Alternating direction
Achieve different looks by laying the decking in the same or 
alternating directions. There are several different wood grain 
patterns to provide a less repetitive and more natural wood 
appearance. The graining pattern repeats approximately every 44 
in. (1.12 m) along the board length. During the planning phase of 
any deck project, arrange decking before installation to achieve 
the desired pattern and color effect. This is also important if 
different lengths/bundles of material are used, as different wood 
grain patterns and color tones may need to be mixed to achieve 
the desired look.
All decking materials, whether wood, composite, or metal, undergo 
some degree of linear expansion with the changes of weather and 
the seasons. For best spacing results, keep boards out of direct sun 
during storage and cutting processes, and throughout installation 
if possible. Never cut and install boards in direct sunlight. To 
compensate for the effects of contraction and expansion, use short 
boards (where possible) with splitter/divider boards between each 
continuous run of boards. 
Adequate board spacing of a minimum 3/16 in. between board 
sides will provide proper drainage and ventilation and assist with the 
removal of small organic debris. Allow a minimum of 1/4 in. spacing 
between boards and any permanent structure. Spacing requirements 
must be met for full Fiberon warranty coverage.
Note: Special consideration should be taken when working with 
dark colors, as they will experience larger temperature swings during 
normal use. To help control end-to-end spacing, darker-colored 
decking should be kept at ambient temperature and shaded from 
direct sun prior to cutting and immediate securing. To create less 
visible gapping, use lighter-colored boards in the eld of the deck 
with darker-colored boards as design accents.

Note: In areas where extreme temperature swings are prevalent, 
adding 2X blocking at butt joints is recommended.
When installing blocking for more intricate decking patterns, 
remember that solid blocking (blocking laid on the at) will inhibit 
water ow and result in buildup of organic materials over time, which 
will make cleaning more difcult. When blocking is required, install 
ladder style for best results.
