True Black Hebra Slate

True Black Hebra is quarried in La Baña, situated in the León region of Spain. It is smoother and finer in texture than True Black Galcar, and its strong vertical grain reflects light differently, resulting in a quite dissimilar appearance on a roof. Overall, it has a very refined look. True Black Hebra is slightly darker than True Black Galcar but its other qualities are fairly similar. Rated S1 Grade pursuant to ASTM standards. Its test results are excellent and it is easy to work with (no need for power tools). Alpine conditions pose no problems for it.
