doitBau® Ridge roll

Ridge roll


This ventilation roll for ridge and arris consists of a driving rain-proof polypropylene fabric and a corrugated aluminium strip down each edge. It has an outstanding tensile strength and is already provided with useful butyl adhesive strips for easy handling. Next to being sewed, the fabric is additionally fastened to the carrier material by hot glue making the seam extremely strong. This roll is particularly waterproof, due to the fabric’s minimal moisture absorption, and provides constant ventilation to the roof.

  • Waterproof
  • Vapour permeable
  • Weather resistant
  • Prevents snow, dirt and insect infiltration
