无机玻璃钢通风管道又称为玻镁风管，
无机玻璃钢通风管道又称为玻镁风管，是以改性菱镁水泥为胶结料，掺入有机或无机填充料，并用中碱玻璃纤维布进行增强而制成的一种管材。具有不燃烧、耐腐蚀、强度高和重量轻等特点，被广泛应用于宾馆、饭店、大型商场、写字楼的空调工程以及矿井通风、工厂排烟、除尘等工程。在建筑工程、地下工程及工业厂房的通风中，它已经完全取代了不耐燃的有机玻璃钢通风管，并在逐步取代防腐性能差的镀锌铁皮通风管。尤其是在湿度大的地下工程和长江以南地区，它的优越性更为显著。
Inorganic fiberglass ventilation duct, also known as glass magnesium air duct, is a type of pipe made from modified magnesite cement as the binder, mixed with organic or inorganic fillers, and reinforced with medium alkali fiberglass cloth. It has the characteristics of non combustion, corrosion resistance, high strength, and light weight, and is widely used in the air conditioning engineering of hotels, restaurants, large shopping malls, office buildings, as well as mine ventilation, factory smoke exhaust, dust removal and other engineering. In the ventilation of construction projects, underground engineering, and industrial plants, it has completely replaced the non combustible organic fiberglass ventilation pipes and is gradually replacing the galvanized iron ventilation pipes with poor anti-corrosion performance. Especially in underground engineering with high humidity and areas south of the Yangtze River, its superiority is more significant.

根据国家建筑材料行业标准JC646-1996标准的规定，无机玻璃钢通风管道按用途分为P类管和D类管两种。P类管主要用于公共建筑、人防工程及一般需要安装通风及空调设施的工业厂房和矿井等，作通风管、排烟管和排尘管；D类管则主要用作住宅建筑的通风管、排油烟管。
According to the National Building Materials Industry Standard JC646-1996, inorganic fiberglass ventilation pipes are divided into two types based on their purpose: P-class pipes and D-class pipes. P-class pipes are mainly used in public buildings, civil air defense engineering, and industrial plants and mines that generally require ventilation and air conditioning facilities, serving as ventilation pipes, smoke exhaust pipes, and dust exhaust pipes; Class D pipes are mainly used as ventilation pipes and oil fume exhaust pipes in residential buildings.
