A Few J.L.E. Stories...

When 3M’s New York/New Jersey master distributor, General Insulation, has a difficult installation or application, they call J.L.E. Firestop, in the New York Metro Region.

At Cityspire, the tallest residential high-rise in New York City, J.L.E. was called in to firestop the curtain wall/edge of slab interface gap. Perimeter metal face plates, radiator covers and old insulation were all removed and replaced with compressed mineral wool; then, equipped with over 75 pails of 3M FireDam Spray, the J.L.E. team went to work.

“When they first started on the building, I had my reservations,” admits John Caricola, Cityspire facility manager, “especially since they were using a spray product in occupied space. But once I saw their attention to detail in protecting my carpeted floors, my fears were quickly calmed.”

The J.L.E. team used a spray method devised specially for use in occupied buildings. Using a water-tight transport system for the airless sprayer and spray product, it enabled workers to move quickly from floor to floor, installing FireDam Spray without spilling a drop. The product’s low odor formula and time-tested clean up procedures helped the team achieve installation in record time, according to J.L.E. owner Rich Jenkins, Jr.

The J.L.E. team was also involved in fire protecting a new 10-story dormitory in Bridgeport, CT. The challenge of this building was its lightweight fluted deck with 4” and 6” PVC riser penetrations. Before 3M developed the Ultra GS wrap strip, the normal method of firestopping PVC through a fluted deck was from the bottom side of the penetration. J.L.E. had to level out the flutes with the placement of a CS 195 composite sheet and then install a plastic pipe device (PPD) or job site fabricated device.

The need for this labor- and time-intensive method was all but eliminated with the advent of 3M’s innovative Ultra GS drop-in design (described in UL detail #FA 2045). By addressing the 4” and smaller PVC penetrations, it enabled installation time to be cut in half, allowing the time saved to be applied to working with the remaining 6” installations, which still required a custom fit.

After completion of this project and installations at MCl World Corn locations, Bill Hoos, Operations Vice President for J.L.E. proudly boasts, “I’d put my telecom mechanics up against anybody else out there, when it comes to cable tray or precision custom-cut CS 195 composite sheet work.”

With J.L.E.. General Insulation and 3M partnering in the New York Metro Region, the sky’s the limit for firestopping performance! ~
