more than one decade of experience in the design and manufacturing of soundproof doors. NCC has installed more
than 5,000 soundproof doors which can be widely used in various places and for various purposes, with Rw values up to Rw69. All soundproof doors have passed air-acoustic laboratory testing.
The application scenarios of NCC noise cancelling Doors include:
hospitals, hotels, schools, shopping malls,
theaters, offices, broadcast studios, nightclubs, museums,
Different places such as test rooms, laboratories, factories, printing plants and power plants.
In fact, they can be used anywhere sound needs to be kept inside or outside a building/room.
Dimension & Appearance
NCC acoustic door, which is renowned for its excellent soundproofing performance, can be classified into two main
types based on the opening mechanism: the single - door and the double - door.
All doors are equipped with connecting locks, latches and handles (samples available or customized upon request)
The sound insulation door can be equipped with bird and insect screens as required
Doors can be coated with polyester powder coating
It can be galvanized steel, stainless steel, or aluminum
The door kit includes door panels, detachable door frames, sealing strips, decorative accessories and glass (according to customer requirements), so the acoustic performance of these soundproof doors can fully meet the values calibrated in the promotional materials, and they can be installed quickly and conveniently on site. NCC attaches great importance to quality control, and the company has passed ISO9001 quality certification and three environmental system certifications.
Sound insulation performance: STC31-STC64.
Structural forms: single opening, double opening, hinged and sliding.
All-metal construction is durable.
Standard and custom sizes.
Decades of acoustic door production experience.
The magnetic sealing strip slowly attracts and closes the door, without a "bang" sound, maintaining a quiet environment.
Lift the hinge to automatically press the door against the ground, without the need for sound insulation through the threshold.
Each door is assembled in the factory and inspected for verticality, fit, and ease of operation before leaving the factory.
The separated door frame structure not only adapts to different wall thicknesses but also is easy and fast to install.
NCC's anechoic louver has an energy-efficient aerodynamic design and a very low pressure drop characteristic. The sturdy all metal structure ensures a long service life for NCC's noise reduction louvers. If necessary, we can also provide necessary supporting steel structures and provide comprehensive installation services.
NCC Acoustic Laboratory - A Laboratory Professionaly Committed to Serving Customers
We exert every ounce of our strength to construct a high-end, avant-garde laboratory endowed with autonomous control capabilities. For all bespoke products, be it in terms of specifications, dimensions, or acoustic requisites, prior to entering the mass production phase, we shall enforce rigorous and meticulous pre-production sample testing procedures. Only upon thorough confirmation that all indicators are up to par will we invest a considerable amount of human and material resources to embark on mass production endeavors, thereby effectively guaranteeing that each and every batch of large-scale goods delivered to clients possesses outstanding quality.
The fabricated product samples are positioned within the spacious window of the laboratory and securely fastened through professional sealing measures. Through precise adjustment of the relevant parameters and concurrent utilization of advanced and precise apparatuses for comprehensive and profound testing, it is ultimately ensured that the products can fully comply with the exacting requirements of customers.
As depicted in the illustration, the external noise of the laboratory attains 80.1 dB, while through random measurement, the internal acoustic laboratory drops to 36.4 dB or even lower. The elevated standard of sound insulation not only ensures the accuracy of the experimentation but also furnishes a robust guarantee for the test outcomes.
All Reports can meet the American Standars, the sound testing we did with Intertek
