How are airplanes insulated?
Modern commercial airplanes cruise at a high altitude where it is extremely cold. To withstand the cold atmosphere, the airplane’s inner skin is covered by a layer of fiberglass insulation. Insulating materials reduce the flow of heat or electricity. Thermal insulation decreases the flow of heat from a hot region to a cooler one.Temperature-stabilizing insulation is a key component of effective environmental control systems in aircraft interiors and cabins. Insulation is used to shield air ducts, tubing, and air-cycle systems, as well as paneling for fuselage interior walls, ceilings, and overhead storage compartments. Thrust reversal systems.
What is aircraft insulation made of?
Aircraft thermal acoustical insulation consists of lightweight fiberglass encased in a thin film bagging material. Practically the entire fuselage is layered with insulation blankets to deaden noise and insulate against heat or cold. Acoustic and Thermal Insulation for Fuselage and Bulkheads POLYDAMP® Hydrophobic Melamine foams are used for thermal and acoustical insulation in aircraft fuselages and bulkheads both alone and with films or high-mass fabrics.
