At last week’s Intex Expo in Nashville, National Gypsum introduced e2XP Extended Exposure Shaftliner. The shaftliner is the primary component of cavity shaftwall systems that are designed to enclose elevator shafts, stairwells and other vertical chases, as well as Area Separation Fire Walls in multi-family housing. The new product is a key component in the I Stud, C-T Stud and C-H Stud cavity shaftwall systems, as well as the H-Stud area separation firewall systems.

“National Gypsum has developed a new weather resistant alternative to traditional shaftliner panels that provides superior sound and fire resistant qualities,” said Jay Watt, director, sales and marketing.

The mold- and moisture-resistant shaftliner panel is made with a fire-resistant Type X core. It’s the next application of the company’s Gold Bond e2XP technology, which employs a coated fiberglass mat and enhanced core that can withstand up to 12 months of typical weather conditions. Like e2XP Sheathing, e2XP Shaftliner is produced in the signature purple color of National’s mold-resistant XP product family and is named for its capability to withstand extended exposure to the elements.

The product is specially coated on the front, back and edges for easy handling and scores and snaps to exact size without sawing. In addition, the lightweight panel’s long sides are double beveled for ease of installation.
