RISE 5/4″ x 8″ x 13' 4″ Trim

RISE trim is a composite exterior trim made from 94% recycled synthetic fibers — polyester, nylon, and fiberglass from post-consumer and post-industrial waste. The key feature is its 13 feet 4 inch length, which matches exactly 10 studs at 16-inch on-center spacing. That’s not random engineering. That’s someone who actually frames houses figuring out how to reduce waste and joints.

The product handles incidental ground contact thanks to its moisture resistance and protective water barrier. In Montana, where spring snowmelt keeps the ground saturated for weeks and freeze-thaw cycles hammer everything touching soil, that ground contact rating matters.

Length Optimization and Installation

At 160 inches long, this trim spans 10 studs at standard 16-inch spacing. Compare that to fiber cement trim that typically comes in 10 to 12-foot lengths — you’re cutting fewer pieces and creating fewer butt joints. Fewer joints means less caulking, less maintenance, and fewer places for moisture to work its way in.

The installation specs tell you this was designed by people who’ve actually installed trim:

Specification	Value
Fastener Type	8d trim nails or 7d trim screws
Penetration	Minimum 1-1/4 inch into framing
Fastener Spacing	16” on-center for studs; 12” on-center for sheathing
Pattern (≤8” width)	2 fasteners
Pattern (>8” width)	3 fasteners
Ground Clearance	4” above landscaping
Deck/Roof Clearance	1/2” above finished surfaces

Temperature affects the gap spacing at butt joints — use 3/16” gap if installing below 60°F, or 1/8” gap at 60°F and above. That’s practical guidance for Montana’s variable temperatures.

Material Performance

The actual thickness is 1.25 inches, giving you substantial material to work with. It cuts with standard woodworking tools — no special blades, no fiber cement dust clouds.

The moisture resistance comes from the synthetic fiber composition. It resists rot, freeze-thaw cycles, heavy rain, and snow. Unlike OSB trim, it offers superior moisture resistance. Compared to fiber cement, it’s easier to cut and handle with less breakage.

The product comes in textured wood-grain or smooth finishes, either factory-finished (ColorRISE) or primed for field painting. The factory finish saves labor. The primed version gives you color flexibility.

Bottom Line

This trim makes sense for Montana contractors dealing with long spans, ground moisture, and freeze-thaw cycles. The 13’4” length optimization alone saves time and reduces failure points. Add the ground contact rating, insect and decay resistance, and workability with standard tools — you’ve got trim that solves real problems.

It’s easier to handle than fiber cement and comes in longer lengths. It beats OSB on moisture performance. And it provides a more natural wood aesthetic than PVC.

The 94% recycled content appeals to green building projects, but that’s secondary to performance. What matters is that this trim handles Montana’s climate without the maintenance headaches of traditional wood trim.

Frequently Asked Questions

Can RISE trim handle direct ground contact?

Yes, it’s rated for incidental ground contact with soil or masonry thanks to its protective water barrier. However, maintain a 4-inch clearance above landscaping for best practice.

What fasteners work with RISE trim?

Use 8d trim nails or 7d trim screws with minimum 1-1/4 inch penetration into framing. Space fasteners at 16 inches on-center when hitting studs, or 12 inches on-center for nailable sheathing.

How does the 13’4” length save money?

The 160-inch length matches exactly 10 studs at 16-inch on-center spacing. This reduces cuts, waste, and the number of butt joints compared to standard 10 or 12-foot trim boards. Fewer joints mean less caulking and fewer potential failure points.

Does temperature affect installation?

Yes. Leave a 3/16” gap at butt joints when installing below 60°F, or 1/8” gap at 60°F and above. This accounts for thermal expansion and contraction.
