For use under architectural metals, shingles or tile, Blueskin PE 200 HT high-temperature roof underlayment is made of a styrene butadiene styrene compound that has a high softening point.
It is also self-sealing when punctured by mechanical fasteners. Fully adhered systems prevent lateral moisture migration.
Other features include a slip-resistant surface and a heel puncture-resistant film. Its non-granular surface eliminates risk of damage to architectural metal finishes during application.
