Spyder foam was developed expressly for composite construction. It has two times the compressional strength of blue foam and greater shear strength. Spyder foam's unique design incorporates a fine cell structure that is aligned perpendicular to the surface, creating a ridge honeycomb effect. The vertical cell alignment allows for better penetration of resin into the foam's surface thereby enhancing the bond and the shear strength between the foam and the skin. Spyder foam weighs about 10% more than blue foam and can be cut with a hot wire.
