How the right material selection helps you get to the root of warranty issues.


Imagine the first spring after your new development is sold is especially wet. Do the materials used in your construction include a high performance water-resistive barrier that can help you avoid warranty issues from water damage? “An estimated 70 percent of construction defects are related to moisture,” says Theresa Weston, Ph.D., a technology fellow in Building Science for DuPont.

“Rainwater enters walls at interfaces, where the wall meets the window or roof, where a deck ledge or support goes into a building — those are the main areas where water can potentially get in,” Weston says. “What’s important is not only preventing water from getting in, but whether you’re building a structure that is forgiving to water, and that manages water, and allows the structure to dry out.”

What’s the best way to produce quality, long-lasting homes that exceed consumers’ expectations and keep you from falling prey to the high cost of water-related issues?

The right product. The right way.

Product choice and installation must go hand in hand as your first line of defense. It’s “not just about materials,” Weston says. “It’s about the entire wall system. We provide flashing and water-resistive barrier systems along with proper installation instructions to ensure that it all works together.”

The best-in-class products offered by DuPontare backed by both science and support — giving builders the results they desire through product knowledge and installation consistency to minimize liability. The DuPont Building Knowledge Center offers building science support on a host of topics including proper installation, codes and standards, and technology issues. DuPontalso supports a broad network of Tyvek® Specialists across the nation who work closely with builders and installers to provide weatherization training and expertise.

Build better. Better built.

Building codes are becoming more stringent overall with rapid changes in the energy code in particular. “Since 2006, there has been a greater than 30 percent increase in energy efficiency requirements,” Weston says. “This requires homes to be built a little differently to meet the more stringent code.” Some builders may use more impermeable materials to improve energy efficiency. “In doing so you may be reducing [a structure’s] drying ability,” Weston says.

To be successful today, Weston believes builders need to build above code and choose products that are high performing to improve overall construction. For example, she says, sometimes framing wood will lay on a job site and get wet, and that moisture gets incorporated into the walls. Using a product such as “DuPontTyvek® allows for breathability and for drying,” she says. “Tyvek® weather barriers offer high performance air and water protection and have been tested and proven to perform above code requirements.”

No one wants to face a lawsuit, and it seems that partnering with a company that offers a comprehensive package of products, knowledge, and service is the way to stop issues before they happen. As Weston says, “The best liability defense is prevention.”
