I have several skylights in my house and although they are dual pane, they do not have any lo e coating on them and the heat is still felt coming thru them. I am wondering if it would be okay to add sun reflective film or sunscreen to them from the inside to help reflect the heat ? I am thinking that it should be okay but then I was wondering if it would reflect too much heat back into between the panes. Anyone with any thoughts to share would be appreciated.
