Elk Wins Top Award for Quality and Service from David Weekley Homes

ElkCorp (NYSE:ELK) subsidiary Elk Premium Building
Products, Inc. (Elk), received the "Partners of Choice" double "A"
award for outstanding quality and service from David Weekley Homes
(Weekley), the nation's third largest privately held home builder.
   The double "A" distinction is the highest award given by the
Weekley team members in its National Trading Partners Survey.
Approximately 150 suppliers were rated, but only nine received the
"AA" distinction. Elk was the only roofing products company to achieve
this status this year.
   "Elk has demonstrated they are among the best of the best," said
David Weekley Homes Vice President of Supply Chain Services Bill
Justus. "This award is extremely difficult to earn because you are
evaluated by potentially 1,000 of our team members in all our markets,
and at all levels within our company. For a manufacturer, it requires
you to take ownership of the supply chain through the delivery and
installation of products into our homes. Elk's performance in this
survey proves our faith in our relationship is well-founded."
   The National Trading Partner Survey is sent quarterly to over 250
team members at every level in the Weekley organization (1,000
annually). Companies are rated on quality, service, product training
and supplier relations. Each company is assigned a numeric score
ranging from "A" to "F."
   "Through this evaluation process, David Weekley Homes clearly
demonstrates its high quality standard that is translated directly
from its supplier partners to the homeowner," said ElkCorp Senior Vice
President of Sales and Marketing Curt Barker. "Our customers know they
can have confidence in Elk to manufacture the highest quality products
sold by the highest quality people. We share this award with our sales
force, manufacturing plants and supply chain partners."
   Elk has maintained a strong relationship with Weekley for over
sixteen years and continues to be its largest supplier of roofing
materials.
