Thermal insulation solutions that prevent the spread of fire to other parts of a building or structure.

Our fire wall penetration systems will prevent the immediate spread of fire and toxic fumes through multiple rooms while limiting the heat release from the fire. This will serve to protect piping and equipment from fire damage and help safeguard personnel.

Modern buildings are full of various services that travel through multiple rooms within a building. Electric cabling and plumbing pipes are few of the items that pass through walls as they travel through a building.

When a service passes through a rated wall, penetration firestop systems are installed to ensure the wall’s fire rating is maintained.

Fire wall penetration systems are passive fire protective systems that are mainly used to compartmentalize a fire and to keep it from spreading for a long enough period of time so that the building can be evacuated.

Certain insulation materials are inherently combustible and will contribute to the intensity of fires. Other insulation materials may be noncombustible in themselves, but they may produce toxic smoke.

In commercial and institutional buildings, fire and smoke spread are key issues. The insulation material that should be specified anywhere that fire and smoke are possible will be fire-safe in itself and provide fire protection for the insulated structures and equipment.

The insulation material will also minimize the heat transfer to the protected structure, which, in turn, will help to minimize damage resulting from an external fire.

Because it is all-glass and inherently noncombustible, FOAMGLAS® insulation will not add any fuel to the fire and will not produce any toxic fumes.

FOAMGLAS® insulation has been widely tested and is acceptable to use in multiple penetration fire stop systems including various wall and floor materials and the use of several fire stop sealants.

A FOAMGLAS® insulation fire stop system will prevent the immediate spread of fire and toxic fumes through multiple rooms while limiting the heat release from the fire. This will serve to protect piping and equipment from fire damage and help safeguard personnel.

Typical configurations for fire wall penetrations:

  • a layer of FOAMGLAS® cellular glass insulation shall be dry applied
  • joints shall be sealed with a PITTSEAL® sealant appropriate for the application
  • PC® Jacketing or cladding finish where required
