Youshi Glass Magnesium Compositeair ductIt is a new type of high-tech composite board, which is made of high-quality magnesium oxide, magnesium chloride, alkali resistant fiberglass cloth and inorganic adhesive rolled by modern technology. It has the characteristics of light weight, high strength, non combustion, sound insulation, heat insulation, moisture resistance, water resistance, and long service life. It is a new generation of environmentally friendly and energy-saving air ducts that replace inorganic glass ducts and glass fiber ducts. The product structure is a three-layer composite, consisting of two layers of high-strength inorganic materials inside and outside, and an intermediate layer of insulation material.

Youshi glass magnesium composite air ducts are mainly used in the fields of construction, decoration, fire protection, etc., especially suitable for the decoration of crowded places such as restaurants, hotels, shopping malls, as well as projects in damp environments such as basements, civil defense, and mines.

Characteristics of Youshi Glass Magnesium Duct Products:

1. Excellent fire resistance performance

The Youshi glass magnesium air duct is made of non combustible inorganic materials and insulation materials, which are combined in one go through high-tech technology. After inspection by the National Fire resistant Building Materials Quality Supervision and Inspection Center, it is classified as an A-level non combustible building material (composite material overall A-level). The special adhesive and accessories for glass magnesium ducts are made of Class A non combustible materials.

2. Ultra high strength performance

Youshi glass magnesium air duct has high strength, with a flexural strength greater than 1.8MPa, and can withstand wind pressure of 3000Pa, which can meet the needs of high, medium, and low-pressure air systems.

3. Excellent moisture and water resistance performance

Youshi glass magnesium air ducts are not afraid of water and do not rust or corrode in humid environments. Even when immersed in water, they can maintain high strength, with a wet strength of over 97%

4. Can effectively improve the net space of the ceiling

The Youshi glass magnesium air duct adopts the non flange connection process, which eliminates the height of the flange and can improve the net space of the ceiling.

5. Lightweight, reducing building load

Youshi glass magnesium air duct weighs 7.5kg per square meter, which is 25% lighter than iron sheet air ducts and can effectively reduce building loads.

6. Beautiful appearance

The Youshi glass magnesium air duct adopts a seamless connection, with a flat bottom surface and an overall beautiful appearance

7. Improve indoor air quality

Youshi glass magnesium air duct does not rust, mold, accumulate dust, breed bacteria or fungi, has no dust or fibers, has no odor, does not produce granular or gaseous pollutants or biological aerogels, and can improve indoor air quality. Tested by authoritative departments.

8. Environmentally friendly products, harmless to humans

As a new type of green and environmentally friendly building material, Youshi Glass Magnesium Duct has taken effective environmental protection measures in terms of raw materials, process formulas, and production processes. Ducts do not produce substances that pollute the environment during production, manufacturing, installation, or use. Even in the event of a fire, the smoke produced by air ducts does not contain toxic substances and is harmless to human health. Therefore, Youshi glass magnesium duct is an environmentally friendly duct.

9. Long lifespan, saving long-term investment

The design structure of Youshi Glass Magnesium Duct products is reasonable, with reliable performance and stable quality, and a service life of over 20 years
