DuPont™ Tyvek® ThermaWrap™

Breathable air, water and thermal protection in one roll. 

DuPont™ Tyvek® ThermaWrap™ R5.0. The next revolution in weatherization technology - one breathable product for air, water and thermal protection.

DuPont Tyvek® ThermaWrap™ R5.0 offers the air and water management benefits of all DuPont Tyvek weather barriers with an R-value of 5.0. Compared to other exterior insulation products, the unique structure of Tyvek® ThermaWrap™ R5.0 allows any moisture that may get inside the wall to dry and escape to the outside, helping to prevent the accumulation of water in the wall, reducing the chance for water damage and mold.

Easy and familiar installation.

DuPont™ Tyvek® ThermaWrap™ R5.0 - like other Tyvek® weather barriers-can be installed  using familiar techniques and materials, including DuPont™ Flashing Systems products, Tyvek® Tape, Tyvek® Wrap Caps and DuPont™ Residential Sealant. Tyvek® ThermaWrap™ R5.0 is made with 6" uninsulated flaps  at the start and bottom of each roll, allowing all horizontal and vertical seams to be installed in a shingled fashion. This cannot be accomplished with rigid exterior insulation products and is an essential step to keep water and air out of the wall.

Reduce the risk of callbacks.

When installed properly, DuPont™ Tyvek® ThermaWrap™ R5.0 can help reduce the risk of callbacks because it is a breathable alternative to non-vapor permeable exterior insulation products. This means that if water enters the wall cavity, as it evaporates, the moisture vapor is able to escape back to the outside of the home, rather than accumulate in the wall. With other exterior insulations that are not vapor permeable or breathable, when water gets behind the insulation it is unable to dry effectively, potentially leading to mold and water damage.

You can be confident that with Tyvek® ThermaWrap™ R5.0, you are getting the optimal balance of air, water and thermal protection, as well as breathability, which is critical to high-performance walls and more energy-efficient, durable homes.

Tyvek® ThermaWrap™ R5.0 features/benefits at a glance:

  • Convenient, easy-to-handle 4' x 40' roll that allows for easier installation than rigid exterior insulation.

  • It breathes, allowing any water in the wall to dry and the moisture vapor to escape to the outside.

  • Provides continuous exterior insulation (CI), increasing the R-value of the wall while reducing thermal bridging.

  • Can be installed shingle fashion, reducing the potential for water infiltration and air leakage.

  • Windows, doors and penetrations can be easily flashed using available DuPont™ Flashing Systems products.

  • Made with 20% pre-consumer, recycled polyolefin.

  • Class A flame spread and smoke developed index rating with no added fire-retardant chemicals.

  • Energy savings and improved comfort for building occupants.

  • Significantly reduces Home Energy Rating Systems (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 condensationin heating climates.

  • Backed by a 10-year limited warranty.

  • Supported nationally by the DuPont™ Tyvek® Specialists Network and the DuPont™ Building Knowledge Center.
