearby car alarms.

Jack, the authorized window installer in Miami area, did a super job.   He was quick (2 1/2 hours to intall 3 windows), excellent chalking,  looks perfect.  One week later I asked Jack to adjust window so it slides easier and he was very happy to returned in 4 days and adjusted window to my complete satisfaction.

Hi I am so thankful I found this website. I live about 20 feet from a very busy street (50mph) in california and I have dual pane window but it is still driving me nuts.

I want to install soundproof windows but worry that it would be as effective.

I have contacted Milgard, and Acoustical inc.

About Milgard, Can anyone please kindly let me know what is their series that would work. I know their quiet series is good but don't know how much it cost and if it is effective.

Acoustical inc, seems to be good beacuse I don't have to replace my current wondows but I called the number on the website and they don't manufacture that kind of window anymore. Does anyone know of similar ones? or if I could buy the acoustical windows from somewhere else?

I have a contractor and he showed bem this window made by International window and apparently it worked for people living next to freeway. Only thing is it has 4 sliding panel and it is rather costly to replace. Anyone who is interested might want to check out

I really Thank anyone who can help me or give me some feedback.

THANKS again sincerely.

We recently purchased a house that we love - unfortunately it's close to a freeway.  I didn't think the traffic noise would bother me too much, but it is.  We moved from a very peaceful community with no traffic or neighbor noise and the adjustment has been painful.  

I've been in touch with a local soundproof window company and Soundproof Windows.  I am leaning towards Soundproof Windows (out of California) because they are interior windows that open and close like our current double-pane windows.  

I would appreciate hearing from anyone who has installed these windows to hear your experience with them.  The quote I got was $2,000.00 ++ for 3 windows for our upstairs (they are each about 72" long).  I don't want to spend that kind of money only to find out that the noise reduction is minimal.

Thanks for any words of wisdom.

Hey folks, here's an inexpensive treatment I did and it helps somewhat.   I bought sheets of 1/8 inch plexiglass from Home Depot ($135 for 5 60x30 sheets)
cut them to size to fit over the wood frame of my existing double hung single pane windows.  One goes on front of inside sash, the other on outside of outside (top)sash.  Screwed them in place, rand sealant around the edges.  The hardest part of the job was taking off the storm windows so I could get at the outside of the outside sash.  It does deaden the noise a bit.  As much as sounproof windows sold on internet?  I don't know, but the concept is the same and the windows still operate and the cost is about 1/15th.

Moderator:   Very Good!  The disadvantage is the fact they are cemented into place.  Making them removable is inexpensive and easy:  see the "Poor Mans Interior Windows at:

Does anyone have experience or feedback with QuietHome Windows of Quiet Solutions, Inc of Sunnyvale, CA?  They are a relatively new sound-window company and offer replacement windows similiar to Milgard but can manufacture them for a retrofit style to fit over existing frames, therefore no need to rip out the old frames.  We open and close our windows frequently for ventilation so would be awkward for us.  Any feedback much appreciated.  Thanks!

I've had the same problem.  We bought a condo next to a major street, (20 feet from the street).  Our bedroom and living room face the street.  Our challenge is that the previous owner enclosed the patio, so there is a HUGE window opening.  I looked into Milgard's double pane window (1/4 over 1/8) and it is supposed to have STC of 34.  I also looked at Soundproof windows and it costs the same as Milgard's double pane.  Since our old windows are ugly anyways, I spent about 3000 replacing our existing ones with Milgards.  The noise is definitely muffled a LOT, especially in the living room, but the bedroom is still pretty loud, probably because we have a retrofit window.  

So now after spending 3000 and still not satisfied.  I'm thinking about spending 700 to just add soundproof type of windows in my bedroom.  My milgard dealer told me that they have this window named Quiet Windows, that does exactly what Soundproof windows does, but this company only sells to dealers (in Long beach).  Guess what I found out, Soundproof window used to be one of their dealers!  And the guy told me they had a fallen out.  So anyways, this company actually charges less than soundproof windows.  For the same window, soundproof charges 688 not including installation, and my dealer will install the window for 700.  So I'll rather spend 700 dollars to have someone else install my window.  

If you are interested, call and see if he has dealers in  your area.  (562) 435 2220

Live close to a busy street, the previous owners installed smaller windows in the bedrooms so the noise has been reduced quite a bit. But there is a large double pane picture window in the living room.  The window doesn't open so I'm thinking of putting a 3/8 or 1/2 inch piece of acrylic on the inside of the window with about a 2 1/2 inch airspace. Then either securing it with clips and magnetic tap or caulking.  Does anyone have any experience with this sort of handyman solution?
Thanks in advance.

I am happy I found this site. It proves to my wife that I am not the only one with these issues. Here's what we have done.

We recently purchased a house that we love, but it overlooks the freeway. I thought the freeway noise wouldn't bother me but it really does. We live in Oakland, CA and have been working with Bay Area Noise Control who specialize in residential noise reduction. They have relaced 8 windows and a sliding glass door with Millgard QuietLine windows. For the sliding glass door they also built and additional frame and intalled a second 1/4" sliding door in front of it (creating a dual sliding door).

The reduction in noise from these QuietLine windows has been signficant. They rate the QuietLine at 42-47 STC and the double sliding door at around 50 STC, so there has been a marked improvement over the cheap 1980s aluminum dual panes we had before. It hasn't been cheap (about $20,000 so far) but has been worth it.

Worth noting that sound will leak in from anywhere, so one thing you need to be careful of is how the gaps around the windows are filled. They stuffed mass loaded vinyl into the gaps then sealed them with acoustical caulk. A normal installer may just spray foam into the gaps, which will just leak in noise and negate any STC reduction you got from the windows.

