I can’t keep the heat in.
I live in a house built in the late 70 to early 80. It is approx 1600 sq feet and I was wanting to know if it would be more beneficial to replace the aluminum single pane windows with new ones or to invest in a window film to help with the winter months. During the summer the electric bill is not bad, due to a very shaded property, but in the winter months it goes through the roof.
