Abstract
Abstract A laminated composite sheathing is adapted to provide structural support and resist weakening from weathering by providing a thermally insulating layer of foam bonded on one or both faces to a relatively rigid laminated sheet preferably formed of a fiberboard core adhesively secured between facing sheets of kraft paper bonded together with a resilient polymeric material.

Independent Claim
55 words
A laminated composite sheathing adapted to provide structural support and resist weakening from weathering, comprising: a panel having front and back facing surfaces and formed from a thermal insulating material; and a supporting laminate sheet bonded to at least one of said panel facing surfaces, comprising a water-resistant fiberboard core adhesively secured between facing sheets.
Claim 2
Dependent Claim
55 words
A laminated composite sheathing adapted to provide structural support and resist weakening from weathering, comprising: a panel having front and back facing surfaces and formed from a thermal insulating material; and a supporting laminate sheet bonded to at least one of said panel facing surfaces, comprising a water-resistant fiberboard core adhesively secured between facing sheets.
Claim 3
Dependent Claim
78 words
A laminated composite sheathing adapted to provide structural support and resist weakening from weathering, comprising: a panel having front and back facing surfaces and formed from a thermal insulating material; and a supporting laminate sheet bonded to at least one of said panel facing surfaces, comprising a water-resistant fiberboard core adhesively secured between facing sheets, each of said facing sheets formed from at least two layers of kraft paper bonded together by a layer of a resilient polymer.
Claim 4
Dependent Claim
78 words
A laminated composite sheathing adapted to provide structural support and resist weakening from weathering, comprising: a panel having front and back facing surfaces and formed from a thermal insulating material; and a supporting laminate sheet bonded to at least one of said panel facing surfaces, comprising a water-resistant fiberboard core adhesively secured between facing sheets, each of said facing sheets formed from at least two layers of kraft paper bonded together by a layer of a resilient polymer.
Claim 5
Dependent Claim
12 words

Claim 7
Dependent Claim
22 words
The laminated sheathing of claim 2, wherein said supporting laminate sheet is bonded to both facing surfaces of the thermal insulating panel.
Claim 8
Dependent Claim
24 words
The laminated sheathing according to claim 2, wherein said supporting laminate sheet is bonded to only one facing surface of the thermal insulating panel.
Claim 9
Dependent Claim
22 words
The laminated sheathing according to claim 4, wherein the expanded foam panel has a thickness from approximately 0.25 inch to four inches.
