Thermal Bluestone
Pennsylvania Bluestone is dense, strong, fine-grained sandstone quarried only in the northeastern tier of Pennsylvania, parts of northern New Jersey and the southern tier of New York. It is an excellent material for decks and patios as it resists cracking and won’t discolor. It easily can be separated into slabs of varying sizes, making it suitable for other architectural details such as steps, walls, entrance walkways, building facades, interior floors, and fireplaces.
