Which materials might firestop putties be installed with?

Firestop putties are specifically designed to seal openings and joints in fire-rated walls, floors, and ceilings to prevent the spread of fire, smoke, and hot gases. The materials used alongside firestop putties are crucial for maintaining the fire-resistance rating of a construction element.

Ceramic fiber and rock wool filler are types of materials that provide excellent thermal insulation and fire protection. Ceramic fiber, in particular, can withstand high temperatures and does not combust, making it an ideal companion to firestop putties. Rock wool, also known as mineral wool, is made from natural or recycled materials that are treated to enhance their fire-resistance characteristics. These materials provide structural integrity within a firestop system and help to enhance its performance in case of a fire.

Using appropriate firestop materials is essential to ensure compliance with building codes and to maintain safety in the event of a fire, which is why the combination of firestop putties with ceramic fiber and rock wool fillers is recognized as effective in firestop applications.
