"China Construction · Binhu Design Headquarters" project is located in Tianfu New Area, and its main functions are office, supporting business and underground garage, etc. After completion, the project will be used as the third office area of China Architecture Southwest Design and Research Institute.

Garage is a very important functional division of building groups. A perfect and reasonable regional planning can bring economic benefits and maximize the utilization of building groups. Inside the underground space, the ceiling is covered with fire pipes, ventilation pipes and hVAC pipes. The finished glass fiber duct is easy to be inserted into the construction, which is more convenient and quick for construction.

The tightness and complexity of underground space lead to poor direction resolution of people, blinding effect of vision, closed air and no circulation, and the role of hVAC pipes and ventilation systems are highlighted.

In addition to the rationality of the comprehensive design of the underground space building, it is necessary to consider the moisture proof and heat preservation of the air duct in the underground passage. The raw material of glass fiber duct is glass wool. Glass wool is a kind of inorganic fiber. The raw materials are dolomite and quartz stone, which belong to A1 class non-combustible materials. Glass fiber duct made by integrated machinery can be applied to the environment of underground commercial space and garage.

The use of fireproof and moisture-proof fiberglass air duct can bring large buffering and ventilation to the air and environment of underground space and ensure fresh air circulation. Fiberglass duct can also absorb the noise generated when the pipe is used, and give people a quiet place for leisure and work.

This new type of air duct adopts formaldehyde-free glass wool plate. It is a new type of air duct developed in order to adapt to new technology and new materials. It is based on this super fine fiber board and compounded by special processing. The plate has excellent sound absorption, noise reduction, energy saving and heat preservation functions. And formaldehyde-free environmental protection composite glass fiber duct light in quality, high density, high strength, is light and high strength air conditioning ventilation duct, can greatly reduce the load of the building. Compared with the traditional iron duct, it is more suitable for the design needs of modern buildings and can maintain the aesthetics of the building space.

Formaldehyde-free environmental protection composite glass fiber air duct has significant performance advantages, small air leakage, simple production and installation -- all depend on the middle layer material of the air duct and the glue and tape used when sealing, and uetersen uses thermal sensitive tape, pressure sensitive tape, water-based glue, repair glue, etc.

The middle layer of fiberglass duct is made of formaldehyde-free environment-friendly glass wool sheet with a density of 80 kg/m³. Its inner layer is coated with nano-polymer coating, which has excellent sound-absorbing and antibacterial moisture-proof properties. Many large buildings, such as shopping centers, theaters, hotels, and even apartments and villas, are recommended to use formaldehyde-free glass fiber muffler air ducts. It can not only absorb sound and reduce noise, but also be formaldehyde-free and environmentally friendly, and keep indoor air clean. These are the embodiment of good performance of glass fiber duct.

Technical innovation of thermal insulation materials can guarantee the safety of the built environment and people's property. It also brings convenience and comfort to life and work, which is also a systematic improvement and progress of a building. Uetersen formaldehyde free environmental protection composite glass fiber duct, in the installation or use, do not need to worry about becoming "human meat formaldehyde removal machine".
