  • As experts in testing, inspection and certification of building materials,

UL ensures proper installation of firestop systems.

  • Proper installation of these critical life safety systems

helps protect the building and its occupants should a fire occur

  • System components and installation procedures are critical to

those used by today’s contractors, and engaging with UL to complete the on‐site inspection enables us to leverage our extensive understanding of these life‐safety systems

  • The UL Firestop Inspection Service helps ensure the system

was installed in accordance with the system requirements

  • Working with UL delivers other benefits like:
  • Accurate and complete inspections
  • Fast response times and flexible scheduling
  • An independent, third party partner that is widely

recognized and accepted by Authorities Having Jurisdiction

For more information, contact Ruben Sandoval at Ruben.Sandoval@ul.com or 480.290.6987.

Onsite Firestop Inspection Service

  • The UL Qualified Firestop Contractor Program allows contractors to

demonstrate their commitment to properly installed firestop systems.

  • Firestop systems serve as critical safeguards
  • A contractor must properly select and install a firestop system
  • The building codes require these breaches be protected and

UL QFCP denotes contractors providing additional quality assurance UL Qualified Firestop Contractors have implemented a stringent quality management system. To obtain certification, a Qualified Firestop Contractor must:

  • 1. Employ at least one individual with firestop expertise
  • 2. Pass the UL Firestop Exam
  • 3. Maintain a management system evaluated through an annual audit

The benefits of working with a qualified contractor include increased confidence, easy identification of contractors, and superior installations.

For more information, contact Ruben Sandoval at Ruben.Sandoval@ul.com or 480.290.6987.

  • Let UL audit your site specific firestop installations to determine

conformance with our 10 Element Program Requirements. The MACC Program provides stakeholders the confidence that the firestop systems installation and maintenance of their building was completed by a UL Qualified Firestop Contractor and audited to our requirements. The easiest way to verify that your firestop installation and maintenance was completed by a UL Qualified Firestop Contractor and audited to our stringent 10 Element Program Requirements is through the MACC program. BENEFITS INCLUDE:

  • A jobsite‐specific management system audit and improved documentation
  • A renewable jobsite/annual assessment‐specific certificate
  • Annual assessments per the 2018 International Fire Code

If you’re interested in UL joining a pre‐construction meeting, contact Ruben Sandoval (below).

Expansion joint assemblies are installed on floors, walls, ceilings, roofs and exterior walls as well ad open air areas and plazas. They are designed to cover the gaps and continue the building design elements across them while allowing movement to occur. Aesthetics, Fire Rating, Sound Dampening and Waterproofing are critical design elements.

W hat is an Expansion Joint Assem bly required to do?

  • Move with the building
  • Conform with adjacent construction materials
  • Support the required traffic and elements
  • Provide Life Safety Elements
  • Last longer than just the warranty
  • Work with materials like Concrete, Gypsum…

Expansion Joint Terminology

  • Nominal (Static) Width
  • Minimum (Closed)

Width

  • Maximum (Opened)

Width

slide-15
SLIDE 15
  • Movement is the distance between maximum and

minimum joint widths and also acceleration

  • Expressed as either a numerical value or a percentage
  • f nominal width
  • Typically joint systems are described as:

+/- 25%, +/- 50%, +/- 100% Movement

Nominal = 2 inches Maximum = 3 inches Minimum = 1 inch

( 50% plus and minus model)

  • Two Methods:
  • Splicing Iron (preferred)
  • Cyanoacrylate Glue
  • Preheat the splicing iron to ~ 375 degrees F
  • Need two forms to hold the CS firmly in place
  • Cut ends of CS seal if necessary, to create two

flat ends

  • Place CS seals into forms, let the CS seal stick
  • ut slightly past the form
  • Press the ends of the seal onto splicing iron
  • When the edges of seal start to curl up,

remove from iron, align the two pieces and quickly bring them together

  • Use a flat tip solder gun to seal any gaps all

the way around the splice

Purpose of

Fire Barriers

  • IBC 715.3 ‐ fire‐resistant joint systems shall

be tested in accordance with the requirements of either ASTM E1966 or UL 2079

  • ASTM is a committee‐based standards
  • rganization comprised of volunteer

members from across the industry

  • UL (Underwriters Laboratories) is an

independent test lab that also develops test standards

slide-52
SLIDE 52
  • UL 2079 & ASTM E1966
  • Establishes the length of time

a joint system will contain a fire during a predetermined test exposure

  • F Rating – Time the system

contains flame

  • T Rating – Time cold face

temperatures remained below established points

slide-53
SLIDE 53
  • UL 2079 & ASTM E1966
  • Assembly is preconditioned by cycling to simulate

movement of expansion joint (ASTM E‐1399)

  • Class I 500 cycles

1 c/min.

  • Class II

500 cycles 10 c/min.

  • Class III

100 cycles 30 c/min.

  • Class IV

100 cycles 30 c/min. 400 cycles 10 c/ min.

  • Tested with a field splice
  • Wall systems are then subjected to hose stream
  • UL 2079 offers optional air leakage test (“L” rating)
  • An “L” rating is the cfm/lf of air able to penetrate the barrier at

ambient temperature and 400F
