Summary
A test program was conducted to generate hygrothermal performance data for light-wood-frame exterior walls meeting the R22 effective (RSI 3.85) requirement for buildings up to six storeys in the City of Vancouver. Six types of exterior wall assemblies, with 12 wall panels in total, were tested using a test hut located in the rear yard of FPInnovations’ Vancouver aboratory. This document provides a brief summary of the test and performance of these walls based on the data collected over the 19 months’ period from October 2018 to May 2020

Summary
Related sections in the International Building Code (IBC) were reviewed regarding use of wood components in non-combustible buildings, and light-frame wood buildings or heavy timber buildings greater than 4-storeys in height. The highlights of this review are: a) Fire-retardant-treated (FRT) wood can be used in partitions when the required fire-resistance rating is not more than 2 hours. This includes all types and occupancy groups of Types I and II construction; b) FRT wood can be used in non-bearing exterior walls in Type I, II, III and IV construction; c) Wood components can be used in interior walls for Type III and IV construction; d) Wood components can be used in both interior and exterior walls for Type V construction. When a sprinkler system is installed according to NFPA 13 [1], it is possible to build a light-frame wood building or heavy timber building over 4-storeys according to the following provisions: a) Type IIIA 6-storey light-frame wood buildings using FRT wood for exterior walls for Occupancy group B (Business), H-4, and 5-storey light-frame wood buildings for Occupancy group F-2, H-3, I-1(Institutional), R (Residential), S-2; b) Type IIIB 5-storey light-frame wood buildings using FRT wood for exterior walls for Occupancy group R; c) Type IV (HT) 6-storeys timber buildings for Occupancy group B, F-2, H-4 and S-2; d) Type IV (HT) 5-storeys timber buildings for Occupancy group F-1, H-3, I-1, R, S-1 and U.

Summary
This project evaluates the National Building Codes of Canada (NBCC) clauses relevant to fire performance and performance requirements of non-load-bearing wood-frame in-fill walls in concrete/steel hybrid buildings. Related clauses in NBCC are reviewed regarding the use of wood components and non-load bearing wall systems in non-combustible buildings. The highlights of this review are: § An exterior non-loadbearing wall assembly with combustible components is allowed in non-combustible construction if: a) Building height is not more than 3 storeys or has a sprinkler system throughout ; b) The interior surfaces of the wall assembly are protected by a thermal barrier ; and c) The wall assembly satisfied the testing criteria for CAN/ULC S134 ; § Combustible interior wall finishes, other than foamed plastics, are allowed in non-combustible construction if the thickness is not greater than 25 mm and their flame spread rating (FSR) is not more than 150 ; § Combustible insulation, other than foamed plastics, is allowed in non-combustible construction if the flame-spread rating not more than 25 ; § Combustible insulation with a FSR not less than 25 and not more than 500 is allowed in exterior and interior walls of non-combustible construction if the building is non-sprinklered and not more than 18 m or sprinklered and protected by a thermal barrier ; § There are no obstacles for using wood-frame in-fill wall systems for interior partition walls in hybrid buildings: a) For non-sprinklered buildings not greater than 3 storeys or a floor area not greater than 600 m2 ; b) For sprinklered buildings. § Non-combustible construction allows combustible elements in partition walls in the following instances: a) Solid lumber partitions located in a fire compartment area are permitted in a non-sprinklered floor area not greater than 600 m2 with restrictions ; b) Solid lumber partitions not less than 38 mm thick and partitions that contain wood framing are permitted with restrictions. § Combustible cladding can be used under the following circumstances: a) When a wall assembly with exposing building face is between 10 to 25% tested by CAN/ULC-S134 and complies with Article 3.1.5.5 ; b) When a wall assembly with exposing building face is between 25 to 50%, is sprinklered throughout, installed on a gypsum board sheathing, and has a FSR not more than 25 (with restrictions) ; c) When a wall assembly with exposing building face is between 50 to 100%, cladding can be combustible for group A, B, C, D, E, F. § When a building is required to be of non-combustible construction, combustible elements are limited to the requirements in Subsection 3.1.5 on non-combustible construction ; § When comparing the NBCC with the International Building Code (IBC), the IBC is more in favour of using FRT wood frame in-fill walls with one more storey.

Summary
This report describes a full-scale exterior wall fire test conducted on December 16, 2014 on a Nordic cross-laminated timber (CLT) wall system. The test was conducted in accordance with CAN/ULC-S134-13, Standard Method of Fire Test of Exterior Wall Assemblies. The test was conducted using the exterior wall fire test facility located in the Burn Hall of the NRC Fire Laboratory, Mississippi Mills, Ontario. The CLT wall system was assembled to represent a continuous solid wood wall covered by a water barrier membrane and insulation. The pilot burners were lit prior to the commencement of the test. Gas flow to the burners was manually adjusted to follow the prescribed heat input required by the standard.

Summary
Un programme d’essais a été réalisé en vue de générer des données sur le rendement hygrothermique des murs à ossature légère de bois qui répondent à l’exigence R22 (RSI 3,85) pour les bâtiments d'au plus six étages à Vancouver. Six types d’assemblage de mur extérieur, avec un total de 12 murs extérieurs, ont été mis à l’essai à l’aide d’une hutte d’essai située dans la cour arrière du laboratoire de FPInnovations à Vancouver. Le présent document présente un court résumé de l’essai et du rendement de ces murs en se basant sur les données recueillies sur une période de 19 mois, soit d’octobre 2018 à mai 2020 (Wang 2021).

Summary
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.

Summary
This new study aims to generate hygrothermal, particularly moisture-related performance data for light wood-frame walls meeting the R22 effective (RSI 3.85) requirement for buildings up to six storeys in the City of Vancouver. The overarching goal is to identify and develop durable exterior wood-frame walls to assist in the design and construction of energy efficient buildings across the country. Twelve test wall panels in six types of wall assemblies are assessed in this study. The wall panels, each measuring 4 ft. (1200 mm) wide and 8 ft. (2400 mm) tall, form portions of the exterior walls of a test hut located in the rear yard of FPInnovations’ Vancouver laboratory. This report, second in a series on this study, documents the performance of these wall assemblies based on the data collected over 19 months’ period from October 2018 to May 2020, covering two winter seasons and one summer.
