Interlocking vinyl siding panels are formed from vinyl sheets. A sheet of vinyl is extruded with a V-shaped bend along one of its edges, and a Z-shaped bend intermediate its edges. The extruded sheet of vinyl is then formed, while in a hot, semi-viscous state into the final siding profile. As the siding profile is formed, the V-shaped bend is formed into a first locking profile and the Z-shaped bend is formed into a second locking profile. The first locking profile is dimensioned for a snap-type engagement with the second locking profile of another similarly formed siding member.

A method of forming a vinyl sliding member having first and second locking profiles dimensioned so that the first locking profile can have a snap-fit interlock with the second locking profile on a similar siding member when said siding members are installed in parallel relation on a building, comprising the steps of extruding a sheet of vinyl with a first bent portion adjacent one of its edges and a second bent portion intermediate its edges, and thereafter forming the extruded sheet of vinyl into a siding profile, the forming of the extruded sheet of vinyl into the siding profile including the steps of (i) bending the end of the extruded sheet of vinyl having the first bent portion into a first locking profile which incorporates the first bent portion and (ii) bending the intermediate portion of the sheet of vinyl having the second bent portion into a second locking profile which incorporates the second bent portion, the second locking profile being dimensioned to have a snap-fit interlock with the first locking profile of a similarly formed siding member which interlock is provided by contact between said first bent portion and said second bent portion during installation.
