Engineered quartz, as it’s known, is made of quartz and flexible resins, a combination that has the strength of granite counters—with better impact resistance and more forgiving installation options. Colour can be added to the mix along with elements such as glass or mirrored chips to give a speckled appearance. Engineered quartz comes in a wide variety of shades and glossy or matt finishes, and are great for a low-maintenance, stone- effect look that's scratch-and stain-resistant.
Engineered quartz is hard, dense, nonporous, nonabrasive, and nonreactive to acids—attributes that make it perfect for use as countertops, backsplashes, walls, and even floors. Keep in mind that, like natural stone, it’s heavy. And it’s not recommended for use outside because the resins aren’t UV stable (warranties are voided for outdoor applications). In terms of heat resistance, the material is reportedly not affected by temperatures lower than 300 degrees Fahrenheit. That said, it shouldn’t be used as flooring over radiant heat because of possible damage from long-term exposure to heat.
