PROCTOR PASSIVE SARKING (RS-IT) for RAINSCREEN APPLICATIONS

PROCTOR PASSIVE (RS-IT) for RAINSCREEN APPLICATIONS

Product Description

ProctorPassive™ Rainscreen with Integrated Tape (RS-IT) is a two layer membrane consisting of a spun bonded polyester layer with a unique functional coating that offers improved resistance against UV and high temperatures up to 120°C. Developed primarily as a vapour permeable sarking for use in open joint rain screen applications, ProctorPassive RS-IT offers a combination of durability and high water holdout without compromising vapour permeance.

Applications

ProctorPassive RS-IT is suitable for installation in vertical wall constructions behind ventilated facades with regularly spaced open joints no greater than 30mm wide accounting for no more than 30% of total surface area. The rainscreen façade has to be ventilated according to the façade manufacturers installation instructions but a ventilation gap (min. 20mm) is necessary.

ProctorPassive RS-IT can also be used as a vapour permeable underlay in metal roof applications.

Long term UV resistance is dependent on the percentage of the cladding that is open, the size of openings, and the width of the cavity. Please contact Proctor Group Australia to seek assurances on the suitability of ProctorPassive RS-IT for the particular application.

Installation

ProctorPassive RS-IT should be installed in accordance with AS/NZS 4200.2 Pliable Building Membranes and Underlays, Part 2 Installation Requirements and in full accordance with the product installation guide. ProctorPassive RS-IT should be installed with the darker black "rubbery" surface facing outwards.

Integrated Tape

To improve the integrity of installation, ProctorPassive RS-IT is supplied with a factory applied integrated tape on the outer face of the lower course and the rear of the upper course of membrane.

Durability

Although ProctorPassive RS-IT can be used as temporary protection during construction, it can not be used as a fully exposed waterproofing membrane. The product may be damaged by careless handling, high winds or vandalism, and should not be left uncovered for longer than is absolutely necessary. Any damaged areas should be replaced before completion. To ensure maximum long term UV durability, ensure that ProctorPassive RS-IT is covered up by the primary cladding material as soon as possible, and not left exposed to UV for longer than 4 months, or 11 months when the cladding is closed joint.
