“This Standard specifies the requirements and test methods for thermal insulating bead – applied two-component polyurethane foam used as an insulating air sealant for both building and non-building applications. This Standard covers bead-applied two-component polyurethane air sealant foam whether applied on a building site or in a prefabrication (manufacturing) process. This two-component polyurethane air sealant foam is factory pre-packaged.

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

The test methods used to determine the material properties provide a means of comparing different polyurethane air sealant foams. They are intended for use in specifications, product evaluations and quality control.

Bead-applied two component polyurethane air sealant foam shall be installed in accordance with the manufacturer?s instructions and CAN/ULC-S711.2.

Applications and requirements for the applications are included in the CAN/ULC-S711.2 Installation Standard.”
