Stair Installation
TimberTech does not recommend installing planks 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 planks plus a 1/8” to
3/16” gap between planks.
• For gapping requirements, see page 3.
• Ensure there is at least one stringer for support in the middle of the stair span.
• Cortex Hidden Fastening System provides a alternative to visible face fasteners on
stair applications. See page 10 for application instructions, uses, and restrictions.
Terrain Collection must be used as a veneer in a
stair tread application. Please see figure to the right.
