Unlike typical housewraps that comprise one or two layers, HydroGap comprises a tri-laminate substrate, with the moisture barrier protected between two nonwoven layers for superior strength and water holdout, the company says. The product’s unique design allows it to be installed in any direction while maintaining its positive drainage capability. 800.346.7655. www.benjaminobdyke.com
