Weather Stripping and Caulkingarrows

If you feel a cold draft around doors and windows, heat is being lost – and money is being wasted.

Installing weather stripping around windows and doors that lead outside or to unheated areas of your home is an easy and effective way to save on energy costs. Be sure to choose weather stripping that will withstand the friction, weather, temperature changes, and wear and tear associated with its location. The weather stripping chosen should seal well when a door or window is closed and allow it to open freely. Weather strip and insulate the attic hatch or door to prevent warm air from escaping out the top of your house.

Choose an appropriate product for each location. Felt and open-cell foams tend to be inexpensive, susceptible to weather, visible and inefficient at blocking airflow; however, the ease of applying these materials may make them valuable in low-traffic areas. Vinyl, which is slightly more expensive, holds up well and resists moisture. Metals such as bronze, copper, stainless steel and aluminum, last for years and are affordable.
