Examples of ACBM
• Pipe coatings and coverings
• Spray-on and textured materials, including acoustics
• Textured paints, patching and joint compounds
• Shingles and siding
• Boiler/furnace insulation
5
Examples of ACBM
• Vinyl floor tiles, flooring sheets, and adhesive
• Building insulation
• Sealants and coatings
• Fireproof textiles and lab equipment
• Heat register tape and fuse box liners
• Gaskets
