Rectified vs. Calibrated Tile: Which Sizing Is Best?
A 1/16-inch hairline grout line will show every defect in the subfloor. One of the first and most difficult decisions to make in high-end residential and commercial construction is whether to use rectified or calibrated dimensions. They both start as raw clay, and then get fired in a kiln and diverge. A working knowledge of the structural science of tile porcelain slab manufacturers , dimensional tolerances, and installation physics is required. Using an incorrect edge profile can extend your installation time, increase your costs, and cause finished lippage that cannot be undone. Rectified Tile: Mechanical Precision Engineering High-definition porcelain tiles undergo a post-firing, very abrasive mechanical grinding process. Tiles are cooled and hardened. Once cool, the edges of the tiles are ground by computer-controlled saws, trimming the four sides perfect square. Using the ANSI A137.1 (American National Standard Specifications for Ceramic Tile) and ASTM C499 test method...
