Single Leaf Fire Doors

Standard Dimensions for Single Leaf Fire Doors

The selection and installation of Single Leaf Fire Doors are crucial components of fire and smoke protection systems, especially in corridors, stairwells, indoor public areas, and rooms with combustible surfaces. Fire doors come in various types, such as vertically opening doors, horizontally rolling doors, double-leaf doors, sliding doors, and the same-type doors. Depending on the specific construction environment, it’s essential to check the building structure and surrounding space before installation.

For typical buildings, the standard dimensions for a single-leaf fire door are as follows:

• Door Height: Typically 2150mm (can vary based on design requirements)
• Door Width: 1200mm
• Double-Leaf Fire Door Width: 2400mm
• Rolling Fire Door Width: Common widths include 1200mm, 1400mm, 1500mm, and 1800mm

Single Leaf Fire Doors Frame Dimensions

Different types of fire doors have corresponding door frame sizes:

• Vertical Fire Doors: Frame width is generally 1350mm, and height is typically 2000mm
• Rolling Fire Doors: Same frame dimensions as vertical fire doors
• Double-Leaf Fire Doors: Frame width of 1350mm and height of 2000mm
• Sliding Fire Doors: Similar dimensions to other types, with frame width generally around 1350mm and height at 2000mm

Installation Requirements

Installation guidelines also vary depending on the door type:

• Vertical Fire Doors: Recommended to be installed on railings with enough base and bracket support for stability.
• Horizontally Rolling Fire Doors: Should have fasteners at both ends of the brackets to limit frame movement.
• Double-Leaf Fire Doors: The thin surface should be positioned higher for optimal fire resistance, with brackets made of steel or aluminum to secure both ends and the closure.
• Sliding Fire Doors: Similar to horizontally rolling doors, typically mounted with steel fasteners to the wall.

Single Leaf Fire Doors Clearance and Insulation

For safe operation and maintenance, fire doors generally require a 15cm clearance on both sides, ensuring proper ventilation and easy access for servicing. Above the fire door track and around metal or insulated fire doors, a 50mm insulation pad is necessary to reduce heat transfer through the top of the frame.

Soundproof and Thermal Insulating Fire Doors: Soundproof Performance

Overview

Soundproof and thermal insulating fire doors are designed to provide not only fire protection but also effective sound insulation. This dual functionality is essential in various applications, especially in commercial and residential buildings where noise control is important.

Soundproof Performance

1. Material Composition:
   • These doors are typically constructed with specialized core materials that enhance sound insulation. Common materials include mineral core, honeycomb core, or acoustic foam, which help absorb sound waves and reduce noise transmission.
2. Design Features:
   • The door design often includes weatherstripping and seals around the edges to minimize sound leakage. These features help create a tight fit when the door is closed, further enhancing its soundproofing capabilities.
3. STC Rating:
   • The sound transmission class (STC) rating measures a door’s soundproofing effectiveness. Higher STC ratings indicate better sound insulation. Soundproof and thermal insulating fire doors typically have STC ratings ranging from 30 to 50, depending on the design and materials used.
4. Application Scenarios:
   • Commercial Buildings: Used in offices, conference rooms, and hotels where noise control is essential for privacy and comfort.
   • Residential Settings: Ideal for apartment complexes, separating living spaces to reduce noise from common areas or adjacent units.
   • Specialty Facilities: Employed in recording studios, theaters, and medical facilities where sound isolation is critical.
5. Fire Safety:
   • In addition to their soundproofing features, these doors maintain fire-resistant properties, helping to prevent the spread of flames and smoke in the event of a fire, ensuring compliance with safety regulations.

Conclusion

Soundproof and thermal insulating fire doors are a valuable investment for environments where both fire safety and noise control are priorities. Their effective soundproofing capabilities, coupled with fire resistance, make them suitable for various applications, enhancing overall comfort and safety in any building.
