As wearing armour under void suits might not be feasible, did you give your PC's Selentite Pattern Heavy Duty Void Suit?

In my game there are a number of options. There are the armored void suits that are awesome. There are really nice void suits that you can wear loose fitting armor over (so a mesh cloak is fine, but no carapace). Then there are bulky oversized suits, sort of like our current space suits, that can be fitted to let you wear armor under them, but your movement in them is... kinda horrible.

What the players get access to depends on their foresight and the situation. For Twilight, given the importance of the mission and proxomity to a well equipped Hive, the players would have access to the very best, in my game.

Same here. I gave all but one of the group armoured void-suits or something equivalent. The remaining one was a Sororitas character who had just entered the Sister Militant rank, so she got to wear the suit of Power Armour her Order loans her, complete with Sabbat-pattern helm.

I clearly remember that (written in the old IG Codex) the MkIX-gasmask for the IG can be fitted so that they can be sealed completely from the outside, making them void capable. A Guardmen in full Flak with said gasmask can, with the necessary extras (gloves, magboots, oxygenflask, ...), operate in the vacuum of space, if only for a short time. Same would logicaly apply to the Stormtrooper Carapace, but logic and 40k are not always compatible ^^.

Since the Naval soldiers (on the battleships) are most likely as well/lousy equipped like their footslugging cousins it would make things easier for the Ministorium Munutorium. Only add special gloves and boots, and they can fight in space, board other ships, secure space hulks.

"Void Capable" is an option I allow to be added to any full-body armor suit, but they are not generally as safe or reliable as an actual void suit. So if there's just a risk that you might get exposed, a void capable Storm Trooper Carapace suit would be perfect, but if you expect extended periods of time, or worse actual combat, in the void, you'll want something that won't kill you with hard vaccum the first time you take a bad hit.

I was going to give my players the option of using the armoured boarding suits from the Inquisitor's Handbook, but they instead decided to wear armoured bodygloves and mesh armour underneath the void suits.

I'm unclear on the benefit of wearing armor under your space suit....

"Well the good news is that mesh armor saved his life, unfortunately all the air vacated through the hole in his void suit"

(of course I don't have my book in front of me so I'm probably forgetting the part about self sealing materials)

Get them something like a space activity suit to wear under their armour.

You said it - a proper (=expensive) void suit will firstly be capable of limited self regeneration and secondly likely have a "bulkhead" system in place that seals off compromised compartments, just like a ship does (not too helpful when applied to a head shot, but oh well...).

I'd say the primary benefit of armor under the void suit is for all the times you end up fighting when not in the void. Otherwise, you're taking a big risk no matter what you're wearing, fighting in the void.
