Ablative Coated Batt

Product

As part of the comprehensive FirePro range of fire protection products, the Rockwool Ablative Coated Batt is used to provide fire and acoustic barriers for voids created by the passage of services in both dry wall systems and masonry walls and floors. Such services include pipes made from steel, copper, PVC, ABS and HDPE together with sheathed cables supported on both trays and ladders. The Batts can also be used to from a blank seal, up to 1200mm x 600mm, in such wall and floor voids.

In response to this growing and increasingly important market, Rockwool has re-designed and tested the product to the dedicated fire resistance standard for penetration seals - prEN 1366-3. Due to its specific nature, this document is intended to supersede the traditional BS 476: Parts 20 and 22 previously used for fire seal testing in the UK construction market.

The tests have proved the capability of a single 60mm Batt to provide up to 4 hours fire resistance integrity and up to 2 hours insulation when used with all of the services listed above and also as a blank seal. Even for extreme requirements, where 4 hours integrity and insulation are required to maintain the performance of a masonry wall, a solution can also be accomplished with a double Batt solution.

Load-Bearing seals

FirePro Ablative Coated Batts are not intended for use as load-bearing seals. Where a load-bearing seal is required, Rockwool FireStop Compound should be considered.

Fire performance

Rockwool Coated Batt has been tested to the dedicated fire resistance standard for penetration seals - prEN 1366-3. The independently prepared assessment, detailing the full scope of fire performance, is available from the Rockwool Technical Sales Department. Ablative Coated batt fire resistance tests were conducted using Rockwool Acoustic Intumescent Sealant.

Acoustic Data
