6mm 12A 6mm Aluminium Frame Glass Window

Five performances of system doors and windows:

(1) Wind pressure resistance performance: refers to the performance of external doors and windows that are not damaged under wind pressure, such as not easy to crack, profile damage, glass damage, bonding failure, loose hardware opening barriers, etc.

(2) Air tightness: Simply put, it is the ability of outer doors and windows to prevent air infiltration when they are normally closed.

(3) Watertight performance: when doors and windows are normally closed, the ability to prevent rainwater infiltration during wind and rain

(4) Thermal insulation performance: K value for doors and windows.

(5) Sound insulation performance: also known as sound insulation and noise reduction, which means to reduce the sound transmission ability of the sound source to the listener

System doors and windows require watertightness, airtightness, wind pressure resistance of doors and windows, as well as a series of important functions such as heat insulation, sound insulation, noise prevention, and operation feel. The materials used in each sub-module should also be considered.
For example, aluminum, glass, as well as hardware accessories, sealants, auxiliary accessories and screens and other aspects of the performance of the comprehensive results, all indispensable, in accordance with the requirements of the overall solution, design, production and installation, and in actual use, Achieve this series of functions.

System doors and windows means that the K value (energy-saving coefficient) reaches a certain standard, that is to say, heat insulation, sound insulation, waterproofing, aluminum thickness, etc. must meet the standard.

For glass of the same structure, the heat transfer coefficient of different systems has different results.
