Where it works well

Thermally Modified Ash is a separate material choice for projects seeking a darker appearance. Tell us whether the boards are for interior or exterior use, along with the profile, dimensions, finish, and quantity.

What heat treatment changes

Heat treatment gives Ash a darker appearance. It is part of the material, not a surface finish, and it does not replace the project specification. Confirm the intended use, profile, fastening, and finish with the quote. Conventional Ash is listed under Related.

Grades and appearance

Thermally Modified Ash product listings include Clear grades. The grade depends on the selected product and dimensions. Include the grade from your plans or the product you want to match. We will confirm the grade, dimensions, and availability with your quote.

Photos

Application illustrations can help you describe the look you want. Captions distinguish general examples from species-specific illustrations.
