What are the differences in thermal shock resistance between resin composites and terracotta planters?

When choosing planters for outdoor use, thermal shock resistance is a critical factor. Resin composites and terracotta are two popular materials, but they perform differently under temperature fluctuations.

Resin composites are engineered for durability, offering high thermal shock resistance. They expand and contract minimally, reducing the risk of cracking in extreme weather. This makes them ideal for regions with rapid temperature changes.

Terracotta, while aesthetically pleasing, is more prone to thermal shock. Its porous nature absorbs moisture, which can freeze and expand in cold weather, leading to cracks. Repeated exposure to temperature swings accelerates wear.

For long-lasting garden pots, resin composites outperform terracotta in thermal shock resistance. However, terracotta remains a classic choice for mild climates. Consider your local weather conditions when selecting the best material for your planters.
