3-ply sarking and roof lining membrane, very high wear-resistance, high resistance to driving rain, very high thermal stability

 

Advantages

  • Highly permeable and at the same time, maximum resistance to driving rain, water column 10 000 mm (32' 10")
  • Optimum drying conditions for roof structures: non-porous TEEE functional membrane actively transports moisture outwards
  • Maximum ageing resistance and thermal stability thanks to the TEEE membrane
  • 4 months of outdoor exposure. Suitable for temporary roof coverings as specified in the ZVDH product data sheet
 

Application

3-ply highly permeable roof lining and sarking membrane which is suitable for laying on boarding, MDF and fibreboard roof lining panels and insulating mats and boards.
