Pirmax HR Panels can be fully secured to a concrete soffit by using approved insulation fasteners. The recommended fixing rate is 11 insulation fasteners per panel where each fastener must have a minimum head diameter of 35mm and should penetrate the soffit by a no less than 40mm. In areas where the panel is not exposed to external wind pressure, 5 fasteners may be used in the layout shown below.
The fire rating, application and exposure will differ between applications and consideration should be given to ensure that the fixing anchor material complies with the requirements of each project.
