Benjamin Obdyke’s HydroGap™ Drainable Housewrap Drains Moisture Two Times Faster Than Leading Drainable Housewraps on Market

Share Article

Introduced at Booth W842 at the IBS, HydroGap™ Drainable Housewrap – the only drainable housewrap with a 1 mm drainage gap – provides a superior combination of strength, water hold out, and vapor permeability. It removes 100 times more bulk water than standard housewrap, promoting proper moisture management in wall assemblies.

The launch of HydroGap is a huge step forward in the housewrap category and a major contribution to building sustainability.

Benjamin Obdyke introduced HydroGap™ Drainable Housewrap – now the construction market’s top-performing drainable housewrap – at the 2012 International Builders Show. HydroGap drains moisture from wall assemblies at least two times faster than the leading drainable housewrap and removes 100 times more bulk water than standard housewrap.

"The faster drainage and better performance of HydroGap mean less potential for mold and moisture damage in wall assemblies,” said Michael Coulton, Benjamin Obdyke General Manager. “Builders and contractors have trusted Benjamin Obdyke moisture management products to help them ‘build a better wall™’ for many years. The launch of HydroGap is a huge step forward in the housewrap category and a major contribution to building sustainability.”

HydroGap Drainable Housewrap combines a water-resistant barrier and drainage system into one application. Unlike typical housewraps which are either woven or non-woven materials comprising one or two layers, HydroGap comprises a tri-laminate substrate, with the moisture barrier protected between two non-woven layers. This composition creates a product with superior strength and water hold out vs. competitive products.

The patent-pending spacer design on the housewrap surface creates a 1 mm gap between the structure’s sheathing and cladding materials, thereby promoting drainage that is twice as fast as other drainable housewraps. The unique design also allows for the housewrap to be installed in any direction while maintaining its positive drainage capability. It provides excellent enhanced drainage around window sills, according to the manufacturer.

HydroGap has a number of features that benefit builders and contractors. Besides the potential of labor saving based on its omni-directional installation possibilities, the convenient 500-sq.-ft.-size rolls allow for easy one-man installation identical to standard housewrap installation. The low profile of the drainage space eliminates the need for design changes in the assembly. In addition, the easy-to-cut product requires no special tools for installation and does not need to be taped at the seams, further reducing cost and labor. HydroGap drains at 93%, meeting ASTM E2273, the standard test method for determining drainage efficiency of wall assemblies. It also exceeds AC38 for water-resistive barriers, including the new drainage provision. It is available nationally through a network of authorized distributors.

Benjamin Obdyke encourages construction professionals to reference its White Paper, Managing Moisture in Residential Building Envelopes, as a prescriptive guide for moisture management in different areas. Those building professionals who are in an area that dictates a need for a rainscreen for drainage and ventilation drying, the use of Benjamin Obdyke’s Home Slicker® family of rainscreen products is recommended.
