A B S T R A C T A sill and frame for windows or doors have front and rear sections and connecting elements therebetween to which the sections are connected. In order to produce the sill and frame at substantially lower costs than for conventionally manufactured sections and in a manner that saves material, each section has been formed by roll forming to provide two shanks which provide a double-walled support portion for mounting seals or build-up sections for seals. The shanks, in connection with the support portion, are extended to form coupling portions for connecting the shanks to the connecting elements.
