I have just moved into my wifes house which is an old style double story wood thai house
we live in the top part and the main living area has a metal roof this has 4 metre between floor and roof
On a Warm day the temperature gets to 40 by 11 I put a thermometre on a rafter which was about 3 inches
from the roof it was 50 the living area is 40 ft x 15
Has anybody out there got any suggestions for cooling this place

Thanks
