Fire Testing

Sprinkler Loading

Question: 

Does the NFPA sprinkler standard address sprinkler loading? If so, how and where do I buy it? What other information do you have on sprinkler loading? How do other truss companies price jobs for sprinkler loading the plans do not include a sprinkler layout or even say what size/type of sprinkler system will be used?

Duct And Light Penetrations Of Fire Rated Assemblies

Question: 

In a small scale multi-family residential project, I'd like to use a wood truss floor-ceiling assembly to achieve a one hour separation between units. I'd like to directly attach the drywall to the underside of the trusses & use the truss space for ducts & lighting (the floor above will be lightweight concrete on plywood sub-floor). UL assemblies do not seem to address the duct/light penetrations in such an assembly. Can I achieve a one-hour rating in such an assembly and how are penetrations addressed? Can the ducts in the truss space serve both units above and below?

Information On Truss Fire Issues

Question: 

I am trying to develop a guideline for my firefighters regarding initial fire attack in buildings with light-weight trusses. My concern is truss failure, especially when exposed to fire. Is there any information on failure time related to flame impingement? Any information about truss failure – especially in a fire condition would be helpful.

Single Membrane Floor Protection - Educational Program

This presentation provides information on the use of gypsum wallboard in single membrane floor protection.

Single Membrane Floor Protection Requirements of 2012 IRC Section R501.3 & 2015 IRC Section R302.13

This Research Report aims to enhance fire performance and fire safety characteristics through the application of a gypsum wallboard membrane.

Advocating with Evidence

A CM in Pennsylvania is taking a proactive approach to dealing with exception four of IRC provision R501.3.

Preserving & Growing Market Share

  • By conducting its own ASTM E119 floor assembly fire testing, SBCA has the data it needs to effectively fight the controversial IRC Section R501.3 code provision and help preserve CMs’ market share.
  • SBCA has drafted template best practice language CMs should consider using in their TDDs, customer contracts and submittal documents to counter the efforts of the lumber industry to shift liability onto end users.
  • Through Framing the American Dream and WorkForce Development efforts, SBCA is actively engaged in helping CMs successfully navigate today’s labor challenges and grow their businesses.
