CertainTeed RISE Trim brings 94% recycled content to the trim market — polyester, nylon, and fiberglass from post-consumer waste including recycled carpets and wind turbine blades. Boards come in 13’4” lengths optimized for 16” on-center framing (matches 10 studs), reducing joints on those long Montana ranch-style runs.
The material resists rot, freeze-thaw cycles, heavy rain, and snow, which covers pretty much everything Montana throws at exterior trim.
Installation Specs That Matter
RISE requires specific fastening: 8d trim nails or 7d trim screws with minimum 1-1/4” penetration into framing. Temperature matters for gap spacing — 3/16” gap if installing below 60°F, 1/8” gap at 60°F or above for butt joints. That’s smart thermal engineering for Montana’s temperature swings.
| Specification | Value | Source |
|---|
| Length | 13 feet 4 inches (160 inches) | manufacturer |
| Recycled content | 94% | manufacturer |
| Fastener spacing | 16” on-center for studs; 12” on-center for nailable sheathing | manufacturer |
| Fasteners per board | 2 fasteners for ≤ 8” width; 3 fasteners for > 8” width | manufacturer |
| Ground clearance | 4” above landscaping; 1/2” above finished surfaces | manufacturer |
Available in textured (wood-grain) or smooth finish, either factory-finished (ColorRISE) or primed. The primed version lets you match existing colors — practical when you’re patching into an existing paint scheme.
RISE works with standard woodworking tools — no special blades, no toxic dust clouds like fiber cement creates. It’s lightweight for easier handling and has high resistance to breakage and cracking compared to fiber cement. Anyone who’s watched a 12-foot fiber cement board snap during installation knows that matters.
RISE products resist moisture, freeze-thaw cycles, and rot. The dual water protection barrier on both sides keeps moisture from penetrating the substrate. That’s different from one-sided protection where the back face becomes the weak point.
The Trade-Off Reality
Compared to wood trim, RISE offers more durability, rot-proof performance, and lower maintenance. Versus fiber cement, it’s easier to cut and handle with less breakage, plus those longer 13’4” lengths versus typical 10-12’ boards. The extra length alone saves labor on long runs.
The 94% recycled content matters if you’re chasing green building points or just want to reduce landfill contribution. But let’s be honest — durability drives the decision, not environmental awards. The material includes recycled polyester, nylon, and fiberglass that would otherwise hit the dump. Health Product Declaration (HPD) and Safety Data Sheet (SDS) are available for projects requiring documentation.
The 30-year limited warranty covers the substrate — standard for the composite trim category. Real-world performance in freeze-thaw cycles will tell the story.
Skip RISE if you’re trimming a shed or doing a quick flip where longevity doesn’t matter. Pressure-treated lumber costs less upfront. But for quality builds where callbacks eat profits, the moisture resistance and dimensional stability earn their keep. That 13’4” length optimized for 16” on-center framing shows somebody actually thought about how trim gets installed.
FAQ
How does CertainTeed RISE handle Montana’s freeze-thaw cycles?
RISE is specifically rated as resistant to freeze-thaw cycles. The dual water protection barrier on both sides prevents moisture infiltration that causes freeze damage in other materials. The 94% synthetic fiber content (polyester, nylon, fiberglass) doesn’t absorb water like wood or fiber cement.
What fasteners work with CertainTeed RISE trim?
Use 8d trim nails or 7d trim screws with minimum 1-1/4” penetration into framing. Space fasteners at 16” on-center for studs or 12” on-center for nailable sheathing. Use 2 fasteners for boards 8” or less in width, 3 fasteners for wider boards.
Can CertainTeed RISE trim touch the ground?
Maintain 4” clearance above landscaping and 1/2” above finished surfaces like decks or roofs for proper drainage and ventilation.
Does CertainTeed RISE trim require special tools?
No — RISE works with standard woodworking tools for cutting, nailing, and screwing. It’s described as lightweight for easier handling and has less breakage than fiber cement. No special blades or dust protection required like with fiber cement products.
