ABSTRACT:
A foam composite - especially useful as an insulating board - comprising first and second oppositely disposed corrugated skins having a core of foam material therebetween, and a reinforcement medium located at the interface between the foam core and each skin, the foam extending through interstices or pores in the medium and bonding to the medium and to the skins. The reinforced composite so formed has increased resistance to bending and other deformations and improved dimensional stability.
