Heat insulating flashing

DETAILED DESCRIPTION The foregoing and other objects and advantages of the present invention are accomplished in a new and improved heat insulating flashing which includes an inner metal element having an outer edge and an outer metal element having an inner edge in spaced apart confronting relation with the outer edge of the inner metal element, and a joining element formed of heat insulating material continuously interconnecting the inner and outer metal elements between the spaced apart edges thereof.
The heat insulating flashing is preferably utilized with heat insulating type wall framing members in curtain wall systems or windows and functions both to divert moisture to the outside of the building, and to reduce heat transfer while at the same time reducing or eliminating the formation of moisture condensation or frost on an inside surface portion of the flashing.
A novel method is provided for making the insulating flashing and a novel apparatus is provided for practicing the method of making the insulating flashing herein disclosed.
The novel method provides for the positioning of a pair of inner and outer metal flashing elements with their facing edges in a spaced apart, aligned, confronting relation and applying thereto a joining element formed of heat insulating material for interconnecting the metal flashing elements between the spaced apart edges.
The novel apparatus for making the heat insulating flashing includes a guide means for aligning the inner and outer metal flashing elements to move longitudinally along parallel paths with their facing edges in confronting, spaced apart, alignment and an applicator for biasing a joining element transversely against the longitudinally moving inner and outer metal elements for permanently interconnecting the metal elements across the spaced apart edges to form the finished heat insulating flashing.
