Rock wool batts for interior wall is a semi-rigid stone wool insulation slab designed for superior thermal, acoustic, and fire performance in masonry cavity walls. Fully filling the cavity without the need for air gaps, it provides consistent insulation, enhanced energy efficiency, and excellent moisture resistance. It is suitable for internal partition walls, floors and ceilings of residential wooden and steel structures that require excellent fire resistance and acoustic performance.

Advantages

Delivers excellent thermal insulation with a low thermal conductivity of 0.037 W/m·K, helping to reduce heat loss and improve energy efficiency
Euroclass A1 non-combustible, providing the highest level of fire safety and peace of mind
Water-repellent yet breathable, allowing moisture vapour to pass through while preventing water ingress
Semi-rigid batts fit snugly between wall ties, ensuring a continuous insulation layer with minimal gaps
Provides effective acoustic absorption, reducing sound transmission through external and separating walls
Durable and dimensionally stable, maintaining performance throughout the lifetime of the building
Manufactured from natural volcanic rock and recycled materials, supporting sustainable and environmentally responsible construction

Applications

Interior partition wall insulation
Interior framed floor and ceiling assemblies
Designed for steel stud commercial construction
