heat film on windows
bunny
would be economical for me. This film is in contact with the window and
blocks light energy from passing. In the summer, radiant heat from
outside is cut down and the house is kept cool. In the winter, heat is
kept in the house because it is not allowed to radiate out.
This seems like they're not telling the whole story. Sunlight radiates
in during the winter as well and I think this is greater than the heat
radiating out.
So cooling costs in the summer would be lower, while heating costs in
the winter would actually be a little higher. The reason I think this
might not be economical is that I have no air conditioner in the summer
and I heat my home with electric heaters in the winter.
Is my reasoning correct?

Please do not ask identical questions in different newsgroups. You
are allowed to places a post on up to 4 and sometime 5 newsgroups, all
at the same time. That way, you can get input from lots of people and
corrections where needed.
The films do exactly what they propose to do, and they have a short
lifespan.
