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! ~
