Reflective paint?
 

The front of my house faces the evening sun.
When it's 100 outside, the brown front door is 184 degrees F.
Stuck a square of white insulation board in front of the door.
It got up to 107 degrees.
The light-gray house is at 164 degrees.
I started thinking about painting the front of the house white.
Did some online research and found mention of paint that's highly
reflective in both visible and IR parts of the spectrum,
but nothing on where to buy it.

Most info was about coatings for roofing.

There's even some ceramic sphere additive that claims to
cut solar heat gain to near zero. Seems like if this worked
as well as they claim, it'd be everywhere. Went to big-box
stores and dedicated paint stores. Nobody heard of it.

Will repainting the front of the house buy me anything?
The walls are R19 and the windows are low-E R3.3-ish with SHGC of .3.
Door is fiberglass r5-ish.

Reflective paint recommendations?

Thanks, mike

the ceramic spheres are very costly since they are a realtive of space
shuttle tiles.

white paint will get you less heat gain in summer, but cut winter heat
gain too.....

you could reside adding a layer of foam insulation between the
existing siding and new siding, plus no more painting:)

foam board is around R6 or R7 per inch.

so you could double your wall insulation

The glass spheres are only a couple of dollars a pound.
Not sure I'd want to paint my door with them as it would look like a
road sign when headlights hit it at night.

A white door is artistically acceptable, but before you paint it, what's the
temperature on the INSIDE side of the door. The door itself may already be
adequate.

Trees, shrubs, and awnings will not cause as much palpitation by your HOA as
a reflective house.

I've got an awning over the patio - in front of the glass, sliding, patio
door. Using the $9.95 remote-sensing thermometer from HD, the concrete
directly in the sun measured 130° while the concrete on the patio measured
104°.

Gloss is reflective, if your door was gloss brown it would be maybe
5-20f cooler but white is best and will be nearest to 100f. I tried
the ceramic beads but not in your heat or sun. You could buy a pint
and do your own test, in my tests it failed. You need trees or
something to block the sun, its to bad they take forever to grow tall.

Lighter/higher gloss will help some, yes. How much depends mostly on
how big a difference you make.

I forget the site I googled for the ceramic stuff, try variations of
Insulating Paint Ceramic Beads, I painted my basement walls and a
section of the furnace duct and with an IR thermometer showed no
difference to unpainted. They have been around since at least 85, I
figure if it really worked it would be standard practice by now in
housing and industry to use the stuff. Consider awnings

I agree...stuff that works is adopted rapidly. Snake oil takes longer. ;-)
I'm not surprised your test didn't work. As I understand it, the only good
it does is on incident radiation. Claims to re-radiate the energy back
toward the source rather than conducting it to the underlying material.
That's why it sounded good to reduce solar heat gain.

I did some quick tests painting small "swatches of wood" with two different
white paints. Both were substantially cooler than my brown door.

If you've got any ceramic paint left, try painting a small board
and sticking it out in the sun.

I hit a few garage sales today and came back with several hanging shades.
They make a substantial difference where they hang...but not practical
to hang them all over the front of the house ;-)
If i could figure out how to keep them from banging around in the breeze,
I'd be a happy camper.

Interesting.
If this stuff is as great as it sounds, it's the simplest thing one could
do to save energy. The tree-huggers oughta be all over this.
Oughta be able to buy it in any home-improvement store.
California would have made it a requirement in building codes.
The fiberglass insulation people oughta be outa business by now.

But I can't find it anywhere. Paint stores ain't ever heard of the stuff.
I can't find out what it costs. Best I can find on the web is
a questionnaire that doesn't even promise a price quote.

The videos are cleverly constructed for "wow" factor, but not sure
how they relate to actual reduction in solar heat gain. Blowtorches
on unspecified metal with THICK applications of supertherm seem
unrelated to what I need.

Got any data on performance vs color? How much can I tint it from
blinding white...to keep the neighbors off my case...
when I paint the front of my house with it?

Any representatives in Portland, Oregon? I'd like to drive-by
and see what it looks like. And get some actual data in exterior
wall applications. Most of the info I find is about roof coatings.
Where can I buy small quantities?

It isnt great and the reason it isnt "everywhere" is it isnt great. I
know folks at Sherwin Williams corporate, they did tests to market it
under their own brand 10 years ago, and they still passed. Im sure its
been tested to death and it would be mandatory code if it worked

Reflective paint?
 

Slightly amusing story ..... re reflective paint.

A USAF base in another country had a supply of reflective paint which
was used in a limited manner for runway markers etc. to make them more
visible at night and in fog etc.

Since the paint was very expensive it was specially stored in locked
storage and to be obtained needed a special requisition for use by US
personnel.

One night an USAF officer was driving privately along a local
peninsula, and, so the story goes, his headlights picked up the
outline of rural shed/barn near the coastline.

The paint trim on it lit up in the headlights like nothing ever seen
before!

An investigation followed, finding that someone had had unauthorized
access to the reflective paint; some had 'disappeared' and locally had
been found useful to paint the trim on the fisherman's barn.

After all "Paint is paint isn't it?' especially if 'free' off the US
base?. Very revealing anyway!
