What is Bulkheads?
Bulkheads are walls or partitions used to separate spaces, hide building services, or keep soil and water from moving into an area.
Definition
Purpose
The primary purpose of a bulkhead is to enclose, separate, or retain something. Interior bulkheads let contractors conceal services without placing them in the main ceiling space. They can also be used to adjust ceiling height or to finish around cabinets. Bulkheads outside can hold soil in place and protect an edge facing the water. On boats and ships, they partition the interior.
Examples of Use
- Ceiling Bulkheads: A framed box below the ceiling can cover air ducts, plumbing lines, electrical wiring, or other items running through the space.
- Kitchen Bulkheads: These are commonly built above cabinets when the gap between the cabinets and ceiling needs to be closed off.
- Shoreline Bulkheads: A wall along a waterfront holds back soil and helps reduce damage from waves, currents, and erosion.
- Trench Bulkheads: A barrier across a trench can be used where water flow or loose fill could cause problems during or after utility work.
- Marine Compartments: On ships, bulkheads separate rooms or compartments and may be built to limit the movement of water or fire between sections.
