Firestop Caulk and sealants in the South Shore of Montreal

Passive Fire stopping systems play an important role in protecting commercial, industrial, residential or institutional buildings: They can slow down or stop fire progression within a building and save lives. Calfeutrage Apex is one of the leading fire caulking companies on the south shore, and in this article, we will cover everything you need. We should know about firestopping sealants and their role within a firestopping system. 

What is a firestop caulk:

Firestopping caulk and sealants are sealing materials that resist the spread of fire and are installed in horizontal and vertical fire resistance walls, floors, and ceilings.

The use of firestopping sealants (also referred to as fire mastic sealant).

Firestopping sealants and caulk are designed to impede and/or prevent the spread of smoke, flames, and toxic fumes through gaps, holes, joints, and small openings in a building’s horizontal and vertical penetrations within fire resistance walls and floors. 

Compartmentalization – Passive fire protection

The choice of materials contained in the structure, as well as the type of structure constructed, can have an impact on the speed a fire spreads within a building.

By designing a building separated by fire-resistant walls and floors-Compartmentalization, protection is set against fire before it breaks out and is called passive fire protection. By compartmentalizing the building, you’re slowing the spread of smoke and fire through barriers.

Why are firestopping sealants necessary?

For the barriers (Barriers: such as walls, partitions and floors, that separate building spaces) to be effective, doors, windows, pipes, electrical channels, ducts, etc, must be fire resistant as well as any openings, holes, gaps and other small penetrations. 

 It can take seconds for a fire to spread through a hole as small as a pen nib, and therefore, it is crucial to install firestopping caulks to seal every opening.

If the fire is contained within a compartment:

  • People can evacuate the building safely.
  • The spread of flames once a fire begins will be limited or delayed.
  • The risk of loss of property is Minimized.
  • The tenants located in different parts of the building may be protected.
  • It helps the efforts of extinguishing the fire.
  • Fire department personnel may enter the building in time.


What are fire doors?
