I have been giving the windows a lot of thought, they let in a huge amount of heat when the sun shines on them and they let a lot of cold intrude in the winter. I am going to actively pursue getting an estimate to have 3m Thinsulate window film installed on the inside of the Solitude windows. Hopefully it doesn't brake the bank. Since summer is around the corner, it would be nice to not have the extreme heat gain from the windows. I have foil bubble wrap cut for most of the windows, but to be honest, it blocks the view and is only marginally effective since it is not sealed to the windows.
