Stair Installation
TimberTech does not recommend installing boards on steps without a riser board.
• Stairs should be constructed per local code requirements.
• Ensure the stringer step is at least the depth of two full boards plus a 1/8” to
3/16” gap between boards.
• For gapping requirements, see page 3.
• Ensure there is at least one stringer for support in the middle of the stair span.
• Stair landings and multi-level decks where there is a step down should use the
same structural support as required on stairs.
PRO Terrain, EDGE Prime and EDGE Prime+ must be
used as a veneer in a stair tread application. Please
see figure to the right.
