The Window & Door Manufacturers Association is a trade association representing the leading producers of sash, frames, window units, skylights, flush doors, stile and rail doors and sliding patio door units for the domestic and export markets. Members sell to distributors, dealers, builders, remodelers, architects, contractors and other specifiers in residential, commercial and institutional markets. WDMA members manufacture high performance products designed and built to performance-based standards.
 There are three basic types of WDMA membership: Manufacturer members, Supplier members and Professional members. Manufacturer membership is open to any company that manufactures windows, doors or skylights within North America. Supplier membership is open to any company that provides a product, component, material or service that is used in manufacturing windows, doors or skylights (Supplier membership is not restricted to North America). If a company should qualify under both the Manufacturer and Supplier categories, they will be considered a Manufacturer member. Professional membership is available to those individuals who are not directly involved in the industry through either of the other two categories (i.e., architects, engineers, builders, contractors, specifiers, etc), but do have an interest in staying current with industry developments.
