This is the second in a series of blog posts on continuous building insulation in the context of soon to be forthcoming updates to New York building and construction standards coming out of Albany.

DuPont Tyvek R5.0 wrap provides a breathable air, water and thermal protection product designed to meet updated building codes and standards for continuous building insulation. The operative word here is “breathable,” thereby negating the need for air exchangers in other types of systems.

The Tyvek R5.0 systems, available from Secor Lumber, provides for air and water management benefits we normally associate with the Tyvek weather barrier systems, allowing moisture that may get inside the wall to dry and escape, and prevent accumulation of undesirable water in the wall, thereby greatly reducing the chance for mold and moisture damage.

Easy, Familiar Building Wrap Installation

DuPont’s Tyvek R5.0 product, like other weather barriers from this family of Dupont products, can be installed quickly and easily using familiar techniques, tools and materials, including DuPont flashing systems, tape, wrap caps and sealants.  The Tyvek R5.0 product is made with six-inch non-insulated flaps at the start and bottom of the roll, thereby allowing builders to install all vertical and horizontal seams in a shingled manner, an essential step in keeping air and water out of the interior wall cavities.

Features and Benefits of Tyvek R5.0 Building Wrap

  • According the DuPont’s product sheets, here are some of the notable features and benefits of the Tyvek R5.0 product:
  • Provides continuous exterior insulation (CI), increasing the R-value of the wall while reducing thermal bridging.
  • Replacement windows and doors and penetrations can be easily flashed using available DuPont Flashing Systems.
  • Significantly reduces Home Energy Rating System (HERS) scores in various climate zones.
  • Helps meet or exceed changing building and energy codes and standards.
  • Increases the sheathing temperature decreasing the chance for interstitial wall condensation in heating climates such as we experience in the upstate New York area.
