1. A composite siding panel comprising:

  • an outer panel formed of a weather impervious material and having first and second spaced, longitudinally extending edges;

    means defining a nailing strip on one of the first and second longitudinal edges of the outer panel for mounting the outer panel on a building;

    an elongated insulating member formed of a foamed insulating material mounted on the inner surface of the outer panel, the insulating member having first and second longitudinally extending edges;

    an under cut recess formed in and extending along the first longitudinal edge of the insulating member said recess having a plurality of sides of which one side forms an acute angle at the junction of said composite siding panel and building;

    a projection complementary to the recess formed in and extending along the second longitudinal edge of the insulating member, the projection extending outward beyond one edge of the outer panel a greater distance than the depth of the under cut recess; and

    first and second interlocking means extending along opposed first and second longitudinal edges of the outer panel for interlocking outer panels of two adjacent panels in parallel, abutting relationship, the first interlocking means being disposed within the recess in the insulating member;

    the width of the insulating member being greater than the width of the outer panel by a pre-determined amount such that the adjacent longitudinal edges of two insulating members are compressed against each other upon the interlocking of two adjacent siding panels to which the insulating members are mounted.
