What is sprayed polyurethane foam insulation?

It’s a mix of insulation and sealant. Sprayed polyurethane foam insulation is a rigid cellular plastic with more than 95 per cent closed cell content, so it acts as insulation, an air barrier, and a vapour barrier.

What are the properties of spray polyurethane foam insulation?

  • It’s continuous, seamless, and has no joints;
  • It can fill cracks and holes;
  • It adheres to wood, metal, concrete, masonry, and almost all plastics;
  • It keeps air out;
  • It has a high insulation value (R-value);
  • It’s durable and long lasting;
  • It’s quick to install;
  • It doesn’t settle;
  • It’s the only thermal insulation tested for VOCs;
  • It can be used as a water barrier

Where can spray polyurethane foam be used?

  • Foundations;
  • Crawl spaces;
  • Walls;
  • Rim joists;
  • Roofs;
  • Ceilings;
  • Interior walls

Why is it important to use a certified and licensed installer?

Certified and licensed installers ensure professional installations that meet Canadian standards and adhere to all safety and building codes. The Canadian Urethane Foam Contractors Association Inc. trains, certifies, and licenses installers through its SPF Quality Assurance Program.

Is spray polyurethane foam recognized in the National Building Code?

Yes. The National Building Code recognizes spray polyurethane foam as a thermal insulation. It also meets the requirements for an air barrier material and an air barrier system, and in some cases, a vapour barrier.

Does spray polyurethane foam off-gas?

Off-gas refers to the release of a chemical in the form of gas. All manufactured materials off-gas to some extent, however medium density spray polyurethane foam that meets the CAN/ULC S705.1 material standard is the only building product that is tested for occupant conditions. The insulation industry has taken it a step further and required that all manufacturers meet a maximum limit of 1/100 of the government’s allowable limit. With these high standards in place, spray polyurethane foam is safe for occupants and the environment.

Does spray polyurethane foam burn?

Spray polyurethane foam is an organic material and all organic materials burn. Medium density spray polyurethane foam contains a fire retardant to minimize the spread of flames in the event of a fire.
