Fire resistant door seal

Types of fire resistant door seal

A fire-resistant door seal is a critical component designed to enhance the safety and effectiveness of fire-resistant doors. These seals come in various types, each serving unique purposes. Below are the common types of fire door seals:

• Intumescent Seals:

  Intumescent seals are one of the most popular fire door seals. They are commonly installed in the frame of the door. Intumescent seals are made of materials like graphite and ammonium phosphate. When exposed to high temperatures, these materials expand significantly. The seals can expand up to 100 times their original size during a fire. This sealing off any gap between the door and the frame. The expanded seal helps to stop the movement of smoke and fire, preventing their spread to other building areas.

• Rubber Seals:

  Rubber seals are another commonly used fire door seal. They are usually used as a smoke seal. Rubber seals are made from intumescent material. They create a barrier to prevent smoke from passing through the gaps in the fire door. It's important to note that while rubber seals can be effective at stopping smoke, they may not provide the same level of fire resistance as intumescent seals.

• Metal Seals:

  Metal seals are mostly used in high-security areas. They offer a durable and robust sealing solution for fire doors. These seals are designed to withstand the rigors of frequent use and provide long-lasting performance. While metal seals may not expand like intumescent seals during a fire, they create a strong barrier that can help prevent the passage of fire.

• Compression Seals:

  Compression seals are versatile sealing solutions that can be used for fire doors and regular doors. These seals are designed to be compressed between the door and the frame when the door is closed. They effectively block out smoke, fire, and sound while also preventing the intrusion of dust and pests. Compression seals are ideal for areas where a tight seal is crucial.

• Drop Seals:

  Drop seals are a unique type of fire door seal. They are installed at the bottom of the door. These seals remain retracted when the door is open. However, they automatically lower to seal the gap when the door is closed. Drop seals provide an effective barrier against smoke and fire while allowing for easy access.
