APPLICATION
Apply the
TECNOAIR rolls at the wooden support extrados, transversally to the ground slope, starting the installation from the eaves line, providing 20cm overlaps. The mechanical fixing can be effected by the use of large-headed nails or metal staples. On the top of the sheets must overhang on the opposite pitch to allow the overlaps. Even if
TECNOAIR is waterproofing, it’s recommended its protection with an upper waterproofing layer.
STORAGE
TECNOAIR should be stocked horizontal, on a clean and flat surface away from direct sunlight.
