We're looking for ways to up the energy efficiency of our building. We've looked at the typical options, but we are also exploring some more unconventional routes. We happened upon a product named Sketchnanogard, a window insulator that claims to drastically change window heat gain/loss. 

What can you tell me about it? Worth the investment?
