K-FLEX ST DUCT

Specially developed self-adhesive rubber insulation in rolls, reinforced with a mesh, designed for effective insulation of large surfaces in ventilation systems and large-diameter air ducts. Its unique properties can significantly reduce labor costs and installation time, which is critically important for large-scale HVAC projects.

Key advantages of K-FLEX ST DUCT for ventilation systems:

  • Exceptional speed and cost-effectiveness of installation: Thanks to the wide roll and strong self-adhesive base, material installation is extremely easy, fast, and does not require additional adhesive materials. This significantly reduces the time required for work and saves the project budget.
  • Reliable adhesion: The strong self-adhesive base with a reinforced mesh ensures optimal and long-lasting contact of the material with the metal surfaces of the air ducts.
  • Material usage optimization: The roll width of 1500 mm allows covering large areas with a minimum number of joints, which improves insulation quality and reduces waste.
  • Reduction of vibrations and noise: The high elasticity of the material helps absorb vibrations from ventilation equipment and airflow, which reduces the noise level in the system and ensures comfort in the room.
