Weatherstripping
Weatherstripping is used in homes, buildings, and automobiles to insulate against cold air and the elements. Weatherstripping is an easy way to insulate a home or other building, making heating and air conditioning more efficient and reducing energy costs by up to 15 percent.
Tension seal or v-channel weatherstripping is a self-adhesive vinyl folding along its length into a V shape. The shape of the material creates a seal by pressing up against the side of a crack. V-channel weatherstripping is durable, effective, and easy to install, as long as a flat surface is available.
For weatherstripping door or window stops, the top or bottom of a window sash, or the bottom of a door, rolled or reinforced vinyl or vinyl strip gaskets may be used. In general, this type of weatherstripping is fairly inexpensive and easy to install but will be visible.
Tubular rubber or vinyl strips can also be installed so that a door presses against them. They form a very effective air barrier, but may be more expensive and difficult to install than other forms of weatherstripping. Reinforced silicone, a tubular metal gasket attached to a metal strip, can be used in a similar manner as tubular rubber strips for weatherstripping windows. However, this type of gasket is similarly expensive and difficult to install.
Weatherstripping is also used in automobiles to keep heating and air conditioning systems effective. It also prevents noisy rattling and protects the inside of cars, trunks, and truck beds from water, salt, and dirt.
