Bautex Blocks Create Healthier Buildings by Soundproofing Walls

Con­struct­ing build­ings that pro­tect occu­pants from exces­sive noise is essen­tial in today’s hec­tic world. Noise pol­lu­tion in homes and com­mer­cial build­ings adds to stress and inhibits com­mu­ni­ca­tion. Addi­tion­al­ly and impor­tant­ly, a study by the Uni­ver­si­ty of Michi­gan, Envi­ron­men­tal Health Sci­ence Depart­ment con­clud­ed that tens of mil­lions of peo­ple might be at risk of heart dis­ease along with hear­ing loss from noise pollution.The dis­turb­ing noise that infil­trates build­ings comes from traf­fic, trains, planes, con­struc­tion activ­i­ties, close neigh­bors, and more. Sound­proof­ing exte­ri­or walls is cru­cial to con­trol­ling the lev­el of out­side noise that reach­es the inte­ri­or of a build­ing. Build­ing designs that elim­i­nate or reduce unwant­ed and dis­turb­ing noise from enter­ing a build­ing are essen­tial to the health and well-being of the occu­pants.

Insu­lat­ed con­crete blocks (ICBs) for exte­ri­or walls are pop­u­lar for their ener­gy effi­cient and dis­as­ter resis­tant traits, and also for their noise reduc­ing fea­tures. The con­crete in ICBs reflects noise and the foam insu­la­tion absorbs sound. In fact, a sur­vey con­duct­ed by ICF mag­a­zine found that res­i­dents of homes built with ICB were far more like­ly to com­ment on the quiet­ness of their homes than those liv­ing in wood-framed homes. Addi­tion­al­ly, a com­par­i­son of ICB and wood-frame walls by Port­land Cement Asso­ci­a­tion found that sound pen­e­trat­ed an ICB wall about one-fourth to one-eighth as much as a wood frame wall. Insu­lat­ed con­crete blocks are an excel­lent choice to ensure a sound proof exte­ri­or wall in both res­i­den­tial and com­mer­cial con­struc­tion.

The Bau­tex Wall Sys­tem is an ICB wall assem­bly that sig­nif­i­cant­ly reduces the trans­fer of sound from the out­side to the inside of a structure.The Bau­tex Wall Sys­tem (when fin­ished with one thin lay­er of plas­ter on the inside wall sur­face and thin applied stuc­co on the exte­ri­or wall sur­face) received a high Sound Trans­mis­sion Class (STC)* rat­ing of 51 and a high Out­door-Indoor Trans­mis­sion Class (OITC)** per­for­mance rat­ing of 47. These stan­dards meet and exceed acoustic stan­dards required today in most com­mer­cial, gov­ern­ment and edu­ca­tion­al build­ing con­struc­tion. For exam­ple, the ANSI S12.60Acousti­cal Per­for­mance Cri­te­ria, Design Require­ments and Guide­lines for Schools” aims to cre­ate a class­room envi­ron­ment that opti­mizes com­mu­ni­ca­tion and improves learn­ing. The ANSI S12.60 stan­dard man­dates that exte­ri­or and inte­ri­or walls of offices, con­fer­ence rooms, and main cor­ri­dors in schools obtain a min­i­mum STC of 45 and that class­room walls achieve a min­i­mum STC of 50. Bau­tex Wall System’s STC of 51 exceeds both these stan­dards. The Bau­tex Blocks also cre­ate an inte­grat­ed wall assem­bly that exceeds 2015 build­ing codes for ener­gy effi­cien­cy and safe­ty. Exte­ri­or and inte­ri­or walls in both res­i­den­tial and com­mer­cial con­struc­tion can uti­lize Bau­tex Blocks. The Bau­tex Sys­tems LLC com­pa­ny is head­quar­tered in San Mar­cos, Texas and serves builders through­out the south­west Unit­ed States.

For the com­fort and safe­ty of a building’s occu­pants, sound­proof­ing exte­ri­or walls is an essen­tial part of a building’s design. Exte­ri­or walls con­struct­ed of insu­lat­ed con­crete block can con­trol noise pol­lu­tion bet­ter than wood framed walls. Insu­lat­ed con­crete block walls are also more ener­gy effi­cient and dis­as­ter resis­tant that sim­ple wood framed walls. Decreas­ing noise pol­lu­tion inside a build­ing improves the qual­i­ty of life for the res­i­dents by reduc­ing their stress lev­el, improv­ing com­mu­ni­ca­tion, and less­en­ing the risk of heart dis­ease and hear­ing loss.

*The STC rat­ing indi­cates how much a mate­r­i­al (or wall) reduces a sound as the sound moves through the mate­r­i­al (wall). Cal­cu­la­tion of the STC rat­ing is by the ASTM E-413 Stan­dard. The high­er the num­ber, the bet­ter the noise iso­la­tion.

**The OITC rat­ing indi­cates the rate of trans­mis­sion of sound between out­door and indoor spaces in a struc­ture. Cal­cu­la­tion of the OITC rat­ing is by the ASTM E-1332 Stan­dard. The high­er the num­ber, the bet­ter the noise iso­la­tion.
