What are Indow Windows?

Indow Windows are thermal window inserts that press into your window frames to give you money-saving, double-pane window performance but at a much lower cost.  Indow Windows increase comfort by blocking cold winter drafts and can save you up to 20% on your heating bills*. 

Indow Windows are like interior storm windows, but much easier to use. They are extremely easy to pop in and out and provide an airtight seal, significantly reducing air leakage and outside noise. 


Best of all, Indow Windows almost disappear when installed, letting your home's beauty shine through.  Their low-profile design blends in with the window frame so you can maintain that classic look of your original single-pane windows.
