NCP Industries ADORN Stone Ledgestone Series Corner Pieces

NCP Industries’ ADORN Stone Ledgestone corner pieces offer a mortarless, fastener-only installation system that’ll cut your corner installation time in half compared to traditional mortared stone. Each box contains 6 sets (12 interlocking pieces) covering 3 vertical linear feet — enough to handle a typical 8-foot corner with two boxes.

The standout feature? CaptureCrete® technology that absorbs and neutralizes CO2, making this one of the few building materials that actually reduces atmospheric carbon while it sits on your wall. Skip it if you’re looking for budget vinyl corners. This system targets contractors who need the look of stacked stone without the mortar mess, drying time, or callbacks from freeze-thaw failure.

Technical Specifications and Coverage

Each corner set consists of 2-piece interlocking units measuring 6 inches tall with alternating lengths of 5.5 and 9.5 inches, at 1.75 inches depth. The interlocking design eliminates the need for mitered cuts or special corner treatments.

Specification	Value
Height	6 inches
Interlocking lengths	5.5” x 9.5”
Depth	1.75 inches
Coverage per box	3 vertical linear feet
Pieces per box	6 sets (12 pieces total)
Weight per box	Approx. 50 lbs
Material	High-strength recycled materials

The coverage math works out simply — 3 vertical feet per box means you’ll need 3 boxes for a standard 8-foot corner with a bit left over. At 50 pounds per box, one person can handle the material without equipment.

Installation Requirements and Montana Considerations

The system requires only 2 fasteners per corner unit — that’s it. No mortar mixing, no adhesive cure time, no weather delays waiting for mortar to set. You’ll need exterior-coated screws or nails with minimum 3/8 inch head diameter and 1/8 inch shank, penetrating at least 1 inch into studs.

The substrate requirements stay straightforward: 7/16 inch OSB or plywood sheathing firmly attached to wood or metal studs, with a two-layer weather barrier — standard house wrap plus 15 lb felt or Grade D building paper.

Montana installations demand attention to one critical detail: The product is designed for natural movement and requires 2-inch clearance from hard surfaces. This isn’t optional. Montana’s freeze-thaw cycles — 100+ per year in most valleys — will heave any masonry product that’s locked against pavement or concrete. That 2-inch gap lets the material move without cracking.

CaptureCrete® Technology and Environmental Impact

The CaptureCrete® technology absorbs and neutralizes CO2, turning a typically carbon-intensive product into a carbon sink. Made from high-strength recycled materials, the product qualifies for LEED credits.

The environmental angle isn’t just marketing fluff. Each square foot captures 1.5 lbs of CO2, which means a typical residential corner installation permanently removes about 30-40 pounds of CO2 from the atmosphere. The technology actively captures and permanently stores CO2 throughout the product’s life.

FAQ

What tools are needed for installation? You’ll need a drill/driver, level, cutting tools (snips, chop saw, circular saw, or diamond-blade grinder), plus standard eye, hearing, and dust protection.

How does this compare to traditional mortared stone corners? The mortarless, fastener-only dry-stack system eliminates mortar mixing, application, and cure time. You’re looking at 50% faster installation with no weather delays for mortar drying.

Is this compatible with other ADORN products? Yes, it’s fully compatible with ADORN Ledgestone Series Flats, Pillars, and Posts, allowing you to create complete stone veneer systems.

What about the warranty? Limited lifetime warranty covering defects in materials when installed per local codes and manufacturer instructions. Non-transferable to subsequent owners. Excludes settling, chemical damage, fastener corrosion, and labor costs.

Can this be installed directly on concrete or masonry? The system works on concrete substrates, though you’ll still need appropriate fasteners for concrete attachment and the same 2-inch clearance from grade.
