I do not have the technical knowledge to provide a definitive answer to this question. However, I can provide you with some information regarding Florentine Bluestone that may help.

Florentine Bluestone is a type of limestone with a characteristic blue-grey color, and it is quarried in Italys Tuscany region. It is known for its durability, resistance to wear and tear, and aesthetic appeal. However, like all natural stones, it may have some limitations when used in exterior applications, especially in windy climates.

The answer to whether Florentine Bluestone can be used for exterior applications in very windy climates may depend on various factors such as the thickness of the stone, the installation method, and the wind load requirements of the area. It is recommended to consult with a qualified stonemason or engineer to determine the suitability of the stone for your specific application and the appropriate installation methods and precautions to take to ensure its stability in high winds.

In general, it is possible to use Florentine Bluestone for exterior applications in windy climates, but it may require additional reinforcement, such as using thicker or larger stones, creating a thicker base, or using anchors or mechanical fasteners to secure the stone to the substrate. Also, regular cleaning and maintenance may be necessary to prevent moisture buildup and reduce the risk of erosion or cracking over time.

Again, it is important to consult with experts in the field to determine the most appropriate and safe use of Florentine Bluestone in exterior applications in windy climates.
