Yes it would. Extruded (tiny bubbles, no beads) polystyrene runs about R5 per inch, compared to R3. 5 for fiberglass. If it is old enough to require rust repair, it may be time for a new fridge.

Can you replace refrigerator insulation?
Replacing the insulation on your refrigerator door can save you a lot of money on repairs in the future. The insulation or gasket can keep the door shut tight and increase the efficiency of the unit. New insulation can save you money and help reduce the chance of food illness from inadequate cooling.
How do I increase circulation in my fridge?
Make room around—and inside—your fridge.
Refrigerators need room to have good air circulation. Make sure there are at least two inches of space between your refrigerator and the walls around it. Likewise, a fridge needs airflow inside to keep food cool, so make sure you don’t pack items too tightly on the shelves.
What does insulation do in a fridge?
Thermal insulation is the method of preventing heat from escaping an enclosure or from entering the enclosure. In other words, thermal insulation can help keep an enclosed area such as a building warm, or it can keep the inside of a refrigerator cold by slowing down the transfer of heat.
What type of insulation is used in refrigerators?
Rigid polyurethane insulating foam
Rigid polyurethane insulating foam makes a major contribution to sustainability and eco-design by reducing the energy required to keep refrigerators and freezers cold. Polyurethane rigid foam is the insulating material which is most widely used throughout the world for refrigerators and freezers.
How do you Remagnetize a refrigerator door?
To do this method, find a magnet with a strong coercive force, such as a neodymium magnet. Run the magnet on each portion of the gasket 50 times in the same direction. The magnetic strength or current of the neodymium magnet will “recharge” the rubber seal to bring back its sealing property.
How do you insulate a refrigerator door?
Quote from the video:
Quote from Youtube video: We suggest putting strips of masking tape over the entire lid top so that when you turn it upside down and start working you've protected it from getting scratched.
How thick is the insulation in a fridge?
Mandated changes in refrigerants are resulting in colder line temperatures, which require increased insulation thickness to prevent condensation. In typical conditions, a 1-inch thickness is the standard; however, in some cases where humidity is high (over 80 percent), a 1½-inch thickness may be used.
Which of the following is cause for an increase in insulation?
7. Which of the following is a cause for an increase in insulation? Explanation: Generally, as the thickness of material increases, the rate of flow of heat decreases due to which the insulation takes place.
Should there be Styrofoam in my refrigerator?
Many refrigerators have styrofoam around temperature controls, vents, tubing, and other components, which acts as insulation. It is not packing material and should not be removed.
Which material provides good insulation from the cold?
Two common materials used in cold insulation are: Polyurethane Foam: Perfect for handling low thermal conductivity and substances with below freezing temperatures. Polyurethane foam also allows for low smoke emission and low water vapor permeability.
What material is a fridge door made of?
The cabinet and door are made of aluminum or steel sheet metal that is sometimes prepainted. The metal is generally purchased in a coil that is either fed directly into the manufacturing process or cut to size and fed sheet by sheet.
Why do fridges have metal doors?
If the freezer compartment is inside the refrigerator, it usually has a thin metal door to keep the freezer separated from the refrigerator, and an inexpensive plastic fan circulates air between the two compartments.
How can metal help to close a fridge door?
Some fridges have magnetic material in the rubbery strips on the inside edge of their doors, making the doors stick to the body of the fridge when the doors are closed, helping to create a good seal.
What’s inside a refrigerator door?
Quote from the video:
Quote from Youtube video: And it has these valves inside of it that takes the freon gas that we already took out earlier today and it pumps it through these coils as gas.
