Types of Spray Polyurethane Foam (SPF) Insulation and How It's Applied

SPF insulation can be categorized into two types of products:

  • Two-component open-cell foam (ocSPF)
  • Two-component closed-cell foam (ccSPF)

Spray polyurethane foam insulation is applied using two main delivery systems: low pressure spray foam kits/systems and high pressure systems using large drums for open or closed-cell foam.

Spray polyurethane foam kits, refill tanks: For mid-size projects, there are low pressure (typically less than 250 psi or pounds per square inch) two-component kits. These two-component kits can be used to insulate and seal small to mid-size areas around the home, such as attics, crawl spaces, and rim joists. These kits are primarily used by weatherization professionals and spray polyurethane foam contractors. These products require the use of specialized personal protective equipment (for example, high pressure foam is installed with a respirator as noted below).

SPF high pressure systems: Two-component, high pressure systems (typically 800-1600 psi) use 55-gallon drums and are more often used when insulating larger areas on new construction or major renovations on walls and roofs. These products are intended for professional use. These products require special training and the use of specialized personal protective equipment (PPE), including respirators.

For a typical high pressure SPF application, a spray rig (truck) which houses the SPF ingredients, air supply and other items is parked near the home or building to be sprayed. Hoses (up to about 300 ft. in length) are carried to the application area and installers wearing proper protective equipment spray the foam.
