A quantified core platform for three interior applications: ultra-tall doors, dry partition walls, and dry double-floor assemblies. Read each system’s performance against its complete build-up and the reported specimen.
Tested in a dry double-floor system at ΔLH(II)-3S / ΔLL(II)-3S, suppressing low-frequency footsteps and high-frequency impact noise.
GBRC appendix reference measurement with an 80 mm diameter circular pressure plate: 0–0.1 mm residual displacement after unloading and no damage to the complete floor specimen.
Continuous curves radiate point loads in all directions — a material-usage comparison at equal stiffness.
The China CTC report states not detected (<0.10 mg/L); the Japan GBRC result is below the quantification limit (<0.1 mg/L).
Note: 60% is a company material-usage comparison. The 100 kg figure is an appendix reference measurement for the complete raised-floor specimen in the GBRC report, not a universal load rating for the core alone.
Anova Core™ is not a finished panel. It is a core platform for door makers, joinery factories, and system integrators. Every benefit must be mapped back to the correct specimen and full assembly.
GBRC tested | 100 kg · ≤1.7 mm
GBRC appendix reference measurements of the complete double-floor system: 100 kg localized load, 0.8–1.7 mm immediate displacement and 0–0.1 mm residual displacement, with no specimen damage. Tesla footage illustrates curved-core load distribution, not certified load capacity. Arched topology supports tall-door stability design; moisture-related deformation requires validation of the faces, edges, and complete door.
CTC tested | Rw 30 dB airborne sound
CTC measured Rw 30(-2;-3) dB airborne sound insulation for a 52 mm single-core specimen. Once the complete wall is verified against the project acoustic target, additional rock-wool filling may be omitted following assessment, simplifying installation. Core results do not establish finished-door or wall performance.
Two reports | Below reporting limits
China CTC reports formaldehyde not detected (<0.10 mg/L); Japan GBRC reports a result below the quantification limit (<0.1 mg/L). These results do not mean absolute zero formaldehyde. No E0 or F☆☆☆☆ mark has been applied for or obtained.
The same platform core answers different questions through different complete assemblies and standards. Four evidence axes are kept separate instead of being reduced to one marketing number.
GB/T 19889.3-2005; 52 mm single-core specimen, Rw 30(-2;-3) dB.
JIS A 1440-1/-2; the 173.5 mm double-floor assembly achieved (II)-3S for both sources.
Reference measurement with an 80 mm diameter circular pressure plate: immediate deflection of 0.8–1.7 mm at 100 kg, no specimen damage.
Japan: <0.1 mg/L (below the quantification limit) / China: <0.10 mg/L (not detected).
GBRC Japan used JIS A 1440 standard light and heavy impact sources to test a dry raised acoustic floor on anti-vibration mounts at a 173.5 mm finished-floor height.
Represents higher-frequency chair movement, dropped objects, and surface tapping.
Represents lower-frequency footsteps, running, jumping, and thudding impacts.
Values are in dB. “—” means the report provides no value for that band; no zeros have been inserted. At 4 kHz, the light-source value with the specimen is ≤17 dB, so no reduction index is stated.

An 80 mm diameter circular pressure plate was incrementally loaded at points S1–S4. The report defines this as an appendix reference measurement, not a product load rating.
General | ΔLL-2 / ΔLH-1–2
Mainstream | ΔLL-3 / ΔLH-2
High performance | Reference band ΔLL-3–4 / ΔLH-3; this specimen’s formal grades are ΔLL(II)-3S / ΔLH(II)-3S.
Added damping | ΔLL-5 / ΔLH-4
Reference: sound-insulation evaluation standards commonly used in Japan’s raised-floor market; this comparison is not a formal rating issued by the individual GBRC report.
Sound enters the composite panel structure.
Continuous curves redirect the wave path.
Internal fiber friction dissipates energy.
Less vibration and sound transmitted to the other side.
From core to finish, build a fabricable, engineerable, and testable assembly for ultra-tall concealed doors, sliding doors, and interior partitions.
Move beyond common 2.4 m door planning dimensions toward 4–5 m concealed and sliding-door designs. Continuous-curved load paths support dimensional-stability design; final dimensions, bending performance, and durability require whole-door engineering and validation.
The New Taipei workshop demonstrates framing, roller gluing, core fitting, and cold pressing. No dedicated core-processing line is required; production on existing equipment depends on press capacity, adhesive selection, and process qualification.
Integrate magnetic airtight edge strips and concealed hinges for cushioned contact, quieter closing, and door sealing. Timber frames or engineered reinforcement carry screw fixings and concentrated loads; verify screw retention, operating durability, and airtightness in the complete door set.
Plan thin-stone, metal-sheet, or thick-veneer finishes. Balanced build-ups, weight distribution, and controlled bonding address sagging and warping risks; verify adhesion, creep, and hardware capacity for each assembly rather than assuming unconditional sag resistance.
The New Taipei workshop demonstrates integration with existing timber-door production: frame forming, two-sided roller gluing, core fitting, and cold pressing. The aim is rapid production adoption using existing equipment; confirm press capacity, adhesive, pressure, and curing time before production.
Process 01
Build the frame around door dimensions, hardware, and edge requirements.
Process 02
Set glue coverage for the selected face board and adhesive before pressing.
Process 03
Cut and arrange the core so the continuous topology covers the working area.
Process 04
The image shows preparation beneath the “cold-press bonding” station; actual pressure, time, and adhesive conditions are set by the fabricator.
4 m door leaves were exhibited at the 2026 Taiwan International Interior Design Expo (TIDE) and ARCHITECTURE + CONSTRUCTION MATERIALS 2026 (The 32nd), Tokyo, March 3 (Tue.)–6 (Fri.), 2026. Continuous arched topology distributes concentrated loads along curved surfaces. These are exhibition showcases; complete doors still require frame and hardware engineering.
CTC report WT2023B03A01247: Rw 30(-2;-3) dB. Finished door or partition performance depends on face boards, edge treatment, frame, and hardware seals; the final rating requires testing of the fabricator’s complete product.

