1. Profiles
aluminum silicon magnesium alloy broken bridge aluminum aluminum alloy doors and windows heat-conduction coefficient K value is 3W/? Below. K, the heat loss of ordinary aluminum alloy doors and windows is reduced by half, and the heating cost is reduced by about 30%. Inferior profiles on the market use recycled aluminum materials, and then processed, mixed with impurities, the price is cheap, not only does it not have the effect of heat preservation and energy saving, but also has a short life.
2. Glass
compared with single glass, hollow glass has lower conduction coefficient, which effectively reduces the heat conduction through aluminum alloy doors and windows.
3. Sealing Strip
the service life and sealing performance of high-quality sealing strip are naturally higher than that of ordinary sealing strip.
II. Waterproof

These precious time is equivalent to the death of God, the critical moment, without regret.
IV. Sound insulation effect
when choosing aluminum alloy doors and windows, try to choose hollow glass or three glasses. The inner and outer channels are sealed, and EPDM sealant strip is used at the junction of frame glass and profile to strengthen the sealing performance of windows, in order to achieve the purpose of sound insulation function. Generally, the sound insulation reaches 30-40db, which can ensure that residents within 50 meters on both sides of the expressway are not disturbed by noise, and adjacent to the downtown can also ensure the tranquility and warmth of the room.
