This sail is of marine quality, the customer chose the high-end waterproof and breathable so as not to retain heat in summer
The posts are made of 45° aluminum, it is possible to have posts of different inclination and height, fixed to the ground, directly to the wall
For this sail, it was chosen with the aluminum wall profile which gives better wind resistance (up to 60 KM/H) and total protection up to the wall.
The advantage of the sail is the price compared to a quality roller blind. And most importantly, the wind resistance that no blind has.
