The Bautex Block has proven its strength, durability, insulating properties and fire and storm resistance through rigorous testing performed by ICC accredited third-party laboratories.

Lab Tested Performance.

Fire Safety

The Bautex Wall System can be specified for projects that require fire endurance ratings as high as four hours, and is a listed fire-rated assembly with QAI Laboratories under both U.S. and Canadian fire safe standards. With Bautex Block, builders can avoid issues related to fire code requirements since there is no exposed foam plastic insulation.

  • Bare Bautex Wall: Meets NFPA 101 Life Safety Code®
  • Finished with 5/8” gypsum drywall: Meets NFPA 101 Life Safety Code®

Storm Safety

Bautex Walls assembled with simple masonry veneer meet Federal Emergency Management Agency FEMA 320 and FEMA 361 guidelines for residential and community safe rooms in storm zones with potential wind speeds up to 250 miles per hour (Zone IV). By meeting the FEMA requirements for wind debris penetration, the Bautex Wall System provides tremendous levels of protection in extreme weather events, and meets insurance requirements for buildings located in hurricane and tornado prone areas of the United States.

Energy Efficiency

The Bautex Wall System combines R-14 continuous insulation, thermal mass, and an airtight envelope to create an extremely energy efficient wall system that provides optimal energy efficiency for many climate zones.

  • R-value per inch: 1.84
  • Whole wall R-value (with concrete): R-14

Sound Transmission

The Bautex Wall System received high Sound Transmission Class and Outdoor-Indoor Transmission Class ratings from ETS-Lindgren Acoustic Research Laboratory, a nationally accredited testing lab. The tests demonstrated noise dampening capabilities that are increasingly required today in commercial, government and educational building construction. It also meets American National Standards Institute criteria for schools.
