Are Composite Windows airtight when you use them for both wall and ceiling?

[robcreid]

I tried to design a glass/tunnel house with glass ceiling and glass walls on the sides facing sunset/sunrise. I could not get it to hold pressure.

Switched to glass ceiling only and it is working ok but I'd like to have optimum sunlight time for my plants.

Is there a known issue when you combine Composite Windows for walls and ceilings?

I've seen a few posts about air loss. Happens on Beta also. I hope it's fixed soon.

I have been running glass on the east and west and top of my greenhouse with the north and south walls enclosed steel block. I have not noticed any gas loss. Or it is so minor I just haven't see it.

It may be on new structures and yes, all steel and iron structures are air tight, except for slopes and corners.

I have used composite windows and didn't notice any air loss.

It might be a bug with the room generation because I had an issue where gas from one room was leaking into another through the windows (volatiles from an automated furnace room). After stripping it down and replacing it, it was no longer leaking.

I built a greenhouse with east/west facing glass and a glass ceiling. No air leaks at all.

Make sure that you're placing the composite windows on the correct side. There are two halves to every wall. Place the windows on the inside of the room.

Scroll your mousewheel while holding a composte wall. Add iron sheets(don't know why it's iron sheets when a composite wall requires steel sheets) then add a glass sheet.
