The awnings keep their promise. The heat is actually out there and it is not pitch black in the room. The sun is about 3 hours in the morning on our bulging 3 velux rooflights and heats the room at this season min. 10 degrees. With the awnings little heating of the room through the direct sunlight is perceptible. Only the hook in the retaining claws is with large windows only on tiptoe.
The installation of awnings is done very simple and in 5-10 minutes. Matching screws for fixing the retaining claws and the appropriate hexalobular bit (Torx) is included directly.
