How to Install Storm Windows

Here is a quick overview of how to install storm windows:

Installing Storm Windows in 7 Steps

1. Measure the regular window and the storm window at top and bottom for the width, and at both sides for the height dimensions.
2. Storm windows should be the same size as the window it is protecting since it is attached directly to the outside of the window.
3. Check to see if the window has pre-drilled screw holes. If not, drill holes spaced 12 inches apart in the storm window's flanges.
4. Once the window is secure in the opening, shim it on all sides, making sure it is level and plumb.
5. Secure the window in place by drilling in sheet metal screws in the pre-drilled holes. Then continue placing the remaining screws along the three other sides of the storm window. Do not over-tighten the screws since that can warp the frame.
6. Seal the exterior gap between the window and the window opening with caulk, taking into account the gap size and the weather exposure, and the expected movement of the window.
7. Finally, check to see that your new storm window operates correctly.

Take these simple steps, and follow the manufacturer's directions on how to install storm windows, and you should find that installing a storm window can take less than half an hour.
