KIMMCO-ISOVER Duct Insulation (KDIP)

Product Application
KIMMCO-ISOVER Rigid Pipe Covering
KIMMCO-ISOVER Rigid Pipe Covering


  • KIMMCO-ISOVER Duct Insul Plus is manufactured from stable glass fibres bonded with thermo-setting resins, in the form of blankets, semi-rigid or rigid boards with factory applied Aluglass (Aluminium foil/glass fabric laminate) facing as vapour barrier.


  • Thermal and acoustic insulation (external) of HVAC equipment and air distribution duct systems.
  • KIMMCO-ISOVER Duct Insul Plus with Aluglass facing has added advantages:
  • by adopting advanced fabrication methods, the number of split-joints can be reduced, which ensures less number of thermal breaks and uniform R value throughout the surface area.
  • Aluminium foil laminated glass fabric (Aluglass) facing protects the system from normal mechanical abuses and stops vapour migration. So this system may not need additional vapour barrier.
  • By avoiding highly laborious and costly canvas/open mesh glass cloth and vapour barrier coating, KIMMCO-ISOVER Duct Insul Plus becomes more cost effective.
  • An ideal substitute for conventional thermal insulation practices.

Facing & Covering

  • Thermal insulation of heating, ventilation, and air conditioning (HVAC) ducting systems. Aluglass facing ensures zero water vapour permeability, puncture resistance, and eliminates the need for external weather protection.

  • WORKING TEMPERATURE: Fibres: up to 230 °C; facing: up to °100 C.
  • PERMANENCE: KIMMCO-ISOVER Duct insul plus has a high resistance to accident damage from knocks and handling during installation and maintenance. Dimensionally stable under varying conditions of temperature and humidity, rot proof, odourless, non-hygroscopic and will not sustain vermin and fungus. Easy to clean.
  • THERMAL CONDUCTIVITY: The thermal conductivity of fibreglass insulation products remains same throughout its lifetime because it is manufactured from natural minerals which neither deteriorates nor decays.
