My new house has a few big windows facing southwest, taking much sun heat in
the afternoon. Have to keep the heat pump working till after midnight to
I went to HomeDepot and hoped could find some kind of window film that can
block sun heat - something like we put on minivan window glass. But there
are only some small packs of decorative films available there. Need some
advice on this.
Any place that does auto window tinting should be able to sell you
some. You may want to consider having them do it. If done wrong it
bubbles and looks really ugly. We had all of the windows in our house
done by one of the local firms 10 years ago and they all still look
good. Be careful what you wash the windows with because some cleaners
are not good for tinted windows and will weaken the adhesive.
Many films, and pretty much all of the professional film, does not
have a backing. The bubbles are trapped air. The instructions will
specify how to minimize bubbles and what to do when you can't slide
them out to the edge.
I watched the guy applying the 3M film on our patio single pane windows.
It comes many different shade and color.
No backing for sure. On a clean glass, he thinly applied ivory gentle
liquid soap put on precut film sheet and squeeze out over and over until
there is no bubbles. just few minutes effort. Just like hanging wall paper.
I live in Florida and have two rooms with windows facing west. I
bought some window film at Home Depot several years ago and put it on
my windows. It looks like what you see on cars. It wasn't too hard
to manage. Clean the inside of the windows real good before you start
- as I recall there were explicit instructions on the box. Go back to
HD and ask again - I am sure they still have it. It sure down on the
heat that was coming through the windows. That was about 10 years ago
and it still looks fine. You can see out but people cannot see in.
That few minutes of effort came after a lot of practice. The pros make
it look like a piece of cake but the application frustrates a lot of
It's like welding. It's like ANYTHING. After you do it a couple of
thousand hours, it is easy and looks easy to an onlooker. And I don't care
what it is. Even brain surgery.
If your windows are double pane sealed units, check out the warranty on the
glass. We recently changed our windows and in the process of doing research
for the project discovered that all the manufacturers available to use
voided their warranties if a film was applied to the windows.
Film isnt going to do it..Didja notice that even though cars have tinted
windows, it still gets to be 135 oF in there in the Summer sun.
We hung some "roll down" shades outside the glass (white plastic tubes from
Big Box stores, sort of like Soft drink straws (shaped like 0 ).
We roll em up after the sun has passed by. It cut our "inside" heat WAY
We already had these "inside" but found that once the heat comes "in" thru
the glass, the house temp stayed right up there..
All the venetian blinds do is channel the heat UP to the top of the window,
then out into the room. They do help in Sun damage/fading.
There are rolldown "Sun shades" /sunchasers (like the ones on Larger RVs)
that even have remote controls.
Just make sure that whatever you get, is on the OUTSIDE.
If they are dual pane you will void many companies warrantys, the
interior pane heats faster and can crack in certain situations like
when the sun comes up when its real cold out and the panes expand
unevenly. I cracked a few. Research it first or better yet have a
local glass co do it that guarntees their work.
Those films known to damage the glass(cracking) from heat build up.
It happened to our window. S/W facing double pane window suffered damage
and window company wouldn't honor warranty finding out film was
used. Single pane windows are OK. Since we upgraded to low E Argon
filled double pane windows. Single panes on my sun room still has films
w/o any problem.
