Cement backer board products are a recommended substrate for exterior adhered applications of thin set veneer products.  Meeting continuous insulation requirements can be difficult when considering these applications.  GTM Architects utilized TClear ProGUARD Concrete Insulated Sheathing wall panels consisting of a lightweight non-structural, impact resistant concrete backerboard sheet laminated to a continuous layer of rigid insulation for the adhered installation of thin limestone veneer on the Educational Systems Federal Credit Union in Germantown, Maryland.

ProGUARD simplifies designs utilizing adhered thin stone veneer, thin brick, exterior tile and stucco applications while meeting ASHRAE 90.1 continuous insulation requirements.  Insulated concrete panels can be applied direct to studs or over sheathing applications where required and can be designed to meet NFPA 285.
