I had an aluminum entry door, thickness 5 cm, lock 3 points, model Janella 25 glazed V2.
The summer from 8 am to 11 am this door is exposed to the sun, it becomes impossible to turn the key in the lock, the door undergoing a dilatation of the order of 2 to 3 millimeters between the middle and the top of the door (80 cm).
When the door is in the shade there is no play and everything is working normally. Limer at the level of the penne would involve the game and the passage of air, in condition of shade. The installer finds no solution outside the image.
Do you have a solution to this problem?

Such dilation is not abnormal, although it is not normal that you suffer such a malfunction.
In practice, it is necessary to adjust the penne at the hottest time of the day: the game should not be large enough to create a large air passage, because there are many joints around the door to absorb this game one.
your installer's proposal makes sense. Another solution would be to avoid overheating your door by having a awning installed above the door in question to protect it from the sun.
