Foam advantages:

  • Seals joints of rectangular ventilation ducts

  • Smooths away unevenness

  • Damps vibrations

  • Resistant to:
    - ageing
    - chemical impacts
    - reactions with organic substances

  • Thermal resistance: -40 °C to +90 °C

  • Easy and quick installation, place of application remains clean due to the lack of a paper interlayer.

Application:

The tape seals contact points between rectangular ventilation ducts and fittings. It effectively damps vibrations resulting from high wind loads.
