Paroc CORTEX ONE B is a windproof, non-combustible stone wool insulation slab. It is characterised by its windproof coating, with applications for existing and new tall buildings with well-ventilated external facades. It is used in a two-layer insulation system, in the outer layer, so that it cooperates with the main insulation layer, eliminating the occurrence of thermal bridges.
In addition, it is covered with a vapour-permeable and water-repellent layer, thus evaporating moisture quickly and effectively from inside the façade structure. The joints of the insulation boards should be additionally sealed with a special adhesive tape to prevent air flow between the boards.
