Requested uses

Thermally modified Ash is commonly requested for a darker, more stable board than conventional Ash. Confirm interior versus exterior use, milling, and fastening on the quote.

What thermally modified means here

Heat treatment darkens the board and changes how the wood moves in service. It is not a finish and not a substitute for a project specification. Ask us to confirm the product, profile, and use when quoting. Conventional Ash is listed under Related.
