Polythene

Polythene is widely used within the construction industry as a Damp Proof Membrane (DPM) and is manufactured out of a blown film of polyethelene polymer plastic. Polythene can be used as a Damp Proof Membrane within floors, roofs and cavity walls, however should not be used where a breathable membrane is required as polythene DPM’s are not breathable. Polythene is also available in a low grade quality for use as a dust sheeting, or Temporary Protective Sheeting as it is known.

 Polythene is available in 500 gauge, 1000 gauge and 1200 gauge. Another unit of grading for polythene is microns – 500 gauge is 125 microns (mu), 1000 gauge is 250 microns (mu) and 1200 gauge is 300 microns (mu). There is also a 2000 gauge polythene which is 500 microns (mu).

 The heavier the gauge of material the thicker and more durable the polythene sheeting will be. There are also 2 recognised standards for polythene, Building Board of Agrement (BBA) and the Packaging and Industrial Films Association (PIFA).

 500 Gauge and 1000 Gauge Polythene are available in Clear, Black and Blue colours, while 1200 Gauge Polythene is only available in Black or Blue. Temporary Protective Sheeting is generally supplied in clear only.

 500 Gauge, 100 Gauge, 1200 Gauge and 2000 Gauge Polythene come in rolls of either 4m x 25m or 4m x 50m, while Temporary Protective Sheeting  comes in 4m x 50m rolls only.

 Building polythene is also suitable for a number of uses around the home and garden such as plant protection.
