[Recommendation of ceiling materials for multi-use facilities (schools/hospitals/government offices, etc.)] NF-SDMC Class 1 non-combustible sound absorption metal ceiling material
Hello!👋
It's Zenfix, 'Creative New Value for the Ceiling'.
noise transmitted to people's ears on walls and ceilings
Especially for multi-use facilities such as schools, hospitals, and government offices, the sound absorption environment of indoor spaces is more important.
Also, the safety of the fire is essential because it is a space used by so many people.
High sound absorption performance and fire stability.
Is there a product that meets both of these?
In recognition of its technological prowess, it received 600 million won from the Ministry of SMEs and Startups and jointly developed it with the Industrial-Academic Cooperation Group of Pusan National University.
Non-combustion and high sound absorption performance.
Let me introduce you! For the first time in Korea, NF-SDMC's No. 1 non-combustible sound absorption metal ceiling of ZENFIX !
｜What is sound absorption?
Think of it as literally absorbing sound.
When the noise is reflected against the walls and ceilings of space, It keeps ringing. Sound absorption is to absorb sound so that it does not reflect.
You can check the performance of the building material with the NRC(noise reduction coefficient) sound absorption coefficient.
In order for sound to be absorbed without being reflected, it is the performance of the sound absorber and the perforation of the ceiling surface.
▲SDMC-P40
In the case of the existing sound absorption metal ceiling in Zenpix.
576 suction holes with a diameter of 4mm.
Based on the 600*600-inch ceiling, only 2% of them were pierced to allow sound to be absorbed through.
▲SDMC-P18
The newly developed sound absorption metal ceiling reduced the diameter of the sound absorption perforation to 1.8 mm. Instead, the number was increased to 27,000 and zigzag was closely arranged to increase the ratio of the perforated parts to about 20%.
▲sound passage and reflection according to sound absorption perforation
The sound that passes through the sound absorption perforation is reduced in earnest by the sound absorber attached to the back of the ceiling, so the performance of the sound absorber is very important.
Unlike other Sound absorption Metal Ceiling, which does not guarantee fire stability due to commonly used fiber sound absorbers,
Zenfix has succeeded in developing a sound absorber with a high sound absorption performance and even Non-combustion performance!
｜No. 1 non-combustible
The Ministry of Land, Infrastructure and Transport has divided the flame retardant performance into three grades and announced the criteria for flame retardant performance.
Most of the metal ceiling have semi-combustible performance as a flammable paint layer, but they are vaguely described as non-flammable, so a lot of care is required when selecting the metal ceiling.
▲Non-Flammable Test Report of NF-SDMC
I strongly recommend the reliable Zenfix NF-SDMC Grade 1 non-combustible sound-absorbing ceiling.
