Can New Zealand's Poolburn Schist be used exterior applications in hot climates?
The Poolburn Schist from New Zealand is a type of metamorphic rock commonly used as a building material. While it is generally suitable for exterior applications, its performance in hot climates will depend on several factors.
Poolburn Schist has good thermal properties, which means it can withstand heat and does not retain it as much as other materials like concrete or brick. This can be beneficial in hot climates as it helps to keep the exterior surfaces cooler. However, it is important to consider a few things:
1. Color: The color of the Poolburn Schist can affect its heat absorption properties. Darker colors tend to absorb more heat, while lighter colors reflect it. If the Schist is a darker shade, it may become hotter to the touch in direct sunlight. Lighter colors are recommended for areas with intense sunlight.
2. Moisture absorption: Schist is a natural stone, and its porosity can vary. If the Poolburn Schist has a high porosity, it may absorb moisture, which can cause problems in hot and humid climates. Moisture absorption can lead to discoloration, staining, and weakening of the stone over time. To mitigate this, a proper sealer or protective coating should be applied to the Schist.
3. Weathering: Extreme temperatures and UV radiation from the sun can cause weathering of the stone over time. This can result in color fading, surface deterioration, and the development of cracks. Regular maintenance, including cleaning and sealing, can help protect the Schist from these issues.
In summary, while Poolburn Schist can be used in hot climates, a careful selection of color, proper sealing, and maintenance are crucial to ensure its long-term performance and durability. Consulting with a local stone supplier or an architect familiar with the local climate can provide more specific advice for your particular situation.
