Double Glazed Interior Storm Windows

We manufacture double glazed interior windows at our facilities in S.W. Wisconsin. These interior storm windows are constructed using an attractive aluminum frame which is powder coated and painted (3 color options) and this material is 15/16" X 3/8" roll formed .032 aluminum. We use steel corners, not plastic, and these corners are invisible to you as we miter the frames. The glazing film is a very special German film which is 4.3 Mil. thick, crystal clear, UV stabilized, -33 degree and distortion free. Around the entire outer perimeter of the frame we attach a high quality foam weather stripping which will collapse when you install your interior storm window, as it collapses it forms a perfect air seal and also holds the window securely in place even if it is an overhead skylight. We have designed these to last you for decades and thanks to the double glazing your existing windows will immediately become near Energy Star efficient. The double glazing is the secret to the energy efficiency, you are creating two new dead air pockets with our windows, one from your window to the the interior storm window and then the window itself has a 3/8" dead air space built into it between the two layers of glazing film. These two dead air spaces are super insulators and in the world of energy efficiency when it comes to windows one layer of glazing only stops a draft....... two layers of film will insulate, inhibit condensation, stop drafts, cold areas in rooms near windows and address heat loss or gain. We can build almost every size and shape. 563-542-2134
