玻璃纤维复合风管复合玻璃棉板经刀具切割、粘合、密封胶带密封和加固而成。复合玻璃棉板的双护层为玻璃纤维布复合铝箔或内护层为玻璃棉板。玻璃棉板采用离心法形成的玻璃纤维加树脂胶经热压、固化成型。板的常规格：密度 70~75kg\m2, 厚度 25mm 。由于复合玻璃棉板夹层为多孔轻质材料、导热系数低，吸声系数大，因而玻纤复合风管具有良好的保温和消声性能；同时，风管具有材质轻、施工周期短、防火、防潮、无有害挥发物、外形美观、使用寿命长、造价低等特点。复合玻纤风管与镀锌钢板风管加保温比较，可节省工程费用 30% 以上，尚不包括节省的消场设备费用，是低、中压空调通风系统最为经济、适用的一种通风管道。
Glass fiber composite air duct composite glass wool board is cut, bonded, sealed and reinforced by sealing tape. The double protective layer of the composite glass wool board is glass fiber cloth, and the composite aluminum foil or the inner protective layer is glass wool board. Glass wool board is formed by centrifugation of glass fiber and resin glue, which is hot pressed and solidified. Normal specification of the board: density 70 ~ 75kg / m2, thickness 25mm. Because the composite glass wool board sandwich is porous light material, low thermal conductivity and high sound absorption coefficient, the glass fiber composite air duct has good heat preservation and sound attenuation performance; at the same time, the air duct has the characteristics of light material, short construction period, fire prevention, moisture-proof, no harmful volatiles, beautiful appearance, long service life and low cost. Compared with galvanized steel duct with thermal insulation, the composite glass fiber duct can save more than 30% of engineering cost, not including the cost of field elimination equipment. It is the most economical and applicable ventilation duct for low and medium pressure air conditioning and ventilation system.
