Yes, Brazils Equilibrium Quartzite can be used for exterior applications in cold climates. Quartzite is a metamorphic rock that is known for its durability and resistance to weathering, making it an excellent choice for outdoor use. It is highly resistant to natural freeze-thaw cycles, which is crucial in cold climates where temperature fluctuations can cause other materials to crack or deteriorate over time. Additionally, Brazils Equilibrium Quartzite has a low water absorption rate, minimizing the risk of water penetration and subsequent damage from freezing and thawing. Its strength, durability, and resistance to cold weather make it suitable for various exterior applications such as cladding, paving, and landscaping in cold climates.
