Aluminum alloy doors and windows
Influenced by traditional consumption habits, aluminum alloy doors and windows still dominate the market, occupying nearly half of the doors and windows market. In addition, due to the advantages of low price, high strength, no aging, no fading, and strong ductility, aluminum alloy doors and windows are favored by ordinary consumers.
Of course, the quality of aluminum alloy doors and windows is also worrying, professional manufacturers in the market lack of competitiveness, private, individual assembly households throughout the urban and rural areas, most of the lack of professional knowledge, rough manufacturing doors and windows, profile oxide film thickness, sealing quality , mechanical properties, elongation and other unqualified people, the thickness is not enough, cutting corners is common, affecting the healthy development of aluminum alloy doors and windows.
Steel doors and windows
Under the guidance and support of the country’s macroeconomic policies, steel doors and windows have been increasingly favored by merchants in the market in recent years. In some large and medium-sized cities such as Shanghai and Beijing, the market share of plastic steel doors and windows has reached 60%, becoming the leading product in the door and window market. In other provinces such as Shandong, plastic steel doors and windows are also becoming a consumer highlight and fashion on the market. Although the price is relatively high, with its many advantages such as good airtightness, heat preservation and energy conservation, it is quite competitive in the market and has become the preferred new building material for energy-saving buildings.
Solid wood doors and windows
With the increasing popularity of green and environmentally-friendly building materials and changes in consumer attitudes, the solid wood doors and windows that were once rejected by the market are making a comeback and are loved by home remodelers. This type of solid wood doors and windows, mostly work fine, distinguished and elegant, or European carved, or combination of style, or ancient rhyme still, or simple and lively, interpretation of a different bedroom mood.
Solid wood doors and windows have the characteristics of soft texture, good sound insulation, natural color, and simple texture, giving people a feeling of affinity and warmth. Although they are expensive, they are still loved by many families. Especially the interior bedroom doors and bathroom doors, many families choose solid wood doors and windows, together with solid wood flooring, giving the feeling of returning to nature. In addition, empty plywood doors and windows also occupy a certain market.
Broken bridge aluminum doors and windows
Broken aluminum doors and windows, also known as aluminum-plastic composite doors and windows, using insulated aluminum and hollow glass insulation, with energy saving, noise, noise, dust, waterproof and other functions. The thermal conductivity K of the broken bridge aluminum doors and windows is less than 3W/m2?K, which is less than half of the heat loss of ordinary doors and windows, lowers the heating cost by about 30%, and the sound insulation amount is more than 29 decibels. The watertightness and airtightness are good and reach the national level. Class A1 window standard.
The advantages of broken aluminum doors and windows:
⊙Reduce heat conduction: Heat insulation broken aluminum alloy aluminum alloy profiles, the thermal conductivity of 1.8 ~ 3.5W/m2 · k is much lower than ordinary aluminum alloy profiles 140 ~ 170W/m2 · k; the use of hollow glass structure, its thermal conductivity The coefficient is 3.17~3.59W/m2·k which is much lower than the common aluminum alloy 6.69~6.84W/m2·k, which effectively reduces the heat transmitted through the doors and windows.
⊙ Anti-condensation: The temperature of the inner surface of the profile with heat-insulated bars is close to the room temperature, reducing the possibility that the room water will condense on the surface of the profile due to over-saturation.
⊙Energy saving: In winter, the window frame with thermal insulation strip can reduce 1/3 of the heat lost through the window frame; in summer, if there is air conditioning, the window frame with thermal insulation strip can be more Reduce energy loss more.
⊙ Protecting the environment: Through the application of thermal insulation systems, energy consumption can be reduced while reducing the environmental radiation due to air conditioning and heating.
⊙ Health: The exchange of heat between the human body and the environment depends on the temperature of the indoor air, the speed of air flow, and the temperature of the outdoor air. By adjusting the interior temperature of doors and windows so that it is not lower than 12 ~ 13 °C, has reached a more comfortable environment.
⊙ Reduce noise: Using hollow glass structures with different thicknesses and heat-insulating and broken aluminum profile structures can effectively reduce the resonance effect of sound waves, prevent sound transmission, and reduce noise by more than 30 dB.
Colorful enamel color: The use of anodizing, powder coating surface treatment can produce RAL color more than 200 different colors of aluminum profiles, after rolling combination, so that insulating aluminum doors and windows produce indoor and outdoor different color two-color windows.
