OK, Peter, I finally went back and read Alex Wilson's article on what he perceives as a serious problem. I haven't seen the full report, but based on the summary he wrote on the Green Building Advisor website, I question the science. It seems to me that he's chosen the wrong metric and he's basing his conclusion on too many assumptions because he doesn't have enough data. You can see my comments at the end of his article.

The process typically operates at 39–120 °C to avoid thermal damage. It can induce non-thermally activated surface reactions, causing surface changes which cannot occur with molecular chemistries at atmospheric pressure. Plasma processing is done in a controlled environment inside a sealed chamber at a medium vacuum, around 13–65 Pa. The gas or mixture of gases is energized by an electrical field from DC to microwave frequencies, typically 1–500 W at 50 V. The treated components are usually electrically isolated. The volatile plasma by-products are evacuated from the chamber by the vacuum pump, and if necessary can be neutralized in an exhaust scrubber. Spray Coating
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. Spray Coating Services

Fiberglass is the giant in the insulation industry, and the R rating to which it conforms is ingrained in the minds of contractors, builders, and code inspectors. Insulating ceramic coatings offer an alternative to traditional batt insulation. “Fiberglass insulation is tested and rated at 73 degrees Fahrenheit, which is the ideal temperature for fiberglass,” says Pritchett. Under harsher conditions, Pritchett suggests that fiberglass doesn’t perform as well as its ratings predict.
E/M Coating Services applies other coatings that provide performance-enhancing benefits such as corrosion protection, wear resistance, electrical insulation, electromagnetic shielding and chemical agent resistance. These coatings can be powder or liquid coatings such as PTFE, Xylan®, Epoxy, Polyester or Urethane. E/M Coating Services facilities have numerous OEM approvals for the application of coatings to aerospace, automotive and other industrial components in addition to FAA, Nadcap and ISO 9001/9002 approvals that might be required at individual facilities. E/M Coating Services can assist you in selecting the right coating to meet your design challenge, lower the cost of ownership or enhance the performance and longevity of your products. Selection of the proper coating can facilitate the use of less expensive metals, improve part wear life and reduce maintenance costs.
Spray foam insulation, when properly installed is both an air barrier and when closed cell foam is used at the proper depth a vapor barrier!  Before hiring any contractor you should establish the brand of foam being used and verify that with the named manufacture.  Please ask for ESR reports and MSDS sheets on any foam being installed in your home. A couple areas where you might consider spray foam insulation include:
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.

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.
Hydraulic or air powered airless provide a more uniform pressure control since the paint piston moves at a constant speed except when it changes direction. In most direct drive piston pumps, the piston is crankshaft driven in which the piston will be constantly changing speed. The linear motors of hydraulic or compressed air drive pumps, are more efficient in converting engine power to material power, than crankshaft driven units. All types of paint can be painted by using airless method. Spray Coating Services

Estimated Coverage: Standard product coverage on a smooth surface for Ames® Super Primer™ is 200 sq. ft. per gallon per coat and the product coverage rate for Ames® Maximum Stretch® and Ames® Iron Coat® is 100 sq. ft. per gallon per coat. Rough or uneven surfaces may require additional product. More than one coat of Ames® Maximum Stretch® or Ames® Iron Coat® is recommended. More coats equal longer life. Coating Services
