Fire-resistant wrap specifications are designated based on a combination of material type, thickness, density, and intended application; while different manufacturers may employ their own naming conventions, they generally adhere to established industry standards.
In terms of material form, common specifications fall into three main categories: board, blanket/roll, and composite. Board-type wraps are typically used for protecting flat or regular structures, such as steel beams and air ducts. Blanket or roll-type wraps offer greater flexibility, making them suitable for irregularly shaped structures like cables and piping. Composite-type wraps feature a base insulation layer supplemented by reinforcement layers-such as aluminum foil, fiberglass cloth, or metal mesh-and are designed for projects requiring superior fire protection performance.
Regarding key parameters, specifications usually indicate thickness (e.g., 10mm, 25mm, 50mm), density (e.g., 80kg/m³, 120kg/m³), and fire resistance ratings. For instance, with the same type of rock wool fire wrap, varying thicknesses can result in fire resistance limits ranging from one to three hours; consequently, thickness is often a primary factor in distinguishing between models.
Further classification is based on the type of component being protected, such as "fire wrap for steel structures," "cable fire wrap," or "pipe fire wrap." These designations reflect not only physical specifications but also intended application scenarios and performance standards. Therefore, selection should be based on a review of both design specifications and product test reports, rather than relying solely on a model number.
