SJS-FR features all of the performance advantages of the standard SJS System and adds the significant advancement of a built-in, UL-certified fire rating. SJS is comprised of silicone-and-impregnated-foam hybrid components that ensure watertightness, absorb sound, dampen vibration and offer uncomplicated installation.
Installed entirely from the deck surface, SJS-FR eliminates the complications of installing fire blankets from below the slab and is unencumbered by underslab mechanical and structural systems. SJS-FR is free of the complications of additionally lining fire blankets with gutters essential to keep the blanket dry and functional, and which then must be pitched and drained to plumbing to manage the water away.

Watertight — Emshield products are installed with the silicone bellows facing the weather to ensure watertightness. A field-applied sealant band of supplied silicone at the bellows to substrate interface seals substrate irregularities and completes the installation.
UL/ULC Fire-Rated — Tested in accordance with the cycling and fire endurance requirements of UL-2079, listed by UL, and manufactured under UL’s Follow Up Service ensuring that what is shipped is the same as what was tested.
Non-Invasive Anchoring — There are no hard metal-to-substrate connections with Emshield. This includes embedded pins, anchors, screws, bolts or tracks, trays or rails, flanges or coverplates. The system is locked to the joint faces by means of the 1) backpressure of the foam; 2) the epoxy adhesive, and 3) the injected sealant bands at the joint face.
Joint-Size Variation —through size-switching, material can be supplied to handle variations in joint size.
Sound Attenuation — Joints sealed with EMSEAL impregnated foam sealants offer exceptional acoustic dampening and feature STC/OITC sound transmission coefficients that can meet or exceed that of the assembly into which they are installed.
