About Indow® Window Inserts

Indow Window acrylic inserts are edged with a soft, patented silicone compression tube that presses into the interior of your window frames to seal out drafts.  The typical installation doesn’t require any hardware; the compression seal keeps the inserts in place.

Unlike other solutions for insulating drafty or noisy windows, Indow Window inserts are custom-made using our proprietary laser-measuring system. Here’s why this matters: since homes and buildings settle over time, most windows are not square. To seal window drafts and noise out effectively, we custom make our insulating window inserts to be the exact shape of your window frames. Our laser measuring system ensures each insert fits its window just right.

We can design inserts not only for rectangular shaped windows, but we can accommodate virtually any shape window including:  Circle/Round, Arch Top, ½ moon, trapezoid, elliptical, as well as other shapes.

Why Choose Window Inserts

Not only do Indow Windows work as advertised, but they are also a cost effective solution for your window project.  Are you searching for a the perfect blend of comfort, energy savings, and noise reduction?

Inside Storm Windows with Guaranteed Precise Fit:  Indow Window inserts are made out of high quality acrylic glazing and edged with our patented Compression Tube. The tubing squeezes down when pressed inside your window, holding the insert securely in place without a mounting bracket. Every insert is custom made according to precise, laser measured dimensions of your window frames, for a perfect fit, every time.

Seals out Noise and Drafts:  Once installed, Indow inserts seal out cold drafts and hot air, giving you all the comfort and energy efficiency of high-end replacement windows and significantly outperforming them when it comes to noise reduction.

Easy to Install—No Hardware Required:  Indow Window inserts are like inside storm windows, but easier to use and non-damaging to your window frames. You can easily pop your Indow inserts out whenever you want to catch a fresh breeze that’s blowing by.

Blends Into Existing Windows, No Permits/Approvals Required:  Indow Windows virtually disappear from view; both from inside and outside.  And the best part:  they do not require building permits, homeowner/condo association approval, or approval from your town/city, even if your home is in a historic district. 

Any Shape or Size:  We can design inserts not only for rectangular shaped windows, but we can accommodate virtually any shape window including:  Circle/Round, Arch Top, ½ moon, trapezoid, elliptical, as well as other shapes.  Large, oversized windows?  No problem, Indow Windows can be made to any size.
