If you have a broken, cracked window, you may be concerned about cold air coming into your home during the winter months. If a cold snap is ready to set in, you may wonder if there is anything you can do to temporarily cover the window. If so, use the following three-step guide to fill in the cracks and insulate the window against the frigid air.
Step 1: Seal The Cracks With Caulk or Super Glue
The first step involves covering and sealing the cracks to keep the cold air from leaking through. This can be done by using a caulking gun or by brushing super glue over them. Either one fills the cracks and forms a barrier over them.
Whichever you use, place the tip about a half inch from one end of a crack. Then, slowly pull it along the gap, filling it in as you go. Once you reach the end, extend the line about a half inch past it. This ensures the ends are covered so they do not let the cold air in. Repeat until all cracks are covered.
Wait about an hour after applying the first coat. Then, check for any openings. If you find any, touch them up with either caulk or glue, depending on which one you used. Allow it to dry, then go on to the second step.
Step 2: Place Quilt Batting Over The Windows
Once you have sealed the cracks, the next step involves forming the base of your window's temporary insulation. This is done by covering the glass with quilt batting. Its dense, fuzzy material creates an effective barrier, while its porous texture traps heat inside to further the protection against cold air from the outside.
For this step, you will need enough batting to cover the glass, plus an inch past the perimeter. This helps guard against cold air from leaking through. You will also need a measuring tape, scissors and two-inch clear postal tape.
Measure the width and height of the glass panes. Add an inch to each measurement, then use the numbers to trace a square on the batting, cutting along the lines.
Place the batting over the glass and secure it with the tape, making sure to cover any gaps that could let air in. Repeat for each piece.
If you do not have any quilt batting, you can substitute it for crumbled up newspaper. The paper from which it is made is dense, making it an effective insulator in a pinch. If you use newspaper, wad up each piece and secure it to the window with tape, making sure to cover the outer borders. Repeat until the entire window is covered, then go on to the next step.
Step 3: Cover the Batting With Cardboard
After you have placed the quilt batting, the final step is to cover it with cardboard. The cardboard not only holds the batting in place, but it also adds an extra layer of protection from any cold air that may leak through the batting. The thicker the cardboard you use, the better the protection. You will also need a measuring tape, scissors and the plastic tape used in the previous step.
Measure the entire window's width and height, adding an inch to each measurement. Then, trace the measurements onto the cardboard and cut it out. If you need to use more than one piece, measure them out so they fit the window.
Place the cardboard over the window and secure it around the edges with the plastic tape. If you have to use more than one piece, make sure you cover any seams with the tape to close off any spaces where cold air could come through.
While the above steps can keep the cold air from coming into your house, it is only a temporary fix for your broken window. For a more permanent solution, you may want to contact a company like New Jersey Siding & Windows Inc that performs window replacement to discuss your options.
