(2) Ordinary aluminum alloy window: (Advantages) Good weather resistance and aging resistance. (Disadvantages) The heat insulation is not as good as other materials, and the colors are only white and brown.
(3) Plastic steel window: (Advantages) It has good sound insulation, heat insulation, fire prevention, air tightness, water tightness, corrosion resistance and heat preservation. (Disadvantages) After all, it is a PVC plastic profile. After a long time, the surface will turn yellow and the window will be deformed. The service life is 20-30 years.
(4) Broken bridge aluminum alloy window: (advantages) 1.4 or above aluminum material, and all bases are provided with heat insulation layer; It also has good sound insulation, heat insulation, fire prevention, air tightness, water tightness, corrosion resistance, heat preservation and maintenance-free performance. It is a metal aluminum profile, which can be used for a long time without deformation or fading. (Disadvantages) Aluminum is expensive and the production cost is relatively high.
(5) Frameless window: (Advantages) Good lighting, maximum air convection, beautiful appearance and easy folding. (Disadvantages) Poor heat preservation, poor sealing and poor sound insulation.
Summarize the cost performance: under normal circumstances, solid wood windows and ordinary broken bridge aluminum alloy windows will not be selected; The most widely used material is plastic-steel window. The price of plastic-steel window is generally between 150-600 yuan/square meter, which is acceptable to most people. The cost performance ratio of plastic steel windows is the main factor of its hot sale. Broken bridge alloy is a new type of material that has only appeared in recent years. Many of its properties can be compared with plastic steel, and it is more durable than plastic steel. The price is generally 400- 1200 yuan/square meter, which is generally used for villas and high-grade sun rooms. Only a few people follow the trend to use frameless window products, and the price of frameless windows will generally be between 360-700 yuan/square meter.
