R2 8 required bca value for block veneer construction.
Permeable wall and roof sarking.

Bradford enviroseal vapour permeable roof sarking can minimise the risk of condensation that can lead to damaging mould growth.
Most often called sarking sarking type material or wall wrap these building wrap membrane products are installed within the building envelope of a given dwelling type to do one or more jobs.
Doing these jobs well depends largely on the location of the building and obviously how well the membrane has been chosen transported handled placed.
R0 56 vapour permeable sarking facing cavity.
Bradford enviroseal vapour permeable wraps can minimise the risk of condensation inside the wall that can lead to damaging mould growth.
Enviroseal proctorwrap vapour permeable products enviroseal proctorwrap rw is a light duty triple layer spun bond vapour permeable wall wrap for use with brick timber steel fibre cement james hardietm sheeting products and hebel construction in residential and light commercial wall construction.
It allows water vapour to safely pass through and condense on the outside of the wall.
Recommended for use in colder climates.
R4 6 required based on solar absorptance value of 0 45.
For cooler climate zones a vapour permeable sarking can greatly improve weather resistance and lower the risk of condensation by allowing internally generated water vapour to escape the building.
R0 56 reflective sarking facing cavity.
R2 4 r3 49 achieved roof ceiling.
It allows internally generated water vapour to safely pass through condense on the outside and drain into the gutter.

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.
Bca value for pitched roof flat ceiling.
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.
