TI-ProBoard is a durable structural composite board specifically designed for tiling decks and balconies. TI-ProBoard is unaffected by expansion/contraction and other weather conditions and acts as a structural replacement for deck boards. TI-ProBoard attaches directly to deck joists and is ready-to-tile. It has a Commercial Floor rating in the Robinson Floor Test and is the only single-component product available for bringing the beauty and durability of tile to exterior decks and balconies. TI-ProBoard is recognized in the TCNA Handbook as a Structural Ribbed Self-supporting Board (SRSB).
It's available in a 1' x 8' and 12' board and is only 3/8" thick so transitioning from the interior to deck presents no issues with height. TI-ProBoard also provides the structural base for the ClearPath Curbless Shower system. ClearPath enables contractors the ability to install a barrier-free (curbless) shower pan directly on top of the floor joists without any modifications required to floor system.
