UPVC Doors refer to doors made of polyvinyl chloride (UPVC) material, which are widely used in modern buildings due to their durability, waterproof, sound insulation, and easy maintenance. UPVC material is very suitable for making doors because it is not easy to rot, deform or get damp, and can effectively block external noise and air infiltration. UPVC Doors do not require constant painting or maintenance, so they are a very economical and practical door option.

upvc-doors | Advantages and disadvantages of aluminum doors
1. The advantages of aluminum alloy doors: 1. Very good decorative effect: The aluminum alloy door can be made into various colors and shapes, and the surface is shiny, the frame glass ratio is small, and the aluminum alloy door can be made into a large size compartment, which has a modern sense and beautiful appearance, which can add luster to the building. 2. Performance: The aluminum alloy door adopts heat-insulating profiles and hollow glass, which still has good energy-saving effects and is non-frosting and non-condensing. It can meet the needs of any high-level and high-rise buildings. It is a recognized medium and high-level door product at home and abroad. 3. Good processing performance: Aluminum profiles can be processed into large sizes and complex cross-sectional shapes with high dimensional accuracy. The processing technology of aluminum alloy doors is relatively simple and easy to modernize. 4. Strong corrosion resistance: The aluminum alloy oxide layer does not fade, does not fall off, does not need to be painted, is easy to maintain, and does not need to be repaired. 5. Good durability: After good surface treatment, the aluminum profile has good resistance to atmospheric corrosion, not afraid of moisture, not afraid of sunlight, high temperature and no deformation, low temperature and no embrittlement, no burning, no aging, lightning protection, good stability, and suitable for Various climatic environments. 6. Light weight: The density of aluminum profile is 1/3 of that of steel, and its specific strength is high. The aluminum profile for windows per square meter is about 5KG, steel is 10-20KG, and plastic window frames weigh more than 10KG. 7. Conducive to environmental protection: Scrap aluminum is easy to recycle and has a high reuse rate. There is no environmental pollution problem during the processing and production process. 2. Disadvantages of aluminum alloy doors: 1. The larger disadvantage of aluminum alloy door is its sealing performance. Aluminum alloy door has poor sealing performance. If the plastic on the aluminum alloy door is used for a long time, it will fall off, which will lead to poor waterproof performance in rainy days. After a long time, the aluminum alloy door will be oxidized, and the entire appearance will be seriously affected. 2. In addition, the thermal conductivity of aluminum alloy is very high, and the thermal insulation and thermal insulation properties are relatively poor. 3. Although there are many aluminum alloy doors on the market, the aluminum materials used are all energy-intensive products. The aluminum ingots are produced through electrolytic aluminum technology. Each ton of aluminum ingots consumes 1,200 tons of electricity, so the cost of aluminum alloy doors It is relatively high, so the price on the market is relatively high.
