Emseal pick-resistant fire-rated expansion joint

Emseal Joint Systems launches the UL-certified two hour fire-rated expansion joint, Securityseal, which is also pick-resistant, sound-proof, and watertight.

Securityseal features a pick-resistant watertight seal which has a hardened tamper-resistant surface and is capable of 50 per cent movement.

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 per cent (50 per cent total), available in widths for gaps ranging from 1inch to 6inches.

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 suited to precast tilt-up as well as block and cast-in-place concrete construction.

Securityseal has been tested and certified by Underwriters Laboratories (UL) to the rigors of UL 2079.

As a single unit two hour fire-rated expansion joint it eliminates the need for additional fire stops at the joint gap, and eliminating the need for multiple products to perform the roles of sealing, bridging and fire-rating joints.

A single-sided installation of standard 4inch 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.

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.

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.

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 of Securityseal means 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.
