did not perform as expected. My Indow windows inserts did not perform as expected. The constant road noise from traffic is still annoying, and there is not a tight seal, I can see space between the wall and window insert corners, also there is a condensation build up on the bottom. The wait for the took for the insert arrive was about three months, but I did received periotic emails on the order status, and Mr. Reed gave great customer service.

Cut bedroom decibel level in HALF. Impressed. 5 stars for a great product. I live next to a busy highway and it's been incredibly disruptive to my sleep. Indow has cut the decibel level in my bedroom by HALF. Impressed. My only gripe: Shipping took about a month, and instead of just saying "shipping takes a month" (which I would have been completely fine with) the company auto-sends an email after purchase saying "We have worked hard to absorb the supply chain issues that have affected the entire world". This is unprofessional and annoying and as dated as listing your pager number on a business card or fax number on your website. Companies need to stop blaming acts of God for your poor customer service department or slow response/delivery times. Deal with things out of your control, and stop making excuses because of them. (Especially THREE YEARS later)

I have a bank of three heat pumps right… I have a bank of three heat pumps right outside of my bedroom/office window which are noisy. It made sleeping and working in the room difficult. The Indow inserts, combined with padded drapes, make sleeping and working significantly easier. The step-by-step process was relatively simple, and the sales rep, Brian, was helpful. Thank you Indow!

New windows are really expensive and… New windows are really expensive and can ruin the look of a house. These Indows are not the cheapest inserts on the market, but they are really clever, do not require permanent frames, are made very precisely (none of my hundred year windows were still square) and our home was a lot warmer this winter because of them. Replacement window salespeople promise the world in terms of ease and energy savings and rarely deliver. These are such a simple alternative that do just as good a job.

Super easy to install I ordered these for a home which had lost all of its original interior storm windows to foolish previous owners. The measurement kit was easy to use and all of the windows arrived intact and fit properly. I probably spent more time getting them out of the box than I did installing them. I purchased mine for additional insulation and I look forward to the reduction in cold drafts this winter.
