The exterior doors and windows of the building are the structural members of the building. As an important part of the building, the exterior doors and windows of the building should have the necessary energy-saving, ventilation, wind pressure resistance, airtightness, watertightness, lighting, etc. At the same time, it also requires certain comfort and safety and durability.For a time, the building door and window industry is full of sound. The revision of a building code has caused a wave of waves in the industry.
What is the difference between fire-resistant building doors and windows and fire doors and windows? How do ordinary building doors and windows meet the requirements for fire integrity? What is the impact of fire integrity on other properties of building doors and windows? How to check the fire-resistant building doors and windows project? A series of problems came one after another. Today, the fire window system discusses the difference between fire resistant building doors and windows and fire doors and windows.
Building exterior doors and windows with fire-resistant integrity, many people think that there is no fire doors and windows that do not have thermal insulation requirements, this is completely incorrect understanding.
First of all, the main functions of the two are different. Non-insulated fire doors and windows focus on its fire protection function, and its physical properties require little or no requirements. Fireproof windows require only air tightness and wind pressure resistance, while fire doors are not required. Building exterior doors and windows with fire integrity should first ensure their physical and mechanical properties, such as suitability and energy efficiency, while fire integrity is one of the many safety requirements for building doors and windows.
Second, the main materials of the two are different. Although fire-resistant glass is required, fire-resistant doors and windows usually use steel profiles with high melting points as the frame, which results in poor energy-saving performance and is not suitable for use as exterior doors and windows. The exterior doors and windows of the building generally use materials with good energy-saving effects such as heat-dissipating aluminum alloy profiles and PVC-lined steels. However, these profiles cannot be used for fire doors and windows because of their low melting point.
Moreover, the two methods of opening and closing control are different. In addition to the normal opening and closing operation, the fire-proof window with opening function requires an additional sash opening and closing control device to meet the automatic closing function under fire conditions; the fire door is usually equipped with a fire door closer or an automatic door closing device. The outer window of the building only needs to be installed with a manually operated hardware opening and closing device, and it is not necessary to have the function of automatically closing the door and window fan under fire conditions.
It can be seen that even if the exterior doors and windows of the building need to have fire-resistant integrity requirements, they should not be treated as non-insulated fire doors and windows, but should be classified as non-fire-fighting products. The design ideas, testing techniques and acceptance methods of the fire integrity performance indicators should be coordinated with other physical and mechanical performance indicators that the building doors and windows should have.
