Anyone use this heat-away thermal shield before to reduce the temperature of the house? It claims it can reduced by 7 degress celcius. Is that true? The material looks like car wind screen shield but maybe different materials..
Any experience please share...
Reduced by 7ºC - Room Temperature or ceiling inner surface temperature or Roof inner surface temperature or...?
I don't think is the room temperature. Lets assume Malaysia average temperature during 12pm ~ 4pm is 32ºC, if room temperature reduced by 7ºC means the room temperature is 25ºC without air conditioning!
I believe that they must refer to the roof inner surface temperature not even ceiling inner surface temperature.
