GlasRoc® Tile Backer is used behind tiles on all interior walls in wet areas such as bathrooms, laundry rooms, utility rooms and kitchens. GlasRoc Tile Backer products consist of a specially formulated moisture-resistant core with engineered fiberglass facers. GlasRoc Tile Backer Type X provides the same moisture resistance as GlasRoc Tile Backer, plus it has a specially formulated core for use in fire resistance-rated designs. GlasRoc Tile Backer and GlasRoc Tile Backer Type X are available in a variety of sizes to meet various application requirements.


GlasRoc Tile Backer and GlasRoc Tile Backer Type X panels are used in interior wet areas, non-wet areas, high-humidity areas and are typically used as a substrate for adhering ceramic tiles to walls in bathrooms, in shower and tub enclosure walls, kitchens, laundry and utility rooms. They may be used for walls and ceilings, countertops, and as a wall backing for laminate-faced panels or fiberglass tub and shower units to provide impact, fire and sound resistance.
