Composed of wood-plastic-aluminum three parts, energy-saving and low-carbon architectural passive doors, energy-saving impact doors and windows have obtained German PHI certification, and the U value of the whole door is lower than 0.8W/M²K; energy-saving impact doors and windows are also called “passive house doors and windows” Passive buildings, ultra-low energy buildings, are houses that can meet cooling and heating needs without an active supply of energy. Simply put, it is a highly energy-efficient and highly comfortable, and livable building.
The advanced energy-saving design concepts and construction technical standards of passive energy-saving buildings have greatly improved the building’s thermal insulation, heat insulation, sound insulation, air tightness, water tightness, and wind pressure resistance. Coupled with the high-efficiency heat (cold) recovery device of the fresh air system to recycle the heat (cold) in the indoor exhaust air, thereby significantly reducing the heating and cooling needs of the building, passive doors and windows dedicated to passive houses.
The U value of the whole window is only ≤0.8 watts per square meter Kelvin (W/㎡·K);
