(Please note the below specs do not apply to the clear vinyl panel which would have the same rating as the 1 pound MLV)

About the Material:



The Barrier Septum Composite (BSC) is a non-reinforced loaded vinyl noise barrier, sandwiched between two layers of fiberglass. Ideally suited as an acoustical liner, the inner layer of the quilted fiberglass decouples the barrier from the surface to improve its noise blocking ability while the outer layer adds sound absorption to the treated environment. Exterior material is a standard industrial vinyl facing, available in gray, tan, white or black.

  • STC: 29 (see product data)
  • NRC: .75 (see product data)
  • Fire Rating: safe and low smoke emissions as per Class A flammability rating (per ASTM E-84 ).
    • Flame Spread: 22.78
    • Smoke Density: 30.56
  • Temperature Range: -20F to +180F
  • Weight: 1.43 Lb / sq ft
  • Resists most chemicals
  • Durable and flexible, conforms to any shape
  • For interior applications
  • Easy installation and removal for cleaning

Comments about Soundproof Window Panel:
I just installed the panels. Which were easier than I thought because of the Velcro — thanks for that. They're heavy! Even the clear one was heavy. That was a great idea to use a Clear on one window btw; the room would have been completely void of sun otherwise. I've done some preliminary testing and the reduction in noise is, well, incredible. Much greater than I initially expected. Planes that fly directly overhead, that were clearly loud, I can't really hear them anymore. Seems that double-pane windows aren't actually that good at blocking sound at all.
Bottom Line Yes, I would recommend this to a friend

These are very well made and I put them up yesterday without a problem. Working today on computer not hearing outside noise is great. I see weatherproofing and keeping the Las Vegas sand out extra bonuses. Happy Holidays and Happy New Year!

Customers Questions and Answers

1) Nick : Have a window that is 74" in width about 50" in Height. What do you recommend? Cordially, Nick

Trademark Soundproofing Reply: Hi Nick, We would recommend a Window Panel 78" x 54". If you would like a price for that please email our sales dept.

2) John: Does the velcro strip around the window come in white as well as black?

Trademark Soundproofing Reply: Yes. That can be requested in the customer notes box when checking out or by giving us a call. Thanks.

3) jeff: How should I measure for a sill that juts out from the window at the base?

Trademark Soundproofing Reply: Hi Jeff, Add a few inches to the length to allow you to go over the ledge and attach it below the ledge.

4) Diane L: I will be calling tomorrow to place an order. I have two questions- 1. Is the window panel as easy to apply as it looks? 2. I live in Canada and my order is under 1000 dollars. What can I do to convince you to mail my window cover to Montreal, Canada! Of course I'm willing to pay Fedex/UPS charges.

Trademark Soundproofing Reply: Hi Diane. Yes it is as easy as it looks, however it is heavy at 1.2 pounds per sf, so it will depend on the size you are ordering. Please send an email to with your address and order details and we will try to help you. Thank You

5) Lisa T: Hello, I'm interested in this product to block out dog barking, lawn mower noise, etc...I am trying to decide between your product and this one: How do you compare and what is your return policy if your product does not work? Thanks, Lisa

Trademark Soundproofing Reply:

Hi Lisa, Our window curtain is made from the highest quality commercial grade material and works great we have sold it as window and door blocking and have many repeat customers. Every order is custom cut to size therefore they are not returnable. We cannot comment on the other curtain you mention, you can read their customer reviews online here.

Keep in mind that the window is a weak link in sound control, however you can have noise coming through your walls and ceiling too.

6) Mike Swift: What is the sound attenuation in db?

Trademark Soundproofing Reply: Hi Mike around 27.

7) Lorraine M: Hi - Does this do a good job blocking noise from fireworks?

Trademark Soundproofing Reply: Hi Lorraine, yes it should help cut down a lot on that type of sound coming through your window.

8) Vern L: Are the soundproof window panels equally effective at reducing the sound traveling out from within a room?

Trademark Soundproofing Reply: Hi Vern, Effective equally going both ways. Thank you.

9) Robert K: I live on a bluff about 40 feet above and 75 feet away from a busy street. The traffic noise especially the high frequency whining from motorcycles and skooters, and the low frequency noise from big trucks rumbling up and down the hill keeps me up at night. I already have quality double pane, laminated windows, so what percentage sound reduction can I expect? 10%? 25%? 50%? Please give me a honest answer. If you prefer let me know how many decibels of reduction I can expect. I get about 65 db of noise at the worst and 30db when no cars are going by. I do not want to buy another product like an acoustic curtain that makes a 0-10% difference. Thank you! Robert Krause

Trademark Soundproofing Reply:

Hi Robert. We are getting around 15db which is over 50% provided that the sound is coming through your windows and not through walls/floors/ceilings. You can see our videos here:

10) Judith : Would your product stop a barking dog noise? Shrill bark, Chiwawa? (sp)

Trademark Soundproofing Reply:

Hi Judith, It would definitely cut the sound down tremendously. It is hard to give an exact prediction as the sound can still carry through walls etc. You can see this video on a real life sound test

