Builders Black film 1200 gauge
1200 Gauge – Black 1200 Gauge Builders Film - is an un-reinforced LDPE polythene membrane heavier grade than 1000 Gauge. Black polythene deteriorates at a much slower rate than clear polythene so can be left exposed to the elements for longer periods, so this film is a more lasting alternative. This roll is 3.5m by 15m multi-fold. Not recommended for use as a Radon Barrier. CE quality mark.
