Emseal SJS-FR1 1-hr fire-rated expansion joint, watertight, seismic and large-gap joint system for parking decks, car parks, stadiums, floors

With Sika Emseal SJS-FR1 -- Install Does It All--Fire-Rated, Watertight, Traffic Bearing, 100% Movement, Quiet, Non-Invasive Anchoring, UL 2079 Certified for Decks and Floors

• SJS-FR1 (1-hour rated) and SJS-FR2 (2-hour rated) are designed to provide a watertight, fire-rated, trafficable joint system in 4-inch (100mm) through 10-inch (250mm) joint openings, in decks including parking decks, stadium concourses, stadium treads and risers, and other horizontal plane applications in any structure.

• The SJS-FR SYSTEM features all of the performance advantages of the standard SJS SYSTEM and adds the significant advancement of a built-in, UL-certified fire rating.

• The SJS-FR SYSTEM is two horizontal fire-rated joints pre-assembled in parallel adjacent to an extruded composite spline. The spline is designed as the receptor for the attachment of traffic plates that bear vehicle and other loads.

• SJS-FR has been tested and certified by Underwriters Laboratories (UL/ULC), to the rigors of UL 2079 for both 1-hour (SJS-FR1) and 2-hour (SJS-FR2) fire-ratings.

• The silicone-and-impregnated-foam hybrid components act to anchor the system, ensure watertightness, absorb sound, and dampen vibration.

• Fire-retardant-impregnated foam is factory pre-coated on the underside with an intumescent fireproofing material. The traffic surface and the bottom both receive a watertight silicone outer coating. The resulting composite is then factory compressed to less than its nominal size for installation into structural or other openings.

• The factory-assembled spline, bellows, and foam, are shipped with factory-attached installation hanger-bars.

• Epoxy gel adhesive is field-applied to the faces of the joint opening.

• The sealing assembly is lowered into the joint gap where it self-expands into the epoxy adhesive.

• Consecutive lengths are joined through the field-application of manufacturer-supplied, low-modulus, high-movement silicone to the spline and intersecting bellows surfaces. The fire-retardant foam ends are coated with a full layer of intumescent sealant.

• Friction fit alignment pins prevent the joins from moving during silicone cure.

• A field-applied silicone sealant band is injected at the bellows to joint substrate interface to complete the waterproofing.

• The SJS-FR joint-sealing assembly installation hanger bars are removed sequentially as coverplates are lowered over the joint and screwed to the center spline, completing the installation.

Specify the SJS-FR SYSTEM to:
- Comply with life-safety requirements
- Eliminate leaks and handle traffic and point loads at large structural expansion joints
- Reduce noise
- Eliminate hard connections to concrete
- Prevent deterioration of concrete decks
- Reduce tenant complaints
- Reduce maintenance costs
