Brandtätningsmassor

Brandtätningsmassor, also known as firestopping sealants, are specialized materials used to seal openings and gaps in fire-rated walls, floors, and ceilings. Their primary purpose is to prevent the spread of fire, smoke, and hot gases through these penetrations. When exposed to heat, many brandtätningsmassor expand significantly, creating a char layer that effectively seals the opening.

These materials are crucial components in maintaining the integrity of passive fire protection systems. By compartmentalizing a building, they slow down the spread of fire, giving occupants more time to evacuate and firefighters more time to respond. Common applications include sealing around pipes, cables, ducts, and structural joints that pass through fire-rated constructions.

Brandtätningsmassor come in various forms, including putties, sealants, collars, and wraps. The selection of the appropriate product depends on factors such as the type of penetration, the fire resistance rating required, and the environmental conditions. Proper installation is critical to ensure the effectiveness of the firestopping system. Building codes and regulations typically mandate the use of certified brandtätningsmassor and their correct application. Regular inspection and maintenance are also important to ensure long-term performance.
