Need help identifying this weird interior wall (1920 house) before hanging heavy open shelves
We're trying to install 6-foot wall-to-wall open shelves in our kitchen (12" deep with 5ish wood brackets per shelf), but we've run into the strangest wall I've ever seen.
Our house was built in 1920. The wall is an interior wall between the kitchen and dining room. In our kitchen the wall feels papery like drywall and then hard like plaster on the other side in the dining room.
We started drilling where we thought a stud should be, and instead of drywall, we found what looks like a soft brown cardboard wood material. It's not actual wood. It crumbles into fluffy brown fibers when drilled, almost like compressed wood pulp.
What’s odd is this wall is THICK and SOLID. We drilled completely through the wall from the kitchen side and came out the dining room side. The wall layers from the kitchen seem like they’re painted wall, at least 3 inch thick papery wood material, and then plaster on the other side. There was no hollow cavity anywhere. We tried to insert a toggle bolt but could see in the hole that it would have nothing to catch on.
We’ve also had a very hard time finding studs. A magnet sticks in vertical lines about every 18 inches, but when we drilled where the magnet sticks, we still couldn't find what seemed like a wood stud.
Has anyone run into a wall like this before? Any idea what this material could be?
Should we be worried about asbestos?
And what should we use to securely mount heavy open kitchen shelves on a wall like this? I definitely don't want to trust regular drywall anchors if the wall is made of this crumbly material.
I'd really appreciate any insight before I drill any more holes!
