Modular sandwich panel and method for housing construction.

A. composite panel (1) comprising at least two spaced apart outer laminates (2, 3) and a core laminate (4) sandwiched therebetween. The outer laminates (2, 3) and the core laminate (4) are off-set such that portions (5, 6) of the outer laminates protrude beyond the core by a predetermined margin (A) along a first edge of the panel and such , that the core laminate (4) protrudes beyond the outer laminates by a generally corresponding margin (B) along an opposite edge (7) of the panel. The protruding portions of the outer laminates of one panel are adapted nestingly to receive and locate a complementary protruding core portion of an adjacent like panel in interlocking relationship to form a composite panel assembly.
