Block Drafts & Save Energy with Insulating Window Inserts

Poorly insulated windows don't just create uncomfortable chills, they also contribute to skyrocketing energy bills. Indow offers the perfect solution: innovative window inserts designed to stop drafts, improve energy efficiency, and enhance your home's comfort all year round.

The High Cost & Deep Discomfort Of Drafty Windows

The human body loses most of its heat from the head, hands, and feet. That's why we wear hats, gloves, and heavy socks when we're trying to stay warm in the winter.

Similarly, drafty windows are the #1 source of temperature loss in the home and the leading cause of wasted energy.

The average single pane window lets in a basketball worth of cold air every hour (double pane windows aren't much better!), which is why it can be so difficult to keep your home a comfortable temperature without running the heat all day.

  • Single Pane

    =

    A basketball's worth of cold air/hr

  • Double Pane

    =

    A softball

  • Indow + Single Pane

    =

    A marble

Imagine all that wasted energy just flying out of your poorly insulated windows and creating uncomfortable temperatures, high energy bills, noise pollution, and more.

If you experience any of those issues, that's a sure sign you need better window insulation in your home.

Insulating Your Windows Is Easy With Indow

Indow window inserts are a revolutionary solution for insulating your existing windows. These custom-made inserts fit snugly within your window frames, creating a secondary layer of insulation that:

  • Blocks Drafts

    Stops cold air infiltration in winter and hot air intrusion in summer, resulting in a more comfortable living environment.

  • Improves Energy Efficiency

    Reduces heat transfer, significantly lowering your energy consumption by an average of 20% and saving you money on utility bills.

  • Enhances Noise Control

    Acts as a sound barrier, reducing outside noise pollution an average of 50%, creating a quieter, more peaceful home.

Why Do We Use Acrylic?

Our acrylic window inserts create a barrier of trapped air to keep cold out and heat in. See why acrylic aces our insulation test!

The Affordable Alternative To Window Replacement

Indow window inserts are an incredibly cost-effective alternative to window replacements. When you factor in labor and inconvenience, window replacements can cost over $1,000 per window and still only reduce energy bills by 15%!

You'll also need to coordinate having contractors tear out your existing windows and the disruption to your day-to-day life. To make matters worse, the total costs of window replacements (including labor) aren't a great option for increasing your home's resale value.

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%.

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!!

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.

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.
