Enviroseal proctorwrap is a range of advanced vapour permeable wall wraps and roof sarkings that help manage the risk of moisture and mould related issues in a home.
Enviroseal proctorwrap roof sarking is vapour permeable allowing water vapour to pass through it whilst preventing the entry of liquid water and dust from outside.
For hot humid climate zones a vapour barrier sarking can greatly improve weather resistance and lower the risk of condensation by preventing external water vapour from entering the building.
