Dubuild Panel
1 / 5
Our acoustic barriers, centered on professional acoustic technology, provide effective noise reduction solutions for transportation, industrial, and architectural sectors. Constructed with high-strength metal frames and composite soundproof panels, combined with precision manufacturing processes, they significantly reduce various noises such as vehicle roars and mechanical vibrations, achieving full-frequency noise attenuation. The products adhere strictly to international standard production processes, ensuring stable performance in complex environments.
Model: NB-50
Thickness: 50mm
Hole type: Micropore
Noise reduction: Sound insulation ≥ 30 dB
Filling material: Glass fiber wool (48kg/m3)
Finish: Polyester Powder Coating (PPC)
Our Acoustic Barrier Panels are specifically designed to provide customized noise control solutions for generator rooms. Crafted with precision-perforated designs and high-strength galvanized steel, these panels deliver a significant noise reduction of over 30 dB, effectively isolating mechanical operational noise while withstanding long-term use in harsh environments.
