One of the tasks in the project, Wood and Wood-Hybrid Midrise Buildings, was to
develop further information and data for use in developing generic exterior wall systems
for use in mid-rise buildings using either lightweight wood frame or cross-laminated
timber as the structural elements. This report describes a standard full-scale exterior wall
fire test conducted on May 22, 2012 on a simulated cross-laminated timber (CLT) wall
assembly with an attached insulated lightweight wood frame assembly protected using
gypsum sheathing. The test was conducted in accordance with CAN/ULC-S134 .
