Security-Designed Expansion System
2 and 3-Hour Fire-Rated Expansion Joint for Floors

SecuritySeal SSF is a pick-resistant, watertight, 2-hour fire-rated (SSF2) or 3-hour fire-rated (SSF3), expansion joint for horizontal locations requiring a hardened tamper-resistant surface. Floors such as those found in prisons, detention centers, medical and psychiatric hospitals, school facilities and day-care centers are some of the many venues where SecuritySeal SSF is the perfect choice. Floor joints which join with fire-rated walls in common rooms, mechanical rooms, and stairwells are typical locations of use.

The
SecuritySeal SSF system is comprised of fire-retardant-impregnated foam which is factory pre-coated on the bottom fire-facing side with an intumescent fire-proofing material. The upper wear-side receives a top coat of waterproof, tamper resistant polyurethane. The system is supplied compressed smaller than the width of the joint gap. The precompressed foam is installed into the joint against field applied epoxy.  A field-injected polyurethane sealant band seals the upper bellows to the substrate at the wear surface (the sealant bands are optional where exposure to water is not expected). Joins between each stick are executed using a field-applied polyurethane sealant at the bellows' edge of the join and intumescent caulking on the foam face.

SecuritySeal functions as a watertight primary seal with movement capabilities of +/- 25% (50% total) available in widths for gaps ranging from 1/2-inch to 4-inches (12mm - 100mm). It is designed to be used in both retrofit and new structural expansion joints and in all other openings in horizontal-plane applications

Secure Pick-Resistant Seal - The outer watertight layer is made of a hardened flexible polyurethane which resists deterioration and destruction from picking.

Fire-Rated - It has been tested and certified by Underwriters Laboratories (UL) to the rigors of UL 2079. As a single unit 2-hour or 3-hour fire-rated expansion joint it eliminates the need for additional fire stops at the joint gap thereby eliminating the need for multiple products to perform the roles of sealing, bridging and fire-rating joints
. ONLY FIRE-RATED EXPANSION JOINTS THAT HAVE BEEN UL 2079 TESTED AND CERTIFIED SHOULD BE USED IN A LIFE-SAFETY APPLICATION.

Where UL tested listings do not meet your specific project conditions ask EMSEAL for an engineered judgment

STC 62 / OITC 52 

Sound Suppression - The EMSHIELD line of products are manufactured to display superior sound attenuation characterics when installed in an expansion gap. A single-sided installation of standard 4-inch deep EMSHIELD fire-rated products yields a tested Sound Transmission Class rating of STC-62* in a STC 68 wall. It also receives an Outdoor-Indoor Transmission Class rating of OITC 52.

Watertight - All EMSEAL preformed-sealant expansion joint systems are manufactured to be "watertight by design". The acrylic-impregnated open-cell foam is factory pre-coated with water-resistant polyurethane which acts as the primary waterproof seal.

Non-Invasive Anchoring — There are no hard metal-to-substrate connections with SecuritySeal SSF such as embedded pins, anchors, screws, bolts or tracks, trays or rails, flanges or coverplates.

The system is locked to the joint faces by means of 1) the backpressure of the foam; 2) epoxy adhesive, and 3) the injected sealant bands at the joint face. This method of single-unit installation accommodates installation at later construction stages where access, positioning or the existing infrastructure may interfere.

Joint-Size Variation —SecuritySeal SSF features the ability to handle variations in joint size through size-switching.

Energy Efficiency -- EMSEAL's foam technology also acts as an efficient air and thermal barrier. This means that indoor air quality and HVAC balance can be controlled while insulating the interior space from hot and cold exterior conditions. The non-metallic, non-invasive anchoring means that with SecuritySeal there are no thermal breaks introduced at structural or other joint openings.  

For joints from 1/2 to 4-inches (12-100mm) where +25% and -25% (total 50%) of nominal material size joint movement is expected.


Twice the Movement of Pick-Resistant Liquid Sealants

Liquid sealants offered for security applications achieve their tamper resistance primarily  from their hardness. Hardness restricts movement. In general pick resistant liquid sealants in traditional "caulk and backer rod" configuration have movement capability of +/- 12.5% or 25% total.

Because of the bellows configuration of SecuritySeal, the tamper-resistant polyurethane sealant is not stretched or compressed as in typical field-applied installations. Instead, the bellows folds and unfolds with joint movement. This results in the ability to offer a full 50% total movement capability thereby extending the use of tamper-resistant sealant technology to structural movement joints or other building component connections exposed to temperature changes.


