Turkeys Sky Onyx is a type of onyx that is widely used for interior applications such as countertops, wall cladding, and flooring. Due to its delicate and translucent nature, it is generally not recommended for exterior applications, especially in cold climates.

Cold climates pose several challenges for onyx, including freezing temperatures and exposure to harsh weather conditions. These factors can cause the stone to expand and contract, leading to cracking, chipping, and deterioration over time. Additionally, onyx is vulnerable to staining and color change when exposed to moisture, which can be further exacerbated in cold and wet environments.

Therefore, it is advisable to choose a more suitable and durable material for exterior applications in cold climates, such as granite or porcelain tiles, which are known for their strength, resistance to freezing temperatures, and ability to withstand outdoor elements.
