Description :

Emshield DFR2 is a UL-certified 2-hour fire-rated, watertight sound
suppressing, expansion joint.
Emshield DFR2 features a traffic-grade silicone sealing surface
on both the upper and lower faces, adhered to a fire-retardant
impregnated foam backing.
The system is installed into epoxy adhesive field-applied onto the
joint faces. A field-injected silicone sealant band seals the bellows
to the substrate at the traffic surface. (NOTE: DFR2 was tested and
passed UL 2079 without installation of sealant bands from the
underside and these are therefore NOT needed). Joins between
each stick are executed using a field-applied silicone sealant at the
top and bottom of the join and field-applied intumescent sealant on
the adjoining foam faces.
