"Hollow core" wooden door

What does "hollow core" mean? Have been getting different answers.
Last input from local hardware store says it doesn't mean there's nothing in there; it means door is filled with ?? something. What?
TIA

It's hollow. Typically it may have cardboard strips on edge, glued inside, to provide slight siffening. But basically, hollow means hollow. Usually it will be plywood or pressboard 1/4" panels. A hollow core door is only for light use, interior.
Then there's solid core, which usually mean filled with coarse particle board. It's heavier than hollow core and might block noise slightly better, but it's still no good for exterior use and generally pointless.
Then there are solid wood doors, which could be panel doors or staved wood. (Glued up pieces to make a solid slab.) In recent years, panel doors have been coming through cheaply made, with veneer over glued-up pieces. A panel door meant for interior (1 3/8") used to also be usable for exterior use where a 1 3/8" door is needed, but that's no longer the case. They delaminate with moisture exposure.
That's the selection for wood doors.

Hi, Except frame of the door so it cn be hung and lock installed, between two thin wood panels there is nothing. If you punch it hard enough prolly you can make a hole thru. They;re used for interior where fire risk is not a concern unlike garage access door

Also used when noise transfer is not a concern. Those plastic doors at the home depot offer little noise attenuation. I noticed that at my vet where the same type are used. I can hear everything.

Hollow core doors are essentially hollow. They have solid wood only where needed, such as where the lockset goes and around the perimeter of the door.
The middle of the door is only filled with corrugated cardboard glued to the front and back panels of the door to hold those panels in place so that they have some degree of rigidity to them. This essentially makes it impossible to refinish a hollow core door. That's because as soon as you start sanding it, the areas of the door over the cardboard are going to get sanded down more than the areas between the cardboard that will bend away from your sanding block. The result will be a ghost pattern of the cardboard inside the door when it comes time to staining the door. So, if you're ever in a position where you need to refinish a hollow core door, paint it instead of staining it.
Hollow core doors are only used for interior doors because they offer no security. Someone could literally punch a hole through the door to unlock it from the inside.

So learn to snip already. It's not the same as being snippy.

You're really getting snippy. But you're too stupid to post in a coherent format. Usenet illiteracy, it's for morons like you!
