CONCRETE ROOFS
TEST ENVIRONMENT CONDITIONS• Roofing temperature : + 80°C• Air temperature: + 25°C• 10-hour exposure. Any heat loss in the area below is not considered• The same insulating material, of the same thickness, has been used in all tests
NON-VENTILATED ROOF
VENTILATED ROOF
THERMAL RESULT
•Temperature of the plastering after a 10-hour exposure = + 34.5°C • Kcal absorbed : 450 per sq.m. of roof
• Temperature of the matchboards after a 10-hour exposure = + 27.5°C• Kcal absorbed : 100 per sq.m. of roof
