Glasswool

Glasswool

Mineral wool (rockwool or glasswool) is a fibrous material. Therefore, it has very good thermal insulation and sound absorption coefficients. The most important physical difference between rockwool and glasswool is the difference between their heat resistances.

The service temperature for rockwool is max. 750°C., but, this value for glasswool goes down to 250°C. Rockwool can thermally stand up to 1000°C. Rockwool is a preferred insulation material to use in buildings where noise or fire safety is an issue and needs to be resolved or in structures where combustible or flammable materials are stored. The fire resistibility of rockwool gets better when the insulation thickness is increased.

Mineral wool is cut and placed in panels in a fully automated production line,with fibers perpendicular to the panel surface in order to obtain a better compressive strength. Wool fiber cuts, which are sized to fit and fill the panel ribs, are placed in panels automatically with scattered joints.
