Career Opportunities

MAUMEE, Ohio (November 27, 2006) – Therma-Tru Doors, the nation’s leading manufacturer and most preferred brand of fiberglass and steel exterior door systems, was named Supplier of the Year by Lowe's Companies, Inc. during the home improvement retailer's recent annual Vendor Forum. The award honors companies that meet or exceed Lowe's standards in innovation, product performance, environmental policies and responsive customer service, among other criteria.

Chosen from finalists in 20 product categories, Therma-Tru was the only supplier to achieve the top honor as Supplier of the Year. In addition to being named Lowe’s overall Supplier of the Year, Therma-Tru was also named the Lowe’s Millwork Supplier of the Year for the second consecutive year.

“We are truly honored to earn such a distinction from Lowe’s and be recognized among so many other world-class companies,” says Carl Hedlund, president and CEO of Therma-Tru. “It is part of our culture to listen to the voice of the customer and we’re proud that Lowe’s appreciates the efforts of our team. They have all worked extremely hard to earn Lowe’s trust and respect.”

In late 2004, Therma-Tru added Benchmark by Therma-Tru™ fiberglass door systems as a stock product in Lowe’s stores, along with a corresponding Therma-Tru & Benchmark by Therma-Tru special order kiosk. Informative consumer-oriented product brochures were created for both product lines, along with step-by-step point-of-purchase guides to further assist Lowe’s customers in selecting a door. New and unique display door signage was developed to provide consumers with further insight into the features and benefits of Therma-Tru fiberglass door systems. Therma-Tru also worked hand-in-hand with the Lowe’s training department to educate the sales staff on the benefits of fiberglass and attributes of the product lines.

Available exclusively at Lowe’s, Benchmark by Therma-Tru fiberglass entry doors provide proven durability and performance at a great value. These fiberglass doors are low maintenance, provide five times the insulating value of wood, and won’t rot or warp like wood, or dent and rust like steel. Available in wood-grain and smooth-surface, Benchmark by Therma-Tru fiberglass entry doors offer a broad variety of design options including embossed panel styling, decorative glass, and matching sidelites and transoms to complement any home.
