Alco Shield™ Ice and Water Protector
August 8, 2001
ALCO-NVC Inc., Detroit, offers Alco Shield™ ice and water protector, now with an even stronger fiberglass reinforcement combined with the highest quality of modified asphalt. The membrane is used as a shingle underlayment to resist penetration of water due to ice dam backup or wind-driven rain. It also works to protect other leak-prone roof areas.
