Weatherstripping Against Infiltration
Weatherstripping is designed to reduce air leakage around parts of the house that must move relative to one another, like doors and windows. Weatherstripping is easy to install and may be one of the most cost-effective home improvements. Besides improving the efficiency of your heating and cooling systems, weatherstripping keeps out dirt, dust, noise and moisture, and can make the home less drafty. Locating places that need weatherstripping is simple; just feel for drafts around them on a windy day, or turn on a whole-house fan with the doors and windows closed. It will pull air in through cracks, allowing you to identify them. Check all doors and windows, even ones that lead to enclosed but unheated areas like the garage, porch, basement or attic.
