The Steger Porphyry is a type of natural stone quarried in Italy, and it can be used for both interior and exterior applications. However, using it in very windy climates may require some additional considerations.

Porphyry is a highly durable and weather-resistant stone, making it suitable for outdoor use. It can withstand various weather conditions, including wind, rain, and freezing temperatures. However, in extremely windy climates, there are a few factors to consider:

1. Installation: Proper installation is crucial when using any stone in windy climates. The stone should be securely fixed using the appropriate installation methods and materials to ensure its stability.

2. Size and thickness: The size and thickness of the Steger Porphyry pavers or tiles can influence their ability to withstand strong winds. Thicker stones may be more resistant to potential damage from wind loads.

3. Jointing system: The jointing system used between the stones also plays a significant role in their stability. A well-designed and properly executed jointing system can provide additional strength and prevent dislodgement or movement of the stones in high winds.

4. Orientation and layout: The orientation and layout of the stones can impact their wind resistance. For example, a diagonal or herringbone pattern may provide more stability compared to a simple linear pattern.

Additionally, its essential to consider local building codes and regulations, as they may provide specific requirements for using natural stone in windy areas. Consulting with a professional architect, designer, or contractor experienced in designing for windy climates would be wise to ensure the proper application of Steger Porphyry or any other stone.
