Stone mineral wool “Knauf FKD-S Thermal”

“Knauf FKD-S Thermal” is a compact slab of stone mineral wool with a uniform density, belonging to hard products. The product has very good thermal insulation characteristics – low coefficient of thermal conductivity, which provides excellent thermal protection of the building. “Knauf FKD-S Thermal” is non-combustible, resistant to high temperatures, water-repellent, resistant to aging, chemically neutral and highly vapor permeable. Its dimensions do not change with large temperature fluctuations. For easier work, the surface of each “Knauf FKD-S Thermal” plate is marked with two strips, which when laying the product must be on the installer’s side.

“Knauf FKD-S Thermal” is designed for heat and sound insulation and fire protection of an external wall in the ETICS system for single-family and multi-family residential buildings, as well as for the implementation of non-combustible fire protection strips.
