One、How much does a fire-resistant window cost per square meter?
Fire-resistant windows are windows that meet the requirements for fire resistance and integrity. They are composed of steel window frames, steel window sashes, and fire-resistant glass. Due to their unique construction materials, fire-resistant windows typically have a different price compared to ordinary windows. Fire-resistant windows sold on the market typically range from 300-800 yuan per square meter. Fire-resistant windows made of steel frames and high-quality fire-resistant glass are more expensive, typically ranging from 1000-2000 yuan.
II. Fire-resistant door and window selection guide
1、 Inspect the building
Steel fire-resistant doors and windows offer a reasonable price, but they are heavy, difficult to open, and have a limited range of styles, making them suitable for industrial buildings and general-grade residential buildings, or for areas with low aesthetic requirements and low traffic volume (such as server rooms and garages). Wooden fire-resistant doors and windows are lightweight, easy to operate, and have a good aesthetic appearance with a variety of styles, but they are more expensive and are often used in mid-to-high-end residential buildings or important areas. For interior home use, wooden doors and windows also have a better aesthetic appearance.
2、Check the markings
Fire-resistant doors and windows should have permanent, clearly visible signage. The signage should include the following information: product name, model specifications and trademark, manufacturer name or trademark, and factory address, production date and batch number, and applicable standards.
3、Inspect the appearance
Wooden fire doors and windows: Edges and joints should be tight and smooth; plywood should not be planed to expose the surface; the surface should be clean and smooth or sanded; coatings should be uniform, smooth, and glossy.
Steel fireproof doors and windows: The surface should be smooth and glossy; coatings and plating should be uniform, smooth, and glossy; welds should be strong and evenly distributed; the outer surface of welds should be polished smooth.
4、Inspect the sealant
Qualified steel/wood fire-resistant doors and windows should be equipped with fire-resistant sealing strips. These strips should be straight and free of any bulging, and should have a qualified inspection report issued by a national-level testing agency.
5、Regarding dimensions
The external dimensions of qualified fire-resistant door and window products should be less than or equal to the dimensions specified in the sample description. The door leaf thickness should be greater than or equal to the door leaf thickness specified in the sample description. The width of the door frame side wall should be greater than or equal to the width of the door frame side wall specified in the sample description. The external dimensions of the fire-resistant glass should be less than or equal to the external dimensions of the fire-resistant glass specified in the sample description. The thickness of the fire-resistant glass should be greater than or equal to the thickness of the fire-resistant glass specified in the sample description.
6、Review the report
Fire-resistant doors and windows are products subject to type approval, and require type testing before sale. The type approval report typically includes detailed specifications, dimensions, composition, materials, and photos of the sample. When purchasing, it is necessary to obtain the type approval report from the manufacturer.
