Custom Window Inserts Create Comfort
Drafty windows make your home cold in winter as heat flows outside. In summer, they force your air conditioner to work extra hard — leading to high energy bills all year. Window replacement is one solution, but it can be expensive and disruptive. For homes built before 1978, it also carries the risk of lead paint contamination. Insulated home windows make a huge difference in comfort and energy savings and can be as easy as installing window inserts.
Whether you’re trying to keep historic windows to preserve the value of your home or want to enhance the performance of newer windows, Indow inserts will regulate the temperature to make you comfortable year-round.
How to Seal Window Drafts Effectively
Our acrylic inserts are edged with a soft, patented silicone compression tube that presses into the interior of your window frames to seal drafts. You’ll feel warmer in winter and cooler in summer, while saving up to 20% on your energy bills.
Unlike other solutions for insulating windows, Indow inserts use a proprietary software, Measure by Indow. We designed this to check the accuracy of window measurements. Going through this process ensures a precise, snug fit for your custom window insert. Why does this matter? Since homes and buildings settle over time, most windows aren’t square. To seal window drafts effectively, we custom-make our inserts to be the exact shape of your window frames. Our measuring system ensures each insert fits every window just right.
Our patented compression tubing allows you to easily install or remove your inserts without damaging your existing windows with a mounting bracket or track system. The thermal acrylic increases the surface temperature of your existing windows, which raises the overall room temperature and lowers your energy bills. Another benefit? Due to the airtight seal, Indow inserts often reduce or eliminate window condensation.
