Thermory Flow decking combines the dimensional stability, durability, rich dark tone and gorgeous grain of thermo-ash with the stunning curved design from Flow. The complex design and production process create the curves by machining the boards, piece by piece, into six different shapes. Each Thermory Bole six-piece curved decking module slots perfectly into the next, creating an endless repeating pattern with a natural look.

Width 90-180 mm, length 2400 mm. Six boards per pack, covering an area of 1.83 m².
