Block drafts and noise at the same time

Facility managers know the value of soundproofing an office. They’re the ones tenants and employees complain to when outside noise like construction, trains or traffic makes it hard to concentrate and work. Since most noise enters through the windows, it’s easy to reduce it – and block cold drafts – with Indow inserts.

The benefits include:

  • Eliminate distracting noise for staff and office visitors.
  • Stop the need for space heaters by increasing thermal comfort.
  • Average 20 percent savings on energy bills.
  • Create a greener office.

Soundproofing improves business outcomes

Immersion Active’s employees often had to pause conference calls when fire trucks and other traffic drove by their Frederick, Maryland building because the noise came straight through the single-pane windows. This changed after the company installed Indow inserts.

“Now people gravitate to those rooms because they’re so quiet compared to the other rooms,” said co-founder and president David Weigelt.

Commercial window inserts are available in Acoustic Grade, which reduce outside noise by up to 70 percent when placed over single-pane windows. When placed over operable double-pane windows, the inserts reduce noise by 12 dBA, equivalent to a 50 percent reduction in noise and an STC rating of 42-45.*


The Ballston Tower’s tenants started to increasingly complain about construction noise during the redevelopment of the Ballston Mall in Arlington, Virginia. Then the property manager installed Indow inserts.

“All the complaints we were getting, stopped,” said Jacob Sickels. “From our point of view, they worked perfectly.”

Uncomfortable employees are distracted employees. With their airtight seal, Indow inserts create a space conducive to concentration.

*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.


The ROI of saying no to window replacement

Arlington County government in Virginia used Indow inserts to convert an office building with fixed windows into a homeless shelter.  Replacing the windows would have cost more than $1 million and required exterior scaffolding. For less than 20 percent of that, the county installed 304 window inserts and said goodbye to plastic sheeting and expensive space heaters that are dangerous if left on. The 50-year-old single-pane windows instantly performed like new double-panes.

Don’t take our word for how well these inserts insulate. The thermal imaging photos below show what they can do for your building. A U.S. Department of Energy study found Indow inserts reduced energy use in a Seattle home by 20 percent.

Soundproofing increases market value

Before Foto Crush agreed to rent space in the Olympic Mills building in Portland, the marketing firm asked the property manager to soundproof the office to block the train noise. Instead of replacing the windows, Mike Larkin installed Indow window inserts, which also made the space more comfortable by eliminating drafts.

“We realized that if we fixed our window problem we could lease the space for market rates… instead of leasing far below market,” said the Elliott Associates broker and property manager. “The return on the investment has been outstanding – and we like happy tenants.”
