Broken bridge aluminum doors and windows and ordinary aluminum doors and windows vary greatly
The price of a sub-goods will never change, mainly the following: 1. Good insulation: aluminum-plastic composite profiles in the plastic thermal conductivity is low, the insulation effect is better than aluminum 1250 times, 2. Sound insulation is good: its structure has been carefully designed, tight seams, test results, sound insulation 30 db, in line with the relevant 3. Impact resistance: As the outer surface of aluminum-plastic composite profile for the aluminum alloy, so it is better than plastic steel window impact 4. Good air tightness: aluminum-plastic composite window of the joints are equipped with multi-channel sealed tops or strips, air tightness for a 5. Watertight: windows and doors designed with rainwater structure, the rain completely isolated from the outdoor, 6 Good fire resistance: aluminum alloy for the metal material, do not burn. 7. Anti-theft: aluminum-plastic composite window, excellent configuration of hardware accessories and senior decorative locks, so that thieves helpless 8. Maintenance-free: aluminum-plastic composite profiles are not susceptible to acid-base erosion, will not turn yellow fade, almost no maintenance.
Aluminum door is the surface treatment of aluminum alloy profiles, by cutting, drilling, milling, tapping, production, assembly and other processing technology made of the door frame components, and then connectors, sealing materials, open and close the hardware accessories , The glass is assembled together.
Broken bridge aluminum doors and windows, the use of insulated bridge aluminum and hollow glass, with energy saving, noise, noise, dust, water and other functions. The thermal conductivity of the aluminum windows and doors of the bridge is limited to 3W / ㎡ · K, which is less than half of the heat loss of ordinary doors and windows, reducing the heating cost by about 30%, the sound insulation is more than 29 dB, the watertight, Good sex, all up to the national A1 class window standard.
