Freres Mass Ply Design & Construction Guide

The Freres Mass Ply Design & Construction Guide is a comprehensive technical resource for Mass Plywood Panels (MPP), a patented veneer-based engineered wood product developed as an alternative to Cross-Laminated Timber. The guide covers Mass Ply products including panels, beams, and columns, manufactured from density-graded Douglas Fir veneers and certified under ANSI/APA PRG-320 and ASTM D5456 standards. Mass Ply products offer advantages over traditional CLT including better dimensional stability, the ability to use smaller diameter trees, and superior structural performance per volume of material used.
