The steward told officers that the man was trying to replace a plastic foam panel he had cut from the wall under the sink, apparently with a saw.
Laser-cut foam panels, designed to isolate noise and do away with echoes, cover the walls.
Rigid foam panels are made with or without barrier facings.
Structural foam panels are usually foil-faced on both sides.
Although construction is easy, plastic foam panels contain too much open space to fit many efficiently in a shipping container.
This purpose requires strategic placement of acoustic foam panels on walls, ceiling and floors, effectively eliminating all resonance within the room.
The effectiveness of acoustic foam panels can be increased by ensuring there is an air gap between the foam panels and the walls.
Doing this exposes a great surface area of the foam panels to incident waves increasing the amount of absorption.
Concrete was poured into the space between two foam panels.
The wall's two-inch-thick foam panels connect to a series of pulleys and cables that react when embedded sensors detect motion nearby.
