TWL: When stored upright (with the end/back LP resting against a flat board) I have never experienced damage. I grew up in Iowa (no A/C), before moving to LA. Still don't use A/C (even removed one from our apartment as I hate the stuff in my home). The main problem comes from not having the back LP resting against a loose flat vertical surface that moves with the angle of the LP cover. Inserting a few more flat boards, in long runs of LP's, would probably be a good idea as well. Never had mold occur in living quarters, just basements and crude garages (not on a slab).
Are records harmed from no air conditioning?
I have a house with no air conditioning. The temps sometimes reach low 90's. Will my records be harmed by these temperatures? I am keeping them out of the sunlight. Is there a known temp that vinyl can handle without warping or damage? Is there a storage method that is advised for warmer climates w/o air conditioning? Or am I worrying about nothing? Any help would be appreciated. Thanks.
