Passive fire protection is essential to ensure the safety of people and property in the event of a fire. These protection systems are based on products and materials that help prevent the spread of fire, protect building structures and maintain the integrity of facilities. Below are some of the most common products used in passive fire protection:.
Acoustic absorption mortar: This material combines thermal and acoustic insulating properties with fire resistance. It is used in partitions, ceilings and floors to improve the acoustic performance of spaces and prevent the spread of fire.
Colorless Intumescent Varnish: This is a transparent coating that is applied to wooden surfaces or similar materials. When exposed to high temperatures, this varnish swells and forms an insulating layer that protects the underlying surface from fire.
Liquid membranes: These are water- or solvent-based coatings that are applied in thin layers on different surfaces. When dry, they form a continuous film that acts as a fire barrier and helps prevent the spread of flames.
Intumescent Grilles: They are installed in ventilation openings and air conditioning systems to prevent the spread of fire and smoke. When exposed to heat, intumescent grilles expand and close the passage, maintaining the integrity of the compartment.
Rock Wool Panel: These insulating panels are composed of mineral fibers that offer high fire resistance. They are used in walls, ceilings and floors to improve thermal and acoustic insulation and to protect building structures in the event of fire.
Ablanite Paint: Ablanite paint is a type of coating that comes off in the form of flakes when exposed to high temperatures. This prevents the spread of fire and protects the underlying surface.
Calcium Silicate Panel: These panels are composed of calcium silicate, a fire-resistant and thermal insulating material. They are used in dry construction systems, such as partitions and false ceilings, to improve the fire resistance of structures.
Intumescent Collars: These are devices that are installed around pipes and ducts that pass through fire compartments. When exposed to heat, the collars expand and seal the passage, preventing the spread of fire and smoke.
Rock Wool Mortar: This mortar combines the properties of rock wool with a binder to offer a fire-resistant and thermal and acoustic insulating product. It is used in the construction of fire walls.
Intumescent Paint: Specialized coating that, when exposed to fire, generates a carbonaceous foam and multiplies its thickness to protect steel, wood or concrete structures. In addition to its insulating function, it allows you to maintain a discreet finish in most cases, although its cost is usually higher than that of conventional paints. To guarantee its effectiveness, it is essential to correctly calculate the necessary thickness (according to section, critical temperature and fire resistance) and verify compatibility with the primer and the application environment (interior/exterior, environmental aggressiveness).
Vermiculite Mortar: This mortar is composed of expanded vermiculite, a mineral with insulating and fire-resistant properties. It is used in protection systems for steel structures, as well as in the construction of walls and fire slabs.
Fendolite Cement Mortar: It is a type of refractory mortar composed of cement and special additives that give it thermal insulating properties and fire resistance. It is used to protect metal structures, tunnels and other construction elements exposed to high temperatures.
In summary, passive fire protection is essential to guarantee the safety of people and property in the event of a fire. The products and materials described above are just a few examples of the solutions available on the market. It is important to select and use appropriate and certified products to guarantee the effectiveness of passive protection systems and comply with applicable regulations and standards.
