DuPont is committed to creating innovative materials that help builders and architects produce sustainable “green” buildings that cost less to operate, are easier to maintain and provide better comfort year round.
The U.S. Department of Energy reports that up to 40% of the cost of heating and cooling a building is wasted by uncontrolled air leakage. DuPont construction products work together to help seal the building envelope, reducing air leakage, while allowing moisture vapors to escape. This helps prevent the formation of mold and mildew for safer, more energy-efficient structures.
Keeping drafts and wind out of wall cavities seals in thermal performance for greater comfort and reduced energy consumption. DuPont™ Tyvek® weather-resistant barriers help protect the installed R-value of insulation, allowing the HVAC system to run more efficiently. Regardless of the thickness of the insulation or the type of sheathing used, including tongue-and-groove sheathing and airtight drywall, DuPont™ Tyvek® helps eliminate air leaks.
The fibrous structure of DuPont™ Tyvek® is specially engineered with microscopic pores that allow moisture vapors to escape the wall cavity, but are so small that bulk water and air cannot penetrate the building envelope. Better ventilation of wall cavities prevents the formation of mold and mildew, improving indoor air quality. Reducing the air flow from outside to inside also minimizes temperature differences for greater comfort.
DuPont™ Tyvek® reduces uncontrolled air leakage which allows for the optimization of HVAC systems. This improves the total life cycle of a building by providing operational system efficiency and protection from corrosion and mold growth.
DuPont™ Tyvek® weather-resistant barriers help protect building occupants and workers on the job site. DuPont™ Tyvek® is easy to install and requires no special protective apparel during installation. By reducing the potential for mold and mildew in the wall system you reduce the risk of occupant illness, increasing productivity and comfort level.
Sealing the building envelope with DuPont™ Tyvek® helps reduce the overall operating costs for a building, a powerful selling point for owners and potential buyers. In addition, protecting the wall cavities from bulk water prevents deterioration, increasing the asset value of the structure. Improved indoor air quality and increased insulation value provide a healthier, more comfortable environment.
DuPont™ Tyvek® construction products work together to help create a complete building envelope seal for more durable, energy efficient, healthy commercial buildings and homes.
“At DuPont we are proud of a decade of reducing our environmental footprint. We have come a long way, certainly in reductions of waste and emissions, but also in recognizing the impact of our operations on global issues such as climate change.
We define this direction as sustainable growth — the creation of shareholder and societal value while decreasing our environmental footprint along the value chains in which we operate."
- Chad Holliday, Chairman & CEO, DuPont
