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.
