UFP EDGE thermally modified wood siding

This wood cladding is modified with an all-natural heat and steam process that stabilizes the wood, making it less vulnerable to shrinking and seasonal shifts. This thermal modification process alters the wood’s fiber cells. This process bakes the wood, making it rich in color, resistant to rot, dimensionally stable, and lighter in weight with improved thermal insulation properties.
