The necessity of a vapour barrier on internal walls largely depends on the specific conditions and requirements of your space. In environments with high humidity levels, such as kitchens, bathrooms, or swimming pools, implementing a vapour barrier can be crucial to prevent moisture build-up and condensation, which could lead to mould and water damage over time.

Vapour control plasterboards from Workplace Interior Shop are an excellent option for these scenarios, as they come with an integrated vapour barrier in the form of a silver metallised polyester film back liner. This feature effectively manages moisture, ensuring a dry and insulated interior.

For standard internal walls in less humid conditions, a vapour barrier may not be strictly necessary, but it’s always best to assess the specific needs of your space or consult with a professional to make an informed decision.
