aluminum alloy doors and windows are popular because of their high quality, which mainly depends on the characteristics of aluminum. Due to its low thermal conductivity, it is more insulated and energy efficient. However, because the price of aluminum doors and windows is much higher than that of plastic steel windows and doors, the current market share is small.
Compared with plastic-steel doors and windows, aluminum-wood doors and windows have some other characteristics. Aluminum doors and windows have outstanding advantages in terms of thermal insulation performance. This is because the heat transfer coefficient of wood is only 1.3, which is far lower than that of plastic steel doors and windows 2.2. It can be seen that the heat insulation performance of aluminum doors and windows is stronger.
Service life Due to the use of inferior hardware, plastic steel doors and windows are broken by macromolecular chains under the action of ultraviolet rays, causing the surface to lose gloss and discolor. Plastic steel doors and windows are easily deformed by heat, become brittle when cold, have poor stability, and are not easy to open and close smoothly. Plastic steel door and window hardware is also easily damaged. Unlike them, Aluminum doors and windows have strict material selection, and have selected international hardware brands based on their service life.
