Do You Have A Lot Of Question About System Windows And Doors? As the quality of life continues to improve, people have clear requirements for residential quality and performance, in addition to the obvious parts of the purchase of doors and windows such as aluminum, glass, accessories and other quality, relatively more attention to the combination of these doors and windows after a comprehensive performance of the realization.It is the perfect organic combination of a performance system that requires consideration of a series of important functions such as water tightness, air tightness, wind pressure resistance, mechanical strength, thermal insulation, sound insulation and operating feel, as well as the comprehensive results of the performance of equipment, profiles, accessories and seals, resulting in a high-performance system of doors and windows. The difference between system windows and doors performance and non-system windows and doors (1)Wind pressure resistance The five main performance parameters of 'wind pressure, air tightness, water tightness, thermal insulation and sound insulation' are generally used to determine the performance of a system window or door product. System windows and doors will be designed structurally to take into account the basic wind pressure of extreme weather, mostly to a standard of 6-8. For example, the width of the frame is increased, the wall thickness of the profile is increased and the number of cavities is increased. (2)Airtightness, watertightness The two together represent the 'tightness' of a window or door, which refers to the ability to stop rainwater and air from penetrating into the room when the door or window is closed. System sliding doors and windows have a 4-5 level of air and water tightness through the structure of the rubber strip seal, hidden drainage, high and low rails, etc.; the most significant impact on the sealing performance of system windows and doors is the multi-channel sealing structure, which is basically reflected in the "no wind and no rain" after the windows are closed. Warren System windows and doors use a large deformation of one piece of bending glass outside the rubber strip, to solve the problem of glue cracking and rubber strip shrinkage leakage. Imported main sealing strips to eliminate water leakage at the joints. (3)Thermal insulation properties K-value The lower the k-value, the better the ability of the door or window to block the exchange of temperature between inside and outside, i.e. the better the insulation performance of the door or window. System windows and doors with wide thermal insulation strips, more profile cavities, isothermal structure, multiple sealing, cavity filling and lower k-value glass can widen the gap between the thermal insulation and non-system windows and doors. Warren Systems windows and doors have a multi-cavity structure with glass channel insulation wool to improve insulation and airtightness. Optional cavity infusion is also available to improve insulation performance and prevent condensation. E.g. condensation on non-system windows, northern cities, 7 November. (4)Acoustic performance Mainly related to sealing and glass selection, the advantages