11) Youngmin K: Hello, I am trying to figure out the best, least intrusive way of sound proofing the walls of a bathroom. The bathroom in my apartment shares a wall with my bedroom (there is a built-in closet between that wall and the bedroom space). The main problem is that sound of water running through the pipes (plus every bump coming from the bathroom, including toilet flush, etc.) echos loud and clear through the wall into my bedroom. It even passes through the closet even though I have clothes and other materials (some boxes) stored into that closet. My neighbors in the next door and the downstairs apparently run into very different schedules, so I am constantly woken up by hearing water rushing noise as late as 2am, and as early as 5am. I have not been able to have a decent night sleep because of this. Since this is a rental apartment, I figured that installing sound deadening drywall/sheetrock or using something like Green Glue would not be possible. While doing some research for fixing this problem, I discovered soundproof window panel in this website, and some plans come up with my mind: I am thinking what if I put this panel against the wall within the closet (where bathroom noise comes out and transmits to the bedroom). Do you think using soundproof panel in this way helps absorbing the noise coming out of the wall? Or, are there any recommendations using other products (in this website) to soundproof that wall? Thanks in advance for your advise. I look forward to hearing from you soon. Regards, Youngmin

Trademark Soundproofing Reply:

Hi Youngmin, The correct way would be using sound damping as you noted. Being that is not possible you can use a panel however keep in mind that some of the sound could be coming through your ceiling as well. If you go with a panel also look at our soundproof curtains which are the same material s the window panels in larger sizes.

12) Debra: About the clear vinyl covering- do you have a a video that I could see this product on the window?and a demonstration of noise block. is it possible to secure this under my blinds ? I wand a product that will look nice and will blpck road traffic noise, -

Trademark Soundproofing Reply:

Hi Debra, You can see that on our window panel video at the 1:20 mark here and another video here with it on the window and actual noise blocking here   

Thank you,

13) Zhaoxu: About the clear vinyl covering- do you ship them to UK? If yes, how long would it take, and is there an option to choose a faster delivery with extra costs? Thank you very much.

Trademark Soundproofing Reply:

Hi Zhaoxu, Please see our shipping page for details on international shipping.

14) WOLETTE : is this price for real? 1 window panel for $299.00 or is it a few panels?

Trademark Soundproofing Reply: Hi Wolette, Price varies per size of panels. Once you choose your size from the drop down menu you will see the price. price is per panel. This is a high quality custom made product and the price reflects that.

15) Olga M: I did not find information on how much noise reduction are your Window sound barrier provide. Please let me know measured in % of noise reduction or any other way. I am interested to buy clear panel.

Trademark Soundproofing Reply:

Hi Olga. Please see these videos.

16) Daniel: How would this product work with windowsills? Wouldn't it prevent the padding from completely sealing off the entire window?

Trademark Soundproofing Reply: Hi Daniel. You can actually attach the panel to the window sill itself.

17) Chris L: Your website does not show a photo of what your soundproof window panels look like from the OUTSIDE of the building. Are they plain white, beige or black? Our HOA CC&R's dictate that all window coverings must be neutral in color when viewed from the outside of the building. Please advise. Thank you. Chris LeMond

Trademark Soundproofing Reply: Color is the same on both sides.

18) Veronica K: Hi, I am interested in the product though I have wide window sills and frames. How bendable is the product? My window looks nothing like yours in the video. Am afraid the curtain won't lay flat and not work properly.

Trademark Soundproofing Reply: Hi Veronica, It is flexible and with 2 inches of Velcro on the edges you should have a tight seal even when installing it onto your sills.

19) Dan C: I'm interested in this product. But I don't want to spend $500 for a window not knowing for sure is this will do what I need it to do. Is there a money back gurantee with the product doesn't do what I need it to do? Please advise

Trademark Soundproofing Reply:

Hi Dan, These are custom manufactured per window size so they are non returnable. We have had great feedback from customers. This video may be a help for you

20) Chris t.: Hi, we can hear neighbors voice from our bedroom in our apartment (mainly through the shared wall). do you think if we hang this product (sound proof window panel) on wall , it could help dampen noise. we were thinking about 48 X 72 size.. that might cover about 1/2 to 3/4 of the offending wall .. or would the Sound Curtain- Heavy Duty be better? also, are these made of safe materials to inhale every night?

Trademark Soundproofing Reply: Hi Chris, You can use it that way. For proper sound control you would want to cover the entire wall. You may want to consider adding

21) Jeremy R: How does installation work if there is a window sill at the bottom of the window?

Trademark Soundproofing Reply: You can attache the bottom to the top of the sill. Or you can order a few inches longer and go over the sill to the wall below.

22) Stephanie: Hi - we are in Singapore - we want to order 2 panels... are you able to ship to us? Regards, Stephanie

Trademark Soundproofing Reply: Hi Stephanie. Yes that is possible. Please send details of the order and the ship to address to

23) Julie M: I have a window sill/shelf on all of my windows. How would the velcro seal on the bottom of these windows?

Trademark Soundproofing Reply: Hi Julie. You can go over the sill to the wall under the sill. Or you can seal to the top/flat part of the sill.

24) Ciaran: Dear TM, I am looking at your soundproof window panel. It says they provide STC 29, yet I have read that the average STC of a single pane window is 26-28. Is my data correct? If the product offers such a marginal difference to STC, how can it be reducing the sound entering my home. I look forward to your answer. Many thanks. Ciaran

Trademark Soundproofing Reply: Hi Ciaran. It is an additional 29 STC points. However it will not be a full 29 points when put over an existing closed window (the STC 29 is when it is free standing on its own) more like somewhere between 7-15 points as shown in the video.

25) Destiny: Do you ship intl? Im in the UK

Trademark Soundproofing Reply:

Hi. Please see our international shipping policy.

26) Metheavy: Hello, I might be interested by your soundproof window clear panel. I would like to use the velcro. However, my top, right, and lower windows frame are 1 inch wide, instead of 2 inches as required. Can I still install the clear panel on my windows frames? Or can I install the velcro directly on the windows? Thanks

Trademark Soundproofing Reply: I would not install it onto the window directly. Rather use the 1" of space and strengthen it with mechanical fasteners like staples, that should hold it in place.
