Firestop Training - Curtain Wall & Edge of Slab Joints (Part IV)

This field condition is dealt with in the section on Curtain Wall & Edge of Slab Joints in the AHJ Handbook for Firestop Inspection and in the 2nd edition of the Visual Field Guide to Firestop Assessment

Head of wall (HOW) joints constitute a much larger total area for smoke and heat migration than through penetrations. Also, the HOW joint is the first point of attack for rising smoke and heat in any fire. Despite this reality they seldom get the focus they require.

One of the most overlooked issues with curtain wall and edge of slab joints is the width of the joint. Each Firestop System or Engineering Judgment will detail exactly what the maximum width is. Systems that allow up to a maximum width of 6” are common. EJs are often required for joints wider than that.

Here you can see the embossed pattern on the surface of the wool after it was installed and the spray sealant was applied. When this pattern is visible, the mineral wool fibers are compressed in the wrong direction.

Firestop Training - Curtain Wall & Edge of Slab Joints (Part I)

Head of wall (HOW) joints constitute a much larger total area for smoke and heat migration than through penetrations. Also, the HOW joint is the first point of attack for rising smoke and heat in any fire. Despite this reality they seldom get the focus they require.

One of the most overlooked issues with curtain wall and edge of slab joints is the width of the joint. Each Firestop System or Engineering Judgment will detail exactly what the maximum width is. Systems that allow up to a maximum width of 6” are common. EJs are often required for joints wider than that.

Critical to the performance of edge of slab and curtain wall firestopping is the orientation of the mineral wool placed in the opening. Mineral wool has a very definite fiber orientation as seen here.  In joints, the mineral wool is required to be compressed to a certain ratio and must ALWAYS be compressed parallel to the fiber orientation

When mineral wool is compressed perpendicular, or against the fiber orientation, the fibers will fracture and its ability to provide a firm friction fit is severely compromised. The firestop system details will specify what compression ratio is required and will usually specify that the mineral wool be oriented with the fibers running parallel with the joint.

Firestop Training - Barrier Deficiencies (Part VI)

This item is section on Barrier deficiencies in VeriCon’s AHJ Firestop Inspection Handbook and the 2nd Edition of our Visual Field Guide to Firestop Assessment.

Using a hammer to make holes in GWB always creates a blowout on the back side. The firestop sealant may have functioned well in this opening but the barrier’s ability to limit heat transfer was seriously impaired. To get anything close to 2 hours of protection from this barrier it must be be repaired at the base layer and at the final layer

Firestop Training - Barrier Deficiencies (Part II)

With this field condition we have a combination of bad barrier construction and bad firestopping. The large gap in the drywall is barely covered with just drywall tape and extends in a Z shape for several feet in two directions.  Even if the opening for the MC cable was the correct size, the firestop sealant is just smeared on the surface of the wall. All firestop systems require sealant to be installed in the plane of the wall and completely fill the annular space. Just covering the surface of the opening is grossly inadequate.

Firestop Training - Shaft Walls and Stairwells (Part IV)

This field condition is dealt with in the in the section on Shaft Walls & Stairwells  in AHJ Handbook for Firestop Inspection and in the 2nd edition of the Visual Field Guide to Firestop Assessment

The head of wall and bottom of wall joints of elevator and mechanical shafts that terminate at each floor level must be firestopped. Smoke can accumulate in these shafts during a fire, bank downward, and be trapped in the shaft with enough pressure that it will flow out through these joints. An Engineering Judgment was needed for this application because of the untreated steel that was exposed at each floor on the inside of the shaft.
