What exactly can you NOT blow up with C4? I put 2 C4 on my wall and it didnt blow up? But doors do?

So in game Ive heard people saying it takes 2 C4 to kill a metal door, 1 C4 for a wooden door. But what about walls, and roofs? Can they be blown up also? If so, how many C4 blows them up?

Im trying to figure out the best way to go about building the safest house possible.

floord and roofs is pointless, but walls are easy. A good defended home can be breached in 10mins with ease. So its pointless to acually have a home in rust.

[Kottos]

Wood door = 1 C4 / about 200 stone hatchet hits / about 150 hatchet hits / 95 pickaxe hits
Metal door = 2-3 C4 / 10 F1 granades
Wood wall/doorway = 2-3 C4 / 10-15 F1 granades
Metal wall = 6-8 C4 / no clue how many granades
Pillars, ceilings and foundations are indestructable.

I have no idea where you learned some of these figures, but they are not correct :x.

K so wood door is as said 1c4.
Metal door (brand new with no decay 3 C4) standard metal door 2 C4. (12 grenades new, 11 otherwise)
Wood wall if C4 placed correctly 1 C4. if not 2 C4. (11 grenades is placed well)
Metal wall if placed correctly 3 C4, if not (dont know how many if placed poorly)
