Home and Office Soundproofing Solutions


Soundproof Existing Windows for a More Peaceful Space

You can simply and cost effectively soundproof any room in your home or office with our soundproof window inserts and soundproof sliding doors. Imagine blocking up to 75% of low-pitched noise (traffic, A/C compressors, etc.) and up to 95% of high-pitched noise (bus brakes, pool pumps, etc.).

We do all the work – we can install most soundproof window inserts in a day and quickly make your home, apartment or office a more quiet, productive place. Plus, you’ll save on energy since the windows also insulate against cold and heat.

Inserts Manufactured in Texas

Sun and Sound Windows has proudly served customers across Texas for over a decade, with service locations in the major metropolitan areas of Houston, Austin, and Dallas/Fort Worth. We manufacture all of our laminated glass inserts in the United States, so you can expect the industry-leading performance for which our products have become known. Our inserts are custom-made for your windows, and installed at your home or office by our knowledgable and friendly experts. Get in touch by phone or contact form for a free cost estimate today.


First of all, they are not replacement windows. They’re laminated glass window treatments that we install on the inside of your window opening, in between your existing windows and your blinds, shades, shutters, curtains or drapes. They’re ideal for residential and commercial windows since they don’t change the look of your home or office and they comply with homeowners’ associations regulations.

We can make custom sizes and shapes and usually install them in one day or less, without messy construction. Soundproof window inserts typically cost 50 percent less than soundproof replacement windows.


  • Insulate against unwanted noises from traffic, construction, outdoor equipment and more
  • Protect against energy loss, both cold and heat
  • Reduce the ultraviolet light that fades carpets and furniture
  • Minimize window condensation Decrease drafts and allergens


The air gap that is created between the soundproof window insert and the existing window produces an insulated sound trap, where sound waves are absorbed, reflected and cancelled. The result is a much lower volume of sound that makes it through the sound trap into the room. The air gap also reduces energy loss by 60% per window.

The seal of our soundproof window inserts is important because sound can act like water, seeping through openings. Our infiltration rate is less than .01 cfm/lineal foot, which far exceeds the International Energy Conservation Code (IECC). Please note that “soundproof” drapes or curtains typically do not have a seal around them, allowing sound to enter the edges of drapes or curtains unabated.


The cost depends on your number of windows, sizes, shapes, window treatments and ease of installation. Residential soundproof window inserts usually cost between $22 and $58 per square foot, including installation and tax. For example, buying three six-foot by three-foot inserts costs approximately 25% less per insert than buying one. Arched windows are about 15% more expensive than rectangular windows because they take more time to cut and install.

Prices for commercial soundproof window inserts vary even more (both lower and higher). For example, having more, larger windows will lower the cost of each insert; however, having windows that are difficult to access will raise installation costs. Our hotel installations are a good example of this – they have many large windows, yet limited access to rooms.

In most cases, we can install your soundproof window inserts within two to three weeks of receiving your 50% down payment. We usually install in one to two days, depending on volume and accessibility.

Less Expensive Than Soundproof Window Replacement


I live in a 1920’s bungalow in the Montrose area with beautiful original windows … however, they are drafty. You can see the curtains move. Not any more. I stand by them on cold days now and cannot tell it’s cold, which means I can leave my curtains open. One of my concerns was appearances, as I am all about not cheapening the historical look of my house. The Sun and Sound Window frames are so small, if I don’t point them out to visitors, they don’t realize I have them. I had two rooms put in as a trial and immediately called them back to do the rest of the rooms. Having these installed is much cheaper to what replacing the windows would entail in cost and time. The crew was efficient and fast. Took one afternoon each time to install the windows.

I can’t believe how much cooler the rooms are now with our window inserts, especially the ones that face west. One of them was set up as an office and I dreaded working in there during the day due to the heat. You either had to turn your air-conditioning thermostat down (for the whole house) or turn the ceiling fan on high, which blew your papers all around. Now it’s totally comfortable! An added plus is the sound from the street and a nearby freeway is gone

My biggest reason for buying window inserts was for sound. I live in a neighborhood with lots of children, and after they were installed, I was able to relax, read or watch TV without any distractions. Also, a tree had fallen and broken one of my windows this year. Not only did the soundproof window insert keep the broken glass from coming in to the house, it kept all of the rain out too. As far as the energy savings, they have paid for themselves many times over.

You have the power to solve your noise problems! I did and my condo is dead silent!

I have a one-bedroom on a low floor facing Sixth Street and the bars. My condo should be among the noisiest in the building, but it is dead silent with the soundproofing. I never hear cars/traffic and don’t hear most of the music. The only times I am slightly bothered are Friday and Saturday nights after 10/11 pm-ish when the music is playing and I am trying to fall asleep. The low base does creep through and is very noticeable… but that is easily solved by playing my own music. A loud fan or white noise machine will also work well. I do hear the occasional garbage truck pick-up slamming early in the morning, but that is about it. For living in the heart of downtown, I am extremely pleased.

I worked with Richard, who was excellent. He came once to take exact measurements and then again about 1-2 weeks after to install the windows. ProHome can’t fix my doorbell after three months and my Miele refrigerator still doesn’t cool, so it was a pleasure to have a vendor get it perfect the first time! Imagine that!! The windows also look great, which was very important to me. Based on all the noise complaints, this may have been the best investment I have made.
