Tile contractors reached a major turning point this May, with code changes pushed by the International Masonry Institute (IMI) to make them more competitive with glass and other exterior finishes.
International Code Council’s (ICC) May hearings in Dallas, the IMI Code
Committee says it convinced the ICC to add new text to International Building
Code’s section on acceptable weather covering for building exteriors. [Table 1405.2, Exterior adhered
masonry veneers – porcelain tile.]
removes any ambiguity about tile’s proper place as an exterior finish. It will
take effect as areas adopt the 2012 I-Code, which will be available April 2011.
The new text
limits any porcelain tile face dimension to three square feet total, and less
than 9-lbs./sq. ft. Anything larger has to be mechanically anchored, which will
bring more reliable exterior tile installations by qualified contractors.
IMI's work on this issue,” said John Trendell, president of Tile Contractors'
Association of America (www.tcaainc.org). “It is certainly important for
architects and owners to understand the materials they have chosen for an
exterior installation. With the right materials and the high-quality
installation practices offered by our companies, architects and owners can be
assured of the best possible installation.”
