HardieWrap weather barrier

HardieBreak HardieBreak HardieBreak


HardieWrap™ weather barrier is a non-perforated, highly breathable and reflective^ safe-glare weather barrier designed to be used in both commercial and residential wall and gable applications behind James Hardie® cladding and Scyon™ external cladding and other external cladding products for which it meets the cladding manufacturer's recommendations.

Made from an advanced triple-layered material, HardieWrap™ weather barrier has been engineered for the Australian climate. It delivers a triple-shield of protection to help against external weather penetration, internal condensation build up and external heat penetration.


^HardieWrap™ weather barrier has an outward facing low e reflective surface with an emittance value of 0.16 tested in accordance with AS/NZS 4201.5. Please refer to the HardieWrap™ physical properties table for more information.

R-values

The contribution HardieWrap™ weather barrier to the total R-value depends on installation and environmental conditions. The following table provides total R-values for common systems in accordance with AS4859.1:2002 and Amendment 1:2006 Materials for Thermal Insulation of Buildings. Note that the R-value will be reduced in cavities that are ventilated.

Notes:
1. Metal frames do not consider thermal bridging as a thermal strip to be installed.
2. The above published Total R values for the above building system configurations were independently assessed in accordance with AS NZS 4859.1:2002 ‘Materials for the Thermal Insulation of Buildings’, by certified engineers and industry organisations.
3. Scyon™ Linea weatherboards will add up to 0.2 to the total system R-value when fixed direct to frame.

PREMIUM PROTECTION. Made from a non-perforated and non-woven material that contains highly breathable micro-pores, HardieWrap™ weather barrier helps block the external penetration of water, air and dust, without compromising breathability. This gives it a high level of resistance to external weather.

ENHANCES THERMAL PERFORMANCE. HardieWrap™ weather barrier has a reflective ‘safe glare’ top layer that is able to be installed outward facing, to help maximise the deflection of light and heat. This enables energy savings in reduced heating and cooling consumption. In addition to this, HardieWrap™ weather barrier controls the air flow behind the facade systems which in turn helps to boost thermal performance even further. For instance, when installing Scyon™ Linea™ weatherboards directly to timber or light gauge steel wall frames, HardieWrap™ weather barrier can improve your wall thermal performance by up to R0.3 m2K/W ^, without the need to increase your bulk insulation. **

REDUCES CONDENSATION BUILD UP. An average household can generate up to 12 litres of internal condensation on a daily basis. Condensation within the wall frame can result in accelerated frame deterioration, mould infestations, sick building syndrome and costly repairs. With the increasing air tightness and energy efficiency requirements, choosing the right weather barrier will help manage this condensation. HardieWrap™ weather barrier is made from a material that contains highly breathable pores that help interior water vapour to escape the building to the outside. This helps reduce the risk of condensation compromising the design life of the building and reduces the risk of negative financial and health consequences for the owners and occupants.

FAST AND EASY INSTALLATION. HardieWrap™ weather barrier is able to save you up to 50% in installation time and 10% in material wastage, compared to many other 1.35m wide products on the market. This is because it’s 2.75m wide and enables one storey: one pass. It is also lighter to carry than many other foil wall barriers, and rolls out without creasing, cuts easily with a utility knife, hangs on the wall flat and is quieter than most on a windy day.

SECURITY AND PEACE OF MIND. HardieWrap™ weather barrier complies with AS/NZS 4200.1, satisfies* James Hardie® external cladding warranty requirements and comes with a 10 year manufacturer’s warranty.

Made in USA

Foot notes:

*Specifier is responsible for confirming the suitability of HardieWrap™ weather barrier in the specific design and climate zone with the selected external cladding product. Refer to cladding manufacturer for more information.

^When compared to standard non-reflective and non-compressible weather barriers.

**When installed and maintained correctly and to the extent set out in James Hardie’s published literature current at the time of installation.

Where do you use it? Material - Click to view

X

HardieWrap™ weather barrier can be used in wall and gable applications in all Australian climates zoned from 2 through to 8. Similar to most wall wraps, the exception is zone 1 – the hot and humid tropics of Far North Queensland, the Northern Territory and parts of Northern Western Australia. *

It can be fixed to timber or light gauge steel frames, beneath James Hardie®, Scyon™ and other* external cladding, in residential, medium density and commercial buildings. It is also suitable for all zones in bushfire construction and can be used in conjunction with James Hardie’s fire rated wall systems.
