This paper describes applications of Paraweb Fence. The fence has been installed as snow and windbreak fencing along the A470 in the Brecon Beacons in Wales and also around the entrances to the Channel Tunnel. Paraweb is manufactured by John Ward (Holdings) from a composite polymer material. The fence is designed to provide a solid area of 54% giving a porosity of 46%. The principles by which windbreaks provide protection are outlined. The minimum recommended height for a windbreak is approximately twice the height of the item being protected and the optimum porosity is 40-50%. As windbreaks destroy or reduce wind velocities, they can also be used to control the drifting of snow or sand and to protect buildings and aid energy conservation. Paraweb Fence is non-conductive, discourages ice build-up, is light in weight and impervious to the corrosion effects of soils, salts and water.
