ANSI/APA PRG 320-2011 Standard for Performance-Rated Cross-Laminated Timber, a new standard for cross-laminated timber (CLT), was approved for publication last month by by the American National Standards Institute (ANSI).  is a prefabricated solid engineered wood panel made from at least three layers of solid-sawn lumber or structural composite lumber (SCL) that are stacked cross-wise and bonded together with structural adhesives to form a solid, rectangular-shaped panel that is intended for construction applications, including roofs, floors and walls in residential and non-residential buildings. Orthogonally bonding the layers increases the structural and dimensional stability of the product as a slab or wall.
