How They Work


Polyolefin film (blow dryer plastic) is taped 3" to 4" from the original window, making the application ineffective at creating a dead air space. This allows for too large of air pocket permitting too much air circulation, reducing energy savings.

Our panels fit to less than 1.0" to the original window, greatly improving the dead air space efficiency. Like a 'cork in a bottle', the panel has a surround compression gasket that snugs to your window frame.
