Tech Talk – January 2018
By The CTEF Blog
This article is the first of three articles that examine, explore and explain the documents and publications essential to the health of our industry: The TCNA Handbook, the ANSI Standards and the NTCA Reference Manual.
If you spend time with anyone involved in the proper installation of ceramic tile, the TCNA Handbook for Ceramic, Glass, and Stone Tile Installation will be the focal point of the conversation. Why? Because this useful guide assists in clarifying and standardizing installation specifications for tile.
In addition to providing a selection of numbered installation “methods” for differentiating and easy reference, the Handbook includes various product selection guides for ceramic, glass, and stone tiles; guidelines for wet areas; field and installation requirements, and more.
Produced by the Tile Council of North America (TCNA), the TCNA Handbook for Ceramic, Glass, and Stone Tile Installation has been published on a continuous basis since 1963.
Here’s an overview:
First, what is the TCNA?
Tile Council of North America is a trade association representing manufacturers of ceramic tile, tile installation materials, tile equipment, raw materials, and other tile-related products. It was established in 1945 as the Tile Council of America (TCA). In 2003, it became TCNA reflecting how its membership has expanded to include all of North America.
Tile Council is recognized for its leadership role in facilitating the development of North American and international industry quality standards to benefit tile consumers.
Additionally, TCNA regularly conducts independent research and product testing, works with regulatory, trade, and other government agencies, offers professional training, and publishes industry-consensus guidelines and standards, economic reports, and promotional literature.
One of the highlights of the yearly Coverings show is hearing TCNA Executive Director Eric Astrachan review the state of the ceramic tile industry – from an economic perspective as well as from a creative and trend perspective in North America.
TCNA also strongly supports the mission of the Ceramic Tile Education Foundation.
What is the TCNA Handbook for Ceramic, Glass, and Stone Tile Installation?
The TCNA website describes the Handbook as follows:
“A guide to assist in clarifying and standardizing installation specifications for tile. Each installation recommendation, or method, requires a properly designed, constructed, and prepared substructure using materials and construction techniques that meet nationally recognized material and construction standards. Included are: product selection guides for ceramic, glass, and stone tiles; guidelines for wet areas; ISO mortar and grout specifications; information on substrate flatness requirements; information on grout joint sizes and patterns, and workmanship standards excerpted from ANSI installation standards.”
The TCNA Handbook provides installation methods from which to choose, based on the requirements of the installation or the types of applications in which they may be used.
For example, will the tile be installed inside or outside? In a wet area such as a shower or steam room? Or in a dry area such as an entry foyer? Each method includes a generic drawing that shows each component or material required as you can see in the image below, which addresses installing stone floor tile.
How is the Handbook organized?
In addition to detailing tile installation methods for ceramic and glass tile and natural stone tile, the Handbook includes:
- Product selection guides for ceramic tile, glass tile, natural stone tile, setting materials, grout, backer board, membrane, additional products and Green Building
- Field and installation requirements (i.e., substrate requirements, lighting, mortar and mortar coverage, flatness and lippage, grout joint size and pattern considerations, finished tilework, accessibility and wet areas guidelines)
- Floor tiling installation guide
- Environmental exposure classifications
- Using the TCNA Handbook for specification writing
- Installer and contractor qualifications guide
- EJ171 Movement Joint Guidelines for Ceramic, Glass and Stone
- Appendices and method locators
Each tile installation method details:
- Recommended uses
- Service rating
- Environmental exposure classifications
- Typical weight of tile installation
- Membrane options
- Materials (including for Green/Sustainable design)
- Preparation by other trades
- Movement joint requirements
- Installation specifications
The evolution of the TCNA Handbook
The Handbook is truly a living, breathing entity that evolves in lock-step with the tile industry. As new products get introduced – for example, new tile formats and new mortars and tools to support those formats – new installations methods quickly follow to ensure best practices.
As a result, the Handbook has increased in size. A press release detailing changes in the 2017 issue includes the following:
- The new sections “Tile Layout Considerations” and “System Modularity” are geared more toward those involved in tile selection and design. As an example of the various revisions to Handbook existing language, (Astrachan) noted the further explanation this year of substrate flatness requirements, which (he) calls “essential but too-often ignored.”
- A prime example is the new Handbook section to address the newer type of steel studs commonly referred to as “equivalent gauge” or “EQ” studs. The new Handbook language helps people understand the most important considerations for avoiding tile problems when these thinner studs are used. Stephanie Samulski, Handbook Committee Secretary and Technical Content Manager, noted that “the specific design criteria that are ultimately needed will likely get hashed out in ANS.”
- Other noteworthy changes that 2017 Handbook users will see include significantly more information on how to avoid the undesirable effects of wall-wash lighting on tile installations, new “Visual Inspection of Tilework” and “Design Considerations When Specifying Tile” sections, significant changes to the EJ171 movement joint guidelines, and a new method for tiling an exterior deck or balcony over unoccupied space (tile and stone versions).
What makes the Handbook unique?
The Handbook comes to life each year thanks to the Handbook Committee that includes representatives from the entire tile industry and all those touched by the tile industry – backer board, mortar, grout, membrane, tile and more manufacturers, industry associations, standards groups, construction specification groups and regional groups. It’s a balanced assembly of stakeholder voters that comes together to prioritize and address topics of concern.
The TCNA Handbook Committee determines Handbook content through significant group discussion and consensus efforts, and through meetings in person biennially and more frequently in workgroups.
As Astrachan explained, “The Handbook is a vehicle for providing industry consensus, but it’s not a standard and therefore not set up like one, enabling the committee to provide information in non-mandatory language when needed. It’s a particularly useful means of addressing conflicting recommendations or specifications, as can easily occur when a producer or another trade makes a major shift in product or practice in a way that impacts tile installations.”
Proposals for changes, often referred to as “submissions,” are welcome from any individual or organization.
