DecoGroove delivers authentic wood-grain aesthetics on any facade without the maintenance obligation that fiber cement demands from day one. Built on a co-extruded WPC platform with a polymer cap permanently bonded to a recycled hardwood fiber core — no repainting, no resealing, no remediation cycles over a building’s lifetime.
Wholesale & trade pricing available. Custom sizes, colours, and packaging on request.
ABOUT THIS PRODUCT
The alternative to fiber cement shouldn’t come with a maintenance schedule attached. DecoGroove composite siding is built on a co-extruded WPC platform — recycled hardwood fiber core, HDPE matrix, and a permanently bonded polymer cap — that replaces the paint layer fiber cement relies on with a surface that doesn’t crack, chalk, or require recoating at any point in its service life.
For wholesale distributors stocking exterior products, this translates directly to fewer contractor callbacks, stronger sell-through on commercial accounts, and a product that closes on total installed value — not just the line-item unit price. For general contractors managing multi-story or mixed-use facades, it removes an entire trade from the punch list on day one.
0.8 mm
Cap Layer Thickness
Thicker than most competing composite wall panel products on the U.S. market — the board's permanent defense against UV oxidation, moisture ingress, and the micro-cracking that begins the deterioration cycle in painted systems
ΔE ≤ 4–5
Color Shift · 3,000 hrs QUV
Benchmarked against sustained UV index levels common across Florida, Texas, Arizona, and Southern California — where standard paint-based finishes fade within five years of installation
26.2 MPa
Flexural Strength · EN 15534
Supports multi-story residential, mixed-use, and Type III and Type V commercial construction where wall panel deflection and load performance are part of the specification review
0.2%
Water Absorption · ASTM D1037
Eliminates the swelling, mold colonization, and joint failure that fiber cement experiences at unsealed field cuts — a chronic failure point in humid coastal and Gulf Coast climates

Product Detail
Unlike coated composite boards or painted fiber cement, DecoGroove is co-extruded — the protective polymer cap is molecularly fused to the structural core during the manufacturing process, not applied as a post-production coating. This is the fundamental distinction between a surface that can peel and one that cannot. The 0.8 mm cap layer is stabilized with a dual-system UV package combining Hindered Amine Light Stabilizers (HALS) with UV absorbers, achieving a documented color shift of ΔE ≤ 4–5 after 3,000 hours of QUV accelerated weathering exposure.
The composite core contains zero exposed cellulose. In termite-active states — including Florida, Louisiana, Texas, Georgia, and Hawaii, where subterranean termite pressure makes untreated wood-based materials a long-term liability — this structural design removes the infestation risk entirely. There is no cellulose pathway for colonies to exploit, regardless of how the board is cut or fastened in the field.
At 0.2% water absorption under ASTM D1037 testing, the closed-cell HDPE matrix performs as a sealed system at cut edges, fastener penetrations, and board joints. In the high-humidity conditions of the Gulf Coast and Pacific Northwest — where fiber cement regularly absorbs moisture at unsealed cuts and develops mold at joints within the first maintenance cycle — this is the performance gap that drives the specification switch to composite cladding.
LastElegance DecoGroove composite siding products are tested against internationally recognized performance standards. Full third-party test reports are provided to distributors and specifiers on request to support commercial project sign-off and AHJ review.

LastElegance OEM and ODM manufacturing services are structured for distributors and commercial builders who need product differentiation at the regional or national account level. Customization scope includes board dimensions, surface texture and emboss depth, color development from RAL or Pantone reference, packaging and branding design, and profile geometry — with custom tooling available for proprietary profile shapes.
Supply programs are designed for regional building material chains managing multiple distribution points, commercial contractors with consistent facade volume across project pipelines, and national wholesalers transitioning from branded import sourcing to factory-direct relationships. Contact the LastElegance trade team for container pricing, current lead times, and minimum order thresholds by program type.
Colour Range
All colours are co-extruded into the board surface — not painted — ensuring consistent colour and finish across the full facade for the life of the product. Custom colour matching is available for volume orders.
MATERIAL COMPARISON
Fiber cement dominates the U.S. exterior wall market — and for good reason. But every specification comes with a cost that doesn’t appear on the initial bid: mandatory priming and painting on installation, then again every 7 to 10 years. For commercial owners, HOA communities, and multifamily developers, that recurring maintenance liability compounds across a building’s lifetime.
DecoGroove delivers equivalent facade durability at a total lifecycle cost that changes the procurement conversation.
DecoGroove exterior wall panels are manufactured and tested to internationally recognized standards, including CE, ISO, RoHS, and SGS certifications. Performance testing includes ASTM D1037 (water absorption) and EN 15534 (flexural strength). For projects requiring IBC compliance documentation or state-specific approval, our trade team provides complete third-party test reports to support the specification and Authority Having Jurisdiction (AHJ) review process.
Current fire performance test data is available from our trade team on request. For projects in California, Colorado, or other Wildland-Urban Interface (WUI) designated zones, we recommend confirming product suitability with your local building department and fire authority using our available documentation prior to specification. Our team can assist in preparing the submission package.
Yes. DecoGroove installs over a standard aluminum or treated timber subframe with a ventilated cavity, consistent with rainscreen cladding assemblies. The concealed clip fastening system eliminates face-fix fasteners and produces a flush, uninterrupted facade surface. The installation workflow is familiar to commercial framing and facade crews working with standard rainscreen and panel systems.
Material cost per unit is typically higher for composite wall cladding. However, the installed cost gap narrows significantly when field labor is accounted for — DecoGroove is lighter, faster to handle on multi-story projects, and requires no field priming or painting on installation day. Over a 15-year building lifecycle, eliminating two to three full repainting cycles is the figure that drives the procurement decision for most commercial developers and property managers we supply.
Yes. The 26.2 MPa flexural strength (EN 15534) and 0.2% water absorption (ASTM D1037) are consistent with commercial facade and mid-rise specifications. LastElegance supplies directly to commercial general contractors and wholesale distributors servicing Type III and Type V construction across North America. Project-specific technical documentation and test reports are available to support specification review.
None beyond routine cleaning. The co-extruded polymer cap layer requires no painting, staining, oiling, or sealing at installation or at any point during the product’s service life. For facades in high-traffic urban environments or direct coastal salt exposure, periodic washing with water and a mild detergent is sufficient to maintain the panel’s appearance.
Eight standard wood-tone finishes are available for standard order. Distributors and commercial builders requiring regional exclusivity or private-label branding can access full OEM color development from RAL or Pantone reference — including custom packaging, labeling, and product naming. Custom color programs are structured at qualifying volume thresholds. Contact the LastElegance wholesale team for program details.
Yes. OEM and ODM programs cover board length, width, profile geometry, emboss texture, grade specification, and packaging design. Custom tooling for proprietary profile shapes is available for qualifying order volumes. Lead times and minimums vary by customization scope — contact our trade team to outline your distribution program requirements.
