Claim 1
Independent Claim
162 words
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.
Claim 2
Dependent Claim
162 words
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.
Claim 3
Dependent Claim
49 words
An article as claimed in claim 1 wherein said nailing section has a minimum thickness of about one-half the maximum thickness of the article and the length of the tapered portion of the nailing section is about one-half the length of the exposed outer surface of the butt section.
Claim 4
Dependent Claim
49 words
An article as claimed in claim 1 wherein the tapered portion is cut at an acute angle relative to the inner surface, the tangent of said angle approximating the ratio of the maximum thickness of the article to the length of the exposed outer surface of the butt section.
Claim 5
Dependent Claim
22 words
An article as claimed in claim 3 wherein the length of the tapered portion is about one-fifth the length of the article.
Claim 6
Dependent Claim
28 words
An article as claimed in claim 3 wherein the minimum thickness of the article is about one-quarter inch and about one-half of the maximum thickness of the article.
Claim 7
Dependent Claim
19 words
An article as claimed in claim 1 wherein said exposed outer surface has the appearance of a wood shake.
Claim 8
Dependent Claim
26 words
An article as claimed in claim 1 wherein the insulating board contains up to about 7% gypsum and up to about 1% fly ash by weight.
