What is Spray Foam Insulation?

Spray foam insulation is an alternative to traditional building insulation such as fiberglass. It is generally made of two substances (polyurethane and a polyol resin) that mix together as they are sprayed out of a gun. This mixture forms an foam that expands when sprayed. It is normally applied to roof tiles in attics, into wall cavities, or through holes drilled in into a cavity of finished walls.

There are two main types of spray foam insulation: open cell and closed cell.

Open Cell Spray Foam Insulation

Open cell means that the cells that form the spray foam are not completely closed. This type is less expensive, and does provide good insulation and sound reduction. It does not provide a reliable moisture barrier, however and is avoided for outdoor applications.

Closed Cell Spray Foam Insulation

Closed cell foam insulation is made up of denser material whose cells are completely closed and compact. It provides both a good air barrier and water vapour barrier. For this reason it is popular in outdoor and roofing applications. Closed cell spray foam has a high thermal insulation value (R-value), which makes it highly effective for preventing heat transfer.

Benefits of Spray Foam Insulation
  • Saves on energy costs and lowers utility bills.
  • Protects against moisture, which reduces the growth of mold and mildew.
  • Reduces noise through walls and roofs by acting as a sound barrier.
