Description
Rockwool RW5 50mm (4 Slabs per Pack)
ROCKWOOL RW5 50mm is a high-density, semi-rigid stone wool insulation slab designed for acoustic, thermal and fire-performance applications in suitable building constructions.
With a nominal density of 100kg/m³, RW5 offers effective sound absorption, thermal insulation and Euroclass A1 non-combustible performance. It is suitable for specified walls, partitions, floors, ceilings and roof systems.
Where Can ROCKWOOL RW5 Be Used?
Walls & Partitions
Suitable for specified internal and separating wall constructions where acoustic absorption and thermal insulation are required.
Floors & Ceilings
Used in suitable intermediate floor and ceiling systems to contribute to acoustic and thermal performance.
High-Density Acoustic Insulation
The 100kg/m³ nominal density provides a higher-density option within the ROCKWOOL RW Slabs range, where RW5 is specified.
Thermal & Fire Performance
Stone wool insulation with published thermal conductivity of 0.034 W/mK and Euroclass A1 reaction-to-fire classification.

One Pack Covers 2.88m²
Each slab measures 1200 x 600mm, providing 0.72m² of coverage. With four slabs per pack, calculate your requirement by dividing the total installation area by 2.88 and rounding up.
Example: 10m² ÷ 2.88 = 3.47, so order 4 packs, before allowing for cutting waste.
