Are you familiar with the regulations regarding sleeves in residential buildings? We will introduce sleeves and flexible ducts that can be used in areas where non-combustible materials are required!
Fire-resistant and quasi-fire-resistant buildings, as well as sleeves for ventilation in quasi-fire-resistant specifications, require non-combustibility according to laws and related administrative regulations! The "Non-combustible Inclined Sleeve" is an external through sleeve made of highly corrosion-resistant galvanized steel plate, suitable for areas where non-combustibility is required. It can prevent the intrusion of fire into the wall structure. Additionally, it features a square flange, making installation and waterproofing treatment easy. Furthermore, by inclining the main body, it prevents water from entering the indoor side. We also offer other non-combustible certified products, such as the insulated spiral duct "Fuji Air Duct M" and the flexible duct with glass wool insulation "Fuji Flex." For regulations related to sleeves, please contact us! 【Features】 ■ Can be used in areas requiring non-combustibility ■ Prevents the intrusion of fire into the wall structure ■ Made of highly corrosion-resistant galvanized steel plate ■ Excellent corrosion resistance ■ Accurate and easy waterproofing treatment during installation
