1. SCOPE 1.1 This Standard specifies the requirements for the installation of thermal insulating
bead-applied two-component polyurethane foam used as an insulating air sealant (including a
component within an air barrier system) for both building and non-building applications. The
material is installed as air sealant foam in holes, cracks or gaps. 1.2 These are requirements for both the manufacturer and the installer. 1.3 Bead-applied two component polyurethane foam shall not be used when the
continuous service temperature is outside the range of -60 to +110ºC. 1.4 These requirements include the proper selection of the air sealant foam,
installation requirements, limitations for the installation, testing, recommendations for safety and
recommendations for disposal of associated waste material and packaging. 1.5 Installation of two-component polyurethane air sealant foam according to this
Standard may require the use of materials and/or equipment that could be hazardous. This
document does not purport to address all the safety aspects associated with its use. Anyone
using this Standard has the responsibility to consult the appropriate authorities and to establish
appropriate health and safety practices in conjunction with any existing applicable regulatory
requirements prior to its use.
