Features & Benefits

• Suitable for multiple substrates including:
  • Solid walls and floors; flexible walls
  • Multi-service penetrations
  • Head of wall
  • Blank seals
  • Face-fixed applications
• Can provide fire resistance from a single thickness batt
• Suitable for sealing 20m long x 1.2m high voids at head of wall
• Suitable for large unframed voids up to 7.02m²
• Tested with dampers
• Tested as part of the Firepro suite of solutions
• Lightweight and simple to install
• Tested for air tightness, providing an additional smoke and acoustic seal

Performance

• Tests have proved the capability of a single 60mm Batt to provide up to 4 hours fire resistance Integrity and Insulation ratings which are dependent upon the service penetrations and void size. Where 2 hours integrity and insulation are required we recommend the use of our 50mm Ablative Coated Batt
• 50mm Ablative Coated Batt has been certified by UL and CE marked to EAD 350454-00-1104.

Acoustic Performance

Tested for head of wall:

• Rw= up to 52db (2 x Coated batts)
• Rw= up to 38db (1 x Coated batts)

The correct use of Coated batt within concealed cavities and voids will reduce the level of transmitted sound:

• Rw= up to 52 db (2 x Coated batts) - incorporating 48mm O/D PVC /15mm copper pipe penetrations
• Rw= up to 34 db (1x Coated batts) - incorporating 48mm O/D PVC /15mm copper pipe penetrations

Installation

• Please see Product Data Sheet and Installation Guide for detailed installation instructions.
• Make sure that the area within the aperture is clean of any debris and remove any dust from the edges
• Cut Batt to the size and shape required to fit the aperture ensuring that batt will make a tight fit with all edges of the aperture
• Cut rectangular holes from the coated batt to accommodate cable trays or ladders containing cables
• Cut the Coated Batt across its width at the mid-point of each rectangular hole to enable the Batt to be fitted into the aperture
• Apply Rockwool Acoustic Intumescent Sealant to all edges of the Batt ensuring that an even cover is achieved over
  the entire thickness of the Batt. This should include the outer edges of the Batt and the edges of the cuts made across the
  Batt to allow fitting into the aperture
• Insert the Batt into the aperture
• Apply a bead of Acoustic Intumescent Sealant approximately 15mm wide around the perimeter of the Batt
  ensuring that all gaps between the Batt and surrounding edges are fully filled
• Apply a bead of Acoustic Intumescent Sealant approximately 15mm wide where cables pass through the
  Batt. Ensure that the sealant fully enclosed each cable within the tray or ladder and that all gaps are fully filled.
  9. Repeat step 7 and 8 on the other side of the Batt
• For any areas of Batt where the coating has been damaged, repaint with the Ablative Coating. Ensure that there is no
  uncoated slab or bare mineral wool visible
• Batts are not intended for use as load-bearing seals. Where a load bearing seal is required, Rockwool Firestop Compound should be considered
• For seals over 1200mm x 1200mm Batt to Batt joints are to be fully coated with Firepro Glue
