May 19, 2022 Update: We have decreased our lead times to 9-10 weeks.

We have been able to reduce our lead times by additional three weeks thanks to bringing new suppliers online for our various parts, as well as increasing staffing to cover outages.

Our goal remains to reduce our lead times to pre-pandemic numbers to bring comfort and quiet to your space more quickly.

August 25, 2021 Update: Our lead times are currently 14 weeks. We have successfully moved into a new factory which is helping us become more efficient every day.

Our new factory also means that we will be protected from future supply disruptions because we have the space to store more on site. We’re in the process of bringing on new suppliers so we have material redundancies which protect us and our customers even further.

The move to our new space isn’t just about the supply chain issues. We are now able to set up our production on one floor, whereas previously it was split between two floors. We are now hiring new production team members. Our new production set up and our current hiring efforts are helping to get orders out the door more quickly. We also have the ability to stay open on hotter days because of the size and airflow of our warehouse.

June 11, 2021 Update: At this point we are all feeling the sting of supply chain disruption, whether it’s missing our favorite summer activities or our favorite coffee beverage or our favorite window insulation. Nothing seems safe from these global shortages.

“Shortages and price hikes are affecting the entire retail sector. Bikes, cars, meat, cheese, and even ketchup are all becoming more expensive, in part thanks to disruptions to the global supply chain from COVID-19, plus a shipping container shortage and port congestion. These factors created what experts called a “perfect storm” in global transportation.” -Insider

Things are getting better! Though experts say the supply chain issues won’t be entirely cleared up until 2022, things are improving. The Executive Director of the Port of Los Angeles says “all the metrics are moving in the right direction” and April 2021 was the busiest month for port traffic since they began tracking container imports 19 years ago.

The White House also released their 100-day review of the supply chain after President Biden signed an executive order investigating supply chain delays. Container volume is expected to increase each month over the next four months.

We will continue to keep you informed as we work diligently on solutions.

Throughout the pandemic, people have been experiencing more noise and discomfort, which has led to an increased demand for our products. We are happy to provide a solution, but COVID-19 has also wreaked havoc on the supply chain, sending shipping containers to the wrong part of the world, clogging ports as new protocols slow things down. We have been working hard to absorb these supply chain issues that have affected the entire world.

Our team is building and shipping inserts trying to impact you as little as possible while we wait on inventory from our suppliers. Because of this, production times are currently approximately 14 weeks.

We’ve been working hard to absorb the supply chain issues for months. At the start of the pandemic, some supplies went from a 2 day wait to 9 months! We were able to continue without any disruption until very recently. As you can probably imagine, some of the pieces that go into our inserts are proprietary and sourcing materials isn’t an easy task. We appreciate your patience while we continue this pursuit.

Should I place my order now? We say yes! It will guarantee you a spot in line once our production levels are back to normal.

Our factory is still fully operational and we haven’t needed to lay off any staff due to the pandemic or the supply chain issue. The lower inventory levels have caused slower production and output, but we are waiting and ready to handmake inserts once all materials have arrived.

Thank you so much for your patience and desire to support a small company. If you have any questions about your order, or about this production delay in general, please reach out to us directly. We want to help in whatever way we can.

The inserts provided immediate results for the better. The inserts a virtually invisible which was better than expected. The biggest challenges were getting the accurate measurements which I Dow was helpful with and repositioning the blinds. Everything has worked out. We are planning to do this with other windows

We were excited to receive our Indows, but once we got them in, we were blown away! They match our woodwork almost perfectly. Installing them was far easier than we had anticipated, and we were immediately impressed by the noise reduction, as well as the ability to reduce the impact of the windows on our indoor temperature! Couldn't be more pleased and very excited to be able to add "custom" shapes for the top of our lancet windows.

The acoustic indow window worked better than I expected at blocking out noise. The only thing I didn't like was the shipping company (T-Force Freight). The shipping company was difficult enough that I decided to rent a U-Haul and pick it up at their warehouse.

