RISE lap siding delivers something most composites can’t touch — ground-contact approved moisture resistance that actually holds up to Montana’s freeze-thaw punishment. Made from 94% recycled synthetic fibers, this isn’t another wood-fiber product that’ll swell when snow sits against the foundation all winter.
The 13’4” length matters more than contractors might think. Standard 12’ siding leaves you with more seams, more caulk joints, more places for moisture to work its way in. RISE’s extended length cuts seam counts by about 25% compared to typical 12’ products. Each board spans perfectly across 16” on-center framing — no awkward joints mid-bay.
Ground-Contact Rated Performance
The ground-contact approval sets RISE apart from every other composite siding option. Most siding manufacturers tell you to keep their product 6-8 inches off grade. RISE doesn’t need that clearance. It handles ground-contact applications where other sidings would rot, delaminate, or fail from moisture wicking.
The synthetic fiber composition — polyester, nylon, and fiberglass — gives it inherent rot-proof properties that engineered wood products can’t match. This material resists rot, decay, and the freeze-thaw cycles that destroy lesser sidings in heavy rain and snow conditions. Spring snowmelt that sits against the foundation for weeks? Not a problem.

Installation Reality
RISE cuts and nails like real wood — no special tools, no silica dust masks, no concrete saw blades. That’s a major advantage over fiber cement, which creates silica dust that requires respiratory protection. Your standard miter saw and finish nailer handle the job.
Installation follows familiar patterns: 1/8” shank roofing nails, minimum 1” penetration into framing, 16” maximum nail spacing. Overlap courses by at least 1 inch, and install over approved water-resistive barrier. Nothing exotic. Nothing that’ll slow down an experienced crew.
The material’s lightweight yet rigid properties reduce jobsite breakage — a real consideration when you’re hauling 13-foot boards up scaffolding. Fiber cement’s weight and brittleness mean more broken boards and wasted material. RISE’s synthetic composition stays intact.
The 94% Recycled Question
The 94% recycled content matters for green building certifications, but what contractors care about is performance. The polyester, nylon, and fiberglass blend creates a stable substrate that won’t move like wood or degrade like some composites.
The fibers come from recycled carpet, vehicle liners, insulation, and wind turbine blades. This mix appeals to builders focused on sustainable practices, but more importantly, it creates a dimensionally stable product that handles Montana’s temperature swings without warping or cracking.

Frequently Asked Questions
Q: How does RISE handle Montana’s freeze-thaw cycles compared to fiber cement?
RISE’s ground-contact approval and resistance to rot, decay, and freeze-thaw cycles make it specifically suitable for heavy moisture conditions. The synthetic fiber composition (polyester, nylon, fiberglass) won’t absorb water like wood-based products. Fiber cement can crack from freeze-thaw if moisture penetrates, while RISE’s synthetic composition remains stable.
Q: What’s the real advantage of 13’4” lengths?
Contractors report the longer lengths reduce seam counts by approximately 25% compared to standard 12’ products. The 13’4” dimension works perfectly with 16” on-center framing, eliminating mid-bay joints. Fewer seams mean less caulking, faster installation, and fewer potential water entry points.
Q: Does RISE require special cutting tools?
No — RISE cuts with standard wood saws and doesn’t create silica dust. Unlike fiber cement which requires dust masks and special blades, RISE works with the saws already on your truck. No respiratory protection needed.
Q: What warranty does RISE offer?
RISE provides a 30-year limited warranty on the substrate, with finish warranties typically running 15 years for ColoRISE colors. CertainTeed backs the warranty.
Q: Can RISE really touch the ground?
Yes — ground-contact approval allows use on low-lying walls and foundation applications. The synthetic fiber makeup inherently resists rot, unlike wood-based engineered sidings that require clearance from grade.
