Oak glulam instead of green oak for framing a glazed entrance door?

[Smallholdertoo]

We have permission for a small 1.5 floor house. This is due to have some green oak framing internally (not structural) and an external oak framed door with a fixed triple glazed pane ether side. I want the house to be well insulated and airtight. I am therefore getting a bit twitchy about the green oak and am wondering whether I could use oak glulam instead as it would then be possible to glaze using aluclad softwood windows and door frames within the glulam frame to match the other windows. Yes i would lose some light but I would have less hassle in the longer term and better thermal efficiency.  Any thoughts on the concept and who I should get to do the work? The frame is 2.7m long and 2.1m high.

 

Has anyone done anything similar?
