Pollution• In the United States,

• Due to the high energy usage, they are a major source of the pollution that causes urban air quality problems and pollutants that contribute to climate change.
Weatherization Procedures
• Sealing gaps, racks and holes using caulk, foam sealant, weather-stripping, and window film.
• Sealing air ducts, which can account for 20% of heat loss, using fiber-reinforced mastic.
• Protecting pipes from corrosion and freezing.
• Providing proper ventilation to unconditioned spaces to protect a building from the effects of condensation.
