NCP Industries ADORN Stone Ridgestone Series

ADORN Stone Ridgestone is a mortarless stone veneer system that weighs 30% less than traditional stone panels at approximately 13 lbs per panel. The panels measure 23.5 inches long by 6 inches high by 1.75 inches thick, and install with a minimum of 3 screws per panel — no mortar, clips, or starter strips required.

For Montana contractors dealing with wildfire interface zones and freeze-thaw cycles that make mortar unpredictable, this system solves real problems. The Class A fire rating (non-combustible) meets the strictest wildfire codes, while the screw-on attachment works when temperatures drop below mortar’s curing threshold.

Weight Advantage and Installation Reality

At 13 pounds per panel (52 lbs per box), these panels are 30% lighter than traditional stone. That’s not just marketing fluff — it’s the difference between one person handling installation versus needing a crew. Each box contains 4 panels covering 4 square feet.

The installation simplicity beats every clip system on the market. Installation requires coated exterior construction screws or nails with minimum 3/8” heads, at least 1/8” shanks, and 1.5” to 1.75” length. At least one screw must hit a wall stud with 1” minimum penetration. No special clips. No proprietary fasteners. Just screws you already have on the truck.

Surface prep involves standard house wrap or weather-resistant barrier (WRB), with optional 15-lb black felt wrap for added protection. The system works over wood framing with OSB/sheathing, ICF, brick, stucco, and foam-board insulation. That substrate compatibility matters when you’re retrofitting existing buildings or working over ICF foundations common in energy-efficient Montana builds.

Fire Performance and Environmental Technology

The Class A non-combustible rating puts this product in the same category as fiber cement for wildfire resistance. ADORN meets ASTM C1670 (Standard Specification for Adhered Manufactured Stone Veneer Units) and has been tested for wind load and fire safety.

The panels use high-strength concrete blended with recycled materials and proprietary CaptureCrete® technology — a CO2-absorbing binder. This technology actively absorbs CO2 during manufacturing, with each square foot capturing approximately 1.5 lbs of CO2. The product contributes to LEED points for builders chasing green certifications.

Specification	Value
Panel Dimensions	23.5” x 6” x 1.75”
Weight per Panel	Approx. 13 lbs
Coverage per Box	4 sq ft (4 panels)
Fire Rating	Class A (Non-combustible)
CO2 Absorption	1.5 lbs per sq ft
Minimum Fasteners	3 screws per panel

No plastic or foam content means these panels won’t melt or off-gas in fire conditions — a real consideration for WUI construction.

Installation Tools and Accessories

Required tools include a drill or impact driver, saw with concrete/masonry blade, level, and tape measure. Standard contractor kit. No specialized equipment rental.

The system is compatible with ADORN series corners, sills, and column kits. Available accessories include Ridgestone Corners (boxes of 12), Sills (boxes of 3), Pillar Stones (boxes of 4), and Post Stones (boxes of 12). Having a complete accessory system matters — nothing worse than beautiful field panels meeting amateur-hour corners.

For existing stucco applications, ADORN recommends painting the stucco black for aesthetic consistency — the dark backing helps maintain shadow lines between stones.

Warranty and Limitations

The product comes with a Limited Lifetime warranty covering manufacturing defects only, non-transferable to subsequent owners. Exclusions include structural movement or settling, chemical contact or painting, staining/oxidation, efflorescence, and labor costs for removal or replacement.

That’s a standard manufactured stone warranty — protects against the product falling apart, not against installation errors or building movement. The non-transferable aspect might matter for spec builders planning quick flips.

Bottom Line

ADORN Ridgestone works for Montana contractors who need fire-resistant cladding that installs in unpredictable weather. The 30% weight reduction and mortarless system cut labor time when you’re racing weather windows. Class A fire rating satisfies WUI requirements without the weight penalty of traditional masonry.

Skip it if you’re after the deepest shadow lines — at 1.75 inches thick, these panels won’t match the depth of full-thickness stone. The CO2-absorbing technology is interesting but won’t swing most bid decisions. What matters is that these panels go up fast, meet fire codes, and don’t require perfect mortar weather.

Works for interior and exterior use, but the real value shows on exterior applications where fire rating and weather resistance justify the material cost. The product is ICC-ES compliant with AC51 for manufactured stone veneer — that certification smooths permitting in jurisdictions that care about such things.
