Product Description : glass mat panel for extended mold and moisture protection

PABCO GLASS Interior gypsum panels are ideal for interior commercial and residential applications where mold and moisture are a concern such as bathrooms, kitchens, laundry rooms and basements. Comprised of a mold and moisture-resistant gypsum core reinforced with glass fibers, the panel provides increased resistance to moisture and greater structural stability than paper-faced gypsum board. Ideal for pre-rock construction as the product performance will not be compromised when exposed to normal weather conditions for up to one year. Available in 5/8” Type X for fire-resistance rated applications and 1/2” regular panels for non-fire-resistance rated applications.
