This duct is a new generation of environmentally friendly and energy-saving product that replaces inorganic fiberglass air ducts, fiberglass air ducts, iron air ducts and phenolic air ducts. The surface of the glass-magnesium composite air duct plate is smooth and flat, which greatly improves the air transportation efficiency. During the production, production, installation, and use of this product, the glass-magnesium composite air duct does not produce any environmentally harmful substances, does not rust, mold, or accumulate dust, and does not contain the dust and fibers of fiberglass air ducts; it has no odor. , low thermal conductivity, excellent thermal insulation performance, good sound insulation and sound absorption performance, no noise generated when the iron duct shrinks and expands; non-combustible, anti-bending, pressure-resistant, low water absorption, low temperature expansion, no moisture absorption deformation Phenomenon. As a popular product, glass magnesium air ducts not only meet the market's demand for traditional products, but also realize the performance upgrade of inorganic composite air ducts by improving the energy saving, fire protection and environmental protection index parameters of inorganic composite materials.

We can make mgo boards of various sizes according to needs. Insulation panels are widely used in construction and industrial fields to improve the thermal performance of buildings and equipment, reduce energy consumption and improve indoor environment.
The following are common application areas for our boards:
Excellent fire protection
Beiyuan magnesium oxide has good fire resistance and is a non-combustible board, reaching the highest fire-proof and non-combustible grade A1.
Pest and mold resistance
BeiYuan MgO board anti-mold,anti-bacteria,anti-insect and anti-termite function,meet the European and American etc building materials anti-mold standard.
Sound Insulation
Excellent sound insulation performance ensures a quiet and elegant environment. The sound insulation of 6mm thick plate is 29dB, which is greater than 42dB.
Superior bending strength
It has a dense structure, good stability, no deformation, and has wood-like toughness. It has excellent impact resistance, compression resistance, tensile resistance, and fracture resistance. It is rigid and tough.
Waterproof and moisture-proof
The performance is stable and not affected by condensation of water droplets and humid air. Even if it is soaked in water for several days and taken out to dry naturally, it will not deform or soften.
Light weight
The apparent density of Beiyuan magnesium oxide is 0.8-1.2g/cm3, and its light weight is beneficial to the structure's earthquake resistance, effectively reducing the cost of the foundation and main structure.
High durability
The scientific formula completely solves the problems of moisture absorption and halogenation of glass magnesium fireproof board. After ten years of testing, the magnesium glass fireproof board is strong and durable, resistant to aging and has a long life.
Environmentally friendly and healthy
It does not contain asbestos, formaldehyde, benzene and harmful radioactive elements. It is smoke-free, non-toxic and has no odor when exposed to fire. Natural mineral powder and plant fiber raw materials, energy saving and environmental protection.
Heat insulation and energy saving
The inorganic material has good properties, with a thermal conductivity of 0.216w/cm-k, which is more insulating than the 1.1w/cm-k of Ai sand blocks, saving energy consumption and keeping the room comfortable and beautiful.
Multifunctional product
Unique smooth and rough surfaces provide functional versatility for customer use. The smooth surface can be pasted with wallpaper, spray paint or latex paint, etc.; the rough surface can be pasted with ceramic tiles, dust and latex paint.
High quality and competitive price
