CT Series exterior wall and roof mineral wool boards are fireproof insulation materials mainly used in external thermal insulation plaster systems and dry curtain wall thermal insulation systems. They feature good compressive strength, tensile strength, and excellent water and moisture resistance, and are suitable for application on masonry, concrete, and other dense structural base walls.
Mineral wool boards can be used not only for the external thermal insulation of new buildings and extensions, but also for energy-saving renovation of existing buildings. With a Class A non-combustible fire rating and high resistance to high-temperature shrinkage, they can maintain the stability of the system structure in the event of fire.
