Installation Instructions For Internal Storm Windows?

To install a new storm window, cut all four sides of the frame at a 45° angle on the ends, ensuring the longest point of the mitre is equal to the longest length you measured. Lay everything out on an asse, and consider variations for installation. Storm windows are designed to fit snugly inside interior window frames, optimizing their insulating and sound-reduction qualities. Interior storm windows are easy to install, and it is essential to determine the ENERGY STAR climate zone of the house and select a storm window that is ENERGY STAR rated for your climate zone.

Installing interior storm windows is a simple and effective way to improve your home’s energy efficiency and protect your primary windows from the elements. To install a storm window, center the window in the opening, lay a generous bed of caulk around the sides and top of the storm bed, and pull apart the mounting strip and trim piece that snaps in to hold the window. The joining mullion can be used either vertically or horizontally, but never in both directions. Screws are visible from inside and outside of the storm.
