White Fire Stop Caulking

Red Fire Stop Caulking


Abesco CP310 FR Acrylic Intumescent Caulk is designed to prevent the spread of fire from one compartment to another wherever services penetrate separating walls and floors, or wherever a gap remains between elements in fire rated walls or floors.

Abesco CP310 FR Acrylic Intumescent Caulk is a single part water based acrylic caulk, which provides a firm but flexible seal to joints in a variety of fire rated structures. It will not support combustion, and when exposed to fire it forms a carbonaceous char which expands to effectively seal any gaps, and prevents the spread of smoke and fire.

Abesco CP310 FR Acrylic Intumescent Caulk is supplied in a range of packaging sizes.


Here are some good design principles to think about when looking for firestop materials.

•All openings should be provided with a fire-stop that maintains the required integrity (fire rating) and/or insulation (t) of the fire wall or floor
• Insulation (temperature ratings) should be provided when combustible materials are located close to the wall of floor surface
• Fire-stops should be suitable for their intended use (fire & non-fire situations)
• Fire-stops should not affect the normal operation of building services/joint design
• Selected fire-stops should be tested or assessed to the relevant fire safety or building code



  1.  Prevent the passage of fire
  2. —Provide an effective smoke and toxic gas barrier
  3. —Water resistance seal
  4. —Retards transmission of heat
  5. —Lower insurance costs
  6. —Peace of mind
