Block Heat, Save Energy, and Stay Cool

Do You Have Trouble Keeping Your House Cool?

Is your energy bill astronomically high in the summer? Running the A/C but not feeling comfortable results? Searching for how to insulate windows to keep heat out?

When the weather is hot, heat infiltrates through your windows and your AC has to work on overdrive, leading to high energy bills and a house that is still too stuffy and warm. 

How To Insulate From Heat & Stay Cool All Summer

The problem could be that your windows are underperforming – leaking the cool air out and letting the hot air in.

It’s time to give your A/C a rest by upgrading your windows. 

Insulate and seal your windows with Indow window inserts – the most affordable way to keep your house comfortable and quiet (and save money) all year long.

Sealing your windows is an important part of protecting your home against hot weather. Indow inserts create an airtight seal around your windows that insulates your home and keeps the cool, conditioned air inside. Our inserts stop heat from coming through windows while still allowing natural light in.

Additionally, Indow’s inserts help homeowners save 20% on their yearly energy bill, reduces outside noise by up to 70%, blocks pollutants like smoke or pollen from infiltrating through your windows, and helps regulate your home’s temperature all year long.
