J-channel backer material
A finishing member for masonry walls allows for simple installation and accurate placement of caulking around windows and doors in cavity wall construction. This invention accommodates a wide variety of window or door frame profiles, particularly those having an outwardly directed channel such as so called J-channel frames, for the detailing and finishing work required for proper installation of a window or door into a masonry veneer or cavity wall construction without requiring a highly skilled and labor intensive installation.
1. A cavity wall construction comprising:
a first wall;
a second wall generally parallel to and spaced from the first wall;
wherein the second wall is comprised of courses of masonry units held together with mortar;
an opening in the first and second walls, the opening including spaced jambs on opposite sides of the opening;
a frame sized and configured to fit within the opening, the frame having an outwardly directed channel; and
at least one finishing member positioned at a juncture between the frame and one of the jambs of the opening, a first leg of the finishing member being interposed in the outwardly directed channel of the frame and a second leg of the finishing member being juxtaposed to the second wall to thereby provide a transition from the frame to the second wall;
the finishing member further comprising a terminal end portion and a frangible connection joining the terminal end portion to a remainder of the finishing member;
wherein the terminal end portion is adapted to be removed along the frangible connection and thereby reveal a recess at a juncture adjacent to the frame, the remainder of the finishing member and one of the jambs of the opening.
2. The cavity wall construction of claim 1 further comprising:
a bead of caulk positioned in the recess and sealing the juncture between the frame and the second wall.
3. The cavity wall construction of claim 1 wherein the first and second legs are generally perpendicular to each other.
4. The cavity wall construction of claim 1 wherein the opening is one of a window opening and a door opening and the frame is a J-channel frame for one of a window and a door.
5. The cavity wall construction of claim 1 wherein the finishing member is a closed cell foam material and the frangible connection comprises perforations in the closed cell foam material.
6. A cavity wall construction comprising:
a first wall;
a second wall generally parallel to and spaced from the first wall;
wherein the second wall is comprised of courses of masonry units held together with mortar;
an opening in the first and second walls, the opening including spaced jambs on opposite sides of the opening;
a frame sized and configured to fit within the opening, the frame having an outwardly directed channel;
wherein the opening is one of a window opening and a door opening and the frame is a J-channel frame for one of a window and a door;
at least one finishing member positioned at a juncture between the frame and one of the jambs of the opening, a first leg of the finishing member being interposed in the outwardly directed channel of the frame and a second leg of the finishing member being juxtaposed to the second wall to thereby provide a transition from the frame to the second wall
a terminal end portion of the second leg;
a frangible connection joining the terminal end portion to a remainder of the finishing member;
wherein the terminal end portion is adapted to be removed along the frangible connection and thereby reveal a recess adjacent to the frame, the remainder of the finishing member and one of the jambs of the opening; and
a bead of caulk positioned in the recess and sealing the juncture between the frame and the second wall.
7. A frame assembly adapted to be installed into an opening in a wall, the frame assembly comprising:
a frame sized and configured to fit within the opening, the frame having an outwardly directed channel along at least one side thereof; and
at least one finishing member adapted to be positioned at a juncture between the frame and one of the jambs of the opening, the finishing member having a first leg interposed in the outwardly directed channel of the frame and a second leg of the finishing member adapted to be juxtaposed to the wall to thereby provide a transition from the frame to the wall;
the finishing member further comprising a terminal end portion and a frangible connection joining the terminal end portion to a remainder of the finishing member;
wherein the terminal end portion is adapted to be removed along the frangible connection and thereby reveal a recess at a juncture adjacent to the frame, the remainder of the finishing member and one of the jambs of the opening.
8. The frame assembly of claim 7 wherein the first and second legs are generally perpendicular to each other.
9. The frame assembly claim 7 wherein the frame is a J-channel frame, the frame assembly further comprising:
one of a window and a door mounted in the frame.
10. The frame assembly of claim 7 wherein the finishing member is a closed cell foam material and the frangible connection comprises perforations in the closed cell foam material.
