Cavity Wall Insulation

Most newer homes in the Washington, DC area (and across the United States) have cavity walls—and insulating them is important. Cavity walls are two walls/materials separated by a hollow space (cavity). The materials are often masonry such as brick or concrete block.

Insulation for Cavity Walls

Insulation can be installed to help reduce heat loss through a cavity wall by filling the empty space with material that helps stop heat transfer. Cavity walls (in homes and commercial buildings) are often insulated when they are first built—but retrofit installation projects can be completed as well. Cavity wall insulation is usually blown into the cavity from the outside of the house.

Your home may need cavity wall insulation if:

  • Its external walls are unfilled cavity walls
  • The cavity is at least 50 millimeters wide
  • It is more than a couple decade old (homes built in the 1970s or earlier are more likely to not be insulated enough)

Keep in mind that it’s always a good idea to ask a professional. Someone on our team can assess your home’s walls and determine the right solution. Different materials can be used to insulate cavity and external walls, but spray foam and fiberglass are most often used.
