Building systems for thermal comfort, moisture management and energy efficiency

Why Brane® VHP?

Low flammability

Suitable for use in bushfire prone areas when tested to AS 1530.2-1993 in accordance with AS/NZS 4200.1:1994

Advanced triple-layer construction

Two tough outer layers of spun-bonded fabric protecting an inner core of VHP (Very High Permeance), High Water Barrier membrane

Next-generation wall wrap

Non-perforated, Very High Permeance membrane. Highest level of vapour permeability available on the Australian market

Wind, water and weather protection

High Water Barrier, Low Vapour Barrier (tested in accordance with AS/NZS 4200.1:1994)

Reduces condensation risk

Non-perforated, Very High Permeance membrane allows water vapour to escape while preventing liquid water from entering

Healthier home environment

Prevents mould growth and ‘sick building syndrome’ Fibre-free insulation systems for optimal moisture management

All-in-one protection against weather and condensation risk

Build to suit your climate zone

Australia is a diverse country with a wide range of climates. Different climate zones experience different weather challenges, and your home should be designed and built to suit the climatic conditions of your particular area or region.

Brane® VHP is suitable for use behind fibre cement or timber cladding in almost all Australian climate zones. (Apart from the Wet Tropics, where Medium Vapour Barrier/High Vapour Barrier products are required; SILVERSARK® xR or SILVERSARK® are recommended in these regions.)

*Note: Check cladding manufacturer’s requirements before installation.
