A ground vapour barrier protects against rising damp and mould, making homes drier, warmer and easier to heat.
This ground vapour barrier is 250-micron thick polythene for maximum, lasting protection from cold and damp. The kit consists of one roll of polythene (4 x 25 m = 100 m2), 5 rolls tape and a box of pins.
Up to 35 litres of water a day can be released into a home from exposed soil under the house. This 'rising damp' moisture raises the inside relative humidity which can cause mould to grow and moisture problems such as condensation on walls and windows. A house with a high moisture content is often colder and more expensive to heat. Ground vapour barriers provide protection from the cold and damp ground, preventing moisture rising.
