Block family resistance to Redstone

A family of blocks that isn't affected by Redstone would be very useful. Perhaps a special type of stone or non-conductive metal For example - full blocks that don't pass redstone signal from repeaters/comparators/etc or redstone on top (like glass) This family of blocks would also have a Door, Trapdoor and Fence Gate variants that can only be opened by hand, and not affected at all by Redstone.
