Specifically designed for spaces with strict sound insulation requirements, such as recording studios, drum rooms, and private cinemas.
G60S

60mm thick professional carbon-plastic composite soundproof door leaf, Two-stage large-D silicone soundproof airtight door frame, Graphene thermal expansion smoke-resistant sealing strip, Servo-driven telescopic carbon-plastic door frame, Flame-retardant soundproof door core, Double-tooth door leaf, Fixed sound barrier, Airtight lock.
Complies with the international E0 environmental standard (zero emissions)
Solid-color water-based paint / Korean PP stain-resistant and scratch-resistant finish
Door Frame Dimensions: H2200 × W900 × D180/448mm (Door opening size +10mm) Door Leaf Dimensions: H2141 × W826 × 50mm
Gross weight ≤ 151 kg (Door panel net weight ≤ 68 kg / Door frame net weight ≤ 55 kg)
STC40dB(±2)
The product's sound insulation rating is based on laboratory test results. Improper installation or sound transmission through the room structure may affect the product's performance.

Airtight Lock System The frame constitutes the core component of any acoustic door structure, where a well-engineered frame design forms the foundation of sound insulation performance. The integration of an airtight lock significantly enhances door sealing integrity. Experimental data confirms that doors equipped with such locks achieve approximately 1-2 dB additional sound insulation improvement. Soundbox prioritizes acoustic excellence over cost considerations, following the selection principles of globally leading acoustic door manufacturers by adopting certified airtight locking mechanisms. Fixed Acoustic Sleeve Assembly Featuring an ultra-low threshold design with dual-layer airtight gaskets, this system effectively eliminates sound leakage through door gaps while improving overall airborne sound insulation performance. The stainless steel-clad threshold combines durable wear resistance with easy-clean maintenance.
