When the indoor sports floor is specified, toxicity and fire resistance are non-negotiable. Because the indoor environment lacks the rapid air diffusion of the outdoor site, it is very important to purchase turf composed of polymers with low volatile organic compounds (VOCs) and heavy metal stabilizers. Comply with fire safety standards (such as ASTM E648 Class I or European Bfl-s1) to ensure that this product contributes to a safe and breathable indoor air quality.
The table below offers a comparative analysis of two typical specifications to guide your evaluation:
| Specification | Non-Infill Futsal System (Indoor) | Infill Football System (Outdoor) |
| Pile Height | 25mm – 35mm | 40mm – 50mm |
| Typical Dtex | 8,800 – 11,000 (High resilience) | 11,000 – 13,000 (Heavyweight) |
| Density (Stitches/m²) | > 40,000 (High density essential) | 16,000 – 21,000 |
| Gauge | 3/8 inch or narrower | 5/8 inch |
| Ball Roll Resistance | Very Low (Fast game) | Medium (Controlled game) |
| Maintenance | Low (Vacuum/Brush) | Medium (Re-distribute infill) |
For those who want to physically evaluate the structural integrity of the backing and optical fiber configuration, viewing the dedicated football field turf solutions page can provide more visual background on how these technical specifications are translated into a finished product.
