That's not exactly true. To the degree that a standard tinted film does nothing, yes that's true. But the films designed for residential and commercial windows have a stated U value and heat gain coefficient. The 3M P70X allows 70% of light to pass through, has a U value of 1.02, a heat gain coefficient of .48 and claims to reject 52% of total solar energy. I've really got to get this stuff bought and installed. It'll be fun checking floor and furniture temps (I have a sickness) to see what good it did.
Oh... and yeah a home energy audit is a wonderful thing. It helped me find where my worst air leaks were coming from and address them. I now have a home that is over 100 years old sealed to the minimum building standards of today which seems pretty good for an old home.
