Hi,

I live close to Phoenix (AZ) where as summer temperature can go as high as 115 degrees and sometimes even higher.  My house has a south facing slump block(http://www.airvolblock.com/cm/Masonry/Masonry_Slump.html) wall (28ft X 8ft) that turns into a heat sink as the outside temperature reaches 90 degrees. There is no insulation or drywall whatsoever on the inside.  I as looking ideas that can be applied to the outside of the wall so as to reduce the amount of heat that penerates the wall?  Thanks!

James

Look into a white or even reflective metal rain screen mounted on wood or metal studs giving you an air gap between the wall and the rain screen panels.

I suppose insulation under the rain screen would also help.

......or a portico, or even a canvas awning to shade the wall.

(thanks for the Greenrooftops link....I had not seen them before)

The slump block is hollow on the inside and years ago I had a contractor inject foam into the blocks but that did not help much. I feel applying reflective paint will have the same effect. However, thank you all for your suggestions on rainscreen, green wall, and awning. I will look into it.

External insulation would be an option.
