Do multiple sources of "Defend with X% armour" stack? And with ele armour?

I couldn't find an answer how these interactions work together. Let's say I have talents Reinforced Barrier and Blade Catcher. I have my energy shield and I'm getting hit by a phys crit. So, how much of my armour is applied to it? Is it the highest of both (200%) or is it cummulative, so it's 320%?

I also wonder how it works with "X% of armour is applied to elemental damage". Let's say I have 150% of armour is applied to ele dmg in my build. So, I'm getting hit by an ele crit when I have my ES up. Would it treat my 150% to ele as my base armour, so it's then multiplied by "Defend with X% armour"?

I found an answer. In the first case it would be 220% armour. In the second the answer is yes, "armour applied to elemental damage" basically multiplies base calculated armour, so it would then get multiplied by "defend with X% armour"
