Architects and construction product specifiers have a new choice for building wall systems that meet the most stringent fire-resistance standards in the United States and Canada. Bautex Systems today announced that the Bautex Wall System is now a part of the QAI Product Listing Program in its Concrete Forms category. Its listing, #B1075-1, covers United States and Canadian standards for the "4-hour Load Bearing Fire-Resistance-Rated Wall Assembly" as confirmed by the ASTM E119 test program.
As building codes evolve to require more energy efficient building envelopes, builders and architects need safer building materials such as Bautex Block that improve a wall’s fire-resistance, because some insulated wall systems and materials may be hazardous under extreme heat or flame.
A third-party testing, inspection and certification organization, QAI Laboratories, confirms that tests performed on the Bautex Wall System were conducted properly. They also periodically conduct factory quality assurance inspections to demonstrate that Bautex products continue to be manufactured to the same standards as the products tested under the QAI listing.
Bautex Systems’ President Paul Brown notes that the QAI listing makes it easy for architects to document how they are achieving the fire rating required on a specific project, and to manage the approval process with local inspectors and code officials. “We’re proud to achieve the QAI listing so that our customers can have confidence in the tests performed on the Bautex Block and wall assembly,” he says. “Architects and contractors now have a new wall system option that delivers the insulation and energy performance required by the building codes while also providing significant fire-resistance capabilities at the same time.”
Test walls built with Bautex Block have passed fire-resistance tests according to the following standards:
ASTM E119 “Standard Test Methods for Fire Tests of Building Construction and Materials,” including an applied load of 105,000 pounds*;
UL 263 “Fire Tests of Building Construction and Materials;”
NFPA 251 “Standard Methods of Fire Tests of Building Construction and Materials;” and
CAN/ULC S101 “Fire Endurance Tests of Building Construction and Materials.”
