doitBau® dejett 100

Airtight vapour barrier

This tear resistant foil creates an inner airtight layer and effectively blocks water vapour. It is therefore ideally suited for all interior constructions and roof extensions. Because it prevents heat loss and keeps the insulation from getting soaked, it also works as a perfect moisture protection, e.g. for rafter rolls. Next to its various uses as a windproof sealing and moisture protection for all insulated constructions, it can be processed directly off the roll due to its special folding.

  • ƒUniversally applicable moisture protection layer
  • ƒƒTear and puncture resistant
  • ƒEasy laying
