The performance of fire doors not only depends on the quality of the product itself, but also is closely related to the installation process. The following are common misunderstandings and correct installation specifications in the industry.
Myth 1: The gap between the door frame and the wall is not sealed or properly sealed. In order to save time, some installation teams only fill the gaps with cement mortar and do not use special fireproof sealants, which are easy to spread from the gaps during fire, reducing the fire prevention effect. The correct approach is that after the door frame is installed and fixed, the gap needs to be filled with fireproof sealant or fireproof mud to ensure that it is tight and porous.
Myth 2: The selection of hardware accessories does not match. Fire doors need to be equipped with special fireproof hinges, locks, door closers and other accessories, and some projects use ordinary civil hardware to reduce costs, resulting in inflexible opening and closing of the door body and substandard fire resistance. For example, Class A fire doors need to be equipped with large load-bearing hinges that can withstand high temperatures, and door closers need to have an automatic closing function to ensure that the door body closes automatically in the event of a fire. All fire doors in the pilot door industry are equipped with original fire hardware to avoid affecting the overall performance due to accessory problems.
Myth 3: The door body opens in the wrong direction. The opening direction of the fire door should be in the direction of evacuation, that is, "open out", and some projects will be changed to open inward due to space restrictions, and the evacuation of personnel in the event of a fire may be delayed by the door body blocking. During installation, it is necessary to clarify the opening direction of the door body according to the building fire protection design drawings to ensure that the evacuation channel is not affected.
Myth 4: No opening and closing debugging. After installation, the door body is not tested for opening and closing flexibility and whether the door closer is moderately forced, which may lead to the door body not being able to close completely or opening difficultly. The correct process is to repeatedly test the door body opening and closing after the installation is completed, adjust the door closer force, and ensure that the door body can automatically close and lock without external force, and the gap is uniform.
In addition, the installation team needs to have professional qualifications, and cross-border projects need to cooperate with local construction specifications, such as Russian projects need to pay attention to low-temperature resistance debugging of door bodies, and Southeast Asian projects need to be moisture-proof. Pilot Door Industry provides installation guidance videos and technical support to assist customers in avoiding installation misunderstandings and ensuring that products successfully pass the fire inspection.
