Composite Panel Building Systems (CPBS) introduced a fully composite structural insulated panel (C-SIP) designed to continuously insulate and seal the building envelope. The C-SIP is engineered with six functions integrated into one product, including the exterior sheathing, 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 eliminates any risk of delamination. The C-SIP 4″ foam core 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 replaces multiple building products with one, 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 or cutting re-work, saving time and labor costs.

Eco-friendly composite FRT channels from Bedford are used to join the C-SIP wall panels together andattach to the foundation, floor system and roof structure as well as pultruded composite frame windows. The FRT channels eliminate the use of wood or metal connection materials, which are susceptible to rot, termite or insect infestation, mold and moisture penetration that can dramatically weaken the structure. The structural walls in the C-SIP system eliminate the need to convert studs to expensive 2 x 6 framing, in order to meet progressing energy codes with the added cost of extra insulation.
