The Fenestration and Glazing Industry Alliance, an industry group that works on standards and education for windows and skylights.
The Fenestration and Glazing Industry Alliance, or FGIA, is an industry organization that brings together companies in the window, skylight and glazing business. It is involved in standards and education, and its work sits behind many of the performance classes and test methods that appear in window specifications. Homeowners rarely deal with it directly but meet its work in product documents.
We are an independent contractor and use industry information to help you read specifications. We explain terms such as performance class, design pressure and air and water resistance in plain language and help you decide which ones matter for your project. For commercial and multifamily work, we match specifications to the building needs.
