Our underlay helped the University of West Oahu extend the life of its zinc roofs, solving the problem of corrosion and high cooling costs.
Zinc roofs on five buildings at the University of West Oahu in Hawaii were corroding, and unlikely to last their 100-year design lifespan. The university sought a roof system with ventilation to reduce the condensation that gets trapped behind the zinc panels, speeding up corrosion. It also needed to cut cooling costs.
Our Enkamat ASV 7010 material is ideal for zinc roofs, because it prevents white rust caused by condensation. And by creating an airspace of less than ¾ of an inch, it lowers the roof temperature from between 22°C and 43°C. The three-dimensional nylon matrix structure is made from fused, entangled filaments – with 95% open matting. This provides continuous air and water flow, so there is less chance of damage caused by corrosion, rot, mould and mildew.
