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 The requirements in this Standard only apply to the use of bead-applied two component polyurethane
foam when the continuous service temperature is in the range of -60 to +110 °C.
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.
