Rejuvenation: a term from the sports application of artificial grass – used when maintaining artificial grass pitches used as playing fields. A purpose built machine is used to lift and clean the rubber crumb.
Roadside verges: a growing use for artificial grass. Local authorities are also increasingly using artificial grass on roundabouts and car park verges.
Roof gardens: an ideal use for artificial grass, easy to lay, low maintenance and usable all year round.
Sand dressed pitch: used in sports applications, the sand infill usually comes to within 10 mm of the tip of the fibres. The infill cannot readily be seen.
Sandfilled pitch: again a sports term, the sand infill reaches to the top of the fibres producing a hard and rough surface.
Seams: when installing artificial grass you will usually need to join different rolls together. Using seaming tape and glue gives a secure seam or join.
Shock Pad: for some installations a shock absorbent underlay is used. Children’s play areas and schools will typically use a shock pad underneath the artificial grass. The thickness of the shock pad will determine the CFH (Critical Fall Height) and be a key influence for any risk assessment.
Softness: the thickness of the fibres is usually a good indication of how soft the artificial grass will be. Ideally the fibres will form a soft pile which will remain upright.
Stitches per 10cm: another manufacturing term; the number of stitches per 10cm dictates the grass carpet pile weight.
Swimming pools: artificial grass is often used as a surround for swimming pools. Ideally there is a separation of up to 3 feet between the pool and the grass to minimise damage by chlorine.
Synthetic grass: another term for artificial grass.
Synthetic turf: another term for artificial grass.
Tear resistance: a term used to denote the strength of the fabric especially when used in a sports environment.
Top up: with any sand infill artificial grass product, the infill itself (sand or rubber crumb) will periodically need to be topped up. Largely depends upon the amount of use.
Total cost of ownership: the sum of all the costs from installation through to disposal. A high quality artificial grass with a long life will usually have a lower total cost.
Unfilled pitch: this is where the pile within artificial grass is unfilled. Used in sports applications, these “fast” surfaces are favoured for hockey pitches. They need regular wetting and are sometimes referred to as “water-based” pitches.
U.V. stabilised: this means that ultra violet light should not degrade the colour of the artificial grass. As a manufacturer of artificial grass, we test our products to ISO standards for UV resistance.
Water shortages: a key driver for introducing artificial grass.  For instance, in Arizona water is so short that residents are given financial incentives to install artificial grass and substantially reduce their water usage.
Yarn: specialist yarn made of polyethylene and polypropylene is used for artificial grass manufacture – we use only top quality from the world’s leading, specialist supplier.
Yarn height: a manufacturing term; yarn height is equivalent to the pile height plus the stitch through the backing.
Yarn sheet: another manufacturing term, this is what you see when looking at the many strands are yarn passing down through bars to the needles for the tufting process.
