Utilihab interior panels use somewhat different attachment methods from that of exterior cladding because the user/assembler cannot directly access the back side of panels to install or engage mechanical fasteners. They must also accommodate more frequent change as building interiors are modified much more frequently than their exteriors. This collection of panels also covers walls, floors, and ceilings and must account for areas of high humidity and water exposure (bathrooms and kitchens).
In general, the interior finishing system employs pre-finished flush-mounted panels for walls and partitions, drop-panels for flooring, and suspended drop-panels or flush panels for ceilings. Less commonly, flush-mounted and fitted planking in various forms are used.
