Now a day the weather is very hot. Even though I am using Rockwool to insulate my roof, I find my average temp reading is around 29degC and max is 31.5degC. Maybe the Rockwool's density that I used not high enough, I decided to try Heat Insulator Paint.
The roof temperature can go down to about 8degC. I hope the BH average temp can go down to 28degC. I will post the data logger reading once I go back this weekend.
If you interested on the Heat Insulator Paint, please email me... cheinwoei.gee@gmail.com
Hi, I found that Heat insulation paint works best with cement surface, not to steel roofing. Maybe you have to increase the air flow between roof and ceiling. Thank you
