STEP 3. Windows - Fixing Cracks
1.Paint the crack with nail polish. For small cracks in the glass, apply several coats of clear nail polish directly over the damaged area. Wait until each coat dries before applying another.
Note that this is only a temporary fix. The polish should seal the crack and prevent it from spreading for several months, but it will eventually wear off. Cracked window glass will need to be replaced.
2.Use weather-seal tape. Cut a small strip of clear weather-seal tape and place it directly over the crack in the glass. The tape should last for several months and prevent air from flowing through the crack.
As with nail polish, weather-seal tape should only be used as a temporary fix. You'll eventually need to replace the cracked window glass to prevent the crack from getting worse.
STEP 4.Sealing the Entire Window
1.Apply window insulation film. Trim the film down to size, if necessary, then stick it to the inner glass of your window using double-sided tape. You'll also need to shrink the film with a hair dryer for an improved seal.
l This is another inexpensive and simple solution, and it's as simple to remove as it is to apply. You may wish to soak the tape in rubbing alcohol before peeling it away, though, to minimize the risk of peeling away any paint or leaving any sticky residue.
l The film will create a noticeable haze over your window. Light should still shine through, but it may not be the most aesthetically pleasing option.
2.Stick bubble wrap onto the window. Spray the window with water, then press a sheet of trimmed bubble wrap directly onto the wet glass. It should stick without difficulty and remain in place for several months.
l Bubble wrap can be even cheaper than window insulation film. Opt for bubble wrap with large bubbles since it tends to insulate better than the smaller bubble type.
l Trim the bubble wrap so that it slightly overlaps the seams of your window. When applying it to the window, the bubble-side should face the glass. If desired, you can apply a double layer of bubble wrap for even better insulation.
l If the bubble wrap won't stick to your window on its own, you may need to use double-sided tape to help it stay in place.
l Bubble wrap will block the view from the window, but it should allow light to come through without difficulty.
l To remove the bubble wrap, simply peel it away, moving from one corner to the diagonally opposite corner. The bubble wrap itself usually won't leave any stain, but you may need to clean the window to return the glass to full visibility.
3.Layer shades and curtains. Install cellular shades over your window, then fit heavy curtains over the shades. Either option on its own should provide considerable insulation, but pairing the two together will help even more.
l Cellular shades are also known as honeycomb shades due to their unique structure. Folds of fabric create layers of air pockets, and these layers trap more air than standard shades can. These shades allow light to filter in and can be custom-fitted to match the dimensions of your windows, but they can also be fairly expensive.
l Heavy curtains have an elegant appearance, but they can also be somewhat expensive, and they'll only insulate your windows when drawn closed. Unlike cellular shades, curtains will block out the light when closed. 4.Install window insulation panels. Mount the aluminum frame of the window to the interior side of your window. Each frame has weatherstripping around the perimeter, and that weatherstripping should seal the existing window. l When you purchase a window panel kit, you should get all the necessary components and specific installation instructions. You won't be able to custom-fit the panel, though, so make sure that the dimensions of the aluminum frame match the dimensions of your window before purchasing the kit. l The panel creates a secondary air pocket in between it and the existing window, and excess air flowing through cracks and leaks should get trapped inside that pocket.
