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.
