My wife have some huge single-pane south-facing (and in southern
California, USA, Northern hemisphere, that means "towards the sun")
windows that will most definitely get replaced when we replace all the
energy innefficient windows in our house in a couple years. We are
stalling on that project because it will be very pricey, I am sure.
We do have curtains to prevent the light from fading furniture, but I'd
also like to coat these windows with something to help block out the
UVA/UVB rays (not sure of the difference) when the curtains are open.
I know there is film material you can cut and apply, but I feel our
circumstances (huge oddly shaped windows) might make that a difficult
project to accomplish satisfactorily. I was wondering if there were
any "paint on" type of liquid which dries sort of clear and smooth and
yet provides a coating which blocks some rays. I would prefer to do
this myself rather than have a professional do it. This windows will
probably be ripped out in the not terribly distant future, so I don't
want to spend tons of cash on them.
As always, I am certain that I am imagining the existence of a miracle
product that does not exist, but if it does exist, please let me know!
