Broken-bridge aluminum doors and windows are made of insulated broken-bridge aluminum profiles and insulating glass, which have the functions of energy saving, sound insulation, noise prevention, dust prevention and waterproof.
The thermal conductivity K value of Xu Ting broken bridge aluminum doors and windows is below 3W/_ k, which reduces the heat loss by half compared with ordinary doors and windows, reduces the heating cost by about 30%, and achieves sound insulation of more than 29 decibels. The water tightness and air tightness are good, both reaching the national A 1 class window standard.
Advantages of broken bridge aluminum doors and windows in Xu Ting
Xu Ting Broken Bridge aluminum doors and windows have good sound insulation effect: effectively isolate outdoor noise interference and create a quiet indoor environment.
Test conclusion: Sound insulation (35φB) meets the requirements of DID4 109.
The aluminum doors and windows of Xu Ting Broken Bridge have good air tightness: the unique sealing structure can give full play to the space heating effect in a room with heating and cooling equipment.
Test conclusion: 66% energy saving.
The aluminum doors and windows of Xu Ting Broken Bridge have good watertightness: the water absorption rate is 0. 19, and the doors and windows are designed with waterproof boards and drainage troughs, which can completely isolate rainwater from the outside world.
Test conclusion: Watertightness conforms to international GB/T7 108-2002.
The aluminum doors and windows of Xu Ting Broken Bridge have a good sound insulation effect: the structure has been carefully designed and the joints are tight. The test results show that the sound insulation capacity is 30db, which meets the relevant standards.
Xu Ting broken bridge aluminum doors and windows have good fire resistance: profiles are excellent fire extinguishing materials, which do not spontaneously ignite or help combustion, and can extinguish by themselves, thus eliminating fire hazards.
Xu Ting broken bridge aluminum doors and windows have good thermal insulation performance: plastic profiles have low thermal conductivity and good air tightness.
Anti-aging of broken bridge aluminum doors and windows in Xu Ting: imported modifiers and ultraviolet absorbers are used as raw materials, which are resistant to scorching sun, heavy rain, dryness and humidity, and do not change color, embrittle or age at -30℃ to 70℃.
Corrosion resistance of broken bridge aluminum doors and windows in Xu Ting: This profile is not affected by acid and alkali corrosion, waste gas and salt, and it is safe to use in heavy industry areas in coastal areas.
Impact resistance of Xu Ting broken bridge aluminum doors and windows: very special. The profile can bear a heavy hammer of 10kg at-10℃ and will not break when falling freely from 1 m.
Xu Ting broken bridge aluminum doors and windows have good safety: excellent hardware fittings and advanced decorative locks make thieves helpless.
Structural principle of sound insulation of hollow glass
The soundproof window consists of two or three layers of glass and window frames with different thicknesses, and a special soundproof layer is used. Sound insulation layer glass is made of sound insulation layer glass and PVB film firmly bonded at high temperature and high pressure. Or an aluminum alloy partition frame filled with desiccant (molecular sieve) is sandwiched in the middle of the sound insulation layer, and the edge part is bonded with sealant (butyl adhesive, polysulfide adhesive and structural adhesive); Effectively prefabricate the "coincidence effect" and the formed sound insulation groove, and fill the window frame with sound-absorbing materials to fully absorb the sound waves of transparent glass and isolate the noise of each channel to the greatest extent.
