How does the thickness of marble slabs impact the insulation of outdoor tree boxes?
The thickness of marble slabs plays a crucial role in the insulation performance of outdoor tree boxes. Thicker marble slabs provide better thermal resistance, reducing heat transfer and protecting tree roots from extreme temperature fluctuations. This is due to marble's natural density and low thermal conductivity, which help maintain stable soil temperatures. Additionally, thicker slabs offer enhanced durability against weathering and mechanical stress. For optimal insulation, a slab thickness of 2-3 inches is often recommended, balancing effectiveness with practicality in urban landscaping designs.
