Customers report an immediate improvement after installation, noticing that space heaters were no longer needed and that the inserts keep cold air out and hot air in. The inserts are fantastic quality and fit perfectly, with fast shipping and packaging that made installation take all but a minute. The price is very favorable. The company provides excellent customer service, helping customers understand what they need for their project and how to set it up the best way, even if they don't sell the specific product. Customers highly recommend purchasing these inserts for windows, skylights, porches, and doors, noting they are easy to install and will be easy to remove. They keep pollen out in the springtime and make a difference in the heat.
Thanks Eric & co. These are quite thin, but they definitely work! Glad I decided to pick some up. Makes a difference with my skylights in this heat. I used silicone to fill in any gaps and ensure they stay in place
Excellent customer service. Even though they didn’t sell the product I was looking for, they helped me understand what I needed for my project and how to set it up the best way.
Ordered window inserts from them a couple years ago though and they were fantastic quality.
I purchased these window inserts for 3 skylights and 2 windows in December 2023. We have high-end windows that we purchased about 5 years ago. Despite the window quality, there is always some leakage. We noticed an immediate improvement in the three rooms where the inserts were installed. Space heaters were no longer needed. The price was very favorable. I highly recommend purchasing these inserts.
