Invisible Flush Wooden Doors

Invisible Flush Wooden Doors are interior doors with concealed frames, MDF/HDF skins, LVL structure and customizable finishes. They reduce visible door-frame lines, helping maintain a clean, continuous wall appearance in residential, hotel and commercial interiors.

Outer Surface: Finished with a professional-grade, high-quality primer, fully compatible with standard interior wall paints and coatings.

Facing: High-density MDF/HDF layers ensuring a stable, warp-resistant substrate for final surface treatments.

Frame/Stile: Precision-engineered LVL (Laminated Veneer Lumber) core offering superior structural rigidity and load-bearing capacity.

Core Options: Engineered core alternatives selected for optimal acoustic attenuation and long-term dimensional stability.

Hardware Integration: Equipped with heavy-duty, 3D-adjustable concealed hinge systems for smooth, seamless operation.

Visual Continuity: The completely flush design preserves the clean line of the wall, making it the ideal solution for minimalist aesthetics, hidden storage entries, or secret rooms.

Structural Integration: Specialized aluminum frame profiles anchor firmly to wall studs, facilitating a clean, crack-free drywall finish.

Space Versatility: Highly adaptable to diverse site conditions, supporting standard drywall and masonry wall types.

Project Precision: Each unit is custom-manufactured strictly according to your project's door schedule to guarantee consistent margins and reliable, long-term performance.

Oversized & Custom Dimensions: Heights up to 2800 mm, with reinforced LVL construction and anti-warp tensioners for improved stability.

Opening Configurations: Flexible in-swing and out-swing options available.

Advanced Hardware Integration: Precise CNC machining pre-configured for your specified lock-sets, handles, and electronic access/smart lock systems.

Collaborative Engineering: Our technical team reviews CAD files and door schedules to verify structural fit before production begins.

Subfloor & Leveling Requirements: Surrounding wall structures must be completely plumb and level (Recommended Drywall Finish: Level 4 or 5) prior to frame installation to maintain the precision 2 mm operational gap.

Finished Floor Height: Finished floor levels must be specified at the time of order; standard door leaf clearances are calculated based on your exact flooring material thickness.

Technical Submittals: Every order includes detailed technical data sheets and shop drawings. Production commences only after formal client sign-off on these dimensions.

Strict QC Standards: 100% inspection throughout raw material selection, core assembly, CNC machining, and pre-packaging.
International Standards: Manufactured to meet strict environmental and durability standards, with ISO9001 and FSC certifications supporting sustainable building requirements.
Acoustic & Fire Resistance Performance: Acoustic Attenuation: Engineered for high-performance sound isolation, achieving STC 32–35 dB (tested per ASTM E413 / ISO 717-1 standards).

Fire Performance: 30-minute fire-rated configuration backed by CPR directive certification (CE compliance). Official test reports and documentation are available for project submittals.
