Fire Rated Sealants, Mastic & Mortar

Fire-rated sealants, mastics, and mortars are used to maintain the fire resistance level (FRL) of walls and floors where gaps or service penetrations occur.

• Mastic / Sealants – for linear joints, small gaps, and cable penetrations
• Mortar – for larger openings and rigid penetrations
• Foam – for irregular or hard-to-access gaps (where approved systems allow)
