I will be using one way glass with triple pane argon filled windows. This will provide for the best R-Value for the window therefore keeping the interior temperatures indoors. The one way glass windows will allow people on the inside to look out, but those on the outside will only see their reflection if they peered into the window. This will actually mean you do not need curtains to cover the window. This will allow light to come in, and therefore less of a need to turn on the lights. This will hopefully save money on the electric bill.
