High-density stone wool or glass wool fibers, insulation material produced in the form of cylinders, are used in heating and cooling systems for thermal and sound insulation of pipes.

It is produced in a state covered with aluminum foil in order to increase its resistance to sunlight and prevent moisture and heat loss. The product is produced in different diameters so that it can be applied in pipes of different diameters. Cylinders should be used at different temperatures and at different thicknesses.
