Fire performance
The core of fire protection is the "fire resistance limit", which is the ability to prevent the penetration of flames and high temperatures within a certain period of time.
Function: In case of fire, it blocks the spread of fire, buys time for escape and rescue, and prevents the maintenance opening from becoming a "chimney".
Key indicators: Fire resistance limit (such as Class A 1.5 hours, Class B 1.0 hours, Class C 0.5 hours).
Implementation method: Use non-combustible materials (such as galvanized steel plates, gypsum boards, aluminum alloys) to fill fireproof rock wool, expansion sealing strips, etc.
Applicable locations: It is mandatory to be used in public areas such as fire pipe wells, strong and weak electric wells, smoke exhaust machine rooms, and fire partition partition walls.
Sound insulation performance
The core of sound insulation is "sound insulation volume", that is, the ability to reduce sound penetration, the unit is decibel (dB).
Function: Reduce the impact of the sound of running water in pipes and noise from the next room on life, and improve privacy and comfort.
Key indicators: Sound insulation index (such as 30dB to 55dB), the higher the value, the better the sound insulation.
Implementation method: Increase surface density (use heavy materials) and sealing (use sealing strips and magnetic strips to eliminate gaps).
Applicable locations: Bedrooms, study rooms, video rooms, bathrooms and other spaces that require quietness.
