When choosing aluminum double-layer folding doors and UPVC Bi folding doors, the following aspects can be considered:
I. Material characteristics
1. Aluminum alloy Bi folding door
- The aluminum alloy material is strong and durable. It has high strength and can withstand a certain degree of external impact without being easily deformed. For example, in household use, if the door is accidentally bumped, the aluminum alloy folding door is relatively more able to maintain its original shape.
- This material has very good corrosion resistance, especially for some coastal areas or environments with high humidity. Because the surface of aluminum alloy will form a dense oxide film, which prevents moisture and corrosive substances in the air from further eroding. For example, for houses by the sea, using aluminum alloy double-layer folding doors can effectively resist the salt corrosion brought by sea breeze.
- The thermal conductivity of aluminum alloy material is relatively strong. In winter, heat is easily lost through the door; but in summer, if there is air conditioning cooling indoors, some cold air will also be lost. However, some aluminum alloy folding doors now adopt broken bridge insulation technology, which can reduce heat conduction to a certain extent.
2. UPVC double-layer folding door
- UPVC (rigid polyvinyl chloride) material has good thermal insulation performance. Its thermal conductivity coefficient is low. Compared with aluminum alloy folding doors, it can better maintain the indoor temperature and reduce heat transfer. This is very beneficial for energy-saving places such as residences and offices.
- The UPVC material itself has better sound insulation performance. Its internal structure can effectively block external noise and create a relatively quiet environment indoors. For example, installed in a room close to the street, it can reduce the interference of noise such as vehicle driving.
- However, the mechanical strength of UPVC material is relatively lower than that of aluminum alloy. When subjected to a large external force, it may be deformed or damaged. Moreover, although its weather resistance is good, long-term exposure to sunlight may cause fading, aging and other phenomena. However, high-quality UPVC products will add anti-ultraviolet ingredients to delay this process.
II. Appearance design
1. Aluminum alloy Bi folding door
- Aluminum alloy Bi folding door have a variety of colors and styles to choose from in appearance. Through surface treatment processes such as anodizing, electrophoretic coating, and powder spraying, it can present different colors and textures. For example, aluminum alloy folding doors treated by anodizing have high surface gloss and metallic texture, and can be well matched with modern minimalist architecture or interior decoration; while aluminum alloy doors sprayed with powder can be customized in various colors according to customer needs, such as wood grain imitation color, so that it has the appearance of natural wood and is suitable for Chinese or pastoral style decoration.
- This kind of door has simple and smooth lines, and the frame structure is relatively slender, which can provide a larger lighting area. In design, it is more fashionable and atmospheric, suitable for large-space partitions or as balcony doors, etc., which can enhance the transparency of the space.
2. UPVC Bi folding door
- The appearance of UPVC folding doors is also relatively diverse. It can be molded through molds to create various shapes, such as European-style carvings and Chinese-style patterns. Moreover, UPVC materials can be co-extruded in two colors to make the inside and outside colors of the door different to meet different decoration needs.
- Its appearance texture is relatively soft and similar to wood materials. However, due to the characteristics of the material itself, its shape may not be as refined and tough as that of aluminum alloy doors, but it can create a more natural atmosphere in some warm and comfortable decoration styles.
III. Price factor
1. Aluminum alloy Bi folding door
- Generally speaking, the price of aluminum alloy bi folding doors is relatively high. This is mainly because the raw material cost of aluminum alloy is relatively high, and its processing technology is more complex, especially for some aluminum alloy folding doors that adopt high-end surface treatment technology or broken bridge insulation technology. However, the price will also vary depending on factors such as the purity, thickness, and brand of aluminum alloy.
2. UPVC bi folding door
- The price of UPVC bi folding doors is usually lower than that of aluminum alloy folding doors. Its raw material cost is relatively low and the production process is relatively simple, so the price is more competitive. But it should be noted that the price of some high-quality UPVC folding doors with special functions (such as super sound insulation, anti-aging, etc.) may increase.
