Trio extra


  • 4-layer, vapour-permeable sheathing membrane with microporous film and woven grid
  • Can be used in ventilated and unventilated roof assemblies as a trussing, sub-roof or sheathing membrane
  • Can be used as a rain-tight sub-roof on sheathing or a pressure-resistant underlay
  • Two vertically aligned, integrated self-adhesive strips ensure economical and lasting adhesion of longitudinal seams
