Glossary of Artificial Grass Terminology

Glossary of Artificial Grass Terminology

 

Confused by some of the jargon used by artificial grass suppliers and manufacturers?

When comparing the best artificial grass, you’ll need to look at more than just the realism of a product.

You’ll need to compare fibre weight, pile heights, fibre materials and even the primary and secondary backing layers.

But what does all this mean?

We’ve created this glossary to give you clear definitions of the terms used by the artificial grass industry.

 

 

Adhesive

 

Polyurethane or epoxy based products used to join two pieces of artificial grass, to secure artificial grass to various edging systems or existing surfaces such as concrete. Can also be used to secure artificial grass to foam underlay.

Can be supplied as two-part adhesive in either 10kg or 5kg quantities or one-part 330ml tubes applied with a gun applicator.

 

 

Aquabond (Adhesive)

 

A one-part urethane-based adhesive supplied in 330ml tubes and applied with a gun applicator. See adhesive.

Fibre Shape

 

The shape of the fibre formed after extrusion. Can be many different shapes, each with various strengths and weaknesses.

 

 

Foam Underlay

 

A soft, cushioning foam installed directly underneath artificial grass designed to provide both shock attenuation and drainage and protect against injuries from trips and falls. Available in 10mm and 20mm thickness, foam shockpads can also be used to mask undulations in existing surfaces when installing artificial grass directly on top of concrete, decking, asphalt or paving.

Some pads are made from recycled materials, while others are made from virgin materials and may be recyclable.

Complies with the Head Impact Criteria (HIC) required in some forms of application.

 

 

Galvanized Nails

 

Used to secure the perimeter of an artificial lawn to timber edging. Coated in zinc to prevent oxidisation or rusting.

 

 

Gauge

 

The distance between rows of stitching, visible on the backing. The smaller the distance, the denser the pile.

 

 

Head Impact Criteria (HIC)

 

An internationally recognised measure for the likelihood of head injury. Used in school or playground risk assessments prior to artificial grass installation to determine the thickness of foam shockpad required, if there is a risk of head injury as a result of falling from items of play equipment.

 

 

Instant Recovery® Technology

 

Instant Recovery® combines nylon and polyethylene synthetic fibres to produce a hard hearing, durable artificial grass that quickly recovers from foot traffic and garden furniture back to an upright position.

 

 

Join (or Seam)

 

The area on an artificial lawn where two separate pieces of artificial grass meet. Secured using joining tape and adhesive.

 

 

Joining Tape/Seaming Tape

 

A strong fabric with a rough surface texture used to apply artificial grass adhesive that will bond to the backing of artificial grass. Provides a permanently secured join resistant to the elements and usage.

 

 

Latex (Backing)

 

A secondary backing used to coat the primary backing, applied in various quantities and strengths. The secondary backing holds everything together and the higher the quantities of latex, the stronger the backing – a vital component of long lasting artificial turf.

 

 

Laying Course

 

A layer of aggregate, levelled and compacted, prior to laying artificial grass. May comprise of sharp or grit sand but for best results, granite or limestone dust should be used. Typically installed to a depth of 25mm.

 

 

Maintenance

 

Whilst the maintenance of artificial grass is minimal when compared with real grass, proper maintenance is paramount in ensuring a long lasting, high performing artificial turf.

Involves cleaning, removing debris, reinvigorating the fibres and topping up sand infill as necessary.

 

 

Natural Look® Technology

 

Natural Look® reduces the glare caused by reflection from synthetic fibres, ensuring a natural look from every angle.

 

 

NeoGrass Approved Installer

 

A fully trained and experienced artificial grass installer, regularly assessed by NeoGrass for quality and customer service.

 

 

Nylon

 

The strongest and most resilient synthetic fibre used in artificial grass manufacturing. More abrasive than Polyethylene and Polypropylene.

 

 

Perforations

 

Holes punches in the backing of artificial grass at regular intervals to allow the percolation of water. Allows up to 52 litres of water per square metre, per minute through the artificial turf.

 

 

Permeability

 

The rate at which the artificial grass allows liquids to percolate through the turf.

 

 

Pile Density

 

The amount and closeness of the artificial fibres, usually measured in stitches per square metre.

 

 

Pile Height

 

The lengths of the synthetic fibres from the primary backing to the tip of the fibre. Usually measured in millimetres.

 

 

Pile Weight

Polyethylene

 

The most common type of plastic used to form synthetic fibres used in artificial grass manufacturing.

 

 

Polypropylene

 

A plastic used to form synthetic fibres used in artificial grass manufacturing.

 

 

Polyurethane (Backing)

 

A secondary backing used to coat the primary backing that holds everything together.

 

 

Powerbrush

 

A mechanical tool used to reinvigorate and revitalise the fibres back to an upright position. Used by contractors to defibrillate the sand infill to the bottom of the pile. Can also be used to remove debris.

 

 

Primary Backing

 

A woven or non-woven fabric used in either single or mutiple layers, made from polyester of which the fibres are stitched to.

 

 

Rubber Crumb

 

A rubber infill used on sports pitches to mimic bounce and roll of real grass pitches.

 

 

Sand Infill

 

A fine, silica sand that is applied to artificial grass that lies at the bottom of the pile. A sand infill is applied for a variety of reasons and offers many advantages.

 

 

Seam

 

See ‘Join’.

Square Metre

 

A unit of measurement used to measure the area of a lawn.

 

 

Sub Base

 

A layer of aggregate that supports the artificial lawn and prevents it from sinking. Usually consists of either MOT Type 1 or granite or limestone chippings. Installed to varying depths from 50mm to 100mm.

 

 

Permeable Sub Base

 

A layer of aggregate that allows liquids to drain freely through the sub base whilst preventing the artificial lawn from sinking. Usually consists of either granite or limestone chippings. Installed to varying depths from 50mm to 100mm.

 

 

Thatch

 

A textured yarn that can be shorter or of a differing colour to the face yarn to create a realistic look.
