Compression Seals for Windows
We use compression seals for windows because it’s simply the best way to seal against drafts and noise. The silicone in our compression system stands up to heat and sun while nearly disappearing into the window frame. It was designed with a refrigerator magnetic seal in mind, but improved and simplified to make it stronger and easier to remove and reinstall.
How Indow Inserts Seal Windows
We use acrylic panels surrounded by silicone tubing to create our one of a kind window inserts. We use acrylic because it’s better for thermal and sound control than glass. We use silicone because it’s the best quality: long-lasting and resilient so it won’t lose its spring force over time.
Just like the Ove Glove, which uses silicone to protect your hands in the oven and keep the glove from being altered by heat, your window insert frames will stand up to the elements. They’ll be exposed to sun, heat, and UV rays for years, but will never change shape or lose their compression force.
“Silicone is almost impervious to UV radiation which exists in abundance in window frames, it’s highly resistant so it’s not going to lose its spring force over time. There’s something in engineering called compression set which is how much something loses its spring force when it’s squeezed for a long time and silicone has the very best compression set properties and durability properties.” -Sam Pardue, Indow Founder

Evolution of the Compression Seal for Windows
We originally had a magnet inside our tubing to seal windows. We wanted to improve the magnetic attachment system by accommodating for the acrylic panel’s thermal expansion and contraction while cleaning up the appearance by removing the need for a big metal frame on the window.
The plan was to make the frame of the insert act like a refrigerator magnetic seal. If you look at a refrigerator door, it’s a magnet surrounded by a compression seal. So, we were going to combine a magnet and compression tubing, just like a refrigerator magnetic seal.
VP of Marketing, Kristina Damschen Spina, installing the insert in the kitchen where the product was invented.
The initial prototype failed. It also didn’t look great. We removed the magnet and just used the spring force of the compression seal and worked! It looked so pristine in the window frame you could hardly see it. We accomplished everything we wanted: a near airtight seal for windows, a near perfect appearance, and no harm done to the window frame.
We didn’t stop there. We continued to innovate on the perfect way to seal windows, adding more compressive range and increasing the amount of spring force. We even added space in the tubing for a metal spine for added stability on large inserts. We’re constantly optimizing different aspects of our window insert from compression seals for windows to customer usability.
Seal Windows in Any Environment
We continuously improve our compression seal for windows to create the best draft- and noise-blocking window inserts possible. Together acrylic and silicone forge a perfect sound and climate control combination. They are both resilient, standing up to sun exposure without losing their effectiveness.
No matter what window issue you have, there is a window insert that can help. Take a look at all of our products to see what works for your situation.
Customer Reviews
I'm enjoying the units, however will need to wait until next year's colder weather to get a truer feel or read on how well they work - thanks
They work very well for my 3 Bedroom windows.easy to install.
I purchased two Indow window inserts for two west-facing bedroom windows. These windows are exposed to the hot afternoon sun, making it difficult to cool the bedroom, and there is considerable outside noise. The Indow inserts work great at reducing the outside noise and keeping my bedroom cooler. I absolutely recommend Indow window inserts.
Very professional from website to delivery and installation was well explained and easy. Noise reduction was quite noticeable and sealing from cold just as good if not better. Would recommend 100%.
Wonderful product
My husband and I can finally sleep all night without being woke up by outside noise! Indows are game changers if you live on a busy road, by a loud industrial business or just want a quieter inside environment. The customer service is pretty amazing too! Thanks Indow group for giving us back great sleep!!
fit perfect, weny in easyand make a diffrence with noise ,thank norbert
Easy DIY measuring, and an obvious immediate increase in warmth. Huge difference in a historic home with historic windows.
WE just took delivery of the two window inserts we ordered. they both fit perfectly. The most difficult part of the process was me trying to hold the laser measuring device still while taking the diaginal measurment! The Indow team was helpful and the ordering process was catch free. the finished product is just as they described. once installed, you can not even tell that they are there. I will warn you, if you have larger sizes they will come in a pretty large packing crate/box to protect them so be prepared. The only reason for 4 stars insted of 5 is they have just been istalled and we shall see how effective they are at reducing cold air, but they fit so snug that I anticipate they will be very effective. Just in time too, because our area is in a low temp/low wind chill pattern at the moment.
The Indow I ordered was a perfect fit. It looks great and is an extremely well made product. The ordering process was seamless.
Noise reduction by at least 50%! I cannot hear most car that drives by now. My bedroom is so quiet! Thank you!
Easy to order and install.
Window inserts help with sound since I live facing the street and the highway
This is a 5 star company from beginning to end. I purchased the I inserts in 2017 because the bedroom on the second story faced the street. These are very effective for street noise. Noticed a problem on one of the windows recently and they quickly took care of it due to their warranty. Customer service personnel are very helpful. The price of the windows was acceptable for top quality of sleep and less noise during the day
Recently purchased the acoustic window inserts for a couple of old windows facing a busy street and they've made a huge difference in terms of noise reduction! The measuring process was relatively easy with the laser measuring tool that Indow sent and the windows were delivered faster than expected. Martin was easy to work with and we would highly recommend Indow to those looking for window inserts.
