Which organization establishes specifications for aluminum siding, including metal qualities?

The organization that establishes specifications for aluminum siding, including the qualities of the metal used, is the Aluminum Siding Association. This organization is focused specifically on the aluminum siding industry, ensuring that standards are set for product quality, safety, performance, and installation practices. By developing these standards, the Aluminum Siding Association helps manufacturers, builders, and homeowners know what to expect regarding durability and performance, thus promoting quality and consistency in aluminum siding products.

The other organizations mentioned focus on different aspects of housing and construction. For instance, the Federal Housing Administration primarily deals with mortgage insurance and housing affordability rather than setting product specifications. The American National Standards Institute plays a broader role in developing standards across various industries but does not specifically address aluminum siding. The National Association of Home Builders works more on advocacy and education for builders and developers, rather than establishing technical specifications for specific materials like aluminum siding.
