Introduction

Proctor Passive Wraptite-SA combines the best properties of a

vapour permeable membrane and a self adhesive water and air

barrier in one innovative self-adhering product.

Product Description

Proctor Passive Wraptite SA fully bonds without mechanical

attachments to most substrates for ease of installation, requiring

minimal use of sealants or tapes.

Proctor Passive Wraptite-SA utilizes a patented full coverage air

permeable adhesive to provide unsurpassed vapour

permeability in a commercial quality, self-adhered, water

resistant breather membrane.

Wraptite SA’s high vapour permeability allows damp sheathing

to dry quickly and moisture to escape. This ensures good indoor

air quality and reduces the likelihood of mould, mildew,

condensation, timber distortion and metal corrosion.

Key Features & Advantages

No primer required on most clean substrates.

Tough laminate resists punctures and tears.

Lightweight and easy to install.

Multiple substrate compatibility.

UV stable for up to six weeks of UV exposure in Australia

and New Zealand.

Wide service temperature range, easily installed in all

climates.

Tear, rip and puncture resistant during and after

construction, reducing install costs.

Zero VOCs, and free of any chemicals on the Living

Building Challenge Red List.

AS/NZS 4200.1 testing and compliance

Tested in accordance with ICC-ES-AC 38 criteria to meet

IBC and IRC requirements for Weather Resistive Barriers.

Proctor Passive Wraptite-SA is a multilayer laminate product and is not therefore suitable for testing to AS1530.1. Please note that Proctor Passive

Wraptite-SA is a polyolefin material and therefore does not meet the deemed to satisfy requirements in the National Construction Code (NCC) as a

non-combustible material. Wraptite SA has been assessed by BRE Global with regards to the impact on the fire performance of external wall systems

when expose to an external fire. Please consult your fire engineer if you wish you use Proctor Passive Wraptite-SA as part of a performance solution, for

example in type A , type B wall constructions and fire-protected timber.
