Buy good quality Door Seals at low price Wedge India. Door Seals are crucial components in fire and smoke protection systems, designed to prevent the spread of fire, smoke, and sound through gaps around doors. These seals ensure that fire-rated doors maintain their integrity during a fire, providing a barrier that protects occupants and property.
Types of Door Seals
Intumescent Seals:
- Function: Expand when exposed to high temperatures, sealing gaps and preventing the passage of fire and smoke.
- Common Uses: Around the edges of fire-rated doors.
Acoustic Seals:
- Function: Provide soundproofing as well as fire and smoke resistance.
- Common Uses: Doors in sound-sensitive areas like conference rooms, recording studios, and hospitals.
Smoke Seals:
- Function: Prevent the passage of smoke and toxic gases, often combined with intumescent seals.
- Common Uses: Doors in corridors, stairwells, and other escape routes.
Threshold Seals:
- Function: Seal the gap between the bottom of the door and the floor, preventing drafts, fire, and smoke penetration.
- Common Uses: All types of doors, especially fire-rated doors.
Weather Seals:
- Function: Provide a barrier against external elements like rain, wind, and dust, in addition to fire and smoke.
- Common Uses: Exterior doors.
Key Properties of Door Seals
Thermal Expansion: Intumescent seals expand significantly when exposed to heat, sealing gaps and providing a barrier to fire and smoke.
Adhesion: Strong adhesion to door and frame materials, ensuring a secure and continuous seal.
Flexibility: Ability to accommodate door movement and vibrations without compromising the seal.
Durability: Long-lasting performance under normal conditions and during a fire.
Compliance: Suitable for use with a wide range of door materials, including wood, steel, and composite doors.
Applications of Door Seals
Fire-Rated Doors:
- Intumescent seals around the edges of fire-rated doors expand during a fire to seal gaps between the door and frame, preventing fire spread.
Smoke Control Doors:
- Smoke seals prevent smoke from passing through gaps around doors, maintaining clear escape routes during a fire.
Acoustic Doors:
- Acoustic seals reduce noise transmission while also providing fire and smoke protection.
Exterior Doors:
- Weather seals combined with fire and smoke seals provide comprehensive protection against external elements and fire hazards.
Installation Guidelines
Surface Preparation:
- Ensure surfaces are clean, dry, and free of dust, grease, and other contaminants before applying door seals.
Proper Sizing:
- Select door seals of the correct size and type for the specific door and gap width.
Application Method:
- Follow manufacturer instructions for the application of door seals, ensuring they are properly positioned and adhered.
Regular Maintenance:
- Inspect door seals regularly for damage or wear, and replace them as necessary to maintain their effectiveness.
Compliance:
- Ensure all door seals and installations comply with relevant building codes and fire safety standards.
