This pressure-moderated EIFS provides the benefits of a rainscreen, and also the option to have a continuous air barrier for the building envelope of any EIFS clad wall assembly. PUCCS was developed to make the design of rainscreen walls easy — both for the designer and for the contractor… The contiguously curved cavity of the system is formed within the insulation layer, thus providing both drainage and venting for pressure moderation. Regardless of how the insulation is installed, it will drain and vent as a true rainscreen. DuRock PUCCS is the most cost-effective exterior insulation rainscreen finish system available today!
