2) Specifications and dimensions.
3) Aluminum alloy doors and windows are classified into three categories: A (high-performance doors and windows), B (neutral energy doors and windows), and 1C (low-performance doors and windows) based on three performance indicators: wind pressure strength, air permeability (airtight), and rainwater permeability (watertight). According to the sound insulation performance of the air, it is divided into four levels, with a sound insulation level of 2 sdB for sound insulation doors and windows. According to the thermal insulation performance (thermal insulation performance), it is divided into three levels, and the second thermal resistance value is 0.25m'K/W, which is the thermal insulation door and window). The treatment methods of surface facial mask of aluminum alloy doors and windows include anodic oxidation method and anodic oxidation method; Composite surface film method.
⑶ Marking rules for aluminum alloy door and window products: When users choose aluminum alloy doors and windows, they first choose the appropriate door and window based on the size of the room. Select the appropriate type of door and window according to the usage requirements based on the specifications and dimensions. Secondly, determine the various performance requirements of the doors and windows based on their usage areas (such as inner and outer doors), such as windows and standard doors, which require certain insulation, sound insulation, water tightness, and air tightness requirements. Finally, the user selects the appropriate color for the door and window frames based on their own preferences and matching with other decorative parts.
