With the ability to withstand hurricane-force winds of up to 140 mph, COASTALUME™ offers peace of mind in regions prone to severe storms and harsh climates. Furthermore, it boasts fire-retardant properties and minimizes the risk of leaks and water damage. The product's resistance to chalk, fade, mold, mildew, salt spray, chemical corrosion and graffiti ensures longevity and maintains the aesthetic appeal of coastal structures. 

COASTALUME™ represents the next frontier in coastal building construction, addressing the unique challenges posed by coastal climates while prioritizing sustainability and resilience. COASTALUME™ provides a robust defense in storm-prone areas home and building owners would greatly benefit from over the material’s decades long lifespan.  

DuPont™ Tedlar® PVF film, introduced in 1960, has a proven track record of safeguarding surfaces in highly corrosive settings. In the American steel construction market, Tedlar® serves as a notable alternative to standard paint topcoat, offering a non-PFAS solution that gets the job done more effectively. Its benefits include exceptional resistance to color fade and chalking, even in areas that receive prolonged UV exposure.  

Additionally, Tedlar® showcases remarkable chemical resistance, effectively withstanding salt spray, acid rain and other corrosive materials found in coastal environments while remaining easy to clean. The durability of Tedlar® translates into warranties of up to 50 years without maintenance, surpassing those offered by traditional paint finishes, making COASTALUME™ the perfect solution for coastal property owners looking to protect their buildings for decades to come.
