Product Information
Full details
The Rockwool Ablative Coated Batt is intended for contractors and construction professionals who need a reliable fire-stopping solution for wall and floor service penetrations. Its primary benefit is providing up to two hours of fire and acoustic protection, ensuring that service penetrations do not compromise the integrity of fire-rated compartments. A notable caveat is that while the material is moisture-resistant and robust, it requires precise cutting to ensure a snug fit around irregular penetrations to maintain its fire-stopping efficacy.

Do I need special tools to cut the slabs?
A standard sharp, serrated insulation knife is sufficient for cutting the slabs to size.

Troubleshooting
Difficulty achieving a tight fit around complex pipes.
Cut the batt into smaller segments to wrap around the pipes, ensuring each joint is tightly abutted and sealed with fire-rated sealant.
Slab is crumbling during the cutting process.
Ensure the use of a sharp, long-bladed insulation saw or a serrated knife to minimize mechanical stress on the stone-wool fibers.
Visible gaps between the slab and the wall perimeter.
Fill any remaining gaps with a compatible fire-rated intumescent sealant to maintain the fire-stopping integrity of the installation.
Pros and Cons

Setup, Compatibility & Care
To install, measure the service penetration opening accurately and cut the batt using a sharp, serrated blade for a clean edge. Ensure the batt is tightly friction-fitted into the aperture. For gaps between the services and the slab, use compatible fire-resistant mastic or sealant as specified by local building regulations. While the product is moisture-resistant, store in a cool, dry place off the ground until ready for use to prevent damage to the coating. Always wear appropriate personal protective equipment, including gloves and a mask, when cutting or fitting the material.
