Core Product Technology and Features

1. Dual-Core Composite Noise Reduction System

Traditional concealed doors often use hollow, low-density filling structures, which cannot block mid-to-high frequency noise and vibration. KUXIANG innovatively adopts a double-core composite filling structure of bridge-shaped mechanical board and aviation aluminum honeycomb, achieving efficient noise reduction across the entire frequency range.

- Bridge-Shaped Mechanical Board Core Layer: The 45mm thickened door leaf is entirely filled with high-end bridge-shaped mechanical board, drawing inspiration from the geometric pressure-bearing principle of stone arch bridges, resulting in extremely strong impact resistance. The internal dedicated air duct structure effectively absorbs, splits, and reflects airborne noise, significantly reducing sound penetration.

- Aviation-grade aluminum honeycomb reinforcement layer: Built-in precision aluminum honeycomb matrix forms a high-density composite core, effectively isolating various noises such as human voices, television noise, and pipe vibrations, achieving multi-dimensional layered noise reduction while providing a solid and stable feel when the door closes.

2.Intelligent bottom automatic sealing structure

The bottom gap of the door is a major sound leakage point for traditional doors. The Noise Reduction Solid Core Door features a customized spring-loaded automatic lifting and sealing system, completely eliminating leakage problems. A high-density EPDM rubber sealing strip is hidden in the bottom track of the door. When the door is fully closed at 90°, the mechanical anti-collision structure triggers the built-in spring, causing the sealing strip to sink and press firmly against the ground, tightly sealing the gaps and blocking noise, light, dust, and airflow without scratching high-end floors or carpets, achieving multiple protections of quietness, dustproofing, and windproofing.

3. Ultimate architectural invisibility design

- 28mm ultra-narrow visible frame: The extremely narrow visible frame width can be completely hidden in the wall decoration layer, eliminating the abruptness of traditional door frames and providing a clean and tidy visual appearance.

- Flush Inner-Flat Opening Structure: The door panel uses a double-layer 9mm high-density carbon crystal board substrate, ensuring a completely flush fit with the wall and cabinet after installation. This achieves seamless integration of door, wall, and cabinet, providing excellent privacy and significantly enhancing the sophistication and overall aesthetics of the space.

4. High-Strength and Stable Structure

- 2.0mm Aviation-Grade Aluminum Profile: The entire frame is constructed from 6036-T5 aviation-grade pure aluminum with a 2.0mm thick profile wall. This provides extremely high tensile strength and structural rigidity, preventing twisting or deformation even under prolonged high-frequency opening and closing and forceful closure. It can meet the needs of ultra-tall door panel customization.

- High-End Guoxuan Invisible Hardware: Equipped with professional heavy-duty invisible hinges, it supports precise 90° opening and closing, ensuring smooth and seamless operation. It can stably support the weight of the solid door panel, completely eliminating issues such as sagging and uneven gaps, maintaining a tight seal even after long-term use.

5.Full-Dimensional Modular Customization Capability

Adapting to the personalized design needs of high-end projects worldwide, the Noise Reduction Solid Core Door supports full-module customization. Strict adherence to the standard of matching frame and sash colors, combined with a high-definition solid wood grain veneer process, softens the cold feel of metal. Customizable linear grooves, brass decorative lines, and grille designs are available, and the internal filling material can be adjusted according to sound insulation and heat preservation needs, perfectly adapting to various high-end decoration styles.
