ALUMINIUM ROLL JACKETING
Insul-Global High Performance Aluminum Roll Jacketing is manufactured from 3003, 3105 Series Aluminum Alloys which is conforming to ASTM B 209 Standards. The product is cold-rolled to a half hard (H14 Temper) which provides additional strength to resist in probable misuse or handling during the installation or maintenance. The inner surface of the Aluminum is treated with a 3 mil PolySurlyn moisture retarder which prevents galvanic corrosion due to the dissimilar metal in the presence of moisture and also the chemical corrosion caused by installing over damp insulation materials. Also it has got excellent abrasion resistance during installation.
