Abstract
Abstract A prefabricated, insulated building panel formed from an outer facing sheet which may be profiled and an inner facing sheet, wherein the opposed first edges of the facing sheets are connected by an S-shaped non-metallic flexible strip, and the opposite or opposed second edges of the facing sheets are spacedapart. An insulating core, for example, foamed-in-situ polyurethane, bonds the facing sheets one to the other and serves as thermal and sound insulation and to rigidify the panel. Where the outer facing sheet is profiled, the insulating core may fill less than the entire space between the facing sheets. A tongue and a groove are presented along the opposite longitudinal sides of the panel. A segment of the flexible strip is presented within the groove. The tongue and a groove are arranged to provide a laterally adjustable, weather-tight joint between adjacent panels.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
157 words
A building panel comprising: a liner sheet and a facing sheet having central webs disposed in spaced-apart confronting relation and presenting opposed first longitudinal sides and opposed second longitudinal sides; a foamed plastic core disposed between and bonded to the liner and facing sheets; side walls, one connected to each of said first longitudinal sides and extending toward the other sheet; terminal flanges, one connected to each of said side walls, said terminal flanges confronting one another and extending in opposite directions generally parallel with said central webs; an S-shaped non-metallic flexible strip having oppositely opening recesses; one of said terminal flanges extending into each of said oppositely opening recesses; said opposed second longitudinal sides being spaced-apart; a tongue including said second longitudinal sides; and a longitudinal recess presented between said first longitudinal sides and being defined in part by a flexible strip segment of said S-shaped non-metallic strip and the side wall of said liner sheet.
Claim 2
Dependent Claim
157 words
A building panel comprising: a liner sheet and a facing sheet having central webs disposed in spaced-apart confronting relation and presenting opposed first longitudinal sides and opposed second longitudinal sides; a foamed plastic core disposed between and bonded to the liner and facing sheets; side walls, one connected to each of said first longitudinal sides and extending toward the other sheet; terminal flanges, one connected to each of said side walls, said terminal flanges confronting one another and extending in opposite directions generally parallel with said central webs; an S-shaped non-metallic flexible strip having oppositely opening recesses; one of said terminal flanges extending into each of said oppositely opening recesses; said opposed second longitudinal sides being spaced-apart; a tongue including said second longitudinal sides; and a longitudinal recess presented between said first longitudinal sides and being defined in part by a flexible strip segment of said S-shaped non-metallic strip and the side wall of said liner sheet.
Claim 3
Dependent Claim
31 words
The building panel of claim 1 wherein the terminal flange of said facing sheet is positioned between the central web of said facing sheet and the terminal flange of said liner.
Claim 4
Dependent Claim
19 words
The building panel of claim 1 wherein said flexible strip segment includes flexible fingers extending into said longitudinal recess.
Claim 5
Dependent Claim
35 words
The building panel of claim 1 including a re-entrant sheet portion connecting the side wall and the first longitudinal side of said liner sheet, said re-entrant sheet portion providing one face of said longitudinal recess.
Claim 6
Dependent Claim
34 words
The building panel of claim 1 wherein the central web of said facing sheet is profiled; and wherein said foamed plastic core fills less than the entire space between the liner and facing sheets.
Claim 7
Dependent Claim
20 words
The building panel of claim 1 wherein said opposed second longitudinal sides are connected solely by said foamed plastic core.
Claim 8
Dependent Claim
25 words
The building panel of claim 1 wherein said facing sheet includes an edge strip extending from the second longitudinal side into the foamed plastic core.
