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. Insulation Spray Coating

Thorough Instructions, 24/7 Product Support, and videos make it easy to install. Spray Coating Services
There have been a few mentions of intumescent coatingsabove, and it would be helpful to elaborate on them. Intumescent coating is a type of paint that will bubble when it is exposed to heat or flames. The bubbles act as a barrier that is relatively flame resistant. The bubbled coating delays the ignition of the spray foaminsulation. Because of this, intumescent coatings have become more common in building and construction.
In plasma spraying process, the material to be deposited (feedstock) — typically as a powder, sometimes as a liquid,[2] suspension [3] or wire — is introduced into the plasma jet, emanating from a plasma torch. In the jet, where the temperature is on the order of 10,000 K, the material is melted and propelled towards a substrate. There, the molten droplets flatten, rapidly solidify and form a deposit. Commonly, the deposits remain adherent to the substrate as coatings; free-standing parts can also be produced by removing the substrate. There are a large number of technological parameters that influence the interaction of the particles with the plasma jet and the substrate and therefore the deposit properties. These parameters include feedstock type, plasma gas composition and flow rate, energy input, torch offset distance, substrate cooling, etc. Insulation Spray Coating
The problem you saw with the closed cell foam pulling away like that is due to the heat of the foam was to hot. It was actually curing out and making foam before it could adhere to the wood. The installer wasn't reading his foam correctly. He should of stopped and turned down the heat on his hose temp. Also installers have to be aware that as the sun rises and the temp in attics rises the subtrates get hotter as well. This will cause the installer to adjust his heat when installing the foam as the temp changes thru out the day.  
Thermal barriers are defined in building code as 1/2-inch gypsum wallboard or any material that is as equally fire resistant as 1/2-inch gypsum wallboard. The gypsum wallboard is known as a prescriptive thermal barrier. Materials are tested in a 15-minute fire test in order to determine whether or not they are equal in fire resistance to the 1/2-inch gypsum wallboard. If they are, then they can be used and counted as the equivalent of gypsum wallboard. Coating Services
The fluid pressure is provided by an airless pump, which allows much heavier materials to be sprayed than is possible with an airspray gun. Compressed air is introduced into the spray via an air nozzle (sometimes called air cap) similar to a standard conventional spray gun. The addition of compressed air improves the fineness of atomization. Additionally unlike a pure airless spray gun, an AA gun has some control over fan spray to round spray. Some electric airless sprayers (Wagner and Graco) are fitted with a compressor to allow the use of an air-assisted airless gun in situations where portability is important. Spray Coating Services
Chris M.: Yes, I meant to mention in the article that this applies to both open cell (a.k.a. low density or 1/2 pound SPF) and closed cell (a.k.a. medium density or 2 pound SPF). Foam board insulation also needs to meet the requirements for thermal and ignition barriers, and some products, like Dow Thermax, have gotten approval to be left exposed. 

There is a significant price difference when it comes to using foam insulation to insulate a new versus older home. Spraying insulation inside a newly constructed home is easier because the installation company can ensure the insulation will work effectively and design it for optimum defense against sound, heat transfer and utility costs. Installing spray foam in older homes that contain existing insulation can cost additional time and money -- it is not usually recommended as compared to weatherization or an energy aduit.
When using this roof coating, two coats are required. It doesn’t take much time to apply the coating. If the weather is not humid, the coating will take only a few hours to get completely dry in full sun.This coating can go over and hold strong on the sealing tapes. This feature helps you to restore your roof to brand new. It may save thousands of dollars from replacing your old roof. Coating Services

Charles spoke of a "huge problem" of convection within cavities not filled with foam. This is a false assertion. The trillions of trapped air cells in foam insulation prevent heat transfer at a rate that would cause those problems. Also the wood framing members are relatively good insulators themselves unless the wood is particularly dense. Convection currents against foam insulation are not the problem he asserts. He also said" the homeowner is literally pissing money away if he pays for this spray foam job - or any job like it - for he will only be gaining a marginal amount of insulation effectiveness." This is a ludicrous statement. The structure pictured above will have a very effective performance despite his assertions. My only concern is humidity. Closed cell foam does not permit moisture migration and trapped moisture could be a problem, especially if the AC is not running due to moderate to cold temperatures.

A rule of thumb puts two thirds of the coating on the substrate and one third in the air. True HVLP guns use 8–20 cfm (13.6–34 m3/h), and an industrial compressor with a minimum of 5 horsepower (3.7 kW) output is required. HVLP spray systems are used in the automotive, decorative, marine, architectural coating, furniture finishing, scenic painting, and cosmetic industries. Coating Services

