Window Type
NCC acoustic doors can be equipped with single-layer or double-layer glasssoundproof perspective windows. The form of acoustic windows can beselected from existing standards (as shown on the left) or made according toorder requirements.
Our Advantages
1.Sound insulation performance: STC31-STC64.
2.Structural forms: single opening, double opening, hinged and sliding.
3.All-metal construction is durable.
4.Standard and custom sizes.
5.Decades of acoustic door production experience.
6.The magnetic sealing strip slowly attracts and closes the door, without a "bang sound, maintaining a quiet environment.
7. Lift the hinge to automatically press the door against the ground, without the needfor sound insulation through the threshold.
8.Each door is assembled in the factory and inspected for verticality, fit, and ease ofoperation before leaving the factory.
9.The separated door frame structure not only adapts to different wall thicknessesbut also is easy and fast to install.
Laboratory Testing
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.
Test Report
NCC sound insulation door designs have been tested in the aeroacoustics laboratory international authoritative laboratories according to international standard.
