Bautex Wall System Achieves Four-Hour Fire Rating

Bautex Systems, LLC, a man­u­fac­tur­er of composite insu­lat­ing concrete forms (ICF), has completed testing that further demon­strates the fire resis­tance prop­er­ties of the Bautex™ Wall System. Based on these results, the Bautex Wall System can be specified for struc­tur­al and non-struc­tur­al walls on projects that require fire endurance ratings as high as four hours.

Testing of the Bautex Wall System was conducted by Intertek at their fire lab­o­ra­to­ry in Elmendorf, Texas, in accor­dance with the ASTM® E119 standard. This test measures the trans­mis­sion of heat and hot gases through a test wall, and the continued load carrying ability of the wall when exposed to intense heat, similar to con­di­tions that exist in a structure fire. The Bautex wall specimen was not finished with pro­tec­tive coatings on either side of the wall to demon­strate the fire resis­tance prop­er­ties of the base wall system.

During the test, the Bautex test wall was subjected to tem­per­a­tures reaching 2,000° F, but at no time did the tem­per­a­ture of the exterior wall surface increase more than 15° F. After four hours of heat exposure, the Bautex test wall was removed from the furnace and imme­di­ate­ly subjected to a stream of water from a fire hose for five minutes in order to test the continued integrity of the wall during a fire event. The test wall exhibited no change in struc­tur­al integrity or load carrying ability at any point during the test. 

While most projects do not require a four-hour fire endurance rating for exterior or interior walls, the Bautex Wall System provides this added benefit to every project that specifies Bautex with no addi­tion­al work or expense.

These results demon­strate the dura­bil­i­ty and safety benefits of building with the Bautex Wall System. For more infor­ma­tion on the Bautex Wall System and these fire safety test protocols and results, please download the full test report at bau​texsys​tems​.com.
