But that is an expensive solution after you have built. Here is something from 3M... Ed 3M™ Scotchtint™ Sun Control Films are designed to reduce the amount of solar heat transmission through window glass by increasing the solar reflection (not necessarily visible reflection) and solar absorption through the glass. Typical colored or dyed films work primarily through increased absorption. The color absorbs the solar energy at the glass, thus reducing the direct transmission into the room. These films are not as effective as reflective films for reducing heat. Reflective films are films that have been precision coated with metals. These metallized films are designed to increase the solar energy reflection of the glass. 3M™ Scotchtint™ Reflective Films range from moderate to excellent in solar performance (heat gain reduction). All 3M™ Scotchtint™ Sun Control Films are made to be transparent and optically clear. The ultraviolet protection in the adhesive system is there to protect the adhesive, the metals, the polyester film, and the abrasion resistant coating from UV degradation. This UV protection will also help protect home and office furnishings. Most 3M™ Scotchtint™ Window Films are protected with our patented abrasion resistant coating that provides long-term durability and maintained appearance. Not disputing that films will work somewhat to keep out radiant heat . However double glazing will do nothing to stop direct sun getting through the window. S has been said by others you need to keep the sun off the glass. What has not been mentioned is if the wall is insulated or not? It might be a bit darker in the mornings but the light is still light, so you should be getting it. Similar to what you see from your western windows 3 19992 The warning is on the sticker on the door too.
