Value proposition

Cleantech company making window inserts to provide comfort, quiet, and savings to residential and commercial spaces.

Indow's custom window inserts simply press inside existing window frames to make old double-panes perform like new for a fraction of the cost.

Indow inserts do not require an internal mounting bracket and have a low profile design that almost disappears when installed. They block cold drafts and hot summer air, reduce energy bills and quiet outside noise coming through windows.

Indow inserts are easy to install and remove and do not damage existing windows.
