Briefly introduce the built-in hollow louvers (louver glass)

Sources:www.149aa.cn | PublishDate:2025.11.03

      Built in hollow louvers, also known as louver glass, are a new type of energy-saving product that place the louvers between double-layer tempered glass.
Here is a brief introduction:
      Structural composition: It mainly consists of high-quality double-layer tempered glass, built-in aluminum louvers, and a single handle magnetic control mechanism or electric remote control system.
Features
       Energy saving: In summer, the blinds can be closed to block direct sunlight and convection of hot and cold air, reducing air conditioning energy consumption; In winter, the blinds can be lifted up to allow direct sunlight and increase indoor heat absorption. Coupled with the hollow layer barrier, it can improve indoor insulation temperature.
       Soundproofing: Generally, insulated glass can reduce noise by about 25 decibels, and built-in insulated louver glass can reduce indoor noise to 36 decibels, resulting in better sound insulation effect.
       Fireproof: Double layer tempered glass and built-in aluminum magnesium louvers are not easy to burn and will not release thick smoke, which can block the transmission of flames and reduce the risk of fire.
       Dust and pollution prevention: The built-in louver design avoids dust and oil fume pollution, and the magnetic induction transmission system makes the operation of the louvers easy and does not require cleaning.
       Frost prevention: In cold regions, its good air tightness and water tightness can isolate moisture and effectively prevent door and window glass from freezing and frosting.
       Control method: It has the function of raising and lowering the louvers and flipping them up to 180 degrees, which can be operated through manual magnetic control device or electric remote control system.
       Application scenarios: Widely used in enterprises, institutions, residential buildings, hospitals, office buildings and other places, it can create an independent working environment, improve living quality, and prevent the spread of bacteria.
