Manufacturer of Flame Retardant Corrugated Ducts for Cold Aisles

Promat, Dura-Line, and Lindab are leading manufacturers of flame retardant and fire-rated corrugated ducts suitable for cold aisle applications.PromatPromat offers the PROMADUCT® system, a versatile fire-rated ductwork solution designed to protect critical services in buildings. Their ducts are fully tested for fire resistance, airtightness, and hygiene, making them suitable for ventilation and smoke extraction in sensitive environments such as data centers. PROMADUCT® uses PROMATECT® boards for reliable fire protection and is designed to meet complex building designs while maintaining sustainability through energy-efficient production processes .Dura-LineDura-Line manufactures plenum-rated, fire retardant corrugated ducts made from high-density polyethylene (HDPE). These ducts are low-smoke producing, fire resistant, and compliant with UL 2024/UL 910 (CSA FT-6) standards, making them ideal for cold aisle and cable protection applications. Their corrugated plenum ducts are designed for easy installation, future cable upgrades, and cold weather performance, providing mechanical resilience and fire safety in critical spaces .LindabLindab provides an uninsulated fire-rated duct system based on the Lindab Safe system. Their circular ducts are tested according to EN 1366-1 and classified under EN 13501-3, ensuring flames and fire are contained within the duct system. These ducts are suitable for environments requiring strict fire compartmentation, such as cold aisle containment in data centers, and must be installed following manufacturer guidelines for optimal performance .Additional OptionsOther industrial suppliers listed on DirectIndustry, such as Fitt, Brinner, and Sema, offer flame-retardant flexible and semi-rigid ducts made from PVC-coated polyester fabrics or E-glass ceramic cloth, suitable for ventilation and fume recovery applications. These products provide fire resistance, flexibility, and mechanical durability, which can be adapted for cold aisle airflow management .SummaryFor cold aisle applications requiring flame retardant corrugated ducts, the following manufacturers are recommended:Promat – PROMADUCT® fire-rated ductworkDura-Line – Plenum-rated HDPE corrugated ductsLindab – Fire-rated circular duct systemsOther industrial suppliers – Fitt, Brinner, Sema for flexible flame-retardant ducts These manufacturers provide certified, fire-resistant, and low-smoke ducting solutions suitable for data centers, industrial ventilation, and other critical airflow environments.
