Installing Low-Pressure Spray Polyurethane Foam (SPF) Insulation

As part of the polyurethanes industry’s ongoing commitment to product stewardship, the Center for the Polyurethanes Industry (CPI) prepared the video below called “Working Safely with Low-Pressure Spray Polyurethane Foam Insulation,” for professionals who apply low-pressure spray polyurethane foam. This video provides general guidance for professionals on how to apply low-pressure spray polyurethane foam. It is intended as a supplement to other job safety information already available, such as specialized training, Safety Data Sheets (SDS), product label information and other materials.

Low-pressure SPF and Energy Efficiency

Government incentives, along with public interest, have put a spotlight on reducing energy usage. It also has helped fuel growth in the “green jobs” segment of the economy. As the home weatherization and green building industries respond to growing demand, SPF insulation continues to gain popularity for its ease of use and ability to help reduce energy needs and improve indoor comfort. In addition, reduced energy use to heat and cool a home helps reduce greenhouse gas emissions.

There are usually holes, gaps, and cracks found around the doors, window frames, pipes and plumbing lines, electrical outlets, attics and basements and many other areas in a home or building. Often, older homes and buildings have outdated or inefficient insulation systems. This allows outside air to leak into the building. When added up, these gaps and cracks can be equivalent to having a window or door open. In older homes that have not been weatherized, it is estimated that 20-50% of heating and cooling bills are wasted on air leakage (source: Michigan Energy Options).

The U.S. Department of Energy’s “Energy Savers: Tips on Saving Energy & Money at Home” website provides information about the different types of SPF insulation that you may consider using as a weatherization professional – and offers some important safe use and handling guidance.
