Patent Pending. Above sheathing ventilaton provides a thermal break layer under metal roofing reducing heating and cooling costs, draining moisture and reducing sound. 
 
Enkamat 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.
