The process for applying for a Window Energy Rating
2) Submit application
An independent agent will check the quality management of your manufacturing base and submit your application to the certifying body. There will be a fee for this service. All applicants will be visited by an approved inspector unless the installer is third-party certified through their fabricator. Applicants must satisfy the requirements of this inspection as well as any further periodic inspections to acquire and maintain their WERs.
