Résumé
Fire tests on a double egress fire door installed in two Cross Laminated Timber (CLT) wall panels were conducted. The purpose of the testing was to identify design consideration for detailing the interface between a 90 min. listed door assembly and a CLT wall with a 2-hr fire resistance.

Résumé
Fire tests on two unprotected 5-ply Cross Laminated Tmber (CLT) floors with pipe penetrations were conducted. The purpose of the testing was to evaluate concepts for detailing metallic and plastic pipe penetration firestops. Although the focus was on flame through performance, some temperature data was collected on insulated and uninsulated metallic pipes.

Résumé
This report provides an overview of major changes occurred in the recent decade to design and construction of the building envelope of wood and wood-hybrid construction. It also covers some new or unique considerations required to improve building envelope performance, due to evolutions of structural systems, architectural design, energy efficiency requirements, or use of new materials. It primarily aims to help practitioners better understand wood-based building envelope systems to improve design and construction practices. The information provided should also be useful to the wood industry to better understand the demands for wood products in the market place. Gaps in research are identified and summarized at the end of this report.

Résumé
The main objective of this study is to evaluate heat delamination characteristics of structural adhesives used for face bonding of cross-laminated timber, when subjecting both sides of CLT specimens to the small-scale flame test as required in the normative Annex A.2 of CSA O177 "Qualification Code for Manufacturers of Structural Glued-Laminated Timber" [3]. While not technically in accordance with the CSA O177 Annex A.2 methodology, this flame exposure allows for a direct comparison to previous work performed on glulam specimens [2]. The long-term objective is to determine which currently-accepted test method allows for a better evaluation of heat delamination characteristics of adhesives used in structural engineered wood products, based on their actual end-use applications (e.g. bending, compression, combined stress, etc.) and their inherent manufacturing characteristics (e.g. cross-plies, etc.)

Résumé
The main objective of this study is to evaluate the heat release rate and fire growth contribution due to heat delamination characteristics of CLT manufactured with four types of adhesives used for face bonding, when exposed to a constant radiant heat flux. The evaluation is performed using the principles of ISO 5660-1 “Reaction-to-fire tests - Heat release, smoke production and mass loss rate – Part 1: Heat release rate (cone calorimeter method)”. The American version of this test method is ASTM E1354 « Standard Test Method for Heat and Visible Smoke Release Rates for Materials and Products Using an Oxygen Consumption Calorimeter ». The long-term objective is to determine which currently accepted test methods allow for the most suitable evaluation of heat delamination characteristics of adhesives used in structural engineered wood products, based on their actual end-use applications (e.g. bending, compression, combined stress, cross-plies, etc.).

Résumé
Depuis quelques années, le revêtement en bois massif a retrouvé ses lettres de noblesse après avoir cédé des parts de marché aux revêtements synthétiques. Ce gain de popularité s’explique notamment par les nombreuses améliorations apportées par les manufacturiers à leur gamme de revêtements, et ce, tant pour ce qui est du moulurage de leurs profilés que de la durabilité de la teinture appliquée en guise de finition, en passant par un rehaussement significatif de la qualité de la fibre utilisée.

Résumé
Nail-Laminated Timber (NLT) and box beam are efficient and economical engineered wood products. Although NLT has been used in North America for more than a century, only in recent years it has gained renewed interests as they have been seen as the most economical panel products used in mass timber buildings. Box beams, on the other hand, are lightweight and generally possess higher strength and stiffness than comparable-sized solid timber and are more efficient than solid timber for large spans and loads. In this report, existing design provisions and their limitations for the design and construction of NLT and box beam in Canadian standards are reviewed. For NLT, there is a general lack of information related to manufacturing, design and construction to ensure consistent manufacturing and installation practices. Therefore, it is difficult to research and document with confidence the full range of performance that can be achieved with NLT. It is therefore recommended that a North American product standard and design information on structural performance, floor vibration, fire resistance, acoustic performance, and construction risk mitigation measures (e.g. moisture and fire) be developed. In CSA O86, design methods are limited to box beams with flanges and webs bonded with glue. As the flanges and webs of a box beam can be assembled by either glue or mechanical fasteners, it is recommended that design provisions for box beam with mechanical joints be also developed. With the information in Eurocode 5 and relevant supporting research papers, it is ready to be implemented.

Résumé
A total of 48 peeler blocks and 256 mini-billets were sampled from mills to investigate the effects of yard storage time, and artificial yard drying and sprinkling on residual moisture contents (MCs) and veneer quality. MC in fresh and stored log inventories varied greatly across mills according to geographic location of their wood supply zones, bark damage and loss, and storage time and conditions. The main findings were as follows: 1. DF logs supplied by three BC mills from the Cariboo, Thompson Okanagan, or Kootenay regions were highly variable in wood MC. 2. Winter-cut DF logs with high sapwood MC stored had good bark retention and high moisture retention over 6 and 9 winter-spring months. No effects on veneer peeling roughness from longer-term winter storage up to 9 months. 3. Summer-cut logs had little or no residual bark, or the bark slipped off very easily during debarking. Exposed, bark-free summer-cut logs can dry and crack on edges and ends very quickly, within a few weeks. 4. A marked decline in veneer quality with piling time in Summer for spruce and DF, suggesting an optimum window of processing of such exposed logs of about two weeks. Veneer quality and recovery suffered markedly once the logs had fully air dried mainly because of edge splits creating natural fragmentation of the ribbon. 5. Mills receiving dry-zone logs with much lower MC have a very limited storage window, especially over winter. As little as 2-3 weeks if bark is damaged or missing. 6. Veneer quality could not be definitively tied to log residual MC. Under the controlled laboratory conditions used here it was observed that peeling quality could still be good at low sapwood MC (35-40%) and or very high (MC>100%). Whether this is still the case in mill production is unknown. 7. Logs must never be allowed to fall below FSP and develop edge-checks or deep end checks. 8. Wax emulsion end sealants were effective at hampering drying and end checking on high MC logs, but not effective on low MC logs. 9. Sprinkling retained log freshness and peel quality in high MC DF for several months and prevented log drying and end splitting as well as inner log staining. Ends absorbed considerable extra moisture. Some variability in peel quality was noted. 10. The prototype EM1000 Ground Penetrating Radar could only be reliably used in log edge mode in DF. The unit would also require re-calibration for the very high sapwood MC in spruce and wet-zone DF logs.
