AtTEK – Fire Protection for Attic Applications

The AtTEK® – Fire Protection for Attic Applications Technical Data Sheet provides detailed product and performance information for BarrierTEK’s AtTEK® fire-protectant treatment used in wood-frame attic assemblies. The document is intended for designers, builders, specifiers, and code officials requiring concise technical data to support product evaluation and specification.

The TDS outlines key product attributes, application parameters, and performance characteristics relevant to attic framing components, including treatment coverage, compatibility with wood products, and applicable fire performance considerations. It serves as a quick-reference resource for understanding how AtTEK® is used to enhance fire protection in concealed roof spaces.

Developed as a technical reference, this data sheet supports accurate specification and informed use of AtTEK® in attic applications, helping project teams integrate fire-protectant-treated wood into wood-frame buildings with clarity and confidence.

Fire Safety Challenges of Tall Wood Buildings

Acknowledging the growing importance of designing sustainable buildings and addressing overpopulation concerns, the development of engineered wood products has introduced the possibility of constructing high-rise timber structures that can improve both these conditions. However, as a combustible material, one of the biggest barriers to construction of tall timber buildings is the potential fire risk resulting from the combustible structure. In November 2012, the Fire Protection Research Foundation commissioned the Fire Safety Challenges of Tall Wood Buildings study to address this concern. Phase I of this two-phase study seeks to collect the available knowledge of fire safety in timber structures and identify gaps in knowledge that would further the understanding of fire performance of tall timber buildings. Results of the study, including a summary of timber construction and fire dynamics, is presented herein.

Shear Testing of Cross-Laminated Beams

This testing program was carried out by the Advanced Building Systems (ABS) Department of FPInnovations in response to a request made by Mrs. Julie Frappier of Nordic Engineered Wood and Mr. Étienne Lalonde of Canadian Wood Council (CWC) for the evaluation of the shear stress resistance of one hundred fifty two (152) cross-laminated timber (CLT) beams. All specimens were manufactured by Nordic Engineered Wood and delivered to FPInnovations’ testing facilities in Québec City. The main objective of this study was to evaluate the in-plane shear stress of CLT depending of its orientation and the number of plies. Specific Gravity and Moisture Content measurements were also determined for each specimen.

Advanced Wood Construction Action Plan

As part of Sustainable Growth: Ontario’s Forest Sector Strategy, the Government of Ontario committed to increasing the use of wood in construction to grow and diversify the market for Ontario’s wood products. This commitment will drive economic prosperity in the province, help to bolster the supply of available housing and support workforce development, all while helping to mitigate climate change stemming from buildings sector emissions.

Arbora – An Exposed Wood Structure in A Major Residential Project

Montreal’s Griffintown district is home to a world record-breaking building: Arbora is the world’s largest residential complex made of solid engineered wood. It boasts three 8-storey buildings, each 25 m high, for a total of 55,515 m2 and 434 housing units. Records can be broken, but the unmatched aesthetic quality of Arbora’s exposed wood beams and columns will endure. Sotramont has assembled a team of skilled professionals to complete this project, the first of its kind in Canada.

IBS5 – Thermal Performance of Light-Frame Assemblies

“A man’s home is his castle” is an old familiar phrase, but if truth be told, the castles of old were cold and draughty. Today’s homes are now havens of comfort with efficient central heating systems and well insulated building envelopes. We count on the walls and roofs of our houses to keep the heat in during the winter months and the heat out during the sweltering days of summer. Today’s home buyers demand energy efficient houses with high insulation values. “Lowering energy use” has become the goal as the cost and environmental implications of energy use are considered. Insulation levels are now being required by many code authorities. Stricter thermal requirements mean that designers must understand the impact of the materials and assemblies used on thermal performance. Because of its long history of use, wood-frame construction has well established insulating properties and record of performance. The effect of other construction systems on insulation properties is not widely known or understood. This publication will examine current knowledge of the thermal performance of wood and other framing techniques. This information will assist designers and builders to select construction techniques that provide the best thermal performance.

IBS3 – Fire Resistance and Sound Transmission

Fire is an ever-present danger for building occupants. Research and experience confirm that fire safety in a house or apartment has little to do with the combustibility of the structural materials used in its construction. In fact, the occupants’ safety is far more dependent on their own awareness of fire hazards (open flames, etc.), the contents of their home (furniture, etc.), and the fire protection measures designed into the building. Minimization of sound transmission in single- and multi-family residential buildings is also an important factor to ensure occupant comfort, and is closely related to fire-resistant construction. The intent of this brochure is to demonstrate how wood frame buildings meet code requirements by providing examples of wood-based light frame building systems designed to maximize fire safety and minimize sound transmission.

CLT Diaphragm Properties

A testing program related to the evaluation of the mechanical properties of CLT diaphragms used in construction was carried out by the Advanced Building Systems (ABS) Department of FPInnovations in response to a request made by the Client, Nordic Engineered Wood Products. The main objective of this study was to determine the in-plane stiffness and potentially strength properties of CLT panels used in diaphragm applications. The test matrix consisted of three (3) series of two (2) specimens each. The CLT specimens were tested under third-point loading during the program. All specimens were manufactured by Nordic Engineered Wood Products and delivered to FPInnovations’ testing facilities in Québec City. The CLT panels were made of nominal 2×4 Black Spruce lumber (CLT Grade E1 – ANSI PRG 320).

Monotonic Quasi-Static Testing of CLT Connections

This testing program was carried out by the Advanced Building Systems (ABS) Department of FPInnovations in response to a request from Mrs. Julie Frappier from Nordic Engineered Wood for the evaluation of the mechanical properties of three (3) different assemblies for attaching Cross Laminated Timber (CLT) panels. Each of the assemblies consisted of six (6) specimens for a total of eighteen (18) tests. All specimens were manufactured by Nordic Engineered Wood and delivered to FPInnovations’ laboratory in Québec City.

The key objective was to evaluate the mechanical properties pertinent for the design of CLT panel connections exposed to in-plane loading such as diaphragms or shear walls. The evaluation of the ultimate loading capacity (𝐏𝐮𝐥𝐭) and the stiffness (K) of the connections are thus the main focus of this study.
