I was very skeptical that the inserts would work well on my skylight. My skylight is in my bedroom and faces a busy street. The noise was very bothersome, especially at night when I was trying to sleep. I was very pleased that the Indow inserts significantly reduced the noise and I am now enjoying a much quieter sleep environment. So thank you for making this all possible. I also want to thank Jacob for his helpfulness. Daniel also helped a great deal to ensure my contractor was taking the measurements correctly. It took a few extra times to measure my skylight but the end result was that the inserts fit perfectly and that’s pretty hard to do with the skylight being on a 16 foot slanted ceiling. All in all I am extremely happy with the results.
