I am pleased to join the chorus of great satisfaction in our Indows! And to echo the oft-repeated claim that the noise reduction benefits were profound and pleasing! Comfort has improved, and while we are still in shoulder months between heating and cooling, I feel we actually delayed turning on our energy-eating air conditioning because our Indows have helped us maintain comfort later than would have been the case. Finally, I will note how perfect the Indows solution is for our home located in a historic district of town. Our Landmark District code prevents window replacement until our historic, single-pane windows are "beyond repair." Our windows allow us to maintain aesthetic charm without sacrificing comfort and insulation performance. The Indows installed easily and fit perfectly. I would note that the largest, measuring 70 in wide and 77 in tall seems to be at the far edge of how big I want a single-piece Indow to be--it was a little challenging to get it seated exactly where we wanted. But like the other 12 Indows we installed, it has sealed nicely. And sitting at my desk looking out of that big West-facing window is a joy and now, much more comfortable. That brings to mind one more big benefit--when your windows are more comfortable to sit near, you get to use more of your square footage in your home. No more having to avoid the hot or cold spots near windows!
