Excellent point about getting styrofoam for free (I hadn’t even thought of that). With that in mind, the only cost would be for time spent gathering the foam and then covering the fridge (I could probably do this in less than an hour, tbh).
Thanks for this comment!
Very cool post (pun intended).
This got me thinking about the goal of this kind of insulation…
If it’s cost savings, what would be the timespan until the cost of the styrofoam is paid for by the energy savings? ( I have no idea what that type of styrofoam costs).
If the goal is environmental, how much energy savings would be needed to offset the footprint of the manufacture of the styrofoam and transport of the styrofoam to your location?
In either case, I’d have to assume the less efficient (and older) the fridge, the faster you’d make the extra insulation pay itself off.
Holy shit this is some #theydidthemath stuff.
6 months at paying full price for the foam is a ridiculously quick turnaround given the lifespan of a fridge (easily 5 years). Plus, you can probably reuse the prior fridge’s foam on the next fridge, so that makes it even better.
Why don’t people do this more often? If the gap in my current “fridge space” wasn’t so small already, I’d be tempted to go find some foam.
