Walpanel Inc.

After decades of exterior cladding, off-site panel prefabrication, research and renovation, Walpanel Inc. has become a leading manufacturer and supplier of prefabricated exterior wall panels. In 2016, it relocated its headquarter to the United States, Maryland, and started to manufacture and sell its products under the brand of Wallshell. Since then, it has developed four cladding systems including two rain-screen systems, one face-sealed insulated cladding system and one prefabricated EIFS system. By 2016, Its total production has exceeded 100 million square feet.
