DuPont™ Tyvek® Receives “A” Ratings for Outstanding Quality and Outstanding Service

WILMINGTON, Del. – DuPont Safety & Construction today announced it has once again received the Partners of Choice Award for an A rating in both quality and service from David Weekley Homes, the largest privately held U.S. homebuilder. Out of approximately 200 participating companies, DuPont™ Tyvek® was one of 18 recipients to receive an A rating in both quality and service. It is the seventh time DuPont™ Tyvek® has received this prestigious recognition.

“It’s an honor to receive our seventh Partners of Choice Award from David Weekley Homes,” said Alan Hubbell, residential marketing manager, DuPont Performance Building Solutions. “It’s especially rewarding to be recognized by an industry leader who shares our team’s commitment to delivering exceptional quality and working to exceed our customers’ expectations each and every day.”

The awards are based on David Weekley’s comprehensive supplier feedback platform that features its National Trading Partners Survey, a quarterly review of approximately 200 suppliers. A rigorous assessment is based on the builder’s unique supplier rating system by about 1,000 team members from every market and every level inside their organization. Beyond rating trading partners on quality and service, Weekley team members respond to specific questions on the challenges and preferences in managing business-to-business relationships.

“The Supplier Feedback Platform recognizes those companies that demonstrate, through the management of thousands of transactions over the year, that they are world class in delivering quality and service to our company,” said Bill Justus, vice president of Supply Chain Services for David Weekley Homes, and chief architect behind the nationally recognized Supplier Feedback Platform. It compares companies operating in different industries, with different challenges, and accepts the input from up and down our organization. There are no shortcuts to performing well in the process.”

The “Double A” Partners of Choice Award rankings result from strategic and efficient channel alignment. The accolade recognizes the concerted effort put forth throughout the year by the DuPont team to best meet the needs of its valued customer and partner, David Weekley Homes. DuPont™ Tyvek® provides building solutions that help make homes more beautiful, durable and energy-efficient by delivering dynamic science in a service-oriented manner.
