Choose energy-saving door window not careless
Many people buy a house not focused on residential building door window, glass, just from the feeling on the appearance beautiful line. Industry insiders point, doors and Windows and glass is not only the eyes of buildings, or building energy efficiency in key structure. Teach you a few little skill, the hope can help you.
Form the bigger the not energy saving
Form large heat is glass, not window frame, glass window of different types of 70% to 90% of the area. Building the in common use in the window type, generally for push-pull window, make the same score a window and fixed window.
The structure of push-pull window decided it is not an ideal energy saving window; Speaking from the structure, make the same score a window than push-pull window has obvious advantages.
Fixed window window frame embedded in the wall inside, glass in the window frame, directly with the glass and window frame seal to contact with the quads seal. Normally, have good water tightness and air tightness, air is hard to through the sealant form convection, so convection heat loss is few.
High-tech glass bring energy revolution
In addition to the window, and the choice of glass. Glass material coefficient, the sun light transmission rate, relative to heat and heat transfer coefficient as indexes, the architecture of the indoor thermal environment and heating and cooling energy consumption impact, therefore, in decorating choice should know some energy saving of glass material, performance, use, etc.
The currently used several energy saving glass material basically has coated glass, hollow glass and with thin type heat reflecting material glass. General building doors and Windows accounted for more than 40% of building energy consumption, such as coated glass main have solar thermal reflection glass, low radiation glass and multi-function coated glass.
Heat insulation aluminum alloy doors and Windows of the new technical characteristics and advantages
The principle of heat insulation aluminum alloy doors and Windows in the midst article heat insulation aluminum, aluminum disconnect the formation, effectively prevent the quantity of heat conduction. Heat insulation aluminium alloy profile than the thermal conductivity of door window insulation aluminium alloy profile doors and Windows 40 ~ 70% lower. Heat insulation aluminum alloy doors and Windows of the new technical characteristics: Application heat insulation aluminium alloy profile. Use rolling way inside and outside and heat insulation aluminum alloy article combined together.
With hollow glass, improve the heat preservation performance and sound insulation effect.
The independent seal structure, push-pull window is used double strip double over the tops of four sealing structure; Casement Windows and use and pressure principle, using a hard seal and two word soft seal three seal structure, with excellent air tightness and water tightness. Chooses high-grade accessories, beautiful modelling, flexible operation, safe and reliable, which is beneficial to the doors and Windows of insulation effect.
Heat insulation aluminum alloy doors and Windows advantages: Reduce quantity of heat conduction: the heat insulation aluminium alloy profile, and the heat transfer coefficient is 1.8 ~ 3.5 W/m2 k. · h greatly lower than normal aluminium alloy profile 140 ~ 170 W/m2 k. · h; With hollow glass structure, its heat transfer coefficient is 3.17 ~ 3.59 W/m2 k. · h greatly lower than normal aluminium alloy profile 6.69 ~ 6.84 W/m2 k. · h, reduce the heat conduction through doors and Windows.To prevent condensation: heat insulation materials with article the inner surface of the temperature of close, reduce indoor water for supersaturated and condensation in the possibility of the material surface.
Energy saving in winter, with heat insulation window frame can reduce the article through the window frame lost a third of the heat; In the summer, if is in air conditioning, the heat insulation of the window frame with article can reduce energy losses more.
Protect the environment: through the application of heat insulation system, can reduce the energy consumption and reduce the air conditioning and heating caused environmental radiation.
Good health: the human body and the environment depends on the quantity of heat exchange indoor air temperature, air flow rate and outdoor air temperature. By adjusting the doors and Windows of indoor temperature, make its are not less than 12 to 13 ℃, has reached the most comfortable environment.
Reduce the noise: the different thickness of hollow glass structure and heat insulation aluminum cavity structure, can effectively reduce acoustic resonance effect, prevent the transmission of voice, can reduce the noise 30 dB above.
Color is rich and colorful: by anodic oxidation, powder coating surface treatment can produce RAL lubricious department after more than 200 different colors of the aluminum, the combination of rolling, the heat insulation aluminum alloy doors and Windows produce indoor and outdoor different colors of double lubricious window.
