Generally carbon-containing compounds that have sufficient vapor pressure to be present as a gas or vapor at room temperatures. The EPA specifically defines regulated VOCs in 40 CFR51.100s. In the U.S. closed-cell SPF systems generally contain fluorocarbon blowing agents (HFC, HCFC or CFC) that are not classified as VOCs by the US EPA.

SPFA believes that the path to a healthful, safe, high-quality and performing SPF installation travels through the hands of a knowledgeable, trained, experienced, and ideally PCP-certified professional contractor.
