Multiple Choice

On liferafts, which component has two layers to insulate the inside from extreme temperatures?

The canopy is designed to create a sheltered, thermally stable space for survivors. It uses two fabric layers with an insulating layer between them, which forms a thermal barrier that helps keep the interior warmer in cold conditions and cooler in hot sun. The outer layer protects against wind, spray, and UV, while the inner layer traps air to reduce heat transfer. This insulation is specifically about the living space inside the raft, whereas other parts like the floor, hull, and valves serve different functions such as keeping occupants dry, providing buoyancy, and controlling inflation.
