Brazils Saratoga Soapstone is a relatively soft and dense natural stone that can be used for a variety of applications, including exterior use. However, when considering its use in very windy climates, there are a few factors to consider:

1. Durability: While soapstone is generally durable and resistant to weathering, it is important to note that it is softer and more prone to scratching compared to other natural stones like granite or quartzite. In a very windy climate, where debris and particles might be carried by the wind, the soapstone may be more susceptible to surface damage.

2. Moisture Resistance: Soapstone is relatively non-porous, meaning it has low water absorption. However, in areas with very windy and wet conditions, prolonged exposure to moisture, such as heavy rain or snow, might affect the longevity of the soapstone and lead to potential issues such as staining or freezing/thawing cycles.

3. Thermal Expansion: Soapstone has a low thermal expansion rate, which is generally beneficial in exterior applications. However, in very windy climates with extreme temperature variations, the repeated expansion and contraction cycles might lead to the potential cracking or splitting of the soapstone.

Therefore, while Brazils Saratoga Soapstone can be used for exterior applications in windy climates, it is important to take proper care and maintenance. Regular sealing and protection from potential impact or debris can help prolong its lifespan and maintain its appearance. Additionally, consulting with a local stone supplier or a professional in your area who has experience with soapstone in similar climates is advisable to ensure suitability for your specific conditions.
