This Update discusses how various factors affect the fire resistance of floors in multi-family dwellings. The information is based on results from a major industry/government research project carried out by the National Research Council’s Institute for Research in Construction (IRC).* Full story
This Update examines various fire-stopping techniques that meet the intent of the National Building Code of Canada (NBC) with respect to fire resistance and that do not adversely affect the sound isolation of the wall assembly. The information is derived from the results of an industry-sponsored consortium project led by the National Research Council’s Institute for Research in Construction (IRC).1 Full story
Building owners and designers have been limited in the extent to which they can use glazing in fire-rated separations. This Update presents the results of IRC research on the use of dedicated sprinkler systems to protect glazing in fires and provides guidelines that will ensure effective protection in different situations.

Filling a hollow steel column with concrete increases the column’s load-bearing capacity as well as its fire resistance. Concrete reinforced with steel fibres or bars both offer advantages over plain-concrete filling. This article discusses the fireprotection advantages and other benefits achieved with the various types of concrete filling, with emphasis on steel-fibre technology. Full story
This Update discusses the importance of various factors in achieving the required fire resistance for walls in multi-family dwellings.
