RISE lap siding earns attention for two standout features: it’s the only hard siding certified for incidental ground contact, and its moisture resistance handles freeze-thaw cycles better than traditional alternatives. Montana contractors dealing with snow accumulation at foundation level and spring melt conditions finally have a siding that won’t deteriorate where it meets the ground.
The 13’4” length isn’t arbitrary. This 160-inch board spans exactly 10 studs at 16” on-center spacing, reducing seams by 20% compared to standard 12’ boards. Fewer seams mean less water infiltration potential and cleaner sight lines on long walls.
Ground Contact Certification Changes the Game
Traditional fiber cement and wood products fail at the foundation line where snow piles up all winter and moisture lingers during spring thaw. RISE’s ground contact version includes a protective water barrier that prevents moisture wicking into the substrate.
The material consists of 94% recycled content — polyester and nylon fibers from recycled carpet, vehicle liners, and fiberglass from insulation and wind turbine blades. RISE Technology™‘s patented process transforms these synthetic fibers into a composite that outperforms wood, OSB, and fiber cement in moisture resistance.

Installation Beats Fiber Cement
RISE cuts and handles like real wood with no special tools required — standard circular saws work fine, no diamond blades needed. The boards weigh less than fiber cement, reducing crew fatigue on full-house installations.
Standard lap siding fastening applies — typical nail spacing with fasteners placed ¾” from the top edge requiring 1½” minimum penetration. Butt joints must occur over framing studs with 4” flashing behind for water management. Hold siding 3/16” off trim areas and seal with color-matched elastomeric sealant.
The installation requires standard water-resistive barrier and proper flashing, same as any lap siding system. Compatible RISE trim and one-piece corner products complete the system without mixing materials.
Who Should Consider RISE
Contractors working on homes with challenging ground-level moisture conditions benefit most. Properties with poor drainage, high snow accumulation zones, or crawl-space applications where traditional siding fails prematurely make ideal candidates.
The weight advantage over fiber cement matters on multi-story projects where crews haul materials up scaffolding. The 13’4” optimization for 16” stud spacing speeds installation and reduces waste on standard framing.
Budget-conscious builders should note this isn’t bottom-tier pricing. The premium reflects genuine performance advantages — ground contact certification, moisture resistance that handles freeze-thaw cycles, and longer boards than competitors.
Not suitable for vertical applications, fascia, or trim use. Stick to horizontal lap installations where the product engineering applies.
FAQ
What makes RISE different from regular fiber cement siding?
RISE uses 94% recycled synthetic fibers (polyester, nylon, fiberglass) instead of cement and wood fibers. It’s the only hard siding certified for incidental ground contact, and cuts with standard woodworking tools — no diamond blades required.
How does the 13’4” length save money?
The 160-inch length spans exactly 10 studs at 16” on-center spacing, reducing seams by 20% versus standard 12’ boards. Fewer seams mean less labor, fewer butt joints to flash, and reduced waste from cutoffs.
Can RISE siding touch the ground?
Yes — it’s the only hard siding certified for incidental ground contact. The ground contact version includes a protective water barrier to prevent moisture wicking. Standard clearances still apply for proper drainage and ventilation.
What warranty coverage does RISE provide?
RISE includes a 30-Year Substrate Limited Warranty covering the synthetic composite substrate performance and manufacturing defects under specified conditions.
Does RISE require special installation techniques?
No — standard lap siding installation applies. Use typical nail spacing ¾” from top edge with 1½” minimum penetration, install over water-resistive barrier with proper flashing. Maintain 3/16” gap at trim and seal with elastomeric sealant.
