Water infiltration can compromise insulation effectiveness, but 100mm Full Fill Cavity Batts deliver a robust, water-resistant thermal solution ideal for new construction projects, cavity wall insulation upgrades, and building extensions.

Applications

100mm Rockwool Full Fill cavity wall insulation performs excellently in thermal insulation for external masonry cavity walls and delivers both thermal and acoustic benefits in masonry party walls separating residential units.

Approved by the British Board of Agrément (BBA) under Certificate 94/3079, this 100mm rockwool Full Fill product is certified for deployment across all exposure zones in domestic and non-domestic buildings up to 25m height.

The NHBC (National House Building Council) endorses 100mm Rockwool Cavity Batt for most applications, with the exception of highly exposed locations featuring fair-faced masonry finishes. Installation, use, and maintenance must follow the specifications detailed in BBA Certificate guidelines, in accordance with NHBC Standards, Chapter 6.1, External Masonry Walls.

Acoustic Performance

Stone wool's random fiber structure and density effectively absorb sound energy and reduce vibration transmission, delivering measurable noise reduction from external sources when integrated into external walls.

100mm Rockwool Full Fill insulation retains its dimensional stability and acoustic properties throughout the building's service life, guaranteeing reliable sound performance over decades.
