[CCMC evaluation requirements] CAN/ULC-S710.1-11, Class 2

From: National Research Council Canada

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 thermal insulating, bead-applied one-component polyurethane foam. It is intended for use as an insulating air sealant for both building and non-building applications. This one-component polyurethane air sealant is pre-packaged at the factory. The continuous-use temperature is within the range of −60°C to +110°C.

The standards referenced below cover bead-applied one-component polyurethane air sealant foam, whether it is applied on a building site or in a prefabrication (manufacturing) process. These standards include test methods used 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.

Products manufactured in conformance with CAN/ULC-S710.1-11 standard are:

  • classified as Class 1, 2 or 3 in accordance with their flame-spread value;
  • installed in accordance with the manufacturer’s instructions and CAN/ULC-S710.2-11, “Standard for Thermal Insulation – Bead-Applied One Component Polyurethane Air Sealant Foam – Part 2: Installation.”


The durability of the foam is assessed as the continuity component in an air barrier system between: (i) the principal plane of air tightness (i.e., polyethylene sheet or other proprietary products specified as the designated air barrier system, and (ii) the window or door (i.e., wood, vinyl, aluminum).

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):

Additionally, in compliance with the CAN/ULC-S710.1-05, each container/package must be marked with the following information:

  • manufacturer’s name and address;
  • product name and class;
  • tested bead width;
  • net mass per container;
  • lot number;
  • date of manufacture;
  • “use before” date;
  • conformance with CAN/ULC-S710.1-05 or CAN/ULC-S710.1-11; and
  • reference to CAN/ULC-S710.2-05 or CAN/ULC-S710.2-11 for installation.
