About AITC

The American Institute of Timber Construction (AITC) is the national technical trade association of the structural glued laminated (glulam) timber industry. AITC represents glued laminated timber manufacturers in the U.S., as well as installers, suppliers, sales representatives, engineers, architects, designers and researchers.

AITC Glulam

Since 1952, the American Institute of Timber Construction has had one name and one focus – structural glued laminated timber. Utilizing the professional talent and extensive experience of its membership base, AITC originally developed and sponsored the American National Standard of Structural Glued Laminated Timber, ANSI A190.1.

The recognition of AITC as the authority in the laminated timber industry is the direct result of the collaborative efforts of its members in the development and maintenance of today’s industry design and product standards, the establishment of the benchmark industry quality assurance / inspection / grademark program and laminated timber research.

Glued laminated timber manufactured by qualified licensees of AITC, in conformance with the current edition of ANSI A190.1 Standard, may be identified with the AlTC QUALITY INSPECTED grademark, the SYMBOL of QUALITY in ENGINEERED TIMBER since 1963.
