Furring and flashing strip system

Abstract

An insulation furring and flashing strip system adapted for attachment to insulation board, with or without exterior sheathing, exterior siding, metal panels, sheets, roofing, signage or exterior masonry products. The insulated furring and flashing strip system includes insulation foam insulation received inside a U shaped, a Hat shaped, or a trapezoidal shaped metal channel. The insulation foam is bonded to the metal channel. The metal channel includes dimpled screw holes for receiving elongated strip system screws. The screws are used for securing the strip system to wall and roof stud framing. Building wall or roof siding is then attached to metal channel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(10) In FIG. 1A, a perspective view of the insulation furring and flashing strip system is shown having general reference numeral 8. The strip system 8 is shown in this drawing having castellated indents 23 of insulation foam 20 in a metal channel 22 and having a trapezoid configuration. The castellated indents 23 of the insulation foam 20 extends outwardly from the sides of the metal channel 22. Spaced apart recessed dimpled holes 24 are pre-formed into the metal channel 22 to receive elongated screws 26, shown in FIG. 2. The head of the screws sits flush with an outside face of the channel.

(11) 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.

(12) In FIG. 1B, a perspective view of the insulation furring and flashing strip system 8 is illustrated with the metal channel 22 in an inverted U shape configuration. In this drawing, the projecting insulation foam 20 extends outwardly from the sides of the metal channel.

(13) In FIG. 1C, a perspective view of the insulation furring and flashing strip system 8 is shown having the metal channel 22 in a Hat shaped configuration, with aligned insulation foam 20 extend next to a bottom of the sides of the metal channel.

(14) While the system 8 is shown in FIGS. 1A, 1B and 1C, it is not necessarily limited to these three particular geometries and can include a ribbed or a ridged finish and other configurations. Also the aligned insulation foam, shown in FIG. 1C, and projecting insulation foam, shown in FIG. 1B, are primarily intended for vertical applications, while the castellated insulation foam, shown in FIG. 1A, is intended for horizontal application, to provide a drainage path for any condensation behind wall finishes, that drains away from a finish surface and back towards a water and air barrier of the building.

(15) In FIG. 2, the furring and flashing strip system 8 is shown attached to a vertical building framing stud 10. While the stud 10 is shown in this drawing, the strip system can also be used with solid concrete walls, masonry walls, or other structural elements depending on the building structure at a given project. The stud 10 is shown disposed against exterior sheathing 12 and exterior rigid insulation board 14. The exterior sheathing 12 may be omitted and is not a requirement of the subject invention 8.

(16) 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.

(17) In FIG. 3, a perspective view of the furring and flashing strip system 8 is illustrated, as shown in FIG. 2. In this view, the elongated screws 26 and the exterior screws 30 are shown for alternate receipt in the dimpled holes 24. The exterior screws 30, as mentioned above, are used to secure the wall and roof siding 28 to the metal channels 22. The elongated screws 26 are used to secure the metal channels 22 to the framing stud 10.

(18) In FIG. 4, a side sectional view of the furring and flashing strip system 8 is shown, as illustrated in FIG. 3.

(19) In FIG. 5, the insulation furring and flashing strip system 8 is shown in a horizontal orientation and used with the exterior wall or roof siding 28.

(20) In FIG. 6, an alternative application for vertically oriented siding or panels is shown, using spaced apart metal strapping 34 fastened to the metal channel 22 with short screws 35, which will penetrate the flashing barrier 18. Exterior siding or sheeting 36 is then attached to both the vertical furring and flashing strip metal channel 22 and the horizontal metal strapping 34, using the screws 35. Exterior siding or sheeting joints 32 are then aligned over the metal strapping 34

(21) While the invention has been particularly shown, described and illustrated in detail with reference to the preferred embodiments and modifications thereof, it should be understood by those skilled in the art that equivalent changes in form and detail may be made therein without departing from the true spirit and scope of the invention as claimed except as precluded by the prior art.
