Aircraft insulation systems and methods

An aircraft insulation system for providing fire penetration resistance and thermal protection, the aircraft insulation system comprising:

• two or more insulation blankets comprising two or more of bay blankets and cap blankets wherein each bay blanket has a greater thickness than a thickness of each cap blanket, each insulation blanket having an inboard side and an outboard side;
• a continuous fire penetration resistant cover material having a heat seal adhesive, wherein the fire penetration resistant cover material covers the outboard side of the two or more insulation blankets and is continuous between the two or more insulation blankets without any breakage;
• a continuous insulation cover film having a heat seal adhesive, wherein the insulation cover film covers the inboard side of the two or more insulation blankets and is continuous between the two or more insulation blankets;
• a thermal heat seal that joins the fire penetration resistant cover material and the insulation cover film together to form a continuous insulation blanket assembly;
• and,
• an ultrasonic heat seal or another thermal heat seal at a peripheral end of each of the two or more insulation blankets.

• covering the outboard side of the two or more insulation blankets with a continuous fire penetration resistant cover material having a heat seal adhesive, wherein the continuous fire penetration resistant cover material is continuous between the two or more insulation blankets without any breakage;
• covering the inboard side of the two or more insulation blankets with a continuous insulation cover film having a heat seal adhesive, wherein the continuous insulation cover film is continuous between the two or more insulation blankets;
• and,
• joining together with a thermal heat seal the continuous fire penetration resistant cover material and the continuous insulation cover film to form a continuous insulation blanket assembly.
