Older homes often have flimsy, single-pane windows that just don't cut it when it comes to energy conservation (
figure A). While insulated replacement windows offer strength and save energy, Storm windows (
figure B) are less costly, protect just as well and are also great insulators. Try these tips for installing storm windows.
- Begin by measuring your windows. Take measurements on the exterior of the windows, between the facing (figure C). Measure width at the top and bottom of the facing, and measure vertically on both the left and the right. Use the smallest measurements to ensure the storm windows fit inside the facing.
- Once you have storm windows to fit, begin by drilling pilot holes (figure D). Start by coming four inches out from a corner, then space holes about 12 inches apart. If your storm windows have grooved frames, drill through the outermost groove.
- Attach windows using self-tapping screws. After all the screws are in, caulk around frame to seal any gaps. Start at upper left-hand corner and go down then across the bottom (figure E). Then go back to the corner and go across and down the other side. This works best for right-handed people, so if you're left-handed starting in the upper right -hand corner may be easier.
- To prevent water from becoming trapped inside the storm window and causing problems for the windowsill, drill a couple of drainage holes. From inside the house, raise the windows and drill some holes level with the sill through the main frame.
