Looks good, Dave...
We habe a roller shutter door.
It faces South East.
It is dark brown wood effect.
Although the cores of the slats are foam filled, it still gets hot in summer, the IR Oven thermometer recorded 40c...
No obvious solution, as far as I can see!!
So it is often left with a 10cm gap underneath...the cats appreciate it. Secure enough, it cannot be lifted as there is some sort of anti lift device. I was told a fork lift truck could force it up....
