The Double Lock Standing Seam system is a roof and façade covering system. The traditional design offers architects freedom in their design as it can adapt and complement almost any roof shape. By forming a double fold on the up-stands, the Standing Seam profile allows long strips of profiled metal to be assembled creating distinctive shadow line effect. The Standing Seam sheets are laid on continuous ventilated decking and anchored using fixed or sliding concealed fixing clips. The low height of the seams (25mm) contributes to the agility and uniformity of the roof. When dealing with more complex designs this system portrays a more technologically advanced appearance. This system is particularly suitable for very large cladding surfaces and for structures located in regions of harsh climate, which are often subject to snowfall (mountainous continental climate), strong winds, and heavy rain.

Key Features

• Standard panel widths are a maximum of 530 mm.
• Perfect for both renovations, new residential & commercial buildings.
• Ease of installation with the use of seaming machines, significantly reduces installation time.
• Optimum water & wind resistance performance.
• Pitch options from 3º to a vertical installation.
• Installed on minimum 19 mm ventilated plywood with waterproof breathable vapor membranes.
• Material thickness 0.7 mm.

Installation

  • Standing Seam is installed with concealed clips on a minimum 19 mm plywood and a roof underlay.
  • For Roofing application the 25 mm seam is closed twice to avoid water ingress.
  • A 40 mm continuous air gap must be left clear beneath the plywood, on all roof pitches.
  • Continuous ventilation openings are made at the top and bottom.

Testing to Australian Standards

Standing Seam and Archclad Cliptray 25 mm profiles have been tested to Australian standards as 4040.3-1992 "Methods of testing sheet roof and wall cladding method 3: Resistance to wind pressures for cyclone regions".

Architectural Cladding Australia Standing Seam and Cliptray profiles have been tested to Australia Standards AS/NZS 1170.2:2002 Structural Design Actions - Part 2: Wind Actions. Clause 5.3.2. This report details the results of the debris impact testing carried out on a sample of Architectural Cladding Australia's profile only.