That said, I am still bothered by low-frequency noise, particularly motorcyle or truck downshfiting or rev-ing (the freeway is on an incline so we get a lot of rev-ing as vehicles head uphill). I am considering building inserts for the windows out of mass loaded vinyl sheeting and QuietRock drywall. Also considering re-drywalling the room with QuietRock. Anyone had experience with either of these products?

Thanks in advance.

I am in the process of replacing some windows in my house for soundproofing.

I have single panes with aluminum frames and live very close to the railroad, a quite busy street that runs right next to one of the busiest highways in Amercia (Hwy 5 in California).

Since I would like to achive sound-proofing first I am thinking to start by adding first an additonal set of windows like, and then if my budget permits, I will replace the existing single pane windows.

Is this a good strategy?

I guess I will try to get a quote from,, and the person from Long Beach. I will keep you posted about the price difference!

I have a 72x58 window in my bedroom, with a loud street directly behind it. I have researched all the websites regarding soundproofing. I think I am pretty set on adding a second window, 2 inches from the existing window, to block the noise. Instead of paying $1000+ for one of these companies to come out and install a second window, why don't i just go to home depot and buy a second window for $200 and install it myself. I guess my question has to do with why use's or whoever's product verses just going to get a second window from a hardware store.

Thanks SuzanneR, I was looking for someone to give an accurate depiction of how the performed. If you go to their web site, they have these testimonals http://Http:// and as they sound ok, I don't see WOW THE ARE AWESOME AND I AM READY TO BUY STOCK IN THE COMPANY.

I found this message board. I have just bought a condo in MA on a busy street.  I am located about 50 ft from the street, and hear lots of noise mainly buses and loud engines.  I knew that when I purchased the condo that I would have to get use to the noise. However, I seems that I am now fixed ON the noise problem and have had new levels of stress and anxiety.  I have been researching what do do for nearly one week. I am on the verge to trying the because I have double pain harvey windows already and if I install the windows over the pre-exsisting windows it will give me almost 4.5 inches of space glass (old) to glass (new).  From my research on their site, they say this is optimium.  However, a piece of me feels as if they are a snake oil medicine show, trying to pray on needy victims whom are so desperate they are will to try anything.  

Does anyone have a very positive thing to say about I mean, is anyone completely satisfied? Is the difference remarkable like there website says?

If this does not work I am going to sell my place.

Although I can not attest to the performance of "Sound Proof Windows", I just installed a 2nd window behind my existing window that I bought from home depot. Once it was completely sealed the noise from the street behind me was reduced greatly. I definately recomend adding a second window...thats the way to go!

mjm, could you give more details as to how you did this?  Is the new window on the inside or the outside of the existing one?  What kind of window is it, ie double hung?

I'm not handy, and would appreciate any advice!

Post by: mjm9813 on June 12, 2006, 07:28:43 PM
Pamela, the existing exterior window is a double hung 72 X 58 single panel. I purchased 1 horizonal slider 72 x 58 dual panel from Home depot and placed it on the interior side behind the existing window. The new window was about 2 1/2 inches deep so it left about a 1 inch gap between the new and existing window. I added a few shims to line it up and get it square, then put about 5 screws in it. Once it was secured, I used expandable foam spray  (I do not recall the brand, but can be found on the paint isle at homedepot) to air tight seal the gap around the new window. Once it expanded and cured, I cleaned it up and put the blinds and curtains back up. Shoot me an e-mail at and I have a small picture of the new window. The whole project took about an hour and cost $250 for the window. Let me know if you have any other questions.

Hello Scott,

Replacement windows from Milgard is the best place to start.  On the "sound control through windows" link this option is listed as #1 because it is the most effective.  See

The reply by Alan (5/11/04) below is simple and complete.

If your walls are also a problem, the easiest way to stop the mixed frequency sound/noise from the traffic is to use a layer of Green Glue sandwiched between a second layer of dry wall (1/2" is OK for second dry wall layer).  This will give you at least 56-61 STC, depending on the starting STC of the existing exterior wall.  The best part is it will lower the resonant frequency of the wall and block even low, low frequency noise/sound from coming into your room.  For Green Glue info see

I've enjoyed reading the messages on this site.  I don't have a major noise problem, but I'm considering replacing my VERY cheap windows with something better and I am looking for recommendations.  Has anyone tried Loewen's Tranquility Series windows?  Their casement windows test our at STC40.

Post by: johnbergstromslc on October 05, 2006, 09:19:14 PM
Except for non-operable, permanently sealed units, casement windows tend to be the best at deadening sound.  They close up the tightest.

STC 40 is excellent.  If they're reasonable in price, I say go for it.

Ok, after reading all this posts I am still confused by the idea if the really work or not. I am planning to purchase them but I am very concern about doing so. It's a good chunk of money! :-/

I had the gentleman from Bay Area Noise Control here at my house. He was very knowledgeable and nice guy but his cost to install and the windows is above $9k for 7 windows and one door. Is very high in my opinion since ordering direct from is $3k without installation. I can't justify paying almost $6k more just for the sake of installation.

I am very worried so I would love to have a sincere statement from you guys that have these windows at your home so I can make an educate decision about it.
I read here that some you like it and others don't saying that it solved only 25% of the noise problem. If I am spending this money I would expect at least 75% or more noise reduction.

As few of you stated I also live close (60 feet) to a busy street with lots of traffic in the morning with cars and trucks.

Also I want to thank this forum. Very nice information. Cheers for the good work. :)
All the best.

Be careful, just about none of the BS works.  I have a busy street in front of my house too and none of these soundproofing windows or anything works.  The noise is too sporadic for them to be effective.  If it was constant highway drone, they'd work.   Other than completely sealing off the windows, you're not going to be happy.  I'm selling my house to live in a quieter area.
