HD Stone Wool Slab

Dryvit Stone Wool HD is manufactured from volcanic basalt rock that is heated to high temperature until molten and spun into a dense fiberous mat having a consistent through density. It is available as a Dryvit Square Edge Stone Wool HD Slab which exhibits very good insulating performance and is used for lamella fire break construction in Dryvit EPS systems.

Dryvit Stone Wool HD, when installed with the board fibres perpendicular to the substrate, is used to form lamella fire breaks in Dryvit’s Outsulation, Outsulation Rail and Drysulation External Wall Insulation (EWI) Systems.
