"It is made from 100% post consumer paper products and formed into a honey-comb grid, then two pieces are glued together to make one 3/4" thick sheet.
We then treat these 'gridcore' panels as sheets of plywood used to make traditional SIPs. We created a form that holds two gridcore sheets 6" apart and then sprayed in a soy-based foam insulation which adhered to both sheets of gridcore making our Structural Insulated Panels.
Electrical conduit chases were placed according to our electrical layout prior to spraying foam. We used cardboard poster tubes as the conduit material, and typical plastic outlet boxes cut through the gridcore.
We will seam together our SIPs with an I-Beam type stud at every four footincrement between SIPs. These are made from simple 2x4's and OSB glued together to make an I-beam shape that will slip into the adjacent SIP's.
Unlike traditional SIP's, our panels will also be attached by a top and bottom 2x6 plate which will run the length of each wall. The beauty of this system is the light weight, extreme insulation (6" = approx. R-40) and the gridcore surfaces are of finish quality, they can be painted just like drywall!"
