The biggest advantage of non-infill artificial turf for roof environments is its reduced dead load.
Traditional artificial turf systems rely on infill materials such as silica sand and rubber granules to keep fibers upright and improve stability. While these materials improve certain performance characteristics, they significantly increase the total weight of the system.
Non-infill turf uses:
- Advanced fiber structures
- Curved and straight yarn combinations
- Reinforced backing systems
- Integrated shock absorption layers
to maintain stability without adding heavy infill materials.
Weight Comparison Between Different Turf Systems
| Turf System | Typical Surface Weight | Impact on Roof Load |
|---|---|---|
| Non-infill artificial turf | Approx. 2.5–5 kg/m² | Low additional permanent load |
| Traditional sand-filled artificial turf | Approx. 20–35 kg/m² including infill | Higher structural loading |
| Rubber-filled sports turf | Approx. 25–45 kg/m² including infill | Requires careful structural evaluation |
Actual weight varies depending on turf specifications, backing design, and installation method.
For rooftop applications, reducing unnecessary permanent load helps preserve more safety margin for other variable loads such as furniture, people, rainwater, and seasonal weather conditions.
