Abstract

A manufacturing process appropriate for use in constructing laminated structures for use in building construction such that the laminating steps to not require elevated drying temperatures or an extended dwell time at any point. This is accomplished using a specially formulated viscoelastic glue and ambient temperature drying apparatus. As a result, the production capacity of the manufacturing process is greatly improved over existing methods.
