Abstract
A core for a patio enclosure wall includes a first layer formed of polyisocyanurate material and a second layer formed of plasterboard bonded to the first layer. The core may be sandwiched between a weather resistant exterior panel and an interior surface to form a panel/core assembly for a patio enclosure wall. The core of the present invention provides fine thermal insulation. The plasterboard components serve to prevent the spread of flames. Furthermore, the core serves as an efficient sound barrier.