Life-Safety Construction

Behind the pick-resistant outer surface is a fire-retardant-impregnated foam which is factory pre-coated on the bottom "fire-side" with a red intumescent coating. The resulting composite is then factory compressed to less than its nominal size for installation into structural or other openings. 

EMSHIELD SecuritySeal provides a pick-resistant, watertight, clean handling, UV stable, non-staining, low-temperature-flexible, high-temperature-stable, watertight, energy-efficient and fire-rated joint seal in a single installation process.


Product Description
EMSHIELD SecuritySeal features a wear-sided polyurethane sealing surface adhered to a fire-retardant impregnated foam backing. The bottom "fire-side" is coated with intumescent bellows.

The polyurethane face of EMSHIELD SecuritySeal is available in a choice of Tru-White or Limestone.

The system can also be custom specified to have a polyurethane top-coat over intumescent bellows on both top and bottom. The matches the design of
SSW2 for and walls.


 

The system is installed into epoxy adhesive field-applied to the joint faces.  A field-injected polyurethane sealant band seals the bellows to the substrate. Joins between each stick are executed using a field-applied polyurethane sealant band at the join and an intumescent sealant coating over the remaining foam at the adjoining faces.

Factory-Fabricated Transition
s— as in all EMSEAL expansion joint systems, continuity of seal through changes in plane and direction is an essential performance differentiator.

EMSHIELD SecuritySeal is manufactured in straight-run sticks which can be joined in the field to EMSEAL’s patent-pending SecuritySeal "Universal-90" Transitions .


Universal-90 Upturn Transition

Universal-90 Flipped-Over as Downturn Transition

These factory-fabricated single-piece 90-degree units have a 6-inch long leg and a 12-inch vertical piece on each end of the elbow.  Custom-90's are also offered with varying leg lengths manufactured for specific installations. Universal-90's are symmetrically coated on both sides.  This allows them to be installed as an upturn or as a downturn.  Either leg can be trimmed in the field to connect to straight run material or to another Universal-90 when going, for example, up and over a curb, into a parapet, or up and down treads and risers.

In addition to guaranteeing a continuous waterproof coating, and continuity in the fire barrier, EMSEAL’s "Universal-90's" allow for much faster and secure installation by eliminating field cutting or notching and bending at angles.

Testing and Standards

Only UL 2079 tests expansion joint movement (cycling expansion and contraction) during fire-rating testing. This is crucial because expansion joints move. Non-UL tests do not combine movement cycling and fire blocking --- therefore do not adequately test the integrity of the expansion joint in simulated real world conditions. Demand UL/ULC UL 2079 testing and certification in any life-safety application where an expansion joint needs to be fire-rated.

SecuritySeal has been tested and certified under UL 2079. UL 2079, like ASTM E1966, was developed to encompass the fire testing of ASTM E119 and the movement cycling regime
of ASTM E1399.

EMSEAL’s EMSHIELD SSF2 has been tested in accordance with UL 2079 in the configuration depicted in UL Systems: #WW-D-0077 and #WW-D-1089.
EMSEAL’s EMSHIELD SSF3 has been tested in accordance with UL 2079 in the configuration depicted in UL Systems: #WW-D-0076 and #WW-D-1088.


SecuritySeal meets the requirements of ASTM E1966, ASTM E119 and ASTM E1399.

EMSHIELD products have been tested and meet the air leakage requirements of ASTM E283, the water penetration requirements of ASTM E331, and the air pressure maintenance requirements of ASTM E330 all at greater than hurricane force winds tested with the foam expanded to its maximum expanded size.

Design/System/Construction/Assembly Usage

This material has been tested to UL/ULC 2079 and is manufactured under UL’s Follow-Up Service. The material is being supplied as a fire-rated component of a wall or floor assembly. It has been tested to UL 2079 in assemblies as depicted in EMSEAL’s various listings in the UL Online Certifications Directory. Use of this material in assembly configurations other than depicted in the named UL listings will not encumber or lower the resistance of the deck or wall assembly but is done so at the designers’ discretion and responsibility for designing substrates as part of a fire rated assembly that meet applicable standards for the project. Similarly, the published information in the UL Listings cannot always address every construction nuance encountered in the field. Authorities Having Jurisdiction should be consulted in all cases as to the particular requirements covering the installation and use of UL Listed or Classified products or materials. Authorities Having Jurisdiction should be consulted before construction to ensure that specific adjacent substrates and assemblies are detailed and constructed to meet local fire-rating requirements.
