Continue by adding one more P3 – P4 couple.
On the two flanks of the vent (see arrows in
drawing), slide two different aluminum profiles, namely profile
A14/325 on your left and profile A14/600 on your right (as clearly
shown in the drawing), until they are positioned at the top of the
existing aluminum profiles below them.
IMPORTANT – Note that the top of aluminum profile A14/325
is slanted. When installing it in the structure, take care to have
the lower top point positioned on the left (as you see it, namely
towards the completed side wall of the structure).
