Serge You will have to look at Eduardo's site to get the particulars. But yes the foam gets sandwiched between the wooden frame pieces, and then sanded down flush with the wood. Then the glass is applied inside and out. The Vision uses the same procedure as Dr Dean, just without using the dimensions of the KR2 or S model. You create a jig to shape out of wooden stringers, then apply 1/2 Lastofoam to the shape, and then glass the outside. After cure, use the female supports to rest the sured outer shell in, and glass the interior. Strength is increased if you use a spruce longeron on top of the shell, as you do when building the wooden frame. This is also the procedure followed by the Cozy builders. I think Eduardo's idea is the strongest, incorporating the best of both construction methods. This could help keep ones cost down if wood is hard to get. I really enjoy working with the glass more than anything else, so my next project will be all glass most likely, even if it is a KR2S modified. Plus down here in Florida, it won't rot or corrode!
