Installing a vapour barrier in a converted van!

Resistant and adaptable to all climates, this vapour barrier protection strip is added to your Biofib Trio insulation and allows it to breathe whilst preventing moisture accumulation.

Thanks to a hygrovariability factor greater than 100 in summer and winter, this vapour barrier allows moisture to pass through from the inside to the outside, thus enabling the Biofib Trio 45mm insulation to release the moisture it has absorbed. This will help prevent damage caused by moisture accumulation and its harmful consequences for your vehicle and your health (mould, condensation, etc.).

Furthermore, to ensure optimum efficiency, this vapour barrier must be fixed with Double-sided adhesive tape.

Please note: 1.5m wide roll, i.e. quantity in basket of 1=1.5m², 2=3m², etc.
