Knauf Rocksilk RS45 Insulation Slab 100mm (3.60m2)

Knauf Rocksilk RS45 100mm is a high-performance insulation slab developed for applications where increased thermal resistance and sound absorption are required. The dense mineral wool structure provides effective acoustic insulation while also contributing to improved energy efficiency and fire protection within the building structure.

The 100mm thickness is suited to deeper cavity applications such as internal walls, separating partitions, and roof insulation between rafters. It is commonly used in situations where higher levels of soundproofing and heat retention are needed, including residential and commercial buildings.
