The following tips and features apply to all Trusscore trims.
When cutting trims, tin snips are the safest and easiest tool to use. For a cleaner cut, avoid closing the blades at the end of a stroke.
Leave a minimum of 1/4″ clearance at the ends of all panels and trims to allow for expansion and contraction.
Like Trusscore panels, trims can be fastened to wood, metal, or concrete using readily available screws. Screws should have a minimum head diameter of 3/8″. Install screws for every 2 feet of trim being used.
½” J Trim and ¾” J Trim are perimeter trims meant for the top and bottom of walls, window and door perimeters, inside corners, and SlatWall framing. ½” J Trim is our most popular trim, and it’s pre-punched for easy installation.
Place the longer side of J channel against the wall or ceiling (this is the pre-punched side of ½” J Trim)
Fasten through the holes in the screw flange
For ¾” J Trim, you’ll have to fasten directly through the trim
Insert panels into the channel
For inside corners or wall-to-ceiling transitions, use two J trims:
Install the first J trim following the basic installation method
Place the second J trim against the first with the punched screw flange edge against the wall or ceiling
Fasten through the holes in the screw flange
The channels of each J trim should now be perpendicular to each other to finish your corner
An alternative method uses one J trim instead of two, installed after the panels:
Install panels for one wall or ceiling to the end where you reach the corner
Place the long edge of the J trim against the opposite wall with no panels
Ensure the bottom of the J trim is flat against the panels you just installed
Fasten the trim to the wall with screws through the punched screw flange
The channel on the J trim is now perpendicular to the wall or ceiling with panels
For three-way corner intersections (such as an inside corner meeting the ceiling line), we don’t recommend mitering the J Trims. Simply install the J Trim as mentioned previously and butt each trim piece tightly into the others to finish the corner, or consider incorporating an Inside Cove Corner trim.
For high-moisture applications, before fastening the bottom piece of J Trim to the wall:
Drill 1/4″ diameter holes into the bottom of the J Trim to ensure drainage
Place holes 16″ on-center
For a more complete waterproof seal:
Apply a bead of silicone along the inside of the front-facing edge of any trim pieces before installing the panels, or
Run a bead of silicone after the panels are installed along the seam of the front-facing edge of the trim
H Channel Trim is used for panel joints and product transitions. It’s designed in a convenient two-piece format that snaps together for ease of installation.
Place the U Channel along the end of your panels
Fasten with screws through the pre-punched holes
Continue installing panels on the other side of the U Channel
Leave a 1/4″ gap on both sides of the U Channel to allow for expansion and contraction
When finished installing panels, align the teeth on the H Channel piece with the teeth on the U Channel
Press to snap in to cover any gaps and fasteners
Use Inside Cove Corner trim for inside corners for both wall-to-wall and wall-to-ceiling finishes. A key feature is that it can accommodate two panels, meaning you only need one trim piece to finish inside corners.
Install panels for one wall or ceiling to the end where you reach the corner
Place the long edge of the inside cove corner trim against the opposite wall with no panels
Ensure the other edge of the inside cove corner is flat against the panels you just installed
Fasten the trim to the wall with screws through the screw flange
The channel on the inside cove corner trim is now perpendicular to the wall with panels
Inside cove corner trim can make three-way intersections easier by requiring only one trim piece on the corners instead of two:
Install two J Trim pieces along the ceiling to intersect in the corner (do not miter where they meet)
Install an inside cove corner trim from floor to ceiling to complete the corner
Use Outside Corner Rounded trim on any outside corner of a wall where two Wall&CeilingBoard panels meet to create a rounded corner. This trim piece has two channels on either side of the corner which will accept the two panels meeting to form the outside corner. It should be installed before the panels.
Place the square corner side of the trim against the outside corner of the wall
Fasten with screws on both walls through the screw flange
The channels on the outside corner rounded trim are perpendicular to each other
Insert panels on both walls to finish your corner
Outside corners provide a standard flat outside corner option to neatly complete any wall. Unlike the outside corner rounded trim, this outside corner trim does not have channels to accept panels, so it should be installed after the panels using silicone. Do not use screws when installing this trim.
Install the wall panels to the edge of the outside corner on both walls
Run a bead of silicone on the very edge of the surface of the panel (but not on the tongue or groove) along the entire height or length of both walls
Align the corner of the outside corner trim with the corner of the wall so it is evenly spaced on both sides
Firmly apply pressure where the silicone was applied
Use painter's tape to hold the outside corner trim against the wall while the silicone cures to ensure a strong bond
Use SlatWall Top Cap only when the top of your SlatWall assembly does not directly transition to Trusscore Wall&CeilingBoard. If installing Wall&CeilingBoard above SlatWall panels, use H Channel Snap-In Trim instead of a top cap. Installing SlatWall Top Cap doesn’t require any screws or adhesives.
Place the top lip of the SlatWall Top Cap into the groove built into the top of the uppermost SlatWall panel
Snap the bottom lip of the SlatWall Top Cap into the SlatWall panel
Base trim addresses the transition between wall panels and a concrete floor. It should not be used on sloped floors.
Before installing any panels, place the long straight edge of base trim against the wall with the small corner edge facing the floor
Fasten to the wall with screws through the screw flange
Install panels normally with the bottom edge of each panel extended to the lip of the base trim
Run a bead of silicone along the bottom of the panels for a more finished look and to ensure water does not get behind the panels at the base
F Trim is designed for Trusscore Wall&CeilingBoard applications that include soffit or bulkheads. For RibCore applications, F Trim completes corners.
Place the long edge of the trim against the wall so the channel is at the bottom and facing away from the wall
Fasten to the wall through the screw flange
Place a second F Trim on the opposing wall at the same height as the first F Trim
The channels of each F Trim piece will now be facing each other
Install a Wall&CeilingBoard panel between the two F Trim pieces to complete the installation
The 45° H Channel is a specialized option perfect for instances where two walls or ceilings come together at an angle, including peak ceilings. The 45° H Channel trim has two channels to accept two panels to form the angled corner. It should be installed before the panels.
Place the long edge of the trim piece against the wall or ceiling
Fasten with screws through the screw flange
Insert panels into the opposing channels to finish the angled corner
