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.

Indow inserts were easy to measure, order and install. They've provided great insulation for old single-pane and stained glass windows in an antique home. We can significantly feel how much better the home holds heat.

I ordered two Indow inserts for my home. They are doing a great job, entirely happy with them and the ordering process.

I can't say enough good things about this product and company. Our house is 101 years old and the sidelites next to our front door are single pane ancient wavy glass which means when it gets very cold (Chicago temps) we can have an inch of frost covering the INSIDE of our windows. I was desperately searching for a solution so our front vestibule was not so cold and a friend recommended Indow. The process could not have been simpler and the temperature difference it has made is off the charts.

I have several historic single pane gridwork mullion windows. They're beautiful but have almost no thermal protection. Indows proved to be the perfect solution to preserve these windows while getting the thermal comfort we need. They were easy to install and work perfectly!

Amazingly easy to install even the safety chain holders. I. Noticed an immediate sound level difference and the room atmosphere became more solid feeling and pleasant. They also gave an insulating feature to the window drafts are non existent! The house is 50ft off a State highway that is heavily traveled in warmer months I'm confident the indows will handle it. I'm very pleased!

We ordered the acoustic inserts to help with road noise, and we've been sleeping so much better with them!

We used the windows inserts in our skylight. They are great! They the horrible drafts and noise out and were cost efficient. My only comment would be to provide better measurement and installation instructions for skylights specifically. It took us a lot of guessing and research to measure and install because skylight directions were not provided and the windows install guide doesn't always apply to skylights. Other than that though great product and I would buy again!

Our home was built in the late 1800s and we have spent a lot of money over the last 20+years restoring it.We did not want to replace the windows with modern windows because of the cost and originality. But the single pane windows come with a price also. the main reason we purchased the Indow window inserts is because of the condensation on the inside of the windows.We would literally have a take a towel and wipe them down every morning in the winter. There would be a puddle on the sill,and wood and water dont get along to well. SO we looked into the best solution to our problem and found Indow. Was reluctant to spend that much money but am super glad we did!! They have been installed now for over two months and our condensation problem has been virtually eliminated.!!! AND our furnace does not run as much as it did before. Over all it was money well spent!! The process was a little scary at first but they have a simple formula. And our contact person,Reed was awesome. Answered any questions i had and was always available.

Used to block interior side of a garden window in the the kitchen. Without insert, cold air literally poured into the kitchen making a winter jacket almost mandatory when preparing meals or washing dishes

Highly recommend! The team (Brian) took time to help me figure out the best solution. They were made and delivered faster than expected. It was very rewarding to install them because I could feel the cold air get squeezed out as they went flush against the single pane of glass. Solid quality and great fit.

My inserts fit beautifully into my 125 year old windows - many of which were 5 feet tall. Easy to unwrap and install. Great product and even better service! I liked the process of measuring the windows with a laser measuring tool which was easy to use and precise. The product came in good condition after shipping across country and was well marked. The customer support was excellent.

Received our Indow Windows and can tell they are blocking a lot of the noise we could hear. Right now the weather is mild, but hoping to notice a big difference when the summer heats up. Our house is in a historic district and we cannot change our windows. They are very drafty and thin glass. We only ordered two, but we are in the process of ordering for four more. Love that we don’t need to drill holes or anything and they just pop right in.

Every thing arrived in perfect condition, thanks to the very secure packaging. Windows fit as expected, although quite tight. After installation we noticed that the cold drafts were gone and the room felt a lot warmer. We are very satisfied with the product and the result.
