What are the features of fireproof aluminum alloy Windows and how to choose them?
It is a safety awareness that each of us should possess to be vigilant in times of peace and prevent problems before they occur. Fire prevention is an aspect that we should pay special attention to. Therefore, in modern buildings, there are special designs of fire-resistant Windows. To prevent the spread of fire in case of an accident, we must pay attention when choosing fire-resistant Windows. Below, Delek Doors and Windows Network will give you a detailed introduction to the features of fire-resistant Windows and the tips for choosing them.
What are the features of fireproof Windows
Fire-resistant Windows refer to those composed of steel window frames, steel window sashes and fire-resistant glass, which can serve to isolate and prevent the spread of fire. Fixed fire-resistant Windows: fire-resistant Windows with window sashes that cannot be opened. That is, sealed and fixed on all four sides. Movable fire-resistant Windows: These are two types of fire-resistant Windows where the window sash can be opened and closed under the action of the fire-resistant window opening and closing device.
(1) The window frame frame adopts a steel or wooden frame with a certain strength to ensure the integrity and stability of the components.
(2) The steel frame and pressure strips can be made of galvanized steel plates or stainless steel plates. The material selection standards comply with the provisions of Article 5.1 of GB12955 "General Technical Conditions for Steel Fireproof Doors".
(3) The material selection standards for the wooden frame and pressure strips shall comply with the provisions of Article 5.1.1 in GB14101 "General Technical Conditions for Wooden Fire Doors".
(4) The filling materials inside the steel and wooden frames should be non-combustible materials.
(5) Fire-resistant glass can be selected from products that do not affect the passing of the fire resistance performance test of the fire-resistant window. The light transmittance of the glass shall not be less than 75% of that of ordinary flat glass with the same number of layers
(6) The sealing material between the frame and the fire-resistant glass should be flame-retardant, which can play a role in fire prevention and smoke isolation during a fire.
(7) The hardware accessories should be standardized matching products that have passed the inspection.
(8) Fireproof window opening and closing device: It must have the function of temperature-sensing and releasing the window sash. Currently, there are integrated (window shutters) and split (fuse devices) available on the market.
Tips for Choosing Fire-resistant Windows
1. Check the certificate
Fireproof Windows are products subject to the type approval system. Before being sold, all products need to undergo type inspection. Generally, the type inspection report provides detailed descriptions of the sample's specifications, dimensions, composition, materials, and product photos, etc. When actually purchasing, it is necessary to request the type inspection report from the manufacturer.
2. Process quality
High-quality steel fireproof doors are firmly welded with evenly distributed weld points. The outer surface is sprayed flat and smooth. There should be product marks, quality inspection qualification marks and quality certification (accreditation) qualification marks at the prescribed positions. A qualified wooden fireproof door should have an intact appearance, no damage, a clean and smooth surface, and no planing marks, burrs or hammer marks. The corners and seams should be cut tightly and smoothly. There should be product marks, quality inspection qualification marks and quality certification (accreditation) qualification marks at the prescribed positions.
3. Comparison values
The external dimensions of qualified products shall be in accordance with the external dimensions described in the sample. The thickness of the door leaf shall be in accordance with the thickness of the door leaf described in the sample. The width of the side walls of the door frame shall be in accordance with the width of the side walls of the door frame described in the sample. The external dimensions of fire-resistant glass shall be in accordance with the external dimensions of fire-resistant glass described in the sample. The thickness of fire-resistant glass shall be in accordance with the thickness of fire-resistant glass described in the sample.
4. Check the level
According to relevant standards, the safety levels of fireproof doors can be classified into Grade A, Grade B and Grade C. Among them, Grade C has the highest anti-theft performance, followed by Grade B, and Grade A has the lowest. Most of the fireproof doors we see in the building materials market are Grade A, which are more suitable for general household use.
5. Check the seal
Qualified steel and wooden fireproof doors should be equipped with fireproof sealing strips, which should be straight and free of arching, and have a qualified test report issued by a national-level testing institution.
The cleaning and maintenance of fireproof Windows should pay attention to the following aspects:
When installing fireproof Windows, it is necessary to carefully fill the cement to ensure an effective and tight bond between the window frame and the wall. This can also maintain a reasonable fit between the window frame and the window frame, and there is no need to worry about deformation during long-term use.
2. When wiping the surface of fireproof Windows with neutral reagents or damp cloths, do not leave them on the window surface for a long time, otherwise the surface will be damaged, causing the surface decorative material to discolor or peel off.
3. To remove the dirt on the surface of the fireproof window, use a soft cotton cloth to wipe. A coin can easily scratch the surface. When the dirt on the rapid door is too heavy, you can use cleaning agents, toothpaste, or special cleaning agents, etc. After removing the dirt, wipe with clean water and then dry.
4. If the resistance is too high when the fireproof window is closed, a little lubricating oil can also be applied to the movable lock tongue.
5. Be careful not to rub the corners of the fireproof window too much, otherwise the surface layer at the corners may fall off.
