The hybrid construction method unique to Imperial Brown was ideal for a 20’x32’ walk-in combo unit with large slider door, built for a Las Vegas restaurant. The construction combines low-density urethane, or soft-nosed wall panels (LDU), with hard-nosed wood-frame ceiling panels (WFU). With our hybrid method, designers can apply the construction method that best fits the application for the most well-built, cost-effective unit. In this application for a White Castle restaurant, the 20’ span was built economically, since the wood-frame ceiling panels require no roof support. The hybrid method lowered the cost and was easier to install.
