What is a fire -resistant wall?
Fire resistant wall is a structure designed to slow down the spread of heat, smoke and flames during an emergency. Properly constructed firewall gates give passengers more time to safely leave the building during a fire and can help reduce total property damage. By slowing down or preventing the spread of fire, these walls give firefighters more time to save the building and its content or for rescuers.
It is important to understand that a fire -resistant wall is not designed to be completely fire resistant. Instead, each fire wall is given a specific evaluation based on the time to prevent fire from spreading. In buildings that are located very close to each other, the outer resistant wall of the fire may have a three -hour rating, which means that it can prevent the spread of fire for up to three hours. Some inner walls may only have a 20 -minute assessment, depending on the risk of fire, the number of exits and the load on the structure.
Many cities require a fireplace of wall -mounted wall walls as the sameST local building regulations and standards. In the US, fire -related codes are often based on standards developed by the National Fire Protection Association (NFPA). NFPA and similar organizations determine how the fire walls should be designed, tested and maintained to last against high temperatures, smoke and flames. The duration of the fire evaluation is often based on the types of materials used in the building or on the functions carried out in the equipment.
concrete or masonry can be built a fire -resistant wall because these materials offer natural resistance to fire. In order to build a fire wall of plasterboard, the builders must include special plastering products resistant to fire designed to slow down the spread of flames or heat. Gypscart assesses assesses assesses as evaluated can also be used as cladding to protect unfinished walls or insulation in unoccupied areasTech buildings. When the steel included in a fire -resistant wall, it can be sprayed with a cement coating designed to help the metal hold against high temperatures.
During a wall -resistant wall construction, all components used to build a wall must include a suitable fire assessment. For example, any window, door or glass included in the wall must be fire resistant. These objects are usually made of special materials to ensure the correct level of fire resistance. All pipes or pipes that penetrate from the wall must have the same fire assessment and to seal all cracks, gaps and holes around these intersections must be used special seals.
