Thinking of putting this screen in hot weather permanently. Will the screen get damage?

Like any other petroleum-based synthetic fabric, it is not advisable to mount this screen anywhere that receives direct sunlight for any amount of time. Also, cleaning the white screen is not easy so we would be wary of dirt accumulation. Finally, while the collapsing design of the frame is near genius, the frame itself is thin-walled aluminum and could suffer some damage from an unexpected stiff breeze, even after putting in place all the guy lines and stakes through the frame legs too.
