I was typing my reply for a half hour, then lost my work, so here is the shortened version.
First, if you could share a bit about the layout of your house, it would be helpful.
By that, I mean, is it a split level, bi-level, ranch, etc…
Do you have a basement? If so, is it partially or completely underground?
I remember that thread you mentioned about resin and bullet proofing, and I wasn’t buying it.
My opinion is, for someone on a budget, sand is the way to go.
Believe it or not, roughly 6 inches of sand will stop a 9mm, .45, .223, .308, 12 ga. Slug, and even a hard-cast 510 grain 45-70.

All that stopping power, and that is without a hard surface up front to mushroom the bullet initially.
Sand is also an acceptable barrier to radiation, and doesn’t burn.
A regular concrete block, available from any home improvement store is 15 5/8 inch long, and I’m guessing the studs in your home are spaced 16 in.
A roll of plastic thermal barrier is cheap, and will help prevent the spilling of sand, as well as set you up for a plenum chamber type
air filtration system.
Here is a Link
that goes a bit more in depth.
This filtration system basically keeps the air pressure (filtered air) within the room at a higher pressure than outside the room.
The downside to this is the space required, hence my curiosity as to your home’s layout.
With a bit of research, scavenging, and using your own labor, you can have a handy little space for several hundred dollars, depending on what you
have to work with, space wise.
