DECLARED TOTAL SYSTEM R-VALUES
Trade SelectTM Brane® VHP is a Very High Permeance, High Water Barrier building membrane
The contribution of this product to the total R-value depends on installation
and environmental conditions. The R-value will be reduced in the event of
the accumulation of dust on upward facing surfaces and in those cavities
that are ventilated
made with a three-layer construction: two outer layers of spun-bonded fabric protecting an inner
core of Very High Permeance membrane.

This design overcomes the shortcomings of typical single-layer products, which often either
have much lower permeance (and are therefore unsuitable for applications where a Very High
Permeance is required); or otherwise are not reliably waterproof, or do not even claim to
be waterproof.
The advanced product design of Trade SelectTM Brane® VHP ensures a Very High Water Vapour
Transmission (WVT) rate of 1584 grams per square metre per 24 hours under standard test
conditions and a guaranteed High Water Barrier tested in accordance with
AS/NZS 4200.1:1994 Pliable building membranes and underlays, Part 1: Materials; both
of these properties captured in one product ensures Trade SelectTM Brane® VHP is the most

Trade SelectTM Brane® VHP is an important element in the design of buildings to avoid future
condensation risks and associated structural problems of decay and corrosion, as well as
“sick building syndrome” caused by mould.

Application
 Trade SelectTM Brane® VHP is used as a wall wrap behind bre cement and timber cladding
in most Australian climates. (Note: it is NOT recommended for this application in the humid
tropics, use Medium Vapour Barrier Trade Select Wall Wrap instead.)

Installation
Trade SelectTM Brane® VHP should be installed in accordance with AS/NZS 4200.2:1994 Pliable Building Membranes and Underlays,
Part 2: Installation Requirements. Trade SelectTM Brane® VHP is to be installed horizontally as a continuous membrane by pulling taut
and Àxing to all framing members with the printed side facing out. Trade SelectTM Brane® VHP should extend from the top plate to the
bottom plate on concrete slabs or bearers in timber construction. During installation use Àx galvanised clouts or staples in timber
construction, and tech screws in steel construction. In high wind areas it is recommended to use Áat, punched multi-point fasteners,
or cap screws. Trade SelectTM Brane® VHP should be overlapped no less than 150 mm at all joins to facilitate drainage. To shed water
outwards, stagger and overlap all joins. If using a stapling tool, take care not to puncture live electrical cables.
Any damage made to Trade SelectTM Brane® VHP during installation, including holes and tears, must be repaired.
Trade SelectTM Brane® VHP is not designed to withstand prolonged direct exposure to UV light and the elements. Outer cladding should
be installed without delay.
Health and Safety Information
Ametalin has assessed this product according to the criteria outlined in the National Occupational Health and Safety Commission
(NOHSC): 1008 (1998) and NOHSC: 1005 (1999). As a result of the assessment, this product is classiÀed as non-hazardous according
to the NOHSC criteria.
NCC/BCA Compliant
Trade SelectTM Brane® VHP complies with AS/NZS 4200.1:1994 and therefore satisÀes all general requirements of the National
Construction Code and Building Code of Australia.
Dimensions
Trade SelectTM Brane® VHP is sold in sizes:
2740 mm x 30 m (82.2 m²)
The speciÀcation of permeance of building membranes depends on a number of factors including construction type, materials, climatic data, site-speciÀc conditions, and very importantly settings and maintenance of air
conditioners as well as care taken to avoid damage to the membranes. The Trade Select web site www.tradeselect.co provides guidance to assist designers in understanding the issues surrounding water vapour management in
buildings, and offers solutions for a notional “typical” building at a number of locations around Australia. It should be understood that our guidance is just that; it is not deÀnitive advice upon which to base a design decision.
Users are advised NOT to rely on Trade Select’s general guidance, but to seek advice from a qualiÀed engineer based on actual design and site conditions. It is almost impossible to guarantee that a building will never have
condensation problems. The object of our guidance is to assist designers in making an appropriate trade-off between risk and cost. Correctly specifying building membranes – vapour barriers, vapour retarders and permeable
membranes as appropriate -, to manage vapour movement and reduce the risk of moisture problems, should be based on a hygrothermal analysis during critical months. This examines the temperature and dew point proÀles
through the building element. Trade Selects consulting engineers can undertake a project-speciÀc hygrothermal analysis based on parameters supplied by the client at a relatively modest cost.
