There are six ways by which this insulation technique can be applied.
- By Applying Window Film Insulation
Transparent window film comes in large sections that are pre-cut to the window size. The film attaches to the outside of the window frame with double-sided tape. Lightly blowing warm air over the film with a hair dryer tightens the film. It fills the space between double-glazed window panes, the dead air pocket created between the film and the window hinders air and thermal infiltration.
- By Adding Caulk to Gaps and Cracks
When there are cracks in the window sash or around the window that are 1/4-inch wide or less, we can squirt the area with water-based latex caulk. We can use silicone-based caulk for metal and glass surfaces. Caulk is inexpensive and easy to apply. All caulk periodically needs to be reapplied, especially if the window area is subject to expanding and contracting.
- By Adding Weather Stripping
Stationary parts in or around windows can be filled with EPDM, foam, or felt weather stripping. Movable parts of the window, such as the gap between the sash and the window frame, also can be filled with weather stripping on a temporary basis. It is simple to apply and will leave no residue or mess when removed. When applied to movable window parts, the window cannot be opened or closed.
- By Inserting Spray Foam
Large, accessible gaps around the window frame can be filled with polyurethane, expandable spray foam, and can be done if access is already there in the form of large holes or cracks. Aided by a long nozzle, spray foam can reach areas that we cannot reach by inserting fiberglass insulation by hand. Spray foam is difficult to control and can be expanded out of the wall cavity, onto the wall or floor, so we should be sure to purchase low-expansion foam.
- By Installing Energy Efficient Window Treatments
Window treatments like using thermal curtains that provide extra insulation tend to come in two forms - thick side-drawn draperies or vertically-drawn pleated (or cellular) blinds. The draperies are far thicker than ordinary ones and have tie-backs to hold them against the wall, further blocking air infiltration. The cellular construction forms air pockets that help maintain inside temperatures. During hot months, draperies with white plastic backings can bring down the home's heat gain by about 30%.
- By Using Draft Stoppers
Often used to block the gaps under doors, fabric draft stoppers, or draft snakes can also block the gap between the bottom of the window sash and the window frame. We can make our own draft stopper with long socks or by sewing fabric into long tubes. Rice, popcorn, or dried beans are used to fill the tube.
The Manchester Window Film is one best in the market for supplying and installing window films since 1933, serving both residential and industrial sectors.
