Great example of why a ground vapour barrier is important. Do you know what's under your house? If not it's worth having a look.
This photo is from an underfloor area during a Healthy Home Assessment in Whanganui, this is a clear reminder of why a vapour barrier is important, especially under homes with enclosed foundations.
When moisture is trapped under a house, it can create the perfect conditions for mould, fungi, and dampness to spread. Over time, this can contribute to wood rot and allow moisture to move up into the home.
A ground vapour barrier helps reduce moisture rising from the soil, keeping the underfloor area drier and supporting a healthier, more energy efficient home.
If your home has an enclosed foundation, it’s worth checking what is happening underneath. A dry underfloor space can make a big difference to the comfort and health of your home.
