Fire Doors Materials
Steel
Steel is the most flame-resistant material. Heavy-duty steel sheets and airtight seals make steel doors the superior option when it comes to resisting heat. However, steel is usually the most expensive option and not necessarily the most aesthetically pleasing.
Timber
It may be surprising, but there is a large range of wooden fireproof doors on the market. The timber is treated with a fire-resistant sealant to achieve a protective barrier. Wooden-based doors are more affordable than steel and usually look more attractive.
Glass compounds
Glass or ceramic glass reinforced with steel or other metals to increase its flame resistance is also used for fireproofing. Glass can also work well with the building’s interior design as it helps create a lighter, brighter space.
Application of Fire Doors
A smoke control door is purpose-built to contain smoke within specific areas so that it doesn’t overwhelm people exiting stairwells and other evacuation routes. A smoke door has some fire-resistant properties but usually won’t contain flames for an extended period.
An acoustic fire door combines fire resistance with sound insulation capabilities. These doors are commonly used in theatres, conference facilities, recording studios, and properties located in noisy environments.
Door frame: The frame is the structure into which the door is installed. It provides support, and stability, and helps maintain the fire integrity of the system.
Door leaf: The leaf is the main block or panel of the door. The thickness and composition of the leaf determine its fireproof rating.
Seals: Seals are an essential component of fire doors as they help restrict the passage of smoke and flames. Intumescent strips are usually used as seals. They are made of materials that expand when exposed to heat, creating a barrier that fills gaps between the door leaf and frame. A silicon-based resistant sealant may be used to ensure the leaf and frame fit flush.
See-through panels: Fire doors may also incorporate other features like vision panels made from heat-resistant glazing.
Hardware: Fire doors typically include a closing mechanism. This is a spring-loaded or hydraulic mechanism that forces the door closed in an emergency. The system also includes hardware like hinges, locks, latches, handles, and closers.
