1.1 This practice is intended to provide accepted installation procedures for thin brick units in adhered veneer systems in residential and commercial construction. This information is meant to complement the specific installation instructions provided by manufacturers of clay and shale thin brick adhered masonry veneers and recognized building codes but is not meant to replace them. Where this practice conflicts with the building code having jurisdiction, the building code having jurisdiction shall govern. This practice is limited to adhering thin brick units with mortar or other adhesives to a substrate that is designed and constructed by others or modular support systems where thin brick units are adhered with mortar or other adhesives to a substrate that is a part of the modular support system. Systems that rely solely on mechanical engagement with the thin brick units are outside the scope of this practice.
1.1.1 Neither the design nor construction of the substrate is the responsibility of the thin brick installer unless otherwise required by contract. Refer to the applicable building code and the contract documents for additional heat, air, and moisture control requirements. Should conflicts exist, the more stringent provisions apply.
Note 1: The Brick Industry Association (BIA) publication Technical Note 28C Thin Brick Veneer provides generally accepted methods and details for installation and flashing for thin brick veneer systems.
1.2 This practice covers the installation of thin brick units and related accessory items for exterior and interior adhered veneer vertical applications including walls, columns, landscape structures, and other structures suitable to receive adhered veneer. See 12.3 and 12.4 for limitations. This practice does not cover the installation of thin brick units embedded in concrete or installation with modular supports that rely solely on mechanical engagement with the thin brick unit.
1.3 The units included in this practice are manufactured to meet the requirements of Specification C1088.
Note 2: This practice was developed for the installation of thin brick units in adhered veneer systems. Refer to Practice C1780 for installation methods for cement-based adhered veneer units manufactured from wet-cast concrete or dry-cast concrete. Refer to Guide C1242 for installation methods of adhered natural stone veneer.
Note 3: The instructions in this practice are intended to be applicable to a variety of thin brick adhered veneer assemblies. Refer to the applicable building code or other relevant standards when the assembly must conform to specific performance characteristics, such as a fire resistance rating.
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.5 All material and workmanship requirements related to the installation of thin brick units should meet the more stringent provisions of the contract documents and the building code having jurisdiction over the project.
1.6 The text of this standard references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.
1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. (Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.2)
1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
