Make Your Home More Energy Efficient

Air sealing is an effective way to make your home more comfortable and energy efficient.  

Winter in Wisconsin—that means snow, ice and colder temperatures. Air sealing around windows and doors is an effective way to keep heated air inside your home this winter. These strategies can help:  

  • Window film is an inexpensive way to help reduce drafts and condensation in winter. It is easy to apply and can even be used over mini blinds.  
  • Caulk to seal air leaks around windows. Caulking compounds come in a variety of strengths and prices. Most are available in disposable cartridges that fit in a caulking gun. Additionally, some caulk comes in squeeze tubes, ropes or aerosol cans. Caulk should be applied during dry weather when the temperature is at least 45 degrees Fahrenheit.  
  • Weatherstripping works well to seal air leaks around movable components like doors. It is available in many different materials, so it's important to read the packaging and choose the right type for your project. Proper application is key. Be sure your weatherstripping meets tightly in the corners. Apply one continuous strip along each side. Weatherstrip the entire door jamb. 
  • Another good place to consider air sealing is the attic. Air sealing and insulation go hand in hand. Air sealing should be done first to stop warm air from rising into the attic. Consider hiring a professional to install a full air-sealing package.
