Fenestration. We do one thing and we do it well. FMA brings together manufacturers in the window and door space with suppliers to the industry for collaborative brainstorming on engineering challenges, environmental safety, modern technology, design advances, and emerging trends to provide solutions that are practical, safe, and highly regarded among professionals. Our advocacy team works closely with state building code officials to ensure the industry is not only well represented, but used as a valuable resource in shaping future regulation.
