making hollow core doors solid

I need a few brand new doors as I finished my basement area and noticed that slabs made with hollow core are as cheap as $35, while solid doors are way more expensive....close to $100 (in the design I like)

Do you think it would be possible and feasible to simply shove a lot of Roxul Sound'n Safe insulation between the panels of the hollow core doors, since I will have to trim them to my specific size anyhow... ?

I only need that for 2 doors and already have some left over Roxul insulation.... would buy doors, trim on the bottom to my desired height and stuff it with the insulation.

What you think ?

No, I don't think that will work. Most hollow core doors are not totally hollow. They have a cardboard/paper honeycomb core. If you drill a hole or knock a hole you will only have access to one cell in the honeycomb. If you want a solid door it's best to buy a solid door.

If you've ever cut down a hollow core door you'd understand why that won't work. Any special reason you need a solid door? IMO masonite doors paint up nicer than solid wood panel doors.

If you must cut down a hollow door, you must remove the top or bottom rails, cut the skin and re-insert the rails. And as the others have said, you cannot fully insulate a hollow door.Name:  Capture.JPG

It's a lot quicker/easier to rip a new bottom rail than it is to salvage and reuse the factory one! I rip a 2x to fit.
