National Gypsum announces its newest innovation, Gold Bond BRAND XP Fire-Rated 5/16” Radius Wall, for radius applications requiring fire-rated assemblies. 

XP Fire-Rated 5/16” Radius Wall is used in double-layered construction. A one-hour UL tested assembly can be achieved with two layers, and a two-hour UL tested assembly can be achieved with four layers. 

“More creative design options become available by using XP Fire-Rated Radius Wall instead of traditional 5/8-inch gypsum board,” said Kelly Guinsler, Gypsum Product Manager for National Gypsum. “Designs can include convex and concave walls with a two-foot minimum radius. In addition, this gypsum board provides the best resistance to abrasion and mold in the industry compared to standard gypsum board products.” 

The special PURPLE® XP paper protects against mold, mildew and moisture, and is also abrasion-resistant. Combined with a denser core, XP Fire-Rated Radius Wall provides greater resistance to surface abuse when tested.

XP Fire-Rated 5/16” Radius Wall scores and snaps easily, with no special handling requirements. Tapered edges allow joints to be reinforced with ProForm® BRAND Joint Tape and concealed with ProForm BRAND Ready Mix or ProForm BRAND Quick SetTM Setting Compounds. For optimum resistance against mold and mildew, ProForm BRAND XP® Ready Mix is recommended for use.
