The Innerglass Compression Window is a vinyl framed, glass interior storm window that mounts on the inside of your primary window using Compression-Fit technology. These storm windows seal tightly, eliminating all drafts, condensation, and outside noise.
The Compression-Fit Advantage eliminates the need to install a track for the window to sit in, thus providing an airtight fit - even for windows that are not square!
Innerglass windows are quick and easy to install. No carpentry is involved. These windows do not disturb the integrity of your existing windows.
