Thermally Modified Porch Flooring That Lasts

For a porch floor that resists warping, rot, and insects, but embraces everything there is to love about real wood, Thermory Benchmark Ash porch flooring delivers. Thermory's expert thermal modification process takes white ash boards and uses just heat and steam to result in unequalled durability and dimensional stability. Then, each board undergoes meticulous milling, ensuring it exceeds your expectations for smoothness, flatness, and straightness. Thermory has sustainability built into their company values, and they're committed to using only responsible harvesting practices, earth-friendly processes, and features that minimize waste.
