External fire doors are an essential component in ensuring the safety and protection of a building, offering numerous benefits that extend beyond their primary function of fire containment. These doors are specifically designed to withstand extreme heat and prevent the spread of fire, smoke and toxic gases from one area to another.
Their fire-resistance rating indicates the duration they can withstand direct exposure to flames without compromising their integrity. This rating is determined through rigorous testing and certification processes, ensuring compliance with local building codes and safety regulations. Depending on the application and risk assessment, fire doors can be rated for varying periods, ranging from 30 minutes to several hours.
In addition to their fire-resistant properties, external fire doors are engineered to be robust and durable. They are typically constructed with reinforced steel or solid timber cores, encased in fire-resistant materials such as gypsum or mineral wool. The door frames and hardware are also designed to withstand high temperatures and prevent warping or deformation.
