Qualified installers

This is a site-manufactured product, whereby SES Foam LLC. requires that only specific, qualified installers be authorized to install their proprietary spray-polyurethane insulation in buildings. In accordance with the SES Foam LLC. site quality assurance program (SQAP), Caliber has been commissioned to license the specified installers and issue the requisite Caliber identification card to them. All specified installers must have a Caliber identification card.

Third-party field auditing of qualified installers

As part of their SQAP, SES Foam LLC also stipulates that site-audit inspections be conducted by site inspectors licensed by Caliber. Upon completion of the site audit, Caliber will report the product’s conformity results and any corrective action required, if necessary, to SES Foam LLC.

Building officials who would like site-audit  inspections to be conducted on specific building sites can contact Caliber at:

Administrative information


This evaluation is issued by the Canadian Construction Materials Centre (CCMC), part of the Construction Research Centre at the National Research Council of Canada (NRC). The evaluation must be read in the context of the entire CCMC Registry of Product Assessments and the legislated applicable building code in effect.

The CCMC was established in 1988 on behalf of the applicable regulator (i.e., the provinces and territories) to ensure—through assessment—conformity of alternative and acceptable solutions to regional building codes as determined by the local authority having jurisdiction (AHJ) as part of the issuance of a building permit.

It is the responsibility of the local AHJs, design professionals, and specifiers to confirm that the evaluation is current and has not been withdrawn or superseded by a later issue. Please refer to the website or contact:
