Continuous Insulation Improves Efficiency and Exceeds Building Codes

Building owners benefit from years of greatly reduced energy costs

Archi­tects and con­trac­tors that spec­i­fy the use of con­tin­u­ous insu­la­tion can improve ener­gy effi­cien­cy while meet­ing the increas­ing­ly strin­gent spec­i­fi­ca­tions of recent build­ing codes. The Bau­tex Wall Sys­tem pro­vides any build­ing with an R‑14 con­tin­u­ous­ly insu­lat­ed wall sys­tem.

In wall sys­tems with fram­ing mem­bers that span the width of the wall (such as wood fram­ing, steel fram­ing, CMU, tilt pan­el), adding a lay­er of con­tin­u­ous insu­la­tion to the out­side of the wall becomes absolute­ly crit­i­cal for ener­gy effi­cien­cy.

For exam­ple, in a com­mer­cial build­ing locat­ed in Cen­tral or South Texas (2012 IECC cli­mate zone 2) built with wood fram­ing, the pre­scrip­tive R‑value tables require either an R‑20 cav­i­ty insu­la­tion, or a com­bi­na­tion of R‑13 cav­i­ty insu­la­tion and an addi­tion­al R‑3.8 of con­tin­u­ous insu­la­tion on the out­side of stud mem­bers.

In build­ings with met­al-stud con­struc­tion in the same region, the pre­scrip­tive code requires an R‑5.0 con­tin­u­ous insu­la­tion in addi­tion to the R‑13 cav­i­ty insu­la­tion that is usu­al­ly spec­i­fied.

The Bau­tex Wall Sys­tem pro­vides any build­ing with an R‑14 con­tin­u­ous­ly insu­lat­ed wall sys­tem. Bau­tex enables archi­tects and con­trac­tors to be con­fi­dent that the build­ing will sur­pass the ener­gy effi­cien­cy demands of even the most strin­gent build­ing codes. And build­ing own­ers will real­ize years of sub­stan­tial, reli­able sav­ings from reduced ener­gy costs.
