Bluestone Blue, Thermal

* Shapes are squares and rectangles and the sizing is nominal to accommodate a joint.

Bluestone Blue Thermal flagstone (also referred to as Premium or Select Blue) is the gold standard for high-end, contemporary landscape architecture. Selected for its exceptionally uniform blue-gray color palette, this stone provides a sleek and sophisticated look that is ideal for modern patios, pool decks, and formal walkways. The thermal finish is achieved through a high-temperature process that creates a smooth, flat surface while maintaining a safe, slip-resistant texture.

Processed into precise patterned squares and rectangles, this flagstone allows for tight joints and a perfectly level installation. Available in 1″ and 1.5″ thicknesses, it is a versatile choice for both residential and commercial applications. Because of its consistent color and refined, non-reflective surface, Bluestone Blue Thermal flagstone serves as an elegant canvas that complements a wide range of architectural styles, from minimalist modern to classic transitional.

Available at Quarry Connections, Bluestone Blue Thermal flagstone is stocked for projects throughout the Mid-Atlantic including Maryland, Washington DC, Northern Virginia, and Delaware, with delivery options to keep your job moving.
