Stone wool hollow cylinders used as thermal and sound insulation of technological piping and round air ducts
TECHNOCYLINDER is the non-flammable, water-repellent thermal and sound insulation hollow cylinders of mineral wool based on basalt rocks. These stone wool cylinders are used in industrial construction as thermal and sound insulation of technological piping and round air ducts. Applied at temperatures of insulated surfaces up to +680°С.
The cylinders have a continuous longitudinal cut on one side and a corresponding notch from the inside of the opposite side for easy installation on the pipe. Depending on the inner diameter and thickness, can also be produced in half-cylinders or segments.
