ULC 705.1

This Standard provides the physical property requirements and test methods to determine the material properties for medium density closed cell spray-applied rigid polyurethane foam, used for thermal insulation or for other purposes in building and non-building applications in both site-built construction and prefabrication (manufacturing) facilities.

Standard CAN/ULC-S705.2 includes mandatory requirements for the installation of the material as well as the requirements of contractors and the qualification of installers.

The test methods listed in this Standard are used to determine the values for the physical properties. These physical property values are intended for use in specifications, product evaluations and quality control. They are not intended to predict end-use product performance under all conditions.

This edition includes extensive revision to the Terminology, Requirements and Testing Sections, as well as new requirements on how suppliers identify their installed products.
