Rendered facade slab PAROC Fatio Plus is non-combustible stone wool insulation for use as a base layer of thick rendered facade in existing and new buildings. The thickness of the rendering layers is above 25 mm, which creates an extremely strong and shock resistant facade for the building. The rendered facade insulation slab has excellent thermal insulation and alkali resistance properties. It doesn't accumulate moisture or react to changes in temperature. With rendered facade insulation slab you can easily create a smooth base layer for thick rendering in case of an uneven surface of the supporting wall. At the same time, you will improve the sound insulation and increase the fire safety of the external wall. Slabs are installed so that red marks are against the supporting wall and fixed with mechanical fasteners.
