NGA and the Fenestration & Glazing Industry Alliance (FGIA) announced the joint publication of a new technical resource, Compatibility Testing of Insulating Glass PIB Primary Sealant with Respect to Glazing Materials. The document discusses methods of compatibility testing of glazing components with respect to Polyisobutylene (PIB) primary sealant in an IGU. It recommends the use of the ift Rosenheim test method, outlines the effects of incompatible glazing materials and addresses other factors that may affect compatibility.
“It is easy for people to assume that, because a process is considered industry standard, that a standard actually exists for testing a product; that isn’t always the case,” explains Robert Carlson, Tristar Glass Products and NGA’s task group co-chair. “The research and collaboration behind this technical resource has been ongoing over the past eight years. We’re excited to be publishing a document long-needed within the industry to formalize our approach to compatibility testing.”
