Finding The Right Insulation For Your Project: Meet More Stringent Energy Codes And Sustainability Requirements

With so many choices of insulation materials, how do designers choose the right product for their project? The complexity of choosing the right insulation has increased with higher energy codes.  Step Codes in BC, proposed Tier Codes in the National Building Code, Net Zero, Passive Haus and other high standards are requiring buildings to use less energy to operate; consequentially, resulting in a significant increase in the amount of insulation required, and a tighter envelope via an air barrier system. 
The new generation of closed cell spray polyurethane foams use HFO blowing agents resulting in an insulation with one of the lowest amounts of embodied carbon.  In addition, closed cell spray polyurethane foam is a versatile product that fulfills more than one function in a building envelope and can lower the overall embodied carbon of an assembly by eliminating the use of additional products to fulfill other functions. Furthermore, as one of the highest R values per inch insulation material, it allows assemblies to achieve the required R values while keeping the assemblies’ thickness as thin as possible compared to other insulation materials. 

This paper outlines the research and testing that was completed with one closed cell spray polyurethane foam (cc SPF) insulation:

a) Being the primary component of air barrier assemblies tested in accordance with the reference standard CAN/ULC S742 in the 2015 National Building Code of Canada
b) As an alternative solution to 6 mil poly as a Radon barrier for code compliance based on methodologies established by the Candian Construction Materials Centre
c) As part of an assembly to meet fire requirements in the code for fire resistance rating in accordance with CAN/ULC S101
d) As part of assemblies that provide flexibility in meeting differing levels of effective R value requirements for Canada
e) Being part of an industry wide Environmental Product Declaration (EPD)

Research and testing completed confirms that cc SPF can be used in a wide range of applications, and more importantly, can fulfill various functions in a building envelope. As a result, walls are considerably thinner with lower embodied carbon.

Although the generic information provided may apply to all closed-cell spray polyurethane foams, the research and testing described in this paper was done on one specific foam from a specific manufacturer. It is important to note that building codes require each individual foam to be tested per the applicable standards. It is the responsibility of the designer to ensure the ccSPF specified for the project meets codes and standards.
