Vapour Barriers

Vapour Barriers, as their name would suggest, serve as a 'barrier' against moisture, inhibiting the passage of water vapour between the outside and inside of a building structure. When insulating a property internally, a vapour barrier is an absolute necessity; the only exception to this is if your insulation already boasts a vapour-resistant layer. Vapour barriers are usually installed in conjunction with insulation to ensure a successful building enclosure.
