5/8 in x 4 ft x 12 ft National Gypsum Gold Bond BRAND eXP Interior Extreme AR Gypsum Panel


Gold Bond® BRAND eXP® Interior Extreme® AR Gypsum Panel is an abuse, moisture and mold resistant gypsum panel designed for interior applications requiring increased resistance to incidental moisture and surface abrasion.

eXP Interior Extreme AR is manufactured with an enhanced abuse, moisture and mold resistant gypsum core and facer. The facer is composed of a coated fiberglass mat which provides superior abrasion and moisture resistant capabilities. The specially formulated core provides greater abuse resistance to surface abrasion and indentation.  It is produced in a 5/8" thickness with a Fire-Shield® Type X core.  eXP Interior Extreme AR is easily identified by the back facer in National Gypsum's original PURPLE® color and the printing on the tapers.

Basic Uses

eXP Interior Extreme AR is designed for interior use in wall assemblies in areas where surface durability, indentation and moisture/mold/mildew resistance are major concerns.

Designed for use on the interior side of exterior walls, where moisture exposure is more likely.

Can be used for pre-rock applications before the building envelope is completely enclosed which may shorten construction cycles.

On projects where the owner or specifier has designated fiberglass faced gypsum board exclusively for the interior, the ideal solution is eXP Interior Extreme Panels.

  • Provides greater resistance to surface abuse and indentation over standard gypsum board.
  • Will withstand up to 12 months of interior exposure to the elements.

  • GREENGUARD listed as microbial-resistant when tested per ASTM D 6329.
  • Coated fiberglass mat on face and back for easy handling.
  • eXP Interior Extreme AR is an approved component in specific UL fire rated designs.
  • Less than 5% water absorption per ASTM C 473.
