Heat is one of the few things that can permanently ruin a record quickly. Vinyl softens at temperatures that a sunny window, a hot car or a top-floor flat in summer can reach. If you live somewhere hot, or in an apartment without reliable cooling, a few storage choices make a big difference.
Why heat warps records
Vinyl records are made from PVC, which softens as it warms. A record does not need to melt to warp; uneven heat (for example sun on one side) or pressure while warm is enough to make it bend or dish. Heat can also make shrink-wrap contract, squeezing the jacket and the record inside.
Finding the coolest spot
- Interior walls stay cooler than walls that face the sun.
- Low shelves: warm air rises, so the bottom of a room is often cooler than the top.
- Away from windows: even indirect sun through glass heats jackets.
- Away from electronics: amplifiers, fridges and TVs give off warmth.
- Not on top of the turntable cabinet if your amp sits inside it.
Store records upright and snug
Records should stand vertically, like books, with enough neighbours that they do not lean. Leaning records bend over time, and that bending happens faster in heat. Stacking records flat in tall piles puts weight on the bottom records, which can warp them. If a shelf is only half full, use a bookend or divider.
Sleeves help but do not cool
Outer sleeves protect jackets from dust and ring wear, and inner sleeves protect the surface, but neither insulates records from heat. They are still worth using, as hot rooms are often dusty from open windows and fans.

Shrink-wrap in hot weather
Many collectors slit or remove the original shrink-wrap so it cannot contract and squeeze the jacket in heat. If you want to keep it for collectability, slit it along the opening edge and store the record in an outer sleeve.
Moving and transporting records
- Never leave records in a parked car, even briefly on a hot day.
- Carry them upright in a sturdy box, not flat at the bottom of a bag.
- Let records reach room temperature before playing after transport.
Warning signs of heat damage
A warped record wobbles visibly on the platter, makes the tonearm rise and fall, or sounds "wow"-like (pitch drifting). Slight warps may still play; severe warps can cause skipping. Don't try to flatten records with an oven or hair dryer; uneven heat can make things much worse.
FAQ
What temperature is too hot for vinyl?
There is no single safe number, but many record-care sources recommend normal room temperature and avoiding anything that feels hot to the touch. The risk rises sharply in direct sun and enclosed spaces like cars.
Should I store records in a closet?
An interior closet can be one of the coolest places in an apartment, as long as it is dry and not next to a water heater.
Does humidity matter too?
Yes. High humidity can encourage mould on jackets and sleeves. Good airflow and clean sleeves help; see our inner sleeve guide.
