Tiles are an essential part of home decoration, especially in kitchens and bathrooms. While wood flooring may contain harmful substances like formaldehyde, tiles can also emit radioactive materials—so it's not always "completely safe." In today's eco-conscious era, choosing green, environmentally friendly ceramic tiles has become a top priority for many homeowners. Here, Jiuzheng Building Materials Network shares some useful tips on selecting eco-friendly tiles to help you make the best choice.
**Why Choose Green Tiles?**
Although tiles naturally contain some level of radiation, especially glazed ones, the levels are generally low and much lower than that of a mobile phone. However, some manufacturers add zirconium sand—which has higher radioactivity—to improve the tile’s surface finish. Prolonged exposure to such materials can pose health risks. Eco-friendly ceramic tiles, on the other hand, meet strict safety standards. Their radioactivity levels fall under Class A, which is safe for use in homes without restrictions.
**How to Choose Environmentally Friendly Tiles**
1. **Choose Reputable Brands**
When shopping for tiles, always go for well-known brands that have been tested and certified by national authorities. Look for environmental labels, quality management certifications, and inspection-free marks. Brands like Dongpeng, Marco Polo, and Faenza have consistently met national standards in recent years, making them reliable choices.
2. **Check the Radioactivity Level**
According to the updated “Code for Indoor Environmental Pollution Control of Civil Building Engineering,†the radioactivity of porcelain tiles used indoors must be tested. The results are divided into three categories: A, B, and C. Only Class A tiles are suitable for home use. Some unscrupulous companies might use B or C tiles but pass them off as A to cut costs. To avoid this, consider having a professional agency test the tiles before installation.
3. **Inspect the Quality Carefully**
- **Look:** The color should be even, with a smooth and flat surface. Check for cracks, bubbles, spots, or pitting. Compare several tiles from the same box to spot any color variations or defects.
- **Listen:** Tap the tile with a hard object. A crisp, clear sound indicates better quality. If it sounds dull, it may be of lower quality.
- **Test:** Pour water on the back of the tile. The slower the water is absorbed, the denser and higher-quality the tile. Fast absorption means lower density and poorer quality.
By following these steps, you can ensure that your tile selection is both beautiful and safe for your home. Always prioritize your family's health when making such important decisions.
