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-A1-100035-01.3 3 rise buildings using either lightweight wood frame or cross-laminated timber as the structural elements. As a result, full-scale standard exterior wall assembly tests were conducted to CAN/ULC-S134.
The foam insulations examined for use in the full-scale test assemblies were typical of those used in present-day construction. In addition, a non-standard test (Test EXTW-5) was conducted using a reduced scale rain screen wall system.
In addition to the full-scale tests, cone calorimeter tests were conducted to select and characterize the foam insulation, water resistant barrier and FRT plywood materials, as well as the regular gypsum sheathing, used in the full-scale tests. Tests were also conducted with the foam insulations protected using the sheathing materials used in the full-scale tests. The results of the cone calorimeter tests are provided in this report.
