ABOUT THE ENERGY EFFICIENT HOME IMPROVEMENT CREDIT
Indow is a certified manufacturer of “eligible building envelope components” (window inserts) that may qualify for the Inflation Reduction Act tax credit pursuant Section 25C of IRS Notice 2022-48.
To qualify for this credit, your window inserts must be installed in a dwelling unit located in the United States and the order must be shipped in the tax year you are claiming the credit for. $1,200 is the maximum allowable credit for all qualified energy efficiency improvements in a single tax year.
Due to the complexity and uniqueness of tax law, we recommend consulting a tax advisor if you are uncertain about your eligibility for this credit.

I ordered the "acoustic grade inserts" for my bedroom to reduce road noise. They work exactly as advertised. Are they soundproofing? NO. Do they reduce noise to acceptable levels? YES. Compared to other solutions on the market (replacement windows, glass inserts etc) this is much more affordable. However, if you are looking for actual soundproofing, you need to spend more money and get something else. As a bonus, the inserts are tight fitting and have reduced drafts.
