Roofing or siding article
First Claim
1. A weather and fire-resistant roofing or siding article such as a shingle or panel having high thermal insulation value, comprising:
- (a) a body having opposed inner and outer surfaces composed of insulating board comprising fiber, binder and about 50 to about 90% by weight expanded perlite;
(b) said body having a butt section and an adjacent nailing section, the butt section being substantially uniformly the maximum thickness of the article and having a non-tapered outer surface to be exposed to the weather, said nailing section being of the same thickness as the butt section at the juncture with said butt section, having a non-tapered outer surface, and having an inner surface tapered in thickness in a portion thereof from said maximum thickness to a minimum thickness at one edge thereof remote from said juncture; and
(c) a water and weather-resistant coating comprising asphalt and roofing granules on the outer surface of said uniform thickness butt section to be exposed to the weather.

Abstract
A weather and fire-resistant roofing or siding article, such as a shingle or panel, having a high thermal insulation value is cut from insulating board comprising fiber, binder and about 50 to 90% by weight expanded perlite. The article has adjacent butt and nailing sections, the butt section being substantially uniformly the maximum thickness of the article and having a water- and weather-resistant coating composition on the outer surface to be exposed to the weather, and the nailing section having a non-tapered outer surface and an inner surface tapered from the maximum thickness at the junction of the two sections to a minimum thickness at the edge of the article. The outer surface of the butt section may be machined or pressed or embossed to provide a decorative surface simulating a wood shake, and coated with a sun- and moisture-proof coating such as asphalt and roofing granules.
