What are the national standards for broken aluminum doors and windows?
In the summer, if there is air conditioning in the case, with a heat shield of the window frame can be more to reduce the loss of energy 4. Protection of the environment: through the application of thermal insulation system, can reduce energy consumption, while reducing the Air conditioning and heating generated by environmental radiation .5. Health: the human body and the environment exchange heat depends on the indoor air temperature, air flow speed and outdoor air temperature by adjusting the indoor and outdoor temperature, so that it is not less than 12 ~ 13 ℃, To achieve the most comfortable environment. 6. Reduce the noise: the use of different thickness of the hollow glass structure and insulation bridge aluminum cavity structure, can effectively reduce the resonance effect of sound waves, to prevent the transmission of sound, can reduce the noise above 30dB. Colorful color: the use of anodizing, powder coating, fluorocarbon spray surface treatment can produce different colors of aluminum, after rolling combination, so that the insulation of aluminum doors and windows to produce indoor and outdoor different colors of the two-color windows
Broken aluminum doors and windows of the specifications: strip to use imported EPDM products, its service life of 30 years, poor quality product life is only about 5 years. Sealant to use silicone weathering adhesive
Natural color, the smell should be not pungent, not strong. Pull. Stretch: Rally strong, flexible, not easy to fold.
High-quality aluminum doors and windows used in aluminum, thickness, strength and oxide film, etc., should comply with the relevant national standards, wall thickness should be more than 1.2 mm, tensile strength of 157 Newton per square millimeter, yield strength to reach per square millimeter 108 Newton, the oxide film thickness should reach 10 microns. If you can not meet the above criteria, indicating that this is a poor quality aluminum alloy doors and windows, can not be used.
The thermal conductivity coefficient of the aluminum windows and doors of the broken bridge is 3W / ㎡ · K, which is lower than that of the ordinary, and the heat transfer coefficient is 3W / Doors and windows heat loss by half, reduce the heating costs of about 30%, the sound insulation of 29 dB or more, watertight, air tightness is good, all up to the national A1 class window standard. Priority selection of high quality insulating glass, the original film is float glass, Standard is 5mm. Between the two pieces of glass between the aluminum and the thickness of the 12mm-15mm between. According to the doors and windows profiles specifications. Door and window hollow glass area is greater than 1.5 square meters to be steel processing. In the professional professional glass processing enterprises Production, Tianjin, more reliable manufacturers have 100 Thai and so on.
