What are the thermal shock resistance properties of engineered quartz tops?

Engineered quartz tops are renowned for their durability and aesthetic appeal, but how do they perform under thermal shock? Unlike natural stone, engineered quartz is composed of approximately 90-95% crushed quartz crystals bound by resin polymers, giving it superior resistance to sudden temperature changes.

Thermal shock occurs when a material rapidly expands or contracts due to extreme heat or cold, leading to cracks or fractures. Engineered quartz, however, exhibits excellent thermal stability thanks to its resin binder, which absorbs stress and prevents structural damage. While it can withstand moderate heat (up to 150°C/300°F), direct exposure to very high temperatures—such as placing a scorching pan directly on the surface—can still cause discoloration or resin degradation over time.

For optimal performance, use trivets or hot pads to protect quartz countertops from extreme heat. Compared to materials like granite or marble, engineered quartz offers better resistance to thermal shock, making it a reliable choice for busy kitchens. Its non-porous nature also prevents moisture absorption, further enhancing its durability under varying temperatures.

In summary, engineered quartz tops provide strong thermal shock resistance, but proper care ensures long-term beauty and functionality.
