Underfloor and Ground Vapour Barrier (GVB)

About Underfloor and Ground Vapour Barrier (GVB)

About 30% of New Zealand homes are damp, and many houses have mould. Dehumidifiers and ventilation systems help fix the symptoms of the problem but don’t always tackle the cause itself. In many cases, dampness is relatively cheap and easy to fix.

Installing Ground Vapour Barrier is one of the best things you can do to put a cap on rising damp which lowers the moisture level in your home. This will reduce condensation and mould, as well as make the air feel more comfortable and the home easier to heat.
