Insulation Does Not Stop Airflow

One of the fundamental facts about insulation is what the material actually does. Because insulation is often added to parts of a home where air leakage can occur, it’s logical to assume that insulation blocks these leaks. However, this is not the case. Insulation is designed to slow heat transfer, not to block air. Think of insulation as having a thermos effect on your home. Ideally, your insulation should be keeping the hot things hot and the cool things cool. In the winter, when you’re running your furnace, insulation reduces the rate at which heat radiates out through the walls and other surfaces. In the summer, when your AC is on, insulation keeps out the sun’s heat.


Ensure Proper Air Sealing Before Adding Insulation

There are important preparation methods before adding insulation. Air leakage can occur in many different parts of your home, but if you’re planning on upgrading your insulation, you’ll want to focus on areas where insulation will be added:

  • Walls – In an existing house, air sealing inside the walls isn’t practical. But you can take care of leaks around the walls. Use an all-purpose caulk to seal electrical outlets and light switches. Outdoors, seal the gap between the siding and foundation, corner joints of your siding, and any other gaps in your exterior.
  • Attic – Attics contain a lot of potential leak sites. Run a bead of caulk under and behind knee walls and around the cavities inside dropped soffits. Add flashing around the furnace flue and seal the space between the flue and flashing with silicone caulk rated for high temperatures.
  • Basement – Seal under the sill plate which is between the sill plate and the foundation.


You Don’t Always Need a Vapor Barrier

A vapor barrier is a layer of material designed to control the amount of water vapor that seeps into an enclosed area such as a crawl space or attic. These barriers are commonly made of plastic sheeting or rubber but can be made of a wide variety of material depending on the local climate and type of insulation used. Vapor barriers are usually added during construction in humid climates or ones that see temperature extremes. Homes in dry and mild climates are often built without these layers because building materials, such as painted drywall, are enough to control moisture in these climates.
