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.

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.
