@MTB_Vince - non issue because we have sun screens on all windows; making it impossible to look into any window. In AZ, it gets 120+F so we need to really deal with the sun. I just converted a 10ft X 15ft screened in porch to an atrium last week; back yard is 115F and the glass wall (12ft custom slider & custom glass; argon gas, very, very low e) is cool to the touch inside. At 3:00PM in the afternoon (height of hot in AZ) the atrium is a few degrees warmer than the AC ducted great room adjacent near the glass without an AC duct in the room. The great room AC duct is in ceiling one foot from the 12ft slider going into the atrium from Great room. I use to hate living here in summer (2011) and this summer it is a pleasure staring out at the 120F afternoon in a very cool room with no AC ducts and remote controlled ceiling fan is not even necessary.
The paver path was to the old screened in door and we are re-routing that path for the outdoor grille on the side… a lot going on this summer.
I was going to add the sun screens to the glass wall and it is not necessary for heat blocking and I have no neighbors behind me and to the right. There is a park on the side of the house where the music room is so cranking my tunes is no issue. My wife put all these solar lights around as accents so it looks like a diorama or vignette at night, very cool looking out at the back yard at night.
The blanket is marking off where there will be a fire bowl with reflective crystals; RF controlled so we just sit back and scope out the back yard at night. I added an IR extender in that room to control the music room stereo with iPad too.
