RISE Trim 5/4″ x 4″ x 13'4″

RISE Trim 5/4″ x 4″ x 13’4″ is a composite trim board made from 94% post-consumer and post-industrial synthetic fiber waste — polyester, nylon, and fiberglass from recycled carpets, insulation, and wind turbine blades. The 13’4” (160”) length is specifically optimized for 16-inch on-center stud spacing, matching exactly 10 studs. This length advantage over typical 10-12’ fiber cement trim means fewer joints exposed to Montana’s freeze-thaw cycles.

Worth it for contractors who value impact resistance over aesthetics. The composite material has higher resistance to breakage and cracking compared to fiber cement, and it’s rated for incidental ground contact with soil or masonry — useful when trim meets grade at foundation walls or deck posts. Skip it if you’re married to real wood appearance. Even with the texture options, composite is composite.

Material Performance and Installation Reality

The 94% recycled content breaks down to post-consumer and post-industrial synthetic fiber — polyester, nylon, and fiberglass. These fibers come from recycled carpet, vehicle liners, insulation, and wind turbine blades. The environmental angle matters less than the performance benefits: resistance to rot, freeze-thaw cycles, heavy rain, and snow.

Compared to fiber cement, RISE is easier to cut and handle with less breakage. That’s not marketing fluff — fiber cement boards crack if you look at them wrong during transport. The composite material works with standard woodworking tools for cutting, nailing, and screwing. No special blades required.

Installation SpecificationRequirement
Fastener Type8d trim nails or 7d trim screws
Fastener PenetrationMinimum 1-1/4 inch into framing
Fastener Spacing - Studs16 inches on-center
Fastener Spacing - Sheathing12 inches on-center
Fastening Pattern2 fasteners for ≤ 8” width; 3 fasteners for > 8” width
Clearance - Landscaping4” above landscaping
Clearance - Finished Surfaces1/2” above decks/roofs
Butt Joint Gap < 60°F3/16” gap
Butt Joint Gap ≥ 60°F1/8” gap

The temperature-dependent gap requirements matter in Montana. Install in May at 55°F? Use the 3/16” gap. July installation at 85°F? Switch to 1/8”. Get it wrong and you’ll have buckling trim come the next temperature swing.

Length Optimization and Waste Reduction

The 13’4” (160”) length matches exactly 10 studs at 16” on-center spacing. This is longer than typical 10-12’ lengths for fiber cement trim. These longer continuous lengths reduce job-site joints and waste.

Think about it — standard 12-foot boards leave you with awkward 4-foot remnants when spanning standard wall sections. The 13’4” length eliminates most of those cutoffs. Fewer joints also means fewer places for water infiltration during Montana’s freeze-thaw cycles.

Available in both textured (wood-grain) and smooth finishes, with factory-finished (ColorRISE) or primed options. The primed version takes field paint fine, but the factory finish holds up better to UV exposure at elevation.

Applications and Compatibility

Primary applications include exterior trim for corners, window surrounds, and door casing, plus fascia and soffit installations, decorative batten for board-and-batten siding, and areas requiring moisture durability or ground contact.

The trim is compatible with standard 16-inch on-center stud spacing and RISE siding systems including lap, panel, and board-and-batten. Finishing options include field-paintable primed versions or factory-finished ColorRISE.

The product comes with a 30-year limited warranty for the substrate. That’s substrate only — not the finish. Read the fine print before assuming three decades of maintenance-free performance.

Quick Reference FAQ

What makes RISE different from fiber cement trim? RISE uses 94% recycled synthetic fibers versus fiber cement’s portland cement and cellulose composition. Result: easier cutting and handling, less breakage during transport and installation, and longer 13’4” lengths versus typical 10-12’ fiber cement boards.

Can RISE trim touch the ground? Yes, it’s rated for incidental ground contact with soil or masonry. However, maintain 4” clearance above landscaping and 1/2” above finished surfaces like decks or roofs for best practice.

What fasteners work best? Use 8d trim nails or 7d trim screws with minimum 1-1/4 inch penetration into framing. Space fasteners 16” on-center for studs or 12” on-center for nailable sheathing.

How much gap at butt joints? Temperature-dependent: use 3/16” gap if installing below 60°F, or 1/8” gap at 60°F and above. This accounts for thermal expansion and contraction.

Does it really look like wood? Available in textured wood-grain or smooth finishes. It’s composite trim — looks decent painted, but won’t fool anyone expecting clear-stained cedar. Choose it for performance, not aesthetics.

Frequently Asked Questions

Q: What is RISE Trim made from?

RISE Trim is made from 94% recycled post-consumer and post-industrial synthetic fiber waste, specifically polyester, nylon, and fiberglass from recycled carpets, vehicle liners, insulation, and wind turbine blades. The composite material provides resistance to rot, freeze-thaw cycles, heavy rain, and snow.

Q: Can RISE Trim make ground contact?

Yes, RISE Trim is rated for incidental ground contact with soil or masonry, though best practice maintains 4” clearance above landscaping and 1/2” above finished surfaces like decks or roofs. This ground contact rating sets it apart from many wood and fiber cement alternatives.

Q: What’s the actual thickness of RISE 5/4” Trim?

RISE 5/4” Trim has an actual thickness of 1.25 inches (nominal 5/4”), with 8 inches width and 13 feet 4 inches (160 inches) length. The 13’4” length is optimized to match exactly 10 studs at 16-inch on-center spacing.

Q: How do you fasten RISE Trim?

Use 8d trim nails or 7d trim screws with minimum 1-1/4 inch penetration into framing, spaced 16 inches on-center for studs or 12 inches on-center for nailable sheathing. For boards 8” wide or less use 2 fasteners; wider than 8” requires 3 fasteners.

Q: What gap works at butt joints?

Leave a 3/16” gap at butt joints when installing below 60°F, or 1/8” gap when installing at 60°F and above. This temperature-dependent spacing accounts for the composite material’s thermal expansion and contraction.

Q: What warranty does RISE Trim carry?

RISE Trim comes with a 30-year limited warranty for the substrate. Note this covers the substrate material only, not the finish or paint.
