WOW, I couldn’t believe it a 13.1 degree difference.

Today I decided to do a test, to check the efficiency of a 2 inch covintec panel in the real world vs the sales pitch. I already knew it was good but never expected this.

I had the time to do a test, with a laser temperature to gun, to check the efficiency of the covintec panels in direct sun. The wall in question is my west wall, so it gets the afternoon sun but not all day sun. I knew the panels are good but never expected this. The sun had set by maybe 10 minutes and the ambient air temp was 25 degress C. Outside wall temperature with the gun on bare mortar  wall 37.7 deg C.  Same spot on inside wall 24.6 a whopping 13.1 degree difference, that is a lot less energy required to cool a room, if you are using Air-conditioners. This is with a 2 inch Covintec wall panel. The roof is 4 inches so should even be better in the full sun all day.
