SecuritySeal by EMSEAL Brings Pick-Resistant Sealing and Fire Rating to Structural Joints
Pick Resistant, 2-Hour Fire Rated, Sound Blocking, Watertight, and 50% Movement -- One Product, One Install Does it All
EMSEAL Joint Systems, Ltd has just released their newest UL-certified 2-hour fire-rated expansion joint. SecuritySeal features a pick-resistant watertight seal which has a hardened tamper-resistant surface and is capable of 50% movement.
Institutional walls found in prisons, detention centers, medical and psychiatric hospitals, school facilities and day-care centers are some of the many structures for which SecuritySeal is the ideal choice.
SecuritySeal is comprised of fire-retardant-impregnated foam which is factory pre-coated on both outward facing sides with an intumescent fire-proofing material. Each side then receives a top coat of waterproof, tamper resistant polyurethane. A field-injected polyurethane sealant band seals the bellows to the substrate at the installation surface in weather-facing applications.
SecuritySeal functions as a watertight primary seal with movement capabilities of +/- 25% (50% total) available in widths for gaps ranging from 1-inch to 6-inches (25mm - 150mm). It is designed to be used in both retrofit and new structural expansion joints and in all other openings in vertical-plane applications. It is also uniquely suited to precast tilt-up as well as block and cast-in-place concrete construction.
In addition to its pick resistant outer surfaces, making it an obvious choice for areas of vandalism and security, it also has features which set it apart from traditional expansion joints.
Fire-Rated - SecuritySeal has been tested and certified by Underwriters Laboratories (UL) to the rigors of UL 2079. As a single unit 2-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.
Sound Suppressing - A single-sided installation of standard 4-inch SecuritySeal 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. (*for comparison purposes a dual-sheetrock US domestic wall averages an STC 33 rating; STC-62 is almost 90% quieter than such a wall. Even a high-density concrete wall will only range from STC40 to STC 50.)
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 such as embedded pins, anchors, screws, bolts or tracks, trays or rails, flanges or coverplates. There is no damage or compromise to the substrates, and because it is easier and quicker to install it can result in a significant cost-savings.
Energy Efficient -- 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.
SecuritySeal is part of the EMSHIELD line of products joining DFR2 for decks and floors and WFR2 for concrete and gypsum walls. The EMSHIELD family of products from EMSEAL are single products that meet all of the demands of the wall into which they are installed. Fire-rating, waterproofing, sound dampening, and thermal insulating expectations are restored at the joint in a single installation.
The EMSHIELD product line recognizes that building science is evolving; no longer are walls just separations between rooms. Expansion joints installed in walls are an integral part of the energy management, life-safety and indoor livability plans for the structure.
SecuritySeal is shipping and available for installations now. For more information about EMSEAL's EMSHIELD SecuritySeal or other products contact EMSEAL at techinfo@emseal.com or call 508-836-0280 / 800-526-8365 in North America, or visit the EMSEAL corporate website at www.emseal.com.
