Polysurlyn moisture retarder aluminum roll jacketing

Signi Aluminum’s polysurlyn mosture retarder aluminum roll jacketing, which is a three-layer, 3mil thick factory heat laminated polyfilm mosture barrier, instead of polykraft for all metal jacketing sheets, rolls and elbows.
 
It is simple, low cost and effective resistance to aluminum roll jacketing and pipe corrosion. Polyfilm is especially suited for service in which the underside of the aluminum jacketing may come in contact with excessive amounts of moisture for extended periods of time.
When water is present and touching the metal jacket, corrosion and does coour.This can happen in all applications(hot, cold, rooftop, industrial, commercial etc.) and with all insulation types.
 
Signi Aluminum’s polysurlyn mosture retarder has 3 layers of film: 1mil high-density polyethylene, 1 mil surlyn and 1 mil low-density polyethylene, with each layer carefully selected to yield optimum performance. Using such 3 layer 3 mil thick PFMB avoides the pinholes prevalent in the poor performing polykraft moisture barrier.