Indow solves my noise problem due to highway traffic. I recommend this company for noise reduce solutions.

The process was simple and easy. I was a little nervous having to measure everything myself...but I got the inserts and they fit in our windows perfectly without any hassle. 1000% recommended.

As always with internet purchases, I was holding my breath on my recent purchase of inserts! However, everything suggested by everyone I spoke to via telephone, email and text, was verified when I received and installed my inserts!!! Nothing short of phenomenal; fit, sound deadening qualities, (yet to discover energy savings), and customer service is excellent!! I highly recommend this company and product!!

Good quality window inserts. Easy to install. Unfortunately, doesn't do much to block road noise that I was hoping it would help with. Website is clear on the uses so I can't say it was false advertising, just buyer error.

We ordered 4 Indow Window inserts to see how they worked on our steel casement windows. We are very pleased with the fit and finish, and especially the improvement in wintertime comfort. Steel casements present challenging issues when trying to improve efficiency. The only downside for our installation is it required the removal of the locking and operating hardware to work in concert with our window treatments. The attached photo is during installation with Indow inserts installed on the two left pair; not yet installed on the two right pair. Pretty minimal visual difference! I'm now ordering 17 more inserts for the rest of the house.

Our acoustic window inserts have definitely reduced the amount of street noise coming into our apartment. While we can still hear the train as the engines pass by the noise from the train cars is very muted. Likewise we still hear the drunken club patrons yelling, but it no longer seems like they are in the room with us. Our big negative would be that the blinds we enclosed in the space between our single pane and the insert melted and warped within the first week. I don’t think there was any mention in the directions about the possibility of heat build up and potential consequences. That might be good for people to know.

Finally, a solution that doesn't break the bank and allows you to keep your existing windows. We bought ours primarily for additional soundproofing as our builder used dual-pane glass. It makes a measurable difference - 20 dB. The bonus is the insulation value. It's been a mild spring and our main bedroom at the front of the house facing the morning sun is much cooler. I suspect it will be warmer in winter as well. If you follow the self-measure and installation instructions to the letter, they go in easily. We have floor-to-ceiling windows, so we had massive inserts, but it was still manageable for two people.

The measurement process was overly complicated - I understand the desire to get a tight fit into not perfectly square windwos, but a 17 page manual for something you can accomplish with math felt unnecessary. I also found the interface to be a bit challenging to work with when inputting fractions that necessarily had to be rounded but the system didn't like my entry. Otherwise, the inserts themselves fit well, very tight, noticeable noise reduction. I am so satisfied with them that I am considering placing another order (depending on whether I want to also spend the money to change window treatments).

What a great option for old homes with drafty windows! Our home's windows are so drafty that the curtains in our bedroom would move/blow when it was windy out. The communication with Indows was excellent, and our questions were answered promptly. We thought the measuring process would be a pain, and we were worried we would not be accurate enough, but the kit they sent along with the instructional videos made it very easy. The Indows were delivered in a large wooden crate, and they made it through shipping unharmed (just some dirt marks on the silicon tubing, most of it came off with Castille soap, but some dark smudges did remain on the white tubing--our only disappointment). Our windows are huge, so we installed the little safety chain provided and inserting them was a 2 person job. There was a little bit of a learning curve with the first Indow, but we can take them in and out fairly easily now. The fit was perfect, and we noticed a difference in the temperature of our home right away. Our house stayed warmer, our furnace ran less, and our curtains are no longer blowing in drafts. The product looks great, and blends right in with our woodwork! We will definitely order more for the few windows we didn't do, and we would recommend this company and product to anyone.

They really work! While I still hear traffic (mostly trucks and motorcycles) normal car traffic is virtually silenced. I'm still not able to sleep in the room because we get so many trucks I am able to use this room as an office space now, which was my goal. This room was once the noisiest room in my house and now I enjoy coming up here to watch tv. Thank you!
