Cellar window cover

Protects heating oil from too much cold

Since heating oil paraffinises at subzero temperatures (last winter we experienced -20 degrees!), my heating specialist recommended to seal my cellar window (where I store my heating oil) in the winter.
I made a styrofoam board for that purpose and put 4 strong pot magnets type CSN-32 on it. This way, I can attach it to the metal cellar window. I attached two handles to the styrofoam cover, which makes it easy to remove. Thanks to the pot magnets, the cover attaches perfectly to the metal window.
Note from the supermagnete team: Our CSN magnets are not suitable for permanent outdoor use, because they will start to rust over time. An alternative could be 4x CSF-60 made of ferrite.
