In the United States, hotel soundproof doors must meet the requirements of fire, flame retardant and sound insulation at the same time, which are enforced by NFPA, IBC and UL standards, and the sound insulation and fireproof performance go hand in hand.
Core regulations and standards
NFPA 101Life Safety Code: the fire rating of the guest room door is 20m / 45min, and the corridor / stairwell door is 60m / 90min to ensure the safety of the evacuation path.
NFPA 80 “Fire door Standard”: standardize the installation, maintenance and annual inspection of fire doors to ensure continuous effectiveness.
IBC “International Building Code”: define the fire protection rating of doors on the evacuation path and control the spread of fireworks.
UL certification: according to the UL 10B/10C test, the UL label can be complied with to enter the market.
Typical rating and sound insulation requirements
Common fire rating: the room door is usually used for 20pm for 45 minutes, and the corridor / staircase is commonly used for 60pm for 90min (according to building height and use).
Sound insulation requirements: refer to ASTM E90, room door sound insulation is usually ≥ STC 30, high-end hotels may require STC 35 +.
Key points of compliance: fire doors need to be marked with UL tags, door sealers, seals, locks and other accessories must match the door body grade; sound insulation should be realized through door seam sealing, double stops, special sound insulation materials, etc., which is compatible with fireproof structure.
Key points of compliance process
- The fire grade and sound insulation index are determined according to the building type and floor.
two。 Buy finished door with UL certification label, matching level of accessories.
- After installation, do annual inspection and maintenance according to NFPA 80 and keep records.
List of technical parameters for procurement of soundproof fire doors in American standard hotels
Applicable scenarios: middle and high-end hotel room doors, corridor doors, staircase doors
Core compliance standards: NFPA 101, NFPA 80, IBC, UL 10B/10C, ASTM E90
I. Fire performance parameters
- Fire rating:
Guest room door: 20 shock 45 minutes (UL certification, meet the NFPA 101s room evacuation door requirements)
Corridor / staircase door: 60pm 90 minutes (IBC for high-rise building evacuation passageway requirements)
two。 Certification requirements: door body and all accessories (door closures, hinges, seals) should be marked with UL 10B/10C certification label, fire rating, production batches
- Fire integrity: no penetrating cracks occur within 0.5h (20 minutes) / 1.5h (90 minutes) in a fire
- Fireproof seal: adopt fire expansion seal, expansion ratio ≥ 300%, in accordance with UL 1784 standard
Second, sound insulation performance parameters
- Sound insulation grade: STC 35 + (refer to ASTM E90 test standard, meet the sound insulation requirements of high-end hotel rooms; basic model can be reduced to STC 30)
two。 Construction requirements:
Door leaf: double-layer fireproof board + high density sound insulation core (such as rock wool / glass wool, density ≥ 120kg/m ³)
Door seam treatment: double sealing structure (around the door leaf + threshold), using rubber sound insulation sealing strip, compression ratio 15% Rue 20%
Door frame: the joint with the wall is filled with sound insulation mortar to avoid sound bridge transmission.
III. Material and structural parameters
- Door leaf material:
Panel: cold-rolled steel plate (thickness ≥ 0.8mm) or fireproof solid wood composite board (additional flame retardant treatment is required, in accordance with NFPA 255)
Core material: flame retardant and soundproof rock wool / glass wool, non-flammable grade A
two。 Door frame material: galvanized steel (thickness ≥ 1.2mm), anti-corrosion treatment, suitable for hotel humid environment
- Dimensional tolerance: door leaf dimension deviation ≤ ±2mm, flatness deviation ≤ 1mm/m
Technical requirements for accessories
- Door closer: UL certified, matching door body weight (60-120kg), door closing speed adjustable, conforming to ANSI/BHMA A156.4 standard
two。 Hinge: stainless steel, load-bearing ≥ 80kg/ pair, at least 3 pairs per door, with antirust coating
- Lock: fireproof anti-theft lock, with emergency escape function (room can be opened with one button), in accordance with ANSI/BHMA A156.13 standard
- Threshold: stainless steel, height 5-8mm, with non-slip lines, closely fit with door seal
Installation and acceptance requirements
- Installation specification: strictly follow the installation requirements of Chapter 5 of NFPA 80, the gap between the door frame and the wall is filled with fireproof and sound insulation mortar
two。 Acceptance criteria:
Fire test: third-party organizations conduct fire resistance test according to UL 10B and provide test report
Sound insulation test: according to ASTM E90 field test, STC value is up to the standard
Annual inspection requirements: annual maintenance inspection according to NFPA 80 standard, keep inspection record
