Overview
K-FLEX® K-FIRE BOARD consists of mineral wool batts pre-coated with a specialized fire-resistant protective layer. They are designed to firestop penetrations in walls and floors where pipes, cables, or other utilities pass through (service openings). The boards come in two options: single-sided coating (1-S) or double-sided coating (2-S). Before installation, the boards are cut to fit the exact size of the opening and the penetrating utilities, and then securely fixed into place. Depending on the fire rating requirements and the specific application, the boards are used in combination with K-FLEX® K-FIRE PIPE WRAPS. The K-FLEX® K-FIRE BOARD system is ideal for firestopping: • Cables and cable trays • Metallic pipes • Composite and plastic pipes (with or without thermal insulation) • Mixed services running through the same opening
