We have used them for two different projects. They were easy to deal with and the inserts made a noticeable difference in traffic and leaf blower noise

Once again we have had a great experience with Innerglass. The product quality is perfect as always and Dave and Kimber and their staff are accommodating and very helpful as always. We highly recommend Innerglass.Dennis and Rita

Had them installed 7 years ago. Just as described, they're beautiful, invisible, and worked wonders for removing all the drafts from our really lousy windows. The installation was easy.
The Innerglass Window is a glass interior storm window that gives you the best of both worlds. It outperforms almost any replacement, yet maintains the integrity and beauty of your historic windows. It is mounted on the inside of the stops of the primary window, where it seals tightly, eliminating drafts and condensation problems. There is a concealed stainless steel springing system that requires no all around track. It conforms to the window opening, automatically compensating for most out of square conditions. For most applications the Innerglass Window is one piece for the entire opening, and pops in and out easily without tools. 10 minute install/ 10 seconds in/ 10 seconds out. Slider and Double Hung interior storms too.
