Pipelines, manifolds, valves, tanks for heating or sanitary engineering and supply and return air ducts must be insulated to prevent heat loss in the latest energy-saving (EnEV) as well as the current state of the art. As an insulating material will generally be used mineral wool products in the form of slabs, sheets or trays and man-made fibers sector in the high temperature aluminum silicate (ceramic wool) in the area of application> 900 ° C. If you like it hotter, for which we have polycrystalline wool on offer. These are used at temperatures of 1300 ° C to 1600 ° C is used.

For the insulation as protective casing against mechanical damages, solar irradiation, and for moisture (rain) we utilize different materials.
