Air-duct smoke sensors

Hi-Abuse XP wallboard uses a specially formulated core to provide greater resistance to surface indentation and impact. The panels help to reduce the potential for mold/mildew growth, compared with standard wallboard products, when used in conjunction with sound design and good handling and construction practices. Designed for use in all major construction areas, the product uses a fire-resistant gypsum core encased in heavy, smooth, abrasion-resistant, mold/mildew resistant, 100% recycled purple paper on the face side and heavy, mold/mildew-resistant liner paper on the back. The long edges of the panels are tapered to allow joints to be reinforced with joint tape and concealed with joint compound. The panels score and snap for quick installation and require no special handling or installation procedures.
