Sound Proofing
Noise can be a big problem for tenants and guests. Hotels, multi-family apartments and office buildings can lose occupancy and money if their guests cannot sleep or concentrate.
Learn how our acoustic grade inserts can reduce noise as much as 70%.
Please see the the case study of the Commonwealth Hotel in Richmond.

This short video demonstrates how Indow window inserts reduced traffic noise to a whisper.
Energy Savings & Comfort
Improve the comfort of your guests and tenants by eliminating drafts while lowering energy costs as much as 20%.
Indow inserts can make old single-pane glass windows perform as good or better than modern double-pane glass windows.
Please see this case study of this Richmond apartment building.

Historic Preservation
Retain your building’s aesthetics and historical charm while improving its efficiency.
Our inserts are ideal for adaptive reuse projects as they preserve the look of historic windows while improving your building’s efficiency.
These can be helpful when applying for historic tax credits.

Condensation Reduction
Condensation can be a big problem for building owners. This can lead to paint and wood damage and even unhealthy mold.
Indow window inserts create a barrier so moist warm air from living areas cannot reach the cold glass and condensate.
In most cases we can greatly reduce or eliminate condensation problems.
