Cavity Wall Insulation 101

Does your home have cavity walls and should they be insulated? Cavity walls are two walls/materials separated by a hollow space (cavity). The materials are often masonry such as brick or concrete block.

Your home may need cavity wall insulation if:

  • Its external walls are unfilled cavity walls
  • Your cavity is at least 50 millimeters wide
  • It is more than a decade old (most newer houses will have insulation already)

But it’s always a good idea to ask a professional! Someone on the Installed Building Products Portland team can assess your home’s walls and determine the right solution.

What Is Cavity Wall Insulation?

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. This is referred to as cavity wall insulation. Cavity walls (in homes and commercial buildings) are often insulated when they are first built—but retrofit installation projects can be completed as well.

Different materials can be used to insulate cavity and external walls, but spray foam and fiberglass are most often used.
