Pennsylvania Bluestone
Flamed flat and even. Made for pool decks, terraces and modern patios.
Thermal bluestone is Pennsylvania Bluestone whose surface has been treated with intense heat, which pops the top layer into a consistent, fine-grained texture. It is flatter underfoot and more even in tone than natural cleft, and it still holds excellent slip resistance.
That consistency makes thermal the favorite around pools, in wet areas and in modern designs: a flat, predictable surface for wet bare feet, with none of the high spots a split face can have. We stock thermal pavers in Blue Select and Full Color and ship them crated to job sites nationwide.

Common applications
Why thermal
Wet grip
The flamed texture holds traction when the deck is wet, the reason thermal is the default finish around water.
Clean geometry
Every piece is a flat, consistent plane, so diagonals, grids and large formats read crisply.
Dense stone
Low-absorption Pennsylvania sandstone that handles freeze-thaw winters and summer heat alike.
