The "CAN ULC-S710.1-2019 Standard for Bead-Applied One Component Polyurethane Air Sealant Foam, Part 1: Material Specification" outlines the requirements and test methods for one component polyurethane foam used as an air sealant in building applications. This standard covers materials that can be applied either on-site or in a prefabrication process.

However, it is important to note that this standard does not address the material's requirements for thermal insulation or fire blocking purposes. The components of the foam are supplied in a pre-packaged, pressurized system.

The requirements outlined in the standard only apply to the use of the foam within a temperature range of -60 ° C to +80 °C. The test methods provided in the standard allow for the comparison of different one component polyurethane air sealant foams, but they are not intended to predict the performance of the end-use product.

The foam is an open-cell material that is installed using a bead size cross-section of up to 25 mm. Furthermore, it is important for users of this standard to consult the appropriate authorities to establish health and safety practices in compliance with relevant regulatory requirements prior to its use.
