Abstract
The invention relates to a shock pad comprising: a coherent plate having upper and lower major surfaces, wherein the coherent plate comprises at least one coherent layer comprising man-made vitreous fibres (MMVF) bonded with a cured binder composition; an upper membrane layer bonded to the upper major surface of the coherent plate; a lower membrane layer bonded to the lower major surface of the coherent plate; wherein the at least one coherent layer has a thickness in the range of 12 mm to 40 mm and a density in the range of 175 kg/m3 to 300 kg/m3. The invention also relates to a method of producing the shock pad, and use of the shock pad for absorbing shock in a sports field, for absorbing and/or draining water in a sports field, and for cooling the surface temperature of a sports field.
