Building panel

An insulated, one-side finished, building panel, the panel having:

• an inner, relatively thick, insulation base and an outer, relatively thin, finish layer;
• the finish layer comprising a finish material, the finish layer securely adhered to one surface of the insulation base;
• the panel having outer and inner surfaces and top, bottom and side edges, the outer surface of the panel formed by the outer surface of the finish layer to provide an outer finished surface on the panel;
• top and bottom interconnecting means on the top and bottom of the panel, the top interconnecting means having an upwardly directed top flange with one side of the flange formed by the inner surface of the panel, the other side of the flange extending downwardly;
• a slot adjacent the other side of the flange below the top of the flange and extending downwardly, narrowing toward its bottom;
• the top of other side of the slot connected by an angled top surface that extends downwardly and outwardly from the slot to the front surface of the panel;
• and a groove forming section provided at the corner between the angled top surface and the front surface of the panel.

A building panel assembly comprising first and second panels, each panel having:

• an inner, relatively thick, insulation base and an outer, relatively thin, finish layer;
• the finish layer comprising a finish material securely adhered to one surface of the insulation base;
• the panel having outer and inner surfaces and top, bottom and side edges, with the top and bottom sides of the finish layer forming part of the top and bottom edges of the panel;
• the outer surface of the panel, extending between the top and bottom edges, being formed by the outer surface of the finish layer to provide an outer finished surface on the panel;
• top and bottom interconnecting means on the top and bottom of the panel, the interconnecting means integral with the base;
• the corners between the outer surface of the panel and the top and bottom edges shaped into groove forming sections;
• the bottom interconnecting means of the second panel connected to the top interconnecting means of the first panel to have bottom edge of the second panel abut the top edge of the first panel and to have the groove forming sections form a groove between the panels with the joint between the panels located in the groove.
