Joint Firestopping Systems

Professional Fire-Resistant Joint Sealing in Fargo, ND


Joint firestopping is an essential part of a building’s passive fire protection system. At Dakota Fire Stop, we specialize in installing fire-rated joint systems that help prevent the spread of fire and smoke through construction joints in walls, floors, and ceilings. Our team works with contractors and construction professionals throughout Fargo, North Dakota and the surrounding region to provide reliable fire protection solutions for commercial and industrial buildings.



When buildings are constructed, structural joints are designed to allow movement caused by temperature changes, building settlement, seismic activity, and other structural forces. While these joints are necessary for the building’s structural integrity, they can also create gaps that allow fire and smoke to travel from one area of the building to another. Properly installed joint firestopping systems seal these openings while still allowing the joint to move as designed.


Dakota Fire Stop installs tested fire-rated joint systems that help maintain the fire resistance of walls and floors while ensuring the building remains safe and code compliant.

What Is Joint Firestopping?

Joint firestopping refers to the installation of fire-resistant materials within construction joints to prevent the spread of fire and smoke between building compartments. These joints occur where two building assemblies meet, such as where a wall meets a floor or where two walls intersect.

Unlike penetration firestopping, which seals openings created by pipes or cables, joint firestopping is designed to protect the natural seams and movement joints built into the structure. These joints must remain flexible while still maintaining their fire rating during extreme heat conditions.


Fire-rated joint systems help:

  • Prevent flames and smoke from spreading between compartments
  • Maintain the fire rating of walls and floor assemblies
  • Allow structural movement while maintaining fire protection
  • Protect building occupants and property
  • Meet building code and fire safety requirements


Proper installation is critical because these systems must perform under high heat conditions while accommodating movement in the structure.

Types of Fire-Rated Joints We Install

Dakota Fire Stop installs firestop systems for many different types of construction joints found in commercial and industrial buildings.

Wall-to-Floor Joints

Wall-to-floor joints occur where vertical walls meet horizontal floor assemblies. These joints must be sealed to prevent fire from traveling vertically between floors of a building.



Properly installed firestop systems help maintain the fire resistance rating of the floor assembly and wall system.

Floor-to-Floor Joints

Floor joints occur in large building structures where expansion or movement joints are required in the flooring system. These joints must be protected to prevent fire and smoke from spreading between building compartments.



Dakota Fire Stop installs fire-rated materials designed to accommodate building movement while maintaining protection.

Wall-to-Wall Joints

Where two walls intersect or meet, joint firestopping is required to maintain the fire rating of both wall assemblies. These joints can be found in corridors, stairwells, and compartment walls throughout commercial buildings.



Our team installs tested joint systems designed to seal these intersections effectively.

Expansion Joints

Large commercial structures often require expansion joints to allow for structural movement caused by temperature changes and building settlement. These joints can run vertically or horizontally throughout the building.



Fire-rated expansion joint systems are designed to remain flexible while providing reliable fire protection during a fire event.

The Importance of Proper Joint Firestopping

Without proper joint firestopping, fire and smoke can spread quickly through gaps in building assemblies. Even small openings in walls or floors can allow dangerous gases and flames to travel between building compartments. Joint firestopping helps ensure that fire-rated assemblies perform as designed by sealing these vulnerable areas. This helps slow the spread of fire and provides additional time for occupants to evacuate the building safely. For building owners and contractors, properly installed joint firestopping is also necessary to meet building codes and pass safety inspections. Dakota Fire Stop understands the importance of installing these systems correctly and works carefully to ensure every joint system meets the required fire protection standards.

Firestop Materials Used for Joint Systems

Joint firestopping systems are installed using specialized fire-resistant materials designed to expand or resist heat during a fire. These materials are tested to maintain fire resistance ratings while allowing movement in the building structure.


Common joint firestop materials include:

  • Firestop sealants
  • Fire-rated joint compounds
  • Fire-resistant backer materials
  • Intumescent sealants
  • Fire-rated expansion joint systems
  • Mineral wool insulation combined with firestop sealants


Each system must be selected and installed based on the specific joint design, movement requirements, and fire rating required by the building.

Dakota Fire Stop carefully installs the appropriate system to ensure the joint performs properly in the event of a fire.
