How to Install Hebel Wall Panels on Timber Wall Frames

In this blog post, we'll be focusing on the installation of Hebel PowerPanel XL panels on timber wall frames.

Hebel PowerPanelXL is an external wall system for houses and low-rise multi-residential applications, including extensions and re-cladding of existing homes. Consisting of 75mm thick steel-reinforced panels, Hebel PowerPanelXL is easy to install on two-storey dwellings.

Panels are fixed vertically to steel horizontal top hats attached to the load-bearing timber or steel frame.  Installation of the panels is fast and can be done by two people. Professional Hebel installers can install up to 150m2 within 3 days depending on site conditions.
