Composed of resin-bonded glass fibers in a range of densities, CertaPro® Board can be used to add both thermal insulation and sound absorption to interior spaces. CertaPro board stiffness ranges from rigid to more flexible for curved and/ or sharp-edged applications. It is available unfaced, for use where an exterior finish will be applied, or faced with a vapor retardant finish in either a clean metallic (FSK) or attractive white (ASJ) surface. CertaPro® boards are easy to cut to size and shape and to install. Additionally, unfaced and FSK faced CertaPro® board are compliant where a fire hazard classification of 25/50 is required, can be used for exposed or non-exposed applications, resist mold and mildew and will not rot of deteriorate.

  • Available in faced (FSK or ASJ) or unfaced


Exterior walls The faced side of the board should be installed toward the interior side of the structure, except in some warm and humid areas where local practice and/or building codes may require a vapor retarder to be outside the heating or building envelope. Curtain walls CertaPro Commercial Board is applied to spandrel and pre-cast concrete panels with approved adhesives or mechanical fasteners. Follow the fastener manufacturer’s recommendations for pin terminations and safety considerations. Boards may also be installed using hat channels or Z studs. For applications involving low perm (< 1.0) exterior finishes, consideration should be given to taping or sealing all seams, joints and penetrations or for providing a separate continuous vapor retarder system. Consult your architect for specific vapor retarder requirements. These installation recommendations are general in nature. Other methods are acceptable. Please consult local building codes for recommendations best suited to the application.
