The lowered sill of balcony doors

Instead of the standard version height ca. 100 mm it is possible to use the lowered aluminium sill with balcony doors. But from the tightness point of view this version is not a full-value replacement of the standard sill. Therefore it is not convenient for the environment with increased snow and rain load.