I am building a house in Central Texas (Caldwell). Several builders are cautious about using foam insulation and/or a closed attic. I would like to use both. Here in Texas, heat and humidity (except for the past few years of drought) are a continuing problem. Which type of foam would be the best to use in our home, where should the vapor barrier be or should be use one at all, if we are using fans in the exterior walls to supply fresh air to the house, do we need a vented attic or will it cause more problems than it solve? I have printed out your article and the blogs to give to my contractors and architect, but I would really appreciate your comments on the products being used in my part of the US. 
High volume low pressure (HVLP) is similar to a conventional spray gun using a compressor to supply the air, but the spray gun itself requires a lower pressure (LP). A higher volume (HV) of air is used to aerosolise and propel the paint at lower air pressure. The result is a higher proportion of paint reaching the target surface with reduced overspray, materials consumption, and air pollution. A regulator is often required so that the air pressure from a conventional compressor can be lowered for the HVLP spray gun. Alternatively a turbine unit (commonly containing a vacuum cleaner derived motor) can be used to propel the air without the need for an air line running to the compressor. Coating Services
I've seen this only once, and it was with closed cell foam, but I've heard of it happening with open cell foam, too. I don't know the details, but I've heard it could result from a bad batch of chemicals, improper mixing, or too high a temperature. Whatever the cause, it's not a good thing. The photo below shows how the spray foam pulled away from the studs. A little bit of uninsulated area like that adds up to a lot of heat loss/gain when the whole house has that problem, as it did here. Coating Services
With the increase in spray foaminsulation, many are wondering whether or not you should use a thermal or ignition barrier. Additionally, many are wondering if building codes require ignition or thermal barriers with spray foam insulation. The short answer is that you should use a thermal or ignition barrier, but the code may not necessarily require it. Building codes are often complicated, poorly written, poorly enforced, and up to interpretation by local code officials. This results in ambiguous requirements regarding spray foam insulation and fire protection.

Spray polyurethan foam does effectly prevent all six of these heat transfer methods from occurring. These should be the mechanisms by which you judge insulation, in addition to their R-Value. If you're uncertain about installing spray foam insulation, Energy Star has a map that recommends levels of insulation by R-value and cost-effectiveness in the United States.
This is more common with closed cell foam, but it happens with open cell foam, too. Since closed cell foam has a higher R-value per inch, installers generally spray 2" in walls and 3" in rooflines to meet the energy code requirements of R-13 and R-19, respectively. (I'm not going to dive into the energy code here, but these numbers apply to many climate zones, the latter being allowed under the UA tradeoffs rule. See the Energy Nerd's blog on this topic if you want to argue.) Spray Coating Services

The standard prescriptive material that can be used as a thermal barrier is 1/2" gypsum board (a.k.a. drywall or sheetrock). Anything else has to be approved as an 'equivalent thermal barrier' by undergoing tests for temperature transmission and fire integrity. In some cases, however, you need only one test. According to the Spray Polyurethane Foam Alliance (SPFA), "Under specific conditions, the temperature transmission test can be waived if approved by building code authorities on the basis of large-scale fire testing representing actual uses." (See their pdf document, Thermal and Ignition Barriers For The SPF Industry.) Coating Services
Plasmas affect materials at an atomic level. Techniques like X-ray photoelectron spectroscopy and scanning electron microscopy are used for surface analysis to identify the processes required and to judge their effects. As a simple indication of surface energy, and hence adhesion or wettability, often a water droplet contact angle test is used. The lower the contact angle, the higher the surface energy and more hydrophilic the material is.

Electrostatic painting was first patented in the U.S. by Harold Ransburg in the late 1940s. Harold Ransburg founded Ransburg Electrostatic Equipment and discovered that electrostatic spray painting was an immediate success as manufacturers quickly perceived the substantial materials savings that could be achieved. In electrostatic spray painting or powder coating, the atomized particles are made to be electrically charged, thereby repelling each other and spreading themselves evenly as they exit the spray nozzle. The object being painted is charged oppositely or grounded. The paint is then attracted to the object giving a more even coat than wet spray painting, and also greatly increasing the percentage of paint that sticks to the object. This method also means that paint covers hard to reach areas. The whole may then be baked to properly attach the paint: the powder turns into a type of plastic. Car body panels and bike frames are two examples where electrostatic spray painting is often used.
One of the high-tech insulation products being utilized these days is a foam-spray product called "Icynene," which is a foam that starts as two liquid components (a and b, if you will) that are heated up and sent through two hoses and meet at a tip of a gun where the magic begins. This is a thin film that expands to 100 times its volume in eight seconds, when it's permanently set up. Spray Coating Services
The drawback to spray foam insulation is it's been known to cause certain health issues such irritation of the eye and the gastrointestinal and respiratory tracts. Direct contact can cause inflammation to the skin, and some individuals have been known to break out in a rash on the arms, chest and neck area. Spray foam insulation has also been linked to a few cases of hypersensitivity pneumonitis. This condition can cause: Spray Coating Services

I've used P&S BeadMaker, Meguiars Express Wax, Carnuba Wax, CMX and most recently Meguiars Hybrid Wax. To tell you the truth, if you're a gloss and slick addict, it really boils down to how well you prep your car. Wash, clay bar, compund, and polish. IPA wipe down. Anything else you put on after will highlight the shine you prepped with all the pre-work. Spray Coating Services

Prodex eliminates the moisture (condensation) from forming on the metal sheeting. It does it by making the temperature of the metal sheeting on the building approximately the same on the inside as the outside. When the heat or cold from outside comes through the metal skin it hits the outside aluminum facing of Prodex and is reflected back upwards through the underside of the metal sheeting. This process keeps the metal sheeting temperature consistent on both sides. In addition, the inside layer of aluminum in Prodex reflects away the heat (heater) or cold (air-conditioning) from inside the building, from getting to the metal skin. This also helps in preventing condensation.

By heating the full-bodied paint to 60-80 °C, it is possible to apply a thicker coat. Originally the paint was recirculated, but as this caused bodying up, the system was changed to direct heating on line. Hot spraying was also used with Airless and Electrostatic Airless to decrease bounce-back. Two pack materials usually had premix before tip systems using dual pumps. Spray Coating
