Moisture concerns and the importance of a vapour barrier

Moisture worries are key when it comes to external wall insulation. A vapour barrier is necessary to stop moisture build-up. It acts as a shield. Any water vapor present is kept away from the insulation material.

A vapor barrier reduces condensation. It stops warm, moist air from reaching cold surfaces inside the walls. This means less dampness, mold, and structural damage.

The material for the vapor barrier should be non-permeable. Polyethylene sheeting or foil-faced insulation boards are good options. They have low water permeability, blocking out moisture.

Proper installation of the vapour barrier is important. It should be tight and secure, with no gaps. These steps ensure no moisture penetrates.

In conclusion, a vapour barrier is necessary for external wall insulation. It minimizes moisture and condensation. The right materials and installation techniques will protect the property against damp and maintain structural integrity.
