Freres Lumber Co., Lyons, Or., was granted a Canadian patent for its Mass Plywood Panel (MPP), reportedly the only mass timber panel constructed entirely from Structural Composite Lumber (SCL).
The company received the Canadian patent the day after the hard copy of their U.S. patent arrived in the mail. Patents have also been granted in Australia and New Zealand.
Additionally, Freres received fire test results from Southwest Research Institute, verifying that MPP demonstrates the necessary life safety fire protection performance for single- and multi-family, and multi-story structures up to 18 stories high.
“Freres Lumber has spent the last three years researching, developing and testing MPP, and our hard work has come to fruition with the patents being awarded and industry tests verifying the strength, safety and versatility of this product,” said VP Tyler Freres. “The ASTM E119 and E84 tests are rigorous tests that exposed the panels to intensely hot flames. The test results allow designers and developers to use MPP in buildings that require fire resistance ratings.”
