Stair Installation
TwinFinish, ReliaBoard, DockSider, Earthwood Evolutions, and TwinRiser Boards:
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.
Place the TwinRiser board directly on top of the last
plank installed for the previous step to create the next step.
Repeat the process above.
Earthwood Evolutions Terrain must be used as a
veneer in a stair tread application. Please see figure
to the right.
