Anyone knows if the gap between the window and metal lintel is intentional and what function does it serve? I guess it helps to vent any dampness. The house builder had filled the gap above the back door with mortar. The gap above windows were left open. Any problems for me to seal that? It will help a tiny bit with thermal and sound insulation. Thanks.

It's a cavity weep vent above the lintel - don't seal it, or you'll get damp issues.
The detail looks something like...
...or have I misread?
Sorry, you mean the gap between the frame and the lintel, which can be filled.

No answer suggests the gap is permissible and probably useful during construction to help drying the window area. It's not so great post construction since the gap allows outside air to come into contact with the back of the plasterboards in the window recess. It is still useful if there is risk of the window timber getting wet from leaks. I am taking a gamble and sealing it.

Hi, I think what you did looks great, well done!
Would you mind sharing what material you used to fill the gap, and how you achieved the same colour (with the existing mortar)?
I have a similar gap to yours (ie. between top of UPVc patio door frame and bottom of metal lintel) and I plan to use expanding foam in the hope that it will help with heat and noise insulation.
What I am trying to decide, is whether to use silicone or a mortar mix to then seal the expanding foam.
A couple of photos attached: the first shows the gap (and on the right, the edge of the previous mortar), and the second shows the previous mortar that cracked in places and I have now removed completely.
Many thanks,
Sol
