Thermal bridging around windows

[gc100]

Hi,

 

I'm looking at my architects drawings and it seems to my untrained eye that there is a pretty bad thermal bridge around where the window meets the exterior brickwork. Would there not normally be some form of insulation between the brick and the window frame??

Aluminium or plastic windows often have a thermal break between inside and outside parts. Outer frame in contact with external building skin. Inner frame with internal building skin.

It looks like something breaks the join, assuming outside is at the bottom or the image, a little, those squares (x) in the corners or is that just the mastic? Either way it does not feel like a robust detail.

I think this is a Velfac or IdealCombi composite window.  Ideally you would have the glazing near the insulation layer but I don't think that will work with the brickwork.  Just make sure you foam between the frame and the timber cavity barrier.  You should also tape between the window frame and your vapour barrier to stop air leakage.  The window manufs may have a detail / spec for this.
