Henry Roof Coating
Hello all,
Just wanted to see if anyone ever used the Henry Aluminum Roof coating? It boasts of cutting roof temperature by 50%, and might look a little better than the white. It appears to be silver in color and has aluminum in the coat.

I used the Henry Tropicool coating and it made a big difference in comfort. Yes it's white but I was at the point of thinking the trailer was unusable and needed to do whatever I could to cool down the inside temp.

I would not install that product on my Airstream's roof.
One of the ingredients is bitumen (tar/asphalt). It is not paint.

I have it, in white, on my AS roof for 5 years now. Works great and helps with the heat and is a waterproofing material.

I use a reflective and leak sealer too. My concern was finding a coating that I could safely walk on.

HYTECH roof coating
Bus/RV roof coating. Tech jargon on website. Applied 3 years ago, 34' in Texas... almost doesn't need second AC... cool enough for me but not my bride.... so "Yes, Dear, 2 ACs! My pleasure!!"
Hytechsales.com is link. Go to order, find "Bus Kote"
Send email to them for great prep and apply process.
BTW, I can lay my bare forearm on the roof in the middle of Texas summer (high-noon daylight of course)

I will also recommend the Hytech coating and insulation beads. I did my roof this past summer and it was a lot of work but now it's much cooler, drier, and I won't have to mess around up top for a long time.

I have some history with HYTECH roof coating. I bought into the NASA technology line and painted a double-wide roof with it, It is very nice paint. It adhered well and was VERY bright. So for reflectiveness (I'm not sure that is a word), it gets very good marks.
The R rating thing just gnawed at me, however, so I did a simple test. I painted part of my hot water pipe as it leaves the heater, two coats. Then I checked the temperature with an IR thermometer. There was ZERO difference between the temp of the unpainted section of pipe and the painted section.
This means that the paint has NO insulating value.
Don't get me wrong, it is nice paint, with great reflectivity, but don't expect ANY insulation from the magic ceramic balls!

I have thought about using the Henry's Tropicool and have heard good things about it. Only thing I worry about it is future repairs. It is silicone based. They claim it will stand up to standing water without breaking down like the latex based stuff that they also make. Supposedly the Tropicool has a lifetime warranty. Any white pain that stays white and does not mildew is going to help. On the east coast mildew is a big problem. I have awning cpvers that pool water and the extra protection of the silicone coating might be worth it. I don't have any roof leaks now and with this stuff I probably won't have leaks till it is the next owner's problem. You can get the stuff on Amazon and the reviews are good. There are some bus campers that have used the stuff.

The R-value is a measure of resistance to heat flow. With no load to absorb the heat being transferred you are not measuring R. A true test (I suspect, but don't know, that it will give a different result) would be to immerse a loop of painted pipe in a volume of water and an identical loop of unpainted pipe in an identical but separate volume of water and measure the time it takes to raise the water temperature some number of degrees.
As an alternative, touch the two sections of pipe. I imagine they will initially feel the same temperature but your hand will absorb less heat (and not feel as warm after a few seconds) on the painted section as the on the unpainted one.
The test you ran is the electrical equivalent of measuring the voltage of a battery directly and through a resistor. As long as the voltmeter doesn't affect the readings you will get the same number in both cases. Put a load resistor on for one of the tests and the two measurements will be different.
But it has been a long time since I studied thermodynamics.....

None of these coatings are going to have much R-value unless it it thick like the stuff they coat truck beds with. The benefit is having high reflectance and high emitance. Aluminum has high reflectance but also low emittance so what heat it absorbs it has a hard time letting go of. Most white paints are have ceramic pigments and some sort of organic binder. NASA did research to understand this relationship and what paints run the coolest in sunlight but really any white coating is most likely taking advantage so be careful about words like NASA, and ceramic because anyone can claim NASA technology and ceramic components. It is a word game. The big thing is what is it going to look like 1-5-10 yrs down the road.

Hi Al,
Yep, I touched the pipe where the paint was and where it was not. No noticeable difference.

How much of the Bus Coat was needed for your 34?

I,also used Bus Kote on my 25er. I used 1 1/2 gal 2 coats. Removed all but AC. It has been 2 years and what a difference. cooler and quieter and NO leaks. I covered 2 inches beyond the roof rivets (white area).

The shipping on the Bus Kote stuff is a bummer...doubles the price! Wish they had a distributor in my area (Central Oregon).
By the way do Bus Kote people prime or do anything (beyond cleaning) for prep?
