Was in search of foam and came across spyder foam. It seemed like a good alternative but rather expensive.
Does anyone have any info on where to get it,how it works?
It’s been discussed a bit in the archives, but in a nutshell, it doesn’t have the delam problem of the Dow blue insulation foam. The downside, besides the price, is that it’s 3 times heavier than the blue insulation foam. It might work good skinning EPS in a sandwich board. I think Mr. J has used it quite a bit.
Spyder Foam was tried and discarded by the industry more than a decade ago (doesn’t mean it not worth another experiment) probaly due to cost & performance. People I know who shaped it hated it.

A new product developed expressly for composite construction. Spyder foam 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 alinged perpendicular to the wing surface, creating a ridge honeycomb effect. The vertical cell alignment allows for better penetration of the EZ-LAM epoxy resin into the foam’s surface thereby enhancing the bond and the shear strength between the foam and the wing skin.
Spyder foam weighs about 10% more than blue foam, but due to it’s higher strength ,lighter laminates can be used for wing skins resulting in a lighter and stiffer wing . Spyder foam can be cut with a hot wire in the same manner as blue foam.
