RISE 3/8” lap siding lets you install right to the ground — the only hard siding with that capability. The 13’ 4” length fits 16” O.C. studs exactly, cutting down on joints and waste. Made from 94% recycled content including polyester, nylon, and fiberglass sourced from recycled carpets, vehicle liners, and wind turbine blades.
Skip it if you’re looking for budget siding. This is engineered composite targeting durability and specific performance advantages, not the cheapest square foot coverage.
Ground Contact and Environmental Resistance
The ground contact versions include a protective water barrier, making this the only hard siding that allows incidental ground contact. That’s a game-changer for installations where siding meets grade — decks, patios, landscaping transitions. No more rot concerns at the bottom course.
The material resists rot and damage from temperature fluctuations, handling freeze-thaw cycles that destroy lesser sidings. Montana sees 100+ freeze-thaw cycles annually in most valleys. This matters.
The recycled content isn’t just marketing fluff. The siding contains 94% recycled polyester, nylon, and fiberglass from industrial waste streams — recycled carpets, automotive vehicle liners, insulation manufacturing, and wind turbine blades. That’s legitimate diversion from landfills, not token percentages.
Installation Specifications and Requirements
The boards come in 3/8” thickness, 8.25” width, with 13’ 4” (160”) length. 7-inch exposure when installed. That length isn’t arbitrary — 13’ 4” fits 16” O.C. studs exactly, reducing joints.
| Specification | Value |
|---|---|
| Thickness | 3/8 inch |
| Width | 8.25 inches |
| Length | 13 feet 4 inches (160 inches) |
| Exposure | 7 inches |
| Stud Spacing | 16 inches max |
| Fasteners | 6d hot-dipped galvanized nails |
| Overlap | 1 to 1.25 inches |
| Joint Treatment | 4-inch wide flashing required |
Installation requires 6d hot-dipped galvanized nails — not just any nail will do. Joints need 4-inch wide flashing, and maintain 1 to 1.25 inch overlap. Follow these specs or void the warranty.
Available in PPG Duracolor machine-applied paint with smooth or woodgrain textures. Color-matched touch-up kits and ASTM C920 elastomeric sealant available.
Warranty and Certifications
30-year limited warranty on the substrate, 15-year finish warranty. That’s confidence in freeze-thaw performance and UV resistance at elevation.
ICC-ES ESR-4731 certification, meets CALGreen 2025 standards, and Florida Building Code 2020. The ICC-ES report matters — third-party verification of performance claims.
Marketed as more durable than fiber cement, easier to handle, with longer boards. Provides similar appearance to wood but with moisture and rot resistance.
RISE fills a specific niche — when you need ground contact capability, exceptional recycled content, or those 13’ 4” lengths that eliminate joints on 16” centers. The technology works. Whether it’s worth the premium depends on your specific installation challenges.
Frequently Asked Questions
Q: Can RISE 3/8” lap siding really touch the ground without rotting?
Yes, RISE siding with ground contact versions includes a protective water barrier, making it the only hard siding that allows incidental ground contact. The 94% recycled polyester, nylon, and fiberglass composite resists rot and moisture damage, eliminating the typical concerns when siding meets grade at decks, patios, or landscaping transitions.
Q: What’s actually in RISE siding that makes it 94% recycled?
RISE 3/8” lap siding contains 94% recycled content from industrial waste streams: polyester and nylon fibers from recycled carpets and automotive vehicle liners, plus fiberglass from insulation manufacturing and wind turbine blades. This synthetic fiber composite provides durability while diverting legitimate volumes from landfills.
Q: Why are RISE boards 13’ 4” long instead of standard lengths?
The 13’ 4” (160”) length fits 16” O.C. studs exactly, eliminating a joint every 10 feet compared to standard 10-foot boards. This reduces seams, cuts installation time, and minimizes waste on typical framing.
Q: What special installation requirements does RISE siding have?
RISE 3/8” lap siding requires 6d hot-dipped galvanized nails (not standard nails), 4-inch wide flashing at all joints, and 1 to 1.25 inch overlap between boards. Maximum stud spacing is 16 inches, and the siding provides a 7-inch exposure when properly installed.
Q: How does RISE compare to fiber cement siding for freeze-thaw resistance?
RISE siding is marketed as more durable than fiber cement with better freeze-thaw resistance due to its synthetic fiber composition. The 30-year substrate warranty and 15-year finish warranty back up its performance claims in temperature cycling conditions.
Q: What finish options come on RISE factory-finished siding?
RISE ColoRISE factory-finished siding features PPG Duracolor machine-applied paint in smooth or woodgrain textures. Color-matched touch-up kits and ASTM C920 elastomeric sealant are available for field repairs and joint sealing.
