June 12, 2006—DuPont and Alcoa have collaborated to develop a new product for the commercial building and construction market that provides protection against the damage of hurricane wind-borne debris.
DuPont and Alcoa are introducing a new product that incorporates both companies’ science and technical expertise in high-strength materials technology. Called Reynobond with Kevlar, it is a durable architectural panel system designed to withstand wind-borne debris and wind speeds common in hurricanes up to a Category 3 storm. (Category 3 hurricanes have wind speeds up to 130 mph.)
Reynobond made with Kevlar brand fiber acts as a safety net by helping to protect the facades of buildings from hurricane-propelled debris, frequently the main cause of hurricane damage.
Reynobond with Kevlar combines the weight and flexibility benefits of Alcoa’s Reynobond aluminum composite material with the impact-resistant strength of DuPont Kevlar fiber, the companies say.
By introducing a thin layer of fabric made from Kevlar fiber between the Reynobond aluminum skins and polyethylene core, Alcoa has created the only light, flexible aluminum composite material that can, on its own, withstand hurricane-propelled debris.
Reynobond with Kevlar is an ideal cladding material for the facades of commercial office and public buildings, such as schools, libraries, museums, hospitals and other small and mid-sized structures, particularly in hurricane-prone areas like the US Gulf region. It is a cost-effective alternative to traditional fascia materials because no protective backer material is needed, it is easy to install, and it is low maintenance, says Alcoa.
Panels can be shop-fabricated and quickly and simply installed onto studs, significantly reducing installation time and labor costs as compared to other facades. Because no repainting is required, the new product requires less maintenance over its lifetime.
Alcoa is the world’s leading producer and manager of primary aluminum, fabricated aluminum and alumina facilities, and is active in all major aspects of the industry. For more information, see the Alcoa Web site.
