Artificial Turf Infill Types
Infills are divided into two categories:
1. Stabilising infills: Predominantly sand, at varying grades to weigh down the carpet and give structural integrity.
2. Performance infills: Usually rubber made from recycled sources, ground down into fine granules to prevent compaction, increase resilience and enhance playing characteristics.
Pile Structure - Artificial turf varies by its "sward" length - the tallest is the "grass" for rugby fields, and the lowest is the "grass" for lawns.
The weight refers to the quantity of yarn within a square metre of product, using the number of stitches and the gauge of manufacture. Historically, the pile weight of a product has dictated the quality and price, with the heavier products demanding a higher price in return for improved performance.
The height of the product gives an indication of its application and format. Most football products will have a pile height of between 40mm-65mm and shockpads are required for surfaces with a pile height below 60mm. Rugby surfaces always have pile height of 65mm and are installed with a shockpad. Hockey surfaces tend to be between 10-20mm, offering different performance characteristics than the longer pile products. Generally shockpads are used in hockey.
