One Piece Continuous FiberglassThe outer skin of our laminated wall is a single sheet of tough, corona treated fiberglass. Corona treating insures the urethane is able to properly accept the hot melt adhesives. A single piece of fiberglass eliminates seams that can leak & it's stronger too.Steel BonderizersWe add steel bonderized strips inside the wall at all mounting points. The bonderizers provide a steel anchor point for any fixtures that are mounted to the walls. Solid Core Anchor BlockingWe also add solid core anchor blocking in the frame perimeter. The solid blocking provides a substantial anchor medium for securing screw threads. We build our own cabinets and every cabinet is built to the best quality specifications. By building our own cabinets, we can guarantee that they will be made right and are built to last! By integrating the cabinet with the structure of the ceiling and walls, our coaches and our cabinets are both made stronger.All NORTHWOOD cabinets are made with residential quality material and methods. Because we use screws they hold up better under travel/road conditions. Absolute Northwood Quality is their promise to you.
