You may be surprised to learn that yurts have fewer mold issues than most conventional buildings. Yet it is a frequent question with legitimate fear of health issues that can derive from mold. Yurts of Hawaii addresses mold on their FAQ page because after all, they most frequently build in the rain forest.
No doubt about it, the best mold prevention anywhere on anything is air flow and sunshine. Other yurt sites address mold issues differently, typically focused on the material, ─ but the essential requirement is ventilation. To conclude that the vinyl material is a better mold prevention than the canvas with acrylic coating, or otherwise, is speculative.
All successful yurt makers do their research to select mold-resistant fabrics. Below are some construction and exterior tips verified in Hawaii, but beneficial anywhere:
- Elevate the yurt, preferably a minimum of three feet.
- Clear trees and large plants, preventing shady moist areas, three to five feet around the exterior of the yurt, or the lanai/decking. (That means no hovering tree limbs).
- Maintain landscaping to prevent constant shade, allowing at least partial sun on all areas of the roof.
- Install the gutter system properly, ensuring no continuous drips.
