Bautex Wall System Stands Strong Against Dangerous Debris Impact at Speeds Greater Than 100 MPH

Bautex Block is key component in wall system that provides structure, envelope, continuous insulation, fire resistance, and air and moisture barrier – all in a single integrated assembly.

A wall sys­tem with Bau­tex Block has more wind­storm pro­tec­tion than you can shake a stick – or two-by-four – at. Affirm­ing its dura­bil­i­ty and supe­ri­or storm pro­tec­tion com­pared to oth­er build­ing envelopes, a Bau­tex Wall Sys­tem with Bau­tex Block passed hur­ri­cane and tor­na­do debris impact tests with fly­ing col­ors.

Tests were per­formed at the Wind Sci­ence and Engi­neer­ing Research Cen­ter Debris Impact Test Facil­i­ty and the Nation­al Wind Insti­tute at Texas Tech Uni­ver­si­ty in Lub­bock, Texas. Tests were con­duct­ed in accor­dance with the debris impact guide­lines of FEMA P320/P361 (2008) and ICC-500 (2008) for hur­ri­canes and tor­na­dos. ICC-500 includes a hur­ri­cane build­ing enve­lope stan­dard that is required by Flori­da Build­ing Code and Texas Depart­ment of Insur­ance Wind­storm Resis­tant Con­struc­tion Guide.

Whether design­ing struc­tures to with­stand the storms along the Atlantic Ocean, Gulf of Mex­i­co or the plains of Texas and Okla­homa, archi­tects have a new build­ing enve­lope solu­tion that meets or exceeds storm shel­ter and safe room require­ments,” says Paul Brown, pres­i­dent of Bau­tex Sys­tems. Rather than retro­fitting exist­ing build­ings to pro­vide storm shel­ters for occu­pants, which can be com­plex and expen­sive, an entire build­ing project can be con­struct­ed to these wind­storm debris impact stan­dards using a Bau­tex Wall Sys­tem. The struc­ture also gains mea­sure­able ben­e­fits in ener­gy effi­cien­cy and fire safe­ty.”

In the tests con­duct­ed at Texas Tech Uni­ver­si­ty, Bau­tex Wall Sys­tems with Bau­tex Block were test­ed for hor­i­zon­tal debris impact, with the fol­low­ing results:

  • Bare wall meets and exceeds Pro­to­col 1, a hur­ri­cane build­ing enve­lope stan­dard, as required by Flori­da Build­ing Code and Texas Depart­ment of Insur­ance Wind­storm Resis­tant Con­struc­tion Guide;
  • Bare wall meets Pro­to­col 2 and ICC-500 stan­dard for hur­ri­cane shel­ters, for sus­tained hur­ri­cane wind speeds up to 225 mph, in accor­dance with the ICC/NSSA Stan­dard for the Design and Con­struc­tion of Storm Shel­ters;
  • With mason­ry veneer, a Bau­tex Wall Sys­tem meets Pro­to­col 3 for FEMA 320/FEMA 361 stan­dard for hur­ri­cane safe rooms for wind speeds up to 225 mph.

To test per­for­mance under tor­na­do wind con­di­tions, two test walls were con­struct­ed: a wall with Bau­tex Block and fin­ished with brick veneer and a wall with Bau­tex Block fin­ished with CMU hol­low block veneer. These walls received the fol­low­ing test results:

  • Meets pro­to­col 4 for ICC-500 stan­dard for tor­na­do shel­ters for wind speeds up to 225 mph
  • Meets pro­to­col 4 for FEMA 320/FEMA 361 stan­dard for tor­na­do safe rooms for wind speeds up to 250 mph

The Bau­tex Wall Sys­tem and its Bau­tex Block out­per­formed many of its com­peti­tors that also test­ed prod­ucts at Texas Tech University’s Nation­al Wind Insti­tute. While many wall assem­blies con­struct­ed with brick or mason­ry veneer have failed to achieve high­er debris impact results, both of the Bau­tex Block test walls test­ed suc­cess­ful­ly with debris impact speeds well over 100 mph, with no fail­ure.

The indus­try is always reeval­u­at­ing how to build in storm prone areas, and we’re proud to pro­vide a well-test­ed build­ing enve­lope solu­tion that can pro­vide mul­ti­ple effi­cien­cy and life safe­ty ben­e­fits from a sin­gle inte­grat­ed assem­bly,” Brown says.
