Fire doors are a crucial component of a building's passive fire protection strategy. They are utilized for fire compartmentation, a method that establishes physical barriers in key locations throughout a building to impede the propagation of flames and smoke during a fire incident.
Fire doors may be constructed from a combination of timber, steel, gypsum, and aluminum. They may also feature windows constructed from borosilicate or ceramic glass, both of which provide superior fire protection compared to normal glass, and may incorporate an anti-shattering wire mesh.
To improve their fire-stopping efficacy, fire doors are aligned with the frame; any openings are sealed with silicone-based fire-resistant sealant. These are frequently complemented by an intumescent strip affixed to the base of the door, which swells upon exposure to heat to inhibit smoke infiltration beneath.
Fire doors are typically equipped with a closing mechanism. Typically installed in the upper section of a door, these spring-loaded or hydraulic devices compel the door to close, inhibiting the transmission of fire and smoke between distinct areas.
It is important to note that although numerous doors may include some or all of these characteristics, they may not inherently qualify as 'fire doors.' A design must be certified by a manufacturer to be designated as a 'fire door.' Fire door certification is granted after a door successfully undergoes many evaluations at an accredited facility, encompassing fire and stress simulations.
If you seek to ensure your building, whether residential or commercial, complies with current fireproofing regulations, please contact us. We guarantee complete adherence to the most recent standards.
We specialise in the protection of buildings from fire by the insulation of structural members, walls and tanks against direct attack from flames by maintaining load-bearing members and tank-shells below the critical point at which failure or weakening is likely to occur.
