Fred; Check out this www.mascoat.com for this ceramic insulation coating for a primer coating. I'm thinking about this product for my new skin primer. And I want to thank you for the tips on using the heater to expand the aluminum. I installed it at 160 degrees and when cooled to 103 degrees this week in South Texas it looks like a mirror. This coating would stop radiation, conduction, convection and condensation and keep the heat from getting to the metal and expanding it. When you get time check it out and let us know what do ya think? Steve | ||

Interesting that the site takes FOUR pages of double talk about R-value and still does not give a straight answer. Run the numbers - it would cost approximately $3,600 to coat just the inside ceiling area of a forty foot coach. No thanks believe I will stick with spray on foam. | ||

The ceramic coating will stop heat transfer up to 500 degrees from reaching the exterior skin. The reason being radiational heat causes conduction heating(the spread of radiational heat from skin to the frame to the screws to the inside) then convection heating(heat or cold moving through air or water) and that causes condensation. The coating is applied to the new aluminum exterior and is a base coat like primer for new aluminum or other materials. The R value is R-E not just R- and that is R-Value Equivalent. I have tested this product and I will be using it for the primer on my new aluminum skin. There are NO waves in my skin.And there will never be because the skin was put on at 160 degrees and exterior coated with ceramic coating. Now the skin will never get above the temperature inside the coach and expanding of the skin from out side heat will never reach the skin stopping radiation heating to conduction heating,to convectional heating and condensation. Also it will lower sound transfer by 12 decibels. This product has been around and is used on larger projects than just the top of school buses here in the south where the temperature can reach 120. Please understand that new and better products are produced every day. | ||

Didn't realize the 12 decibel claim, even if it is expensive that may be very acceptable expenditure for the generator bay and possibly even the engine room (provided it can be seal against the effects of hydrocarbon corrosion)especially when combined with the RE value claims. I once found a product like this that used a adherent (paint) that would allow it to be used on the exhaust pipes too. Just haven't been able to relocate that application of these mini thermos spears. | ||

ON boats the coating is used as sound deadiner , never as "insulation". FAST FRED | ||

I know I've seen ceramic coated headers for sports/race cars. They're suppose to keep the engine compartment cooler. I had a set once, but the flanges warped and leaked. I can't say positively that they did much of anything for temperature. The space shuttle uses ceramic tiles for it's heat shields, so you know they're good for a few degrees, if they're thick enough.  | ||

different application/effect for the most part, while the re-entry ceramics are very slow at thermal conduction one of the main shielding/shedding effects is the oblation (or out-gassing that occurs at that ultra high rate of friction in the ionosphere & thermosphere)from what I remember on MIRV techs back in the early 70's studies I read. | ||

TH, the shuttle tiles are nonablative, they work entirely as insulators. |
