Spray Polyurethane Foam (SPF) Home
Spray polyurethane foam (SPF) is an effective insulation and air sealant material; however, exposures to its key ingredient, isocyanates such as "MDI," and other SPF chemicals that may be found in vapors, aerosols, dust or on surfaces during and for a period of time after installation may cause adverse health effects such as asthma. Therefore, steps to control exposures and safety tips should be followed.
Information on these Web pages is aimed at helping to ensure the safety of SPF applicators and building occupants where SPF is installed. It is also aimed at providing safety and scientific information to professionals in business, non-governmental organizations, academic institutions, and regulatory agencies.
The Symposium on Developing Consensus Standards for Measuring Chemical Emissions from Spray Polyurethane Foam (SPF) Insulation will take place in Anaheim, CA on April 30 – May 1, 2015.
Read EPA's draft Ventilation Guidance for Spray Polyurethane Foam Application for basic ventilation principles and strategies to help protect workers and building occupants.
Certification and Training
The SPFA Professional Certification Program is for those active in both roofing and insulation installations of spray foam and encourages safety in the installation of spray foam. SPF system houses also offer classroom and hands-on instruction on the safe use of SPF. Also, receive free basic online training on CPI’s website.
