Sunlight Thermal Radiation – Is part of thermal radiation generated by the hot plasma of the sun.
Thermal Contraction – is defined as the tendency of matter to change in shape, area and volume in response to a change in temperature through heat transfer. It is the opposite of thermal expansion. When the temperature drops, atoms calm down and shrink. They aren’t bouncing so aggressively off of each other and don’t need that much space to coexist. When they shrink, the boundaries of the material shrink. The material contracts. Most solids, liquids and gasses contract when they are cooled.
Ballast – is defined as a heavy material used to improve stability and maintain balance and steadiness. In the turf world, the term Ballast is used to “Weigh down the turf, prevent wrinkling and give the entire turf system stability and longevity. Properly placing infill assists the turf fibers in maintaining vertical position.
Seam Separation – Separation of two sections of synthetic turf that are seamed together.
Seam Rupture– The breaking or bursting of two sections of synthetic turf due to thermal contraction, wear or manipulation by physical force.
Gauge: an outline of rows of tufted fibers stitched into the backing of synthetic turf rolls.
Adhesive Seam Compression: pressure that is applied to seaming area of two sections of synthetic turf onto adhesive glue and seaming tape
