General Insulation slab

General insulation slab PAROC eXtra is made of non-combustible stone wool and used for thermal, sound and fire insulation applications, such as walls, attics and floors, in all kinds of buildings. The highly insulating general insulation slab is soft and rigid. The slab is easy to handle, cut and install for different kinds of applications. The insulation doesn't settle, shrink or loose its insulation properties during its lifetime. The greater density of the slab is not prone to convection so the thermal resistance of the product is maintained even during extremely cold winters.

Certification Number0809-CPR-1015 / VTT Expert Services Ltd, P.O. Box 1001, FI-02044 VTT, Finland, 18.12.2013
Designation CodeMW-EN13162-T2-DS(70,-)-WS-WL(P)-MU1

PAROC stone wool products are capable of withstanding high temperatures. The binder starts to evaporate when its temperature exceeds approximately 200°C. The insulating properties remain unchanged, but the compressive stress weakens. The softening temperature of stone wool products is over 1000°C.

Durability of Reaction to Fire Against Heat, Weathering, Ageing/DegradationThe fire performance of mineral wool does not deteriorate with time. The Euroclass classification of product is related to the organic content, which cannot increase with time.
Durability of Thermal Resistance Against Heat, Weathering, Ageing/DegradationThermal conductivity of mineral wool products does not change with time, experience has shown the fibre structure to be stable and the porosity contains no other gases than atmospheric air.
