This invention relates to a furring and flashing strip system for exterior finish of a habitable building and construction of similar wall and roof building structures. The strip system allows for simplification of current construction practices, and reduces and/or eliminates problematic issues such as maintaining a continuous insulation envelope. Also the system provides a tight air and water barrier, as required for energy code compliance. Further, the system provides for required thermal performance, and structural support of cladding systems.
Still further, the strip system provides for a robust means for attachment to a siding or sheet roofing product, thin set masonry, and full brick and stone masonry. Yet further, the strip system can be part of a support system for a roofing deck or standing seam metal roof panels, standing seam metal wall panels, signage, solar panels, skylights, and items attached to a building structure. Even further, the system can be utilized in a building interior for support of ceiling systems, interior wall sheeting for increased thermal and acoustical separation, signage, and similar products used in a building interior.
Heretofore, there have been a large number of issued patents and published patent applications related to exterior insulation, cladding attachment systems and related products.

None of the above mentioned prior art references disclose the unique features, objects and advantages of the subject insulation furring and flashing strip system as disclosed herein.
A primary object of the subject insulation furring and flashing strip system is to provide a system for exterior and interior finish of a building structure, which allows for simplification of current construction practices, reduces and/or eliminates problematic issues such as maintaining a continuous insulation envelope.
Another object of the furring and flashing strip system is it maintains a tight air and water barrier for improved thermal performance of the building structure.
Still another object of the system is to provide a more robust and improved means for attachment to wall and roof sheet siding, or exterior cladding materials such as brick masonry.
Further, another object of the system is it can be used as a support system for signage, solar panels, skylights, and other such items attached to a building structure.
The subject insulation furring and flashing strip system is adapted for attachment to an insulation board, with or without exterior sheathing and exterior siding. The strip system includes foam insulation received inside a “U” shaped, or a “C” shaped, or a “Hat” shaped, or a trapezoidal shaped metal channel and bonded thereto. The metal channel includes spaced apart, dimpled screw holes for receiving elongated screws for securing the strip system to the structure directly, or a structure behind the insulation board. Exterior siding or other exterior wall or roof products discussed above are then attached to the metal channel. The insulation foam can be flush with sides of the metal channel or projecting outwards from the sides of the metal channel. The projecting insulation foam provides for additional thermal separation from an exterior wall or roof system, or for metal building components such as a prefabricated metal building, or for thermally separate roof panels or wall panels.
These and other objects of the present invention will become apparent to those familiar with various types of insulation furring and flashing systems used in building construction when reviewing the following detailed description, showing novel construction, combination, and elements as herein described, and more particularly defined by the claims, it being understood that changes in the embodiments to the herein disclosed invention are meant to be included as coming within the scope of the claims, except insofar as they may be precluded by the prior art.
The accompanying drawings illustrate complete preferred embodiments in the present invention according to the best modes presently devised for the practical application of the insulation furring and flashing strip system as described herein:
In
An optional air/water flashing barrier 18 is applied to an underside of the insulation foam 20. The flashing barrier 18 is placed against the building and serves to seal seams of insulation without adding additional flashing. Castellated indentations or grooves 23 are formed into the insulation foam 20 to allow for drainage. The grooves 23 can be formed in various sizes depending on the fabrication process and drainage requirements. At the castellated orientation, sides of the metal channel 22 are skewed slightly outward at angle 31 to allow for moisture or condensation to move or flow away from the exterior siding and flow back and down towards an air barrier and out commonly provided weep holes at a bottom of exterior wall system.

While the system 8 is shown in
In
In this drawing, the elongated screws 26 are used for securing the strip system 8 through the insulation board 14 and attached to the framing stud 10. The flashing barrier 18 is self-sealing, such that screw penetration does not compromise the exterior weather barrier. Exterior wall or roof siding 28 is then attached to the metal channel 22 using short exterior screws 30. The exterior screws 30 do not penetrate the integral flashing barrier 18, maintaining weather protection while providing adequate structural attachment. The screws 30 are staggered along a length of the metal channel 22 with the elongated screws 26 to avoid fastener conflict.
