Interlock Roofing Systems are exclusively protected for a lifetime by Alunar® embedded with TEFLON® surface protector for ultimate durability and protection.

Alunar® with TEFLON® is a multi-layered coating system designed to provide our lifetime metal roofing products with a coating unmatched for stain resistance, flexibility, and surface toughness. There are many other benefits associated with this combination including the fact that it offers exceptional resistance to moisture. This combination is unique in our industry.

Today’s TEFLON® surface protectors are designed to provide superior resistance to stains, moisture, and organic debris such as mold, mildew, leaves, and tree resin. TEFLON® was originally used in cookware to provide a durable, nonstick surface, under high heat conditions, and has been field proven for over 50 years. The TEFLON® surface protector, now embedded in the Alunar® coating process evolved from this. Telfon® is manufactured by DuPont, a global provider of science and technology products with annual revenues of 30 billion ($U.S). For more information please visit www.dupont.com.
