The thickness of polythene sheeting is expressed in gauge or microns and the higher the gauge/microns, the thicker the polythene. The gauge was the traditional imperial measurement of polythene thickness but has now been replaced by micron as the European metric standard. The gauge of polythene can easily be converted to a micron measurement by dividing it by four. Furthermore, if you want the thickness in millimetres then just divide the gauge by 4000. As an example, 1000 gauge = 250 micron = 0.25mm. A 250-micron sheet is considered a "HEAVY DUTY polythene and ideal for heavy-duty applications such as a damp proof membrane, for mixing cement, temporary roof covering, temporary window repairs, industrial protection, weather protection and for heavier duty wrapping for storage and transit.
