Nowadays, the main materials of balcony sealing are plastic steel doors and windows and aluminum alloy doors and windows, which are basically eliminated. The materials of balcony sealing are mainly broken bridge aluminum windows integrated with window screen windows and broken bridge aluminum windows, then why are there more than 300 yuan per square meter and some more than 600 yuan per square meter for broken bridge aluminum windows in the market? There are even thousands of yuan per square meter
Nowadays, the main materials of balcony sealing are plastic steel doors and windows and aluminum alloy doors and windows, which are basically eliminated. The materials of balcony sealing are mainly broken bridge aluminum windows integrated with window screen windows and broken bridge aluminum windows, then why are there more than 300 yuan per square meter and some more than 600 yuan per square meter for broken bridge aluminum windows in the market? There is even a price of thousands of yuan per square meter. Why are they so different? The impact is mainly due to the aluminum price, hardware price, glass price, accessories price and so on.
1. The price of aluminum materials; Different manufacturers have different aluminum components, and different processes have created the price gap of aluminum materials. The cheap broken bridge aluminum profiles cost 17000 yuan per ton, and the expensive broken bridge aluminum profiles reach 29000 yuan per ton, the difference of one ton of materials is 12000 yuan, which can produce 90 square meters of windows, and the difference of each square meter can be more than 133 yuan.
2. Price difference of hardware: the low-priced hardware is mainly made of domestic hardware. The price of a set of domestic broken bridge aluminum hardware is as low as 40 to 50 yuan, and the expensive one is only 100 yuan per set, however, a set of imported hardware costs 400-500 yuan, and the price difference is obvious.
3. Glass price: cheap hollow glass uses inferior sealant to seal the glass. This kind of glue releases a lot of formaldehyde and harms health, especially in summer, it can always smell pungent odor, the cost is only 70 yuan per square meter. The high-quality hollow glass is sealed by silicone adhesive, and the double-layer tempered glass costs 16 yuan per square meter.0 yuan, the cost difference is 90 yuan/square meter.
4. Accessories Price: accessories mainly include sealant strips, corner codes, installation silicon sealant, etc. The difference between high-quality materials and cheap ones is more than 50 yuan per square meter, in short, if you get what you pay for and have different configuration requirements, their prices are also very different.
Precautions for sealing the balcony:
1. The profiles (Broken Bridge aluminum, plastic steel, aluminum alloy) selected for sealing the balcony must be products that meet the national standards, without deformation, damage, or secondary points, and the hardware accessories should be the same;
2. Before installation, the dirt and residue around the balcony must be cleaned up, and the original armrest of the balcony must be removed or sealed;
3. The size of the window and door should be smaller than that of the original balcony, especially at the bottom of the window, a spacing of 1cm should be set aside and filled with elastic mineral wool or special sealing foaming agent. It can not only prevent the window frame from being deformed by hot and cold replacement, but also prevent rainwater leakage;
4. After the window frame is filled around, make another layer of waterproof layer. After drying, paste the veneer, but do not block spillway hole;
5. Special screws must be selected for installation Fasteners. The window frame must be vertical and horizontal, and the error cannot exceed 0.3mm;
6. After installation, make sure that doors and windows are opened or moved without resistance.
The price of sealed balcony and sealed balcony, the price of plastic steel window is generally between 200-600 yuan/square meter, the insulation performance is not very good; Broken Bridge aluminum is a new material, the price is 300-1200 yuan/square meter, many of its properties can be compared with plastic steel, but it is more durable than plastic steel, and is used in villas, sun rooms and other residences; Fewer people use frameless windows, the price of frameless windows is generally between 360-700 yuan/square meter.
