We now supply Thermally Modified Vertical Grain Western Hemlock. This is a strong, stable wood that performs well outdoors without chemical treatments.

Heat-treating the hemlock makes it much more resistant to moisture, rot, and insects. It stays straighter and holds up better than regular hemlock in siding and other exterior uses.

Key Facts

• One side resawn, one side 24-grit sanded.

Why Choose It
