Application Area

  • Before the boards are applied, duct surfaces to be used are cleaned to make sure the surface is free from dust and grease.
  • Special self adhesive fixing pins offer fast and easy application.
  • How the blankets are cut depends on the shape of the duct.
  • For the rectangular shaped duct system the blanket length to be cut should be determined as follows:
  • The external perimeter of the duct + (8 x blanket thickness) + 5 cm. For the cylindrical shaped duct system the blanket length to be cut should determined as follows: The external perimeter of the duct + (2 x blanket thickness) + 5 cm. The 5 cm flap provides the cover of the longitudinal joints after the Glass wool is removed from aluminium foil.
  • After the blankets are cut, special self adhesive pins are (5-6 pins per m2) fixed on the duct system.
  • Then the blankets are impaled over the pins.
  • Blankets are held in position by retaining washers.
  • The flap on the materials is then fixed by adhering, stapling or self adhesive aluminium foil tape.
