Made from three durable polypropylene components, DRYline HPX Commercial integrates a concealed microporous barrier that is thermally bonded between two UV stabilized, tough, and drainable non-woven fabric layers — one side white and the other side black. Each fabric surface withstands bumps and scrapes while gasketing fasteners and bonding with flashings, transition membranes, and sealants.


Performance & Reliability

HIGHER TEAR STRENGTH: Engineered specifically for demanding commercial construction jobsites, with over 2x the tearing resistance of the leading brand (ASTM D117).

EXCEPTIONAL AIR & WATER-RESISTANCE: Better than the leading commercial brand with 98% drainage efficiency on both surfaces (ASTM E2273).

RISK MANAGEMENT: Project based product liability insurance equal to the leading brand.

REVERSIBLE OPTION: Designed to handle extended exposure — 9 months on the white side and indefinitely on the black side when installed under open-joint cladding systems.

Support Sustainability Initiatives

DRYline HPX Commercial helps your project earn Energy and Atmosphere (EA) and Indoor Environmental Air Quality (EQ) LEED® points. Additionally, it satisfies the prerequisite for LEED applications requiring compliance with ASHRAE 90.1-2010. By effectively sealing the building envelope, DRYline HPX Commercial reduces energy consumption for heating and cooling. 

Part of an Efficient Building Envelope System

DRYline HPX Commercial can be seamlessly integrated with DRYline self-adhering flashings, seam tape and other transition membranes and sealants as part of DRYline’s limited product and system warranties. Reference for details.
