Abstract
An improved insulation system for vehicles and method of making and using the same are disclosed. The insulation system comprises one or more layers of insulative material sealed within a case which is impermeable to liquids while being at least in part moisture vapor permeable. When installed within a sealed vehicle where moisture vapor build-up is a problem, the insulation of the present invention serves to isolate condensed moisture from causing damage to the vehicle's contents or its shell. When moisture levels decrease within the vehicle, moisture is free to evaporate from the insulation and dissipate from the vehicle, thus reducing the vehicle's weight and the costs inherent in excessive moisture retention within a vehicle.
Claims20
Vehicle insulation which comprises
- at least one insulation layer;
- a case surrounding the insulation layer to form an insulation package, wherein the case includes material which is liquid water repellent and moisture vapor permeable;
- wherein moisture vapor within the vehicle passes freely into and out of the insulation package, allowing condensate to evaporate away from the insulation.
An insulated vehicle, the vehicle having an outer shell, an interior, and an insulation package mounted between the outer shell and the interior of the vehicle, the insulation package comprising:
- at least one layer of insulation material;
- a case wrapped around the insulation material to form the insulation package, the case comprising at least in part a material which is liquid water repellent but moisture vapor permeable;
- and
- wherein moisture vapor contained in air within the interior of the vehicle passes freely into and out of the insulation package but liquids are prevented from passing through the case.
