Fully glazed vs glazed with midrail - can't decide

[hauntedicecreamvan]

I'm planning on fitting a fully glazed aluminium door in my porch to let more light in the hall. I want the door to be glazed full height but can't decide between a single large glass panel or two panes with a midrail separating them. Adding the midrail adds a significant cost to the price of the door, but I'm not sure if there are any real benefits. I don't need to fit a letterbox slot.

 

The fully glazed I assume wins on thermal and acoustic performance, having just a single pane.

 

I assume that the midrail would improve the integrity of the door, but given that it's aluminium, how much does that matter?

 

There's also the argument that if the bottom pane gets broken, there's half as much glass to replace, but then would I be able to get the same glass to match the top pane anyway?

 

The midrail seems to win on security too, because if you smashed the full pane, you could push it out and step through, whereas the midrail glazed door would require crawling through broken glass.

 

Any thoughts welcome.

Full height glazed, with laminated glass. You wont break it. A midrail will make it look like a back door.

Thank you, this is what I went with in the end. Looks fantastic in the slim profile aluminium frame.

@hauntedicecreamvan Which door did you go with? I'm currently looking for a fully glazed door.

I went for fully glazed, from Just Value Doors, who use Smart Systems profiles. Very easy to fit, and there is a small adjuster on the top of the door in case it ever needs the toe and heeling adjusting without taking the beads off. I went for 6.8mm acoustic laminate plus 4mm toughened glass which was a custom order but I found them helpful to deal with.

 

My only criticism is that if the handles ever need to be replaced, there aren't a lot of options, because standard 32mm wide plates don't fit due to the narrow aluminium profile.
