Thermory® Benchmark Ash Decking No Groove
Thermory® Benchmark Ash decking is exceptionally durable and dimensionally stable with deep, rich color. Thermory® Benchmark Ash Decking is your timeless, stunning, long-lasting, barefoot-friendly, installs-in-a-breeze, real wood dream deck. The Thermory® process modifies each board completely through heat and steam, all the way to the core, leading to unequalled durability and stability without sacrificing the natural qualities of real wood.
This Thermory® Benchmark Ash Decking is not grooved, but is Joint End Matched (JEM), which is a machined structural end match that connects boards so you don't need to finish decking on a joist.
• 7% moisture content
• Smooth milling
• Minimal splintering, twisting, warping, cracking
• 25+ Year Rot Resistance
