Standard for Thermal Insulation – Bead-Applied Two Component Polyurethane Air Sealant Foam, Part 1: Material Specification

1.1 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.

1.2 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.

1.3 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.

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

1.5 Applications and requirements for the applications are included in the CAN/ULC-S710.2 Installation Standard.

1.6 This document does not purport to address all the health and 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.
