Engineered for High-Traffic Durability: Structural Stability and Waterproof Performance

The structural integrity of our wood glass doors is predicated on a hybrid engineered core, not solid timber. This eliminates the inherent weaknesses of natural wood—warping, splitting, and dimensional instability under thermal and moisture loads. The core is a cross-laminated LVL (Laminated Veneer Lumber) frame, providing a torsional stiffness rating exceeding 3200 Nm², which ensures permanent alignment of hardware and glass under repeated use. This frame is encapsulated within a high-density Wood Plastic Composite (WPC) cladding, formulated to a minimum density of 1.35 g/cm³ and a PVC-to-wood flour ratio optimized for surface hardness and impact resistance.

Functional Advantages of the Engineered System:

• Zero Hydroscopic Warping: The WPC cladding has a moisture absorption rate of <0.5% (per ASTM D570), and the sealed LVL core is stabilized to ≤8% moisture content. This renders the door assembly impervious to humidity cycling, making it suitable for direct entry and high-moisture interior applications.
• Impact-Resistant Surfaces: The composite material achieves a Shore D hardness of 75-80, resisting denting from incidental impact common in commercial, hospitality, and multi-family residential settings.
• Integrated Thermal Break & Acoustics: The multi-material construction creates a discontinuous thermal bridge, achieving a U-factor of ≤1.2 W/(m²·K). The mass and damping effect of the composite layers provide a sound reduction rating (Rw) of 28-32 dB.
• Inherent Fire Performance: Core and cladding components are independently tested to relevant reaction-to-fire standards (e.g., EN 13501-1, Class C-s2,d0 / ASTM E84, Class B), contributing to compartmentalization without requiring chemical impregnation.

Performance Specifications:
| Parameter | Test Standard | Performance Value | Implication |
| :— | :— | :— | :— |
| Dimensional Stability (Swelling) | ISO 16983 | ≤0.8% over 24h immersion | Guarantees consistent operation and fit; no sticking in frames. |
| Formaldehyde Emission | EN 16516 / JIS A 1460 | E0 Grade (≤0.05 ppm) | Meets stringent indoor air quality standards for all environments. |
| Cycle Testing (Durability) | ANSI/BHMA A156.13 | >200,000 cycles (Grade 1) | Exceeds commercial-grade requirements for high-traffic doorways. |
| Surface Scratch Resistance | EN 438-2:2016 | Class 3 (high resistance) | Maintains aesthetic integrity against abrasion from cleaning and use. |

All manufacturing processes are governed under an ISO 9001:2015 certified quality management system, ensuring batch-to-batch consistency essential for large-scale projects. The system’s stability allows for the integration of full-length glass panels up to 10mm thick without risk of frame distortion, supported by a structural silicone glazing or compression gasket system engineered for long-term weatherproofing.

Enhance Indoor Air Quality: Formaldehyde-Free Construction for Safe Environments

Formaldehyde emissions from traditional composite wood products are a primary contributor to indoor air pollution, linked to long-term occupant health risks. Our wholesale wood glass doors are engineered to eliminate this concern at the source through advanced, formaldehyde-free material systems and stringent manufacturing controls.

Core Material Science & Compliance
The structural integrity and air quality safety are achieved through precise material formulation and third-party verified standards.

• Composite Core: We utilize high-density Wood Plastic Composite (WPC) or laminated veneer lumber (LVL) cores. The WPC is engineered with a proprietary PVC-to-wood flour ratio, resulting in a density exceeding 750 kg/m³. This creates an inert, stable substrate that requires no formaldehyde-based resins for bonding.
• Adhesives & Finishes: All laminates, edge banding, and coatings are applied using isocyanate (MDI/PURI) or polyurethane-based adhesives and UV-cured acrylic finishes, which are inherently formaldehyde-free.
• Certification Standards: All core and panel materials consistently meet or exceed the strictest international emission standards:
  • CARB Phase 2 & TSCA Title VI (USA): Certified for ultra-low emitting formaldehyde.
  • EN 717-1 (Europe): Class E1 (≤ 0.1 ppm) and available in E0 (≤ 0.05 ppm) specifications.
  • F★★★★ (Japan): The most stringent grade, verifying formaldehyde emissions below 0.03 mg/L.
• Quality Assurance: Our ISO 9001:2015 certified manufacturing process includes batch testing via the ASTM E1333 or EN 717-1 chamber method to ensure consistent, verifiable performance.

Architectural & Performance Advantages
Formaldehyde-free construction does not compromise performance; it enhances it by utilizing higher-grade, more stable materials.

• Superior Dimensional Stability: The low moisture absorption rate (<8% per 24h, ASTM D570) of the WPC core and the cross-laminated LVL structure minimize swelling and warping, ensuring long-term fit and operation.
• Enhanced Indoor Environmental Quality (IEQ): Beyond formaldehyde-free, the non-porous surface and sealed edges inhibit mold growth and allergen accumulation, contributing to a healthier indoor environment.
• Integrated Performance: The stability of the core material directly supports the door’s overall acoustic and thermal performance by maintaining consistent seals. The inert core also contributes to a higher fire resistance rating, typically achieving Class B/s2-d0 per EN 13501-1.
