Abstract

Abstract A permanent wall form for construction of a concrete wall including expanded metal lath side members tied in spaced-apart relationship by wire truss members in place intermediate the metal laths. Channels on the lath receive the inserted truss members for secure assembly of the lath side members. The lath permits migration of the concrete therethrough for subsequent smooth finishing by troweling. Provision is made for the including of insulative strips on one side of the form prior to concrete pouring.
