How does stone wool behave in high temperatures?
Stone wool is made from stone melted in temperatures over 1500 oC. It does not change during a new heating, with the exception in temperatures over 1000 oC, then the wool is deformed. Stone wool contains organic binder 1 – 4 % of weight. This binder will breakdown in temperatures over 150 oC. The breakdown products have a specific smell. Paroc does not recommend staying in the same room where an insulated application (like oven or fire place) is heated for the first time. When the smell is not detected, the breakdown products have disappeared and you can stay in the room.
