BUILDING SURFACE PANELS WITH AGED FOAM BACKING AND METHOD OF MANUFACTURE

原文（中国語）

The present disclosure relates generally to cladding for covering a building surface. The present disclosure relates more particularly to a method of manufacturing a building surface panel. The method includes providing a foam piece having a 30 day/23° C. residual shrinkage of no more than 0.2%. The foam piece having the 30 day/23° C. residual shrinkage of no more than 0.2% is attached to a rear side of an outer shell so as to form the building surface panel. In some embodiments, a front side of the outer shell forms a visible surface of the building surface panel. The foam piece can be provided, e.g., by aging the foam piece for a time and at a temperature such that the 30 day/23° C. residual shrinkage is no more than 0.2%. The foam piece to be aged can, in some embodiments, be cut from a body of foam.
