Siderise FR Retardant Acoustic Slab is a premium-grade insulation product engineered to provide exceptional acoustic performance combined with robust fire resistance. It is specially developed for use in internal partitions, floors, ceilings, and service areas where both sound control and fire safety are critical.
Constructed from dense, non-combustible mineral wool, the slab delivers high levels of sound absorption and thermal insulation. Its structure is designed to disrupt and dissipate sound waves, significantly reducing airborne noise transmission between rooms or floors. This makes it an ideal solution for spaces requiring enhanced acoustic privacy and comfort, such as offices, schools, hospitals, hotels, and multi-occupancy residential buildings.
A standout feature of the FR Acoustic Slab is its fire-retardant performance, which meets stringent building safety standards. It offers outstanding fire resistance, helping to slow the spread of flames and smoke in the event of a fire, and contributes to compartmentation within buildings—vital for protecting occupants and maintaining structural integrity.
The slabs are easy to handle, cut, and install, making them suitable for both new construction and retrofit projects. They retain their shape and performance over time, ensuring long-term reliability in demanding environments.
