FPInnovations is involved in a large research project regarding CLT construction. One objective
of this research is the creation of a design methodology for calculating the fire-resistance of CLT
assemblies/construction. This methodology will foster the design of fire-safe buildings of wood
or hybrid construction. In order to establish such calculation methods, a series of experimental
tests has been undertaken. A total of eight full-scale CLT fire resistance tests have been
conducted at the NRC fire laboratory where the panels were subject to the standard ULC S101
[1] fire exposure. The series consisted of three wall and five floor tests. Each test was unique
using panels with a different number of plies and varying thicknesses. Some of the assemblies
were protected using CGC Sheetrock® FireCode® Core Type X gypsum board while others
were left unprotected.
