In April 2022 The IAA published on its website and on social media that Permarock Products' membership had been terminated as they are no longer an IAA approved System Designer. For clarification, the decision to end its membership was a decision wholly of Permarock Products' own choice. The termination of membership in no way suggests that Permarock Products did not meet the standards required by The IAA, or that The IAA had any other concerns regarding the quality of Permarock's products, services or operations.