Playlist: Tesla drive-over → sandbag impact test. Use the tabs to switch at any time. Both videos are visual demonstrations, not certified load or impact ratings.
The Tesla drive-over and sandbag-impact videos visualize the continuous-curved load path. Both are demonstrations only. Engineering decisions must rely on the GBRC appendix reference measurement for a 100 kg localized load and project-specific structural calculations; any impact rating for a finished door requires separate testing.
For rental-property operators, developers, panel fabricators, and interior designers: dry modular assembly and demountable joints enable flexible reconfiguration. Natural-fiber composite panels can form a lightweight partition strategy; calculate reductions in floor dead load from the complete wall’s mass per square metre relative to the original design.
Use core-and-face assemblies to avoid unnecessary solid material in partition design. Calculate actual weight savings from frames, face boards, fixings, and the complete wall; no universal reduction percentage is assumed.
The CTC 52 mm single-core specimen achieved Rw 30(-2;-3) dB, providing a starting point for material selection. Joints, perimeter seals, openings, and penetrations affect the complete wall’s performance; the core value is not a finished-wall rating.
Prefabricate timber frames, panels, and demountable joints for on-site assembly. Plan disassembly and reuse around the actual connections, reducing wet-trade waiting and supporting rental, exhibition, and interior-layout changes.
The three-layer sandwich logic separates material responsibilities: Anova Core™ supplies the continuous-curved core, while the fabricator selects face boards, bonding, and finish.
17.5, 25, or 35 mm continuous-curved natural-fiber core forming the structural and acoustic intermediate layer.
Project-selected MDF, PB, OSB, plywood, or other confirmed board materials.
Paint, veneer, laminate, textile, or another interior finish selected for the design and fabrication process.
Dimensions and thicknesses are planning points. Supply, cutting, and finished thickness remain subject to face-board and project conditions.
52 mm is the total thickness of the single-core CTC airborne-sound specimen. Other thicknesses are common planning combinations and do not inherit the same acoustic result.

Anova Core™ is a natural-fiber core for fabricators, not a certified complete door set. The fabricator specifies face boards, frame, edge treatment, and hardware.
No. CTC WT2023B03A01247 reports Rw 30(-2;-3) dB for the 52 mm single-core specimen. A complete door set requires separate acoustic testing.
No. CTC WT2023B01A05265 reports <0.10 mg/L, not detected; GBRC VD-26-0012 reports <0.1 mg/L, below the quantification limit. No E0 or F☆☆☆☆ mark has been applied for or obtained.
For 4–5 m door designs, engineer symmetrical face layers, timber framing, and hardware capacity together. Control moisture, edge sealing, adhesive, and cold-press conditions. The arched core provides load paths but does not guarantee warp-free performance in every build-up; validate the complete door.
The specimen in signed GBRC report IVA-26-0082E had a finished height of 173.5 mm, with light-impact ΔLL(Ⅱ)-3S and heavy-impact ΔLH(Ⅱ)-3S results. These apply to the tested complete floor, supports, and finish, not directly to a bare core or a different build-up.
Existing frame-forming, two-sided roller-gluing, core-fitting, cold-pressing, and veneering processes can be considered. Confirm press dimensions, balanced face layers, adhesive, pressure, and curing time, then validate bonding and dimensional stability in a trial run. Equipment changes may still be required.
Four questions—from use to surface treatment—let ArchiNova and the fabricator quickly frame core thickness, face boards, samples, and the testing path.
Door leaf, partition, dry raised acoustic floor system, overhead panel, or worktop.
Maximum length and width, target thickness, and project quantity.
Acoustics, localized load, material health, or regulatory conditions.
Face board, finish, edge treatment, hardware, and installation interfaces.
