Fire protection is a critical concern in the construction of new buildings or renovations, particularly for construction joint systems like head-of-wall, wall-to-wall, bottom-of-wall and perimeter joints.
3M construction joint systems help prevent and limit the devastating effects of fire. Regardless of the project, 3M offers affordable solutions and the expertise to match your passive fire protection needs.
3M’s Construction Joint System products are designed to accommodate various movements induced by thermal differentials, seismicity and wind loads. When properly installed, they provide 3–4-hour protection against the spread of fire, smoke and noxious gas. 3M also has a variety of firestopping products that can be used in static joint systems.
3M offers firestop barrier sealants used to help prevent the spread of fire, smoke, toxic fumes and moisture. For both joint and through-penetration applications, our products have a fire rating of up to 4 hours in tested and listed systems for construction joints.
