A siding panel formed from a body of hardboard material is formed with a locking tongue at or adjacent its upper edge and a locking seat at its lower edge. The locking tongue of one panel is arranged to be seated in the locking seat of another panel when adjacent panels are arranged with their marginal edge portions overlapping one another in use. The locking seat is in the form of a notch which is formed in the back face of the body of the panel. The notch extends upwardly from the lower edge and underlies the lower marginal edge portion of the panel.

A siding panel for selective attachment to an underlying support surface comprising; a unitary body of hardboard material having a front face, a back face, an upper edge and a lower edge, and upper and lower marginal edge portions extending inwardly from said upper and lower edges respectively, said upper edge of said body being bevelled to provide a V-shaped locking tongue, said bevelled upper edge extending downwardly and rearwardly from adjacent said front face of the panel to said back face to thereby form a line contact which engages the underlying support surface when said body is selectively attached to the support surface, a locking seat in the form of a notch formed in the back face of said body and extendingly upwardly from said lower edge to underlay said lower marginal edge portion, said body having a uniform thickness between said upper and lower marginal edge portions which is in the range of about 0.375 to 0.5 inch, said bevelled upper edge being bevelled with respect to said front face of said body at a first acute angle and said notch being defined by a second acute angle wherein said second acute angle is greater than said first acute angle, said second acute angle being approximately 35°to 40°with said first acute angle being approximately 5°to 10°less than said second acute angle and said notch having a depth measured from said back face which is not greater than that which reduces the thickness of the lower marginal even portion to about 0.1875 inch such that when the locking tongue of one panel is seated in the locking seat of a second panel when adjacent panels are arranged with their marginal edge portions overlapping one another on the support surface, the greater thickness of said upper marginal edge will serve to space a substantial portion of said back face of said second panel from the support surface to create a drying air gap therebetween with the line contact of said one panel being adjacent said lower edge of said second panel.
