Features and Advantages
878 Product Characteristics
  • Characteristic 1: the width of right and left parts of the outer frame is 70mm; a great many EPDM adhesive strips with excellent property are adopted, and air-tight grooves are especially designed to make the structure stronger with excellent soundproof and air-tight properties.
  • Characteristic 2: a special stepped design of five layers is adopted for the bottom rail of the outer frame with great height differences and excellent water-tightness. Meanwhile, a special hollow design is adopted so that deforming or bending will not occur easily.
  • Characteristic 3: a corner connecting method is innovatively designed to not only make window types three-dimensional and have more variations and a wider scope of application, but also provide clients with more choices.
  • Characteristic 4: both the inner frame and the window screen adopt adjustable rollers, and the heights of the rollers can be freely adjusted to regulate errors generated by the installation of screen windows. There are single and double rollers. Their shells adopt stainless steel and their inner cores adopt ball bearings, so they can endure great stress. They can automatically distribute the weight of sashes on the two rollers evenly. Therefore, the two rollers will endure the stress equally to guarantee extended service life and smooth sliding.
  • Characteristic 5: two alternating soundproof and air-tight adhesive strips are designed at the two sides of the inner frame to strengthen its air-tightness and soundproofing and to prevent dust from entering. When the double air-tight sashes are closed, an optimal air-tightness effect will be achieved.
  • Characteristic 6: an inner disassembling design is adopted for the inner sash, and an wind-stopping and burglar alarm device is especially added to enhance the function of burglar alarm and anti-drop. When cleaning the sashes, they can be disassembled indoors just by removing the burglar alarm device.

  • The vertical material of the inner frame of the 878 series adopts a hollow design. The superimposed hollow vertical material forms a powerful columnar pressure-resistant structure with excellent wind pressure strength. The same guide vane is added to the upper and lower parts to enhance its firmness, prevent the wind and rain from infiltrating, and improve its air-tightness. Seal plates are installed at the upper and lower parts to make the product beautiful and practical and prevent the aluminum frame from being scratched when sliding.
  • An inner disassembling design is adopted for the inner sash, and an wind-stopping and burglar alarm device is especially added to enhance the function of burglar alarm and anti-drop. When cleaning the sashes, they can be disassembled indoors just by removing the burglar alarm device. Since it is convenient and safe to clean and maintain, a common family member can operate it.
  • Smart ventilation system

  • 878 series is compatible with existing ventilators in the market, realizing a smart ventilation system in home furnishing and a smart life featured by good health, high security and energy-saving.
  • Working principles of the smart ventilation system

  • A pressure difference exists between indoor and outdoor air, and the air will flow through the open ventilator when the pressure difference is balanced. The pressure difference is usually caused by indoor and outdoor temperature difference and the wind pressure outside high-rise buildings, and ventilation is thus formed. By combining with the hardware and monomer ventilators of the flat top-hung window, monomer ventilators will provide a healthy, safe and energy-saving smart ventilation system.
  • Differences between smart ventilators and traditional ventilators

  • Except ventilation, a series of special auxiliary functions like noise reduction, heat recovery, air filtration, humidity and temperature regulation are introduced, and many disadvantages of ventilation by opening the windows are resolved, and thus ventilators are intelligentized.
  • The so-called smart ventilators are ventilator equipment with special functions.
  • Smart ventilators are supplements to high-end doors and windows.
  • 888 series is highly recommended by designing institutes and national key project thanks to its high performance. is widely used in hotels, villas, apartments, holiday villages, urban communities and senior clubs.

  • High performance

  • The water jacket of the 878 series sliding air-tightness window is strengthened to enhance the water-tightness of the whole window and prevent the rain from infiltrating. The guide rail is equipped with a gap-covering rod to enhance the air-tightness, water-tightness, energy conservation and heat preservation.
