1.1 This practice covers the installation of high-pressure spray polyurethane foam (SPF) as an insulation for building enclosure assemblies including: walls, ceilings, attics, floors, and crawl spaces. This practice does not apply to SPF used strictly as a component for an air barrier system or SPF used in roofing applications. 1.2 Building design criteria and selection of SPF are beyond the scope of this practice. 1.3 The use of SPF insulation covered by this practice is typically regulated by building codes or other agencies that address fire performance. Where required, the fire performance of the material shall be addressed through standard fire test methods established by the appropriate governing documents. 1.4 Units--The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
There has long been a need for an application guide.
