If what you are looking for is a fiberglass roof coating for your recreational vehicle, then the Dicor RPFRC1, which is available in a 1-gallon container is an ideal option. It makes use of a hundred percent acrylic fiberglass resins formula, which is effective in providing a more flexible coating, which tends to contract and expand with each roof movement. http://m.youtube.com/watch?feature=player_embedded&v=ggLAUsiuI_o
I recently did a remodel project for my basement using spray foam insulation. The original builder has used fiberglass, but I wanted the best insulation i could find. We chose closed cell foam because it blocks moisture from getting into the house. It took one day to install and was fumey for about 3 hours. It was pretty cool watching it being done. It comes out as a liquid and then expands rapidly into a foam. It's quick! Then they took a types of saw to shave it flat with the wall studs so we could then go ahead and drywall. https://youtube.com/watch?v=ggLAUsiuI_o

Spray foam is available in two different types: open-cell spray foam which is usually $0.44 to $0.65 per board foot and closed-cell spray foam which is about $1 to $1.50 per board foot. The average cost to have spray foam professionally installed is about $2,314. This number can vary depending on whether the home being insulated is newly constructed. However, finished homes are not a good candidate for spray foam insulation but great for weatherization or an energy audit.

Closed-cell spray insulation, a rigid medium-density material, can be used in exterior applications such as continuous insulation applications, as well as interior applications. This type of foam insulation has a higher R-value per inch making it also suitable for small areas that require the highest possible R-value to meet building code requirements. Closed-cell spray foam’s rigidity help reject bulk water making it a recognized flood-resistant material by FEMA.

I have been looking to have closed cell insulation added through out my attic space. I cant seam to find a installed that wants to install no more than 2 inches, and thats not near my R-valve for South Carolina (Lake Greenwood)please send any advice that will help me to see what installer will perform the correct job.

Some states, municipalities and utilities have programs. Check with your coatings manufacturer for further information. As a membership benefit, RCMA provides maintains a database of current information on rebates and tax credits for installing reflective roofs. RCMA’s customized search tool can be used to find the most up-to-date listings of reflective roofing financial incentives available.
25 years of field study and thousands of satisfied customers have made Liquid EPDM Rubber the roof repair solution for many applications. Liquid EPDM Rubber is so versatile that it can easily be applied to metal, rubber, fiberglass, concrete, wood, fabric, foam and many other surfaces. Liquid EPDM Rubber Coating has proven to outlast acrylic, urethane and elastomerics by 4 times. There may be lower-cost products on the market but none that have the long-term durability, waterproofing ability and tolerance to extreme temperatures like Liquid EPDM. Other roofing coatings require two and three coats so not only does this triple your material cost but also triples your labor time. If you are looking to add less weight to your roof with a one coat system that has proven itself over the years look no further. Here is a sample of some of the companies during that time who have come back time and time again!
The RV roof coating is a sealing, weatherproofing and waterproofing product that is used in recreational vehicles, campers and trailers, to name some. It works effectively in sealing the roof’s membrane from water and moisture that would otherwise build up and cause damage to the roof. When unattended, the buildup can eventually leads to leaks inside the RV, causing so much discomfort to your loved ones.
Sporadic cases of hypersensitivity pneumonitis (HP) have also been reported in workers exposed to isocyanates. The symptoms may seem like the flu, with fever, muscle aches, and headaches. Other symptoms may include a dry cough, chest tightness, and difficult breathing. Individuals with chronic HP often experience progressively more difficult breathing, fatigue, and weight loss. Individuals with acute HP typically develop symptoms 4–6 hours after exposure.[4]
What do you mean by "our AC units require fresh air ventilation"? Fresh air doesn't come from the attic. If there's an atmospheric combustion appliance in the attic, such as an 80 AFUE furnace, then you shouldn't be encapsulating the attic anyway. If that's the case, you don't want spray foam on the roofline at all. You can either change out the furnace to a sealed combustion unit or do your insulating and air-sealing at the flat-ceiling level.
Thank you, Allison. We have a split system unit (actually 5) with the heat being propane. The foam guy said that it needed ventilation, so completely sealing the attic wouldn't be a good idea. It sounds like you are saying that the systems need to be vented out of the attic or replaced with some type of closed system. But I shouldn't bother spraying if the plan is to leave the soffet vents open. Is that correct?
JM Corbond® Open-Cell Appendix X Spray Foam is a lower-density, nonstructural foam that offers most of the thermal performance and installation benefits of closed-cell spray foam at a lower cost. It provides an exceptional air and sound barrier as well as R-value, and meets AC 377 NFPA 286 Appendix X requirements for application without an ignition barrier in attics and crawl spaces.

Polyurethane is a closed-cell foam insulation material that initially contains a low-conductivity gas in its cells.[5] As a result of the high thermal resistance of the gas, spray polyurethane insulation typically has an initial R-value around R-3.4 to R-6.7 per inch.[5] In comparison, blown fiberglass typically has an R-Value of only R-3 to R-4 per inch.[6]

The roof must be thoroughly cleaned, and allowed to dry thoroughly. This is a critical step to ensure a successful coating application. Be careful not to damage the lap seams. Care should be taken when pressure washing not to disturb the integrity of the underlying roof membrane particularly where there are adhered seams. Refer to the specific coating manufacturer you are using for their specific requirements for roof preparation.
