SES offers building envelope testing services to complement our envelope commissioning services, or as an independent service on any project. Field testing can be an instrumental component of a building envelope commissioning program and provide definitive results for quality installations. It can also be used as a diagnostic tool for troubleshooting. Our field-testing equipment can be quickly mobilized for compliance testing of windows, curtain walls, storefronts, sky lights, doors and air vapor barrier systems (AVB). Testing can either be performed in situ or on component mockups to establish initial quality.
