Insulated panel

An insulating building panel wherein side edges of the panel are connectable to a like adjacently positioned second insulated panel to a form a building system, the panel comprising:

• a central core of insulating material including first and second major, flat surfaces and side faces;
• first and second relatively thin, substantially flat and oppositely positioned metallic sheets attached to said first and second major surfaces of said central core of insulating material respectively, said flat metallic sheets forming male and female side edge connectors adapted to be respectively joined to female and male side edge connectors of a like adjacently positioned panel to form said building system;
• said male side edge connectors being formed integrally with said oppositely positioned thin metallic sheets to form mirror image male connectors, each of said male connectors including an internal, generally convex curved surface;
• said female side edge connectors being formed integrally with said oppositely positioned thin metallic sheets to form mirror image female connectors, said female connectors including an externally facing generally V-shaped valley formed with an internally curled end portion which provides an externally curved connector area and which terminates outwardly spaced from a side edge of said central core;
• said internal curved surfaces of said male connectors of said panel being capable of sliding over externally curved connector areas of internally curled end portions of female connectors of a like adjacently positioned panel such that said internal curved surfaces of said male connectors are adapted to nest in said V-shaped valleys of female connectors of a like adjacently positioned panel, one of said side faces of a like adjacently positioned panel core being positionable substantially adjacent to a side face of said central core of said panel, said V-shaped valley on an upper female connector adapted to cooperate with an internal, generally curved surface of an upper male connector of a like adjacent panel to form an elongated space which functions as a first gutter system, and said internally curved end portion of a bottom female connector functioning as a second gutter system to avoid or minimize leakage and condensation whenever said panel is used with an adjacent like panel as combination roof and ceiling members.
