The design of buildings often requires that the assemblies have minimum fire endurance or sound attenuation properties. The Canadian Steel Construction Council and the Steel Framing Alliance have published a compilation document on fire and acoustic ratings titled Guide to Fire & Acoustic Data for Steel Floor and Wall Assemblies.

The Canadian Steel Construction Council has also developed the following Fire Protection Bulletins pertaining to cold-formed steel. Click on the title to download.

• Bulletin #23: Practical Fire Protection in Cold-Formed Steel Framed Buildings
• Bulletin #27: Fire-resistance and Acoustic Ratings for Cold-Formed Steel Framed Floor Assemblies
• Bulletin #28: Floor Assembly No. NRC764-FF22 to FF28

There are also two ULC listings for fire resistance ratings of generic LSF floor assemblies:

• LSF non-combustible floor assembly (BXUVC.I523)
• LSF combustible floor assembly (BXUVC.M511)

In addition to ULC, there are a large number of UL listings for cold-formed steel assemblies. UL has recently ruled that applications of UL listings in Canada can be applied with a Load Restricted Factor of one (i.e. no load reduction). This means that the whole range of UL listings can be more readily used in Canada. For more information, go to www.ul.com and search for BXUV7.GuideInfo in their online certifications directory.
