C-SIP Product Integrates Function and Energy Savings

Composite Panel Building Systems introduces composite structural insulated panels

Composites World, November 17, 2014

Composite Panel Building Systems (CPBS, Corpus Christi, Texas, USA) has launched a fully composite structural insulated panel (C-SIP) designed to deliver superior performance by continuously insulating and sealing the building envelope. According to a CPBS spokesperson, “The C-SIP is unequaled in building science development and engineered with six functions integrated into one building product: exterior sheathing, superior insulation, air barrier, vapor retarder, moisture barrier and structural walls.”

The C-SIP wall panels consist of fiberglass reinforced thermoset polymer (FRT) skins bonded to rigid polyurethane foam by a chemical reaction during manufacturing, which reportedly eliminates any risk of delamination. The C-SIP 4-inch/102mm thick foam core are touted as having an R-value of 26, and will not settle, shrink or lose insulating value over time, providing significant energy savings.

Serving as an air and moisture barrier, the energy efficient C-SIP is designed to replace multiple building products with a single, precision engineered product enabling LEED and NAHB Green Building points.  Many house wraps, water resistive barriers and laminated or fibrous SIPs suffer damage during installation and fail to prevent water intrusion before finish materials are applied. C-SIP wall panels are engineered to withstand the rigors of the construction process without losing performance value, saving time and labor costs by reducing rework.
