Install rainscreen façade systems
Overview
This standard is about installing rainscreen façade systems to previously prepared and inspected backing walls. This will involve the setting out and fixing of the helping hand brackets, carrier system and any sub-grid required to line and level, adjusting and cutting to fit prior to securing into position including any vapour barriers/breather membranes, insulation and cavity barriers in accordance with the rainscreen façade system design and specification
This standard will also involve interpreting information, adopting safe, healthy and environmentally responsible work practices, selecting and using materials, components, tools and equipment, minimising damage and working within the allocated time, in accordance with organisational requirements which are equal to or exceed current statutory and legislative requirements
This standard is for people working in the occupational area of rainscreen façade systems and can be used by operatives, supervisors and managers
