Engineering & Testing

SBCA has recently published an updated and expanded research report on the fire resistance ratings of various truss assemblies. The revised document covers more assembly designs and options than the previous version.

A letter form the AWC is being shared to make it clear to the marketplace the extent to which politics, not science-based facts, resulted in R501.3 being drafted and adopted into the 2012 IRC, and the lengths to which one of its original authors, namely AWC, will go to preserve it.

This article contains public email correspondence from  Mr. Steve Orlowski of NAHB and is being shared to make it clear to the marketplace the extent to which politics, not science-based facts, resulted in R501.3 being drafted and adopted into the ICC's 2012 IRC.

The top 10 headlines for Energy Efficiency & Building Science News in the Q3 of 2015 highlighted a number of innovative new products and designs.

The following article provides a summary of what was learned through the ASTM E119 floor assembly fire testing SBCA conducted in March 2016.

This article summarizes correspondence between APA and SBCA, and how the code's treatment of OSB creates an artificial structural performance expectation, and therefore a competitive advantage, against competing products.

 This article summarizes the mission and goals of the SBCA-SBCRI Investigative Report Series reports.

AWC and NAHB created a competitive advantage for 2X10s though the building code development process.

This article provides information on fire performance equivalency issues and how it pertains to 2x10s and other floor assemblies subjected to ASTM E119 fire testing.
