The Outer Layer

The 17 oz/yd² (576 g/m²) three-ply, vinyl-reinforced laminate outer shell is highly resistant to external abrasion, rips, and tears. The outer shell features mold and mildew inhibitors and is UV stabilized for protection against sun degradation.

The Insulation Layer

The inner insulation layer consists of a high-performance stitch-bonded polyester insulation material. Its lightweight design adds flexibility to the ducting while maintaining its insulating attributes and reducing cost.

The Inner Layer

The inner sleeve is made of VentaTex® 11-1812, an 11 oz/yd² (373 g/m²), high-strength, three-ply PVC fabric manufactured by ABC Industries, Inc. VentaTex® 11-1812, which is specially designed to eliminate delamination commonly found in other inner liners. It is constructed by compressing high-tenacity, high-density polyester yarn between PVC films. The inner layer also features mold and mildew inhibitors to increase duct longevity.
