Case Study - ReVISION House Vegas
Product: Tyvek StuccoWrap; DuPont Roof Liner
Category: Weatherization Systems
Most of the strategies, technologies, materials, and design choices discussed in relationship to the ReVISION House Vegas focus on the energy-efficiency, or more broadly, the “sustainability” of the post-retrofit home. However, the true barometer of sustainability is measured by the ability to endure over time, thus the assuring the durability of whatever it is we value. It is with this in mind that the ReVISION project team selected DuPont Weatherization system products to provide the envelope moisture control for both the wall and roof systems. With over 25 years of residential performance on over 5 million homes, the DuPont™ Tyvek® line of protective membranes, breathable weather resistant barriers and flashing systems are the world’s leading weather protection products. The ReVISION House Vegas uses several of the Tyvek family of products in helping us reach our zero-energy goal, and do it for a long time!
Tyvek™ StuccoWrap® is a non-woven, breathable housewrap specifically designed and engineered for use below stucco surfaces. Its unique crimped surface texture provides a 3-dimension surface with continuous peaks and valleys assuring that a continuous drainage path is provided below whatever stucco surface is used for the final finish. Knowing that the finished stucco coat is only the first-line-of-defense and that a “weather-resistive-barrier” is also needed under the exterior finish, the project team chose StuccoWrap® for its ability to provide reliable redundant protection, and also because it is prescriptively indicated as a manufactured approved choice by Dryvit, for use below its exterior insulation finish system (EIFS), which was also used for the ReVISION House Vegas.
