[CCMC evaluation requirements] CAN/ULC-S711.1:2019

This document provides a summary of the minimum requirements imposed by the Canadian Construction Materials Centre (CCMC) for all evaluations based on the below criteria document. Additional requirements may be imposed by the CCMC when necessary for a particular evaluation, and are detailed in the individual evaluation.

Criteria document


These evaluations apply to bead-applied, 2-component polyurethane foam, intended for use as an air sealant for both building and non-building applications. This two-component polyurethane air sealant is prepackaged at the factory. The continuous-use temperature is within the range of –60°C to +110°C.

The standard referenced below covers bead-applied, 2-component polyurethane air sealant foam, whether it is applied on a building site or in a prefabrication (manufacturing) process. This standard includes test methods to determine the material properties and provides a means of comparing different polyurethane air sealant foams. These tests are intended for use in specifications, product evaluations and quality control.


The standard does not address the requirements for this material to be used as a thermal insulation or as fire blocking material.

Per the standard, the durability of the foam is assessed as the continuity component in an air barrier system between:

  • the principal plane of air tightness (that is, polyethylene sheet or other proprietary products specified as the designated air barrier system); and
  • the window or door (that is, wood, vinyl, aluminum, etc.).

Per the standard two-components bead-applied air sealant polyurethane foams are closed cell materials which are installed to a maximum bead cross section of 100 mm.

Material requirements

The evaluation holder must demonstrate that the product meets the following requirements (additional requirements may be imposed by the CCMC when necessary, and are detailed in the individual evaluation):

  • Maximum bead width of 100 mm;
  • Net mass per container;
  • Lot number;
  • "For sealant use only;"
  • “use before” date; and
  • "CAN/ULC-S711.1"
