RockwoolTM Promonta Acoustic Slab
- Rockwool Promonta Acoustic Slabs work in two distinctive ways to reduce noise, either by impeding the transmission of sound through an elopement of the structure or by absorption of sound at the surface.
- Noise absorption is expressed as a factor between 0 and 1.0. The more sound that a surface absorbs, the higher its absorption co-efficient.
- The Structure of the fibres in the 50mm Rockwool RW3 make them ideal for use as a sound absorber, with characteristically high co-efficients over a wide frequency range that enables the Promonta Gypsum wall to perform within this range which makes the system ideal for Party wall construction.
- The Rockwool Acoustic Slab is inserted between the two inner faces of the Gypsum Promonta blocks, the slabs must be held in position by means of an adhesive Element for structural acoustic stability and performance.
- The Sequence of installation must be followed in accordance with Euroform Products specifications. The Promonta wall is built following the usual installation procedure for Party wall construction, the primary leaf is built ensuring that all acoustic enclosures are in place. The Promonta Acoustic Slab is then adhered to the inner face of the proposed cavity using the Promonta adhesive. Care must be taken to ensure that the slabs are inserted with tight compression joints to avoid any sound weak spots. Once the inner face of the cavity is flanked with the slabs, the outer wall of the build may then be erected as before.
