Fire
Performance
Resistance
Solutions
Fire resistance refers to the ability of an assembly to serve as
a barrier to fire and to confine its spread from the originating
area. Spread of fire from one area to another occurs due to the
following conditions:
鈥? collapse of the barrier
鈥? openings in the barrier allow passage of flame or hot gases
鈥? sufficient heat is conducted through an assembly to exceed
specified temperature limitations
Performance Select CAN/ULC S101 or ASTM E-119 fire-tested assemblies to comply with regulatory
Requirements requirements, and construct the assembly according to specifications. If an assembly does
not comply, the building inspector may stop work or reject the job after completion.
Fire-Resistance A fire-resistance test rating denotes the length of time a given assembly can withstand fire and
Testing give protection from it under precisely controlled laboratory conditions. All tests are conducted
in accordance with CAN/ULC S101 or ASTM E119: Standard Test Methods for Fire Tests of
Building Construction and Materials. The standard is also known as ANSI/UL 263 and NFPA 251.
Fire resistance ratings are expressed in hours and apply to walls, floor-, roof-ceiling assemblies,
beams, and columns.
Design Substitutions For assemblies tested at Underwriters Laboratories Canada (ULC) or Underwriters Laboratories
and Additional Inc. (UL), ratings are specific to the designs tested. This is of particular importance when faced
Materials with alternate product or construction suggestions. For example, insulation may not be added to
floor- or roof-ceiling assemblies, unless described in the ULC/UL design. Addition of insulation in
the concealed space between the ceiling membrane and the floor or roof structure may reduce
the hourly rating of an assembly by causing premature disruption of the ceiling membrane
and/or higher temperatures on structural components under fire exposure conditions.

Sound
Performance
Control
Solutions
Sound control refers to the ability to attenuate or absorb sound
passing through a partition or ceiling assembly. Performance ratings
for sound control allow construction of wall and ceiling assemblies
that minimize sounds such as speech, music, mechanical equipment
or other sounds. Proper sound control techniques are a critical
component of effective living or working spaces.
Performance Performance depends on building design and careful attention to detailing and workmanship.
Requirements Penetrations, perimeter leaks, and other faulty design or installation practices can compromise
an assembly.
Sound Testing Sound control test ratings provide a comparison of sound in a space. For example, in an open
plan space, speech privacy is a major consideration. Partitions with a high STC (Sound
Transmission Class) can be used to minimize transmission of undesired sound space to
space. Ceiling systems with a high NRC (Noise Reduction Coefficient) can be used to absorb
and minimize undesired sound within a space. If the acoustical objective is to attenuate or
contain sound, ceiling panels with a high CAC (Ceiling Attenuation Class) are ideal. Sound tests
are conducted under ideal laboratory conditions per ASTM procedures. Use sound test data to
compare and select materials and constructions.
Design Substitutions CGC products are assembled in a specific manner to meet the requirements of these ASTM
procedures. Substitution of materials other than those tested or deviation from the specified
construction may negatively affect performance.

Moisture
Performance
Control
Solutions
Understanding moisture control and its impact on the construction
process and building materials is integral to good design and
construction practices. The best way to address moisture control
is to ensure that building materials do not get wet before and
during installation, and are not exposed to moisture inside the finished
building. In all situations, immediately identify and address the cause
of water damage to prevent re-occurrence of the problem.
Performance The key to minimizing moisture damage is controlling moisture, which must include consideration
Requirements of the building design, construction and maintenance practices. Select products and systems
that offer appropriate resistance to water and high-moisture conditions for your application.
Remember, products alone cannot control moisture or prevent moisture-related problems such
as mould.
Moisture, Mould and Testing provides a basis of comparative performance results. This does not mean that the test
Mildew Testing will accurately represent the moisture performance of building materials in actual end use.
CGC uses a variety of ASTM and other test methods to evaluate wet performance. These tests
evaluate characteristics such as water absorption, tile bond, and mould and mildew resistance.
CGC is actively working with experts to develop and enhance test protocols so that they
accurately represent specific product and system performance.

Abuse
Performance
Resistance
Solutions
Durability is one of the basic design considerations in
all buildings. Designers and their clients have realized
that it is often less expensive from a life-cycle perspective
to address abuse resistance in critical areas in the initial
project stage than to pay the high on-going costs of
maintaining and repairing regular partitions and ceiling
systems.
Performance Building design must consider the kinds of conditions that will exist and the resulting
Requirements stresses and movements. Abuse resistance may be defined as the ability of a system
to resist three levels of damage:
鈥? Surface or edge damage from abrasion and/or indentation
鈥? Penetration through to the wall cavity or ceiling from sharp or blunt impact
鈥? Security breach through the entire assembly from ballistics or forced entry
Abuse-Resistance Tests for abuse resistance provide comparative performance results versus alternative
Testing methods of construction. This comparison allows you to evaluate appropriate systems for
your application. CGC uses a variety of ASTM and other test methods to evaluate abuse
resistance. This gives you measures of abuse resistance based on surface damage from
abrasion or indentation; penetration (hard-body or soft-body resistance); and security
(forced entry or ballistic resistance) evaluated by the U.S. Department of State.

Aesthetics
Performance Solutions
A building鈥檚 aesthetics must strike a balance between form
and function. Influencing the aesthetics are the building鈥檚 end
use (retail, entertainment, education, etc.) and its environment.

solutions that meet design expectations.
Performance Determine the appropriate products and systems for the finished appearance of your interior
Requirements construction project, considering options such as textured or smooth finishes; drywall or
plaster systems; and a variety of ceiling system choices.
Levels of Finish Achieving top-quality finishing results under a wide range of circumstances demands proper
installation and application techniques. For critical lighting areas, start your research with the
