INTERLOC
Wall & Soffit Panel SystemThe Interloc Wall & Soffit Panel System is a smooth wall panel that can be installed both horizontally and vertically, and is commonly used as a soffit panel with perforations. This concealed fastener wall panel is installed on a floating clip system ideal for thermal expansion and contraction. The Interloc panel series comes in a variety of coverages with options for flush wall or 0.5” reveal.
Depending on the coverage chosen, the Interloc Panel comes in a flat pan, with v grooves, with perforations, or a combination of these options. Available in our Standard 24 gauge colour series, this panel can also be produced in our Woodgrain Series, FormaTouch Textured Series, and PVDF Kynar Colours.

Design Considerations:
Light gauge steel cladding with wide flat pans may exhibit oil canning which can affect the aesthetics of the building design.
Oil canning will vary depending on the time of day and angle of viewing and is usually more noticeable in darker colours.
Oil canning will also be more prevalent in wider pans and longer sheet runs. Building designers and homeowners should be aware of this and take this into consideration.
