We had a few screens out over the summer for the duration of the FIFA World Cup Football 2018. The largest one was built in a well known Hotel at Dubai Marina. This was outdoors, on the beach, working daily in up to 50 Degrees !! We custom built a support structure and placed some temporary air-con in the rear of the structure. This worked well and the screen ran for the duration. this was our 4.8mm outdoor screen.
