Abstract of the Disclosure A thermal barrier member or shape of plastic or other suitable insulating material having a plurality of small flat-faced surface protrusions or projections thereon located at selected areas on the member is provided for joining metal members of a window or door frame together. End portions of the projections are adapted to be shaved off or sheared to form the flat faces when the thermal barrier member is joined to the metal members. The insulating member is slidably longitudinally joined to the metal members. The receiving metal members are adapted to receive the thermal barrier member and the receiving areas are of such a size that the end portions of the small projections on the thermal barrier member are shaved off in the joining process. Such construction provides a tight or interference fit between the metal members and the thermal barrier member thereby providing a unitary thermo break or thermal barrier construction. Greater dimensional variations in either the insulating member or the metal members are permissable with the invention.
