Medium-weight underlay and sarking membrane



  • Flexible construction periods thanks to 4 months of outdoor exposure
  • Ensures reliable building components: highly diffusion-open and maximum rainproof protection against driving rain
  • Dry building components: pore-free TEEE functional membrane actively transports moisture to the outside
  • Permanent protection thanks to the high resistance to ageing and heat of the TEEE membrane
  • High degree of protection for building structures during the construction phase: suitable as a temporary covering


Diffusion-open underlay and sarking membrane for installation hanging freely across all the rafters or else on roof decking, MDF and wood fibre underlay panels and thermal insulating mats and boards.
