I am assuming by "distance", you mean how far in ohms are they in the spectrum. Or if you meant difference, I guess this answer will address that also, I hope.

That's an interesting but difficult question to quantify - I googled a bit but surprisingly, not much clear standard for it.

And I guess there are many reasons for it. While instulating materials aren't perfectly dielectric as they should be, they still are mostly evaulated based on breakdown voltage - basically until that point, there is assumed to be no current flow at all or very very very little that you can ignore (well, let's just talk about DC here - AC, obviously, this isn't true but then you'll be talking about capacitance and not resistance/insulation).

Because they just really don't have a way to conduct electricity unlike the conductors or even semiconductors.

That said, here is the copy paste from wiki (http://en.wikipedia.org/wiki/Electrical_resistance)

Material Resistivity, ρ ohm-meter
Metals 10 ^-8
Semiconductors variable
Electrolytes variable
Insulators 10^16

I guess that is a huge gap. But from what I remember, semiconductors can defintely sit pretty close to the metals (atleast, logarithmically speaking, just in an order of 2 or three) so, I guess you can assume it is almost like resistance stops at appx 10^-5 ohm-meter and insulation should start around 10^15.

Also, look at this page, just for a bit of reference:

Hope it helps.

Resistance is the opposition to current flow measured in ohms.
Insulation or an insulator is a nonconductive material used as a separator between 2 conductive materials.Ex. rubber & plastic would act as insulators

Insulation is just stuff that has high resistance and is used to wrap conductors so they don't short to each other and things. Resistance is what you get on Saturday Night after the movie .

Not so sure bud, but in high voltage transformers, oil is used as an insulator...it can contain a couple of KiloVolts per millimetre...Resistance to oil? Not so sure..many possibilities!

something will strengthen mould. Is there any thank you to place a dehumidifier below there? If no longer, you could desire to placed a vapor barrier up. placed the insulation up then staple plastic as much as maintain the moisture out.
