Patent Pending. Above sheathing ventilaton provides a thermal break layer under metal roofing reducing heating and cooling costs, draining moisture and reducing sound. 
buildsoundcontrolmetalroofEnkamat 7010 / 7020 ASV is a nylon matrix used for drainage and ventilation in metal, protected membrane, and ballasted roofing applications. This product is used when a weather barrier membrane
has already been placed on the sheathing and a drainage and ventilation layer is needed. 
  • 95% open matrix provides unrestricted flow of water and air
  • Reduces rooftop temperatures at sheathing by 20%
  • Allows differential movement due to temperature change
  • Promotes evaporation of moisture out of the roofing structure
  • Lightweight and easy to get onto roof
  • Flexible and conformable to any surface
  • Cuts easily with scissors / utility knife
In addition to creating a cavity for a thermal break (increased energy efficiency), Enkamat also provides an acoustic break, reducing impact
noise (rainfall, hail, sleet) up to 50% - or 21dB.
