Building owners and developers applying for a Federal Rehabilitation Tax Credit – also known as the Historic Tax Credit – are urged to reglaze, rebuild and restore historic windows instead of replace them. They can use Indow inserts to make those original windows perform like high-performance double-panes.

New Window Technology Makes Buildings Sustainable
Saving energy doesn’t require replacing historic windows. A U.S. Department of Energy study found Indow inserts saved 20 percent in heating and cooling costs in a century-old Seattle home.
Increasing the energy-efficiency of their built environment is an important sustainability goal for many businesses. In addition, existing windows – especially wood windows from trees hundreds of years old – have significant amounts of embodied energy. Indow’s clean-tech inserts allow companies to keep historic windows out of the landfill by making them perform like new double-panes.
Original single-pane windows not only let in drafts, they let in noise since sound vibrations move anywhere air does. This can be a particular problem in historic commercial districts with pedestrian and vehicle traffic. Indow window inserts can reduce outside noise by up to 70 percent* without changing the appearance of the window.
*We want to ensure our inserts help solve your noise problem. Overall noise reduction depends on the amount of noise coming through your walls, ceilings, floors, doors, and existing windows. Noise reduction will be less when placed over double-pane windows. Read our full Noise Reduction Sheet to learn more.
