Bautex Block Passes Key Building Materials Fire Safety Tests


Bautex Systems, LLC, a man­u­fac­tur­er of energy efficient wall systems for com­mer­cial con­struc­tion, has earned high marks in key fire safety tests for the Bautex Block, a building product made from a specially for­mu­lat­ed insu­lat­ing composite material that utilizes recycled com­po­nents. The Bautex Block is the primary component of the Bautex Wall System – a com­mer­cial concrete wall system that inte­grates strength, dura­bil­i­ty, energy effi­cien­cy and design flex­i­bil­i­ty at a cost that is com­pet­i­tive with tra­di­tion­al building methods.

QAI Lab­o­ra­to­ries conducted the ASTM E84-11, Standard Method of Test for Surface Burning Char­ac­ter­is­tics of Building Materials” test, which measures how quickly flames spread across a building material and the amount of smoke that is developed when the product ignites. During the 10-minute test where the Bautex Blocks were subjected to intense direct flame from gas burners, no flame spread was observed and extremely low smoke levels were detected. This resulted in a flame spread index of 0 and a smoke devel­op­ment index of 20, earning the Bautex Block the highest NFPA Class A and IBC Class A classifications.

At the same time, QAI Lab­o­ra­to­ries also conducted the NFPA 286, Standard Methods of Fire Tests for Eval­u­at­ing Con­tri­bu­tion of Wall and Ceiling Interior Finish to Room Fire Growth” test, which deter­mines how far flames spread and how much heat is generated during a fire in an actual building structure. To simulate typical built con­di­tions, the 15-minute room corner burn test was first conducted with 5÷8” gypsum drywall attached to the inside of the 8 foot by 12 foot room con­struct­ed of Bautex Block. To further prove the fire resis­tance qualities of Bautex Block, a second test was conducted on unfin­ished Bautex Block. In both tests, lab tech­ni­cians observed extremely low heat release and tem­per­a­ture rise, and absolute­ly no flame spread, clearly meeting the NFPA 101 Life Safety Code® for both finished and unfin­ished walls.

We knew the product would perform well in these fire tests, but we were very pleased to see that the Bautex Block far exceeded our expec­ta­tions,” said David Sterne, Vice President of Sales and Business Devel­op­ment for Bautex Systems. The tech­ni­cians at the lab were skeptical at first since 85% of our product is recycled foam plastic, but by the end of our week of testing, the cement-EPS for­mu­la­tion we developed for the Bautex Block proved to be highly effective in resisting the spread of flames and smoke in a simulated structure fire.”

Bautex Systems is committed to providing archi­tects, engineers and building con­trac­tors with all the tools and data necessary to design and build struc­tures that radically improve the built envi­ron­ment. Extensive product testing is just one way that Bautex exceeds the demands of design. Test reports, design tools and many other resources can be found at bau​texsys​tems​.com.
