To say spray foam insulation has become popular in green building over the past decade is like saying Peyton Manning is a good quarterback. It's an understatement. Although it's certainly not used in every green building project, it's become one of the most popular ways to build an air-tight house. In the early days, building codes hadn't caught up with how best to use this material, but that's changing. Change begets confusion, though, and the requirements for thermal and ignition barriers are one area where there's a lot of that.
While building codes may not require it or enforce it, spray foam should have some form of fire protection. Unprotected spray foam insulation can be a fire hazard. If spray foam is exposed to fire, it can result in a flash fire. Because of this, steps should be taken to protect against fires. Builders who do not use ignition barriers are taking on liability should a house they worked on ever burn down.

We have a 1950's ranch in Atlanta and are interviewing foam contractors to spray open cell under the roof, with an "ankle wall" out towards the eaves to seal the attic. My wife and daughters are chemically sensitive, so I'm trying to figure out how to minimize the fumes coming into the house. Additionally, at least one contractor has offered (for > $900) to remove our existing rock wool & R-13 fibreglass from the attic floor to "increase cross-ventilation into the attic". Seems to me I can't both minimize fumes AND increase cross-ventilation. They also offered to spray a fire-retardant on for >$600. Would ventilation during installation help any or woud the retardant seal off the foam and help that way? Thanks...
I employed a company to insulate my three story house in 2011. They started Insulating it in August of 2011...They said it would be a 3-4 day job. They installed it in 0.5"-8" lifts all in the same cavity, this left burned insulation and voids. They removed what they told me was the bad insulation and in the process cut many electrical wires. They fixed this. They then reinstalled too thick again in some spots and removed again. They then installed it for a 3rd time. The areas that I thought were good are now separating from the structural members leaving voids. As of October 2012, 1 year and 2 months of dealing with the contractor I told them I want proof that what has been installed carries a warranty or I want my money back and I will fix the problems myself. They have yet to provide me with this warranty. I have spent many hours in the house looking at what is bad and they need to fix. I am frustrated, 14 months of additional rent due to their negligence. I would like to know how I can get proof that the product carries the manufacturers lifetime warranty, or has it been installed improperly throughout the entire house. Desperately awaiting your response.  Spray Coating Services
This product creates a reflective silver finish, thus to help protect roof surfaces and lower roof surface temperature. It uses a low solvent formula, so it dries faster than other roof coatings.This roof coating can be applied by brush, roller or sprayer tip size .040-.061, 1000-1500 psi. We remind you that this product is not suitable for roof repairing, because it can not seal properly. Spray Coating Services

The criterion for whether your crawl space or attic is occupied is often the size of the entrance. Entry to the crawl space or attic should be a small hatch or door, not a normal-sized door. Additionally, if you cannot get to whatever area you are insulating without cutting through a drywall layer, then you do not need to use an ignition barrier, because the drywall already serves the purpose of the thermal barrier.

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.

Building code regulations typically call for the use of thermal barriers when spray polyurethane foam is installed. The code requires that the foam is separated from any living spaces by a layer of 1/2-inch drywall. As discussed earlier, any material that has been approved as being as equally fire resistant as the gypsum drywall can be substituted as a thermal barrier.
Thermal spraying need not be a dangerous process, if the equipment is treated with care, and correct spraying practices are followed. As with any industrial process, there are a number of hazards, of which the operator should be aware, and against which specific precautions should be taken. Ideally, equipment should be operated automatically, in enclosures specially designed to extract fumes, reduce noise levels, and prevent direct viewing of the spraying head. Such techniques will also produce coatings that are more consistent. There are occasions when the type of components being treated, or their low production levels, requires manual equipment operation. Under these conditions, a number of hazards, peculiar to thermal spraying, are experienced, in addition to those commonly encountered in production or processing industries.[6]
Allison--would be very interested in your take on the GHG issues of foams, which have received lots of smart commentary recently. To highlight a few: architect Jesse Thompson's comments on Tom's Good vs Bad post on Energy Circle, the very thorough piece by Alex Wilson on Green Building Advisor and Michael Anschel's cautionary diatribe on Remodeling. 
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. Spray Coating Services
The problem was that the installer was doing his first spray foam job ever, and the thickness of the insulation varied from zero (visible roof deck) to about 9". Unfortunately, good average thickness doesn't cut it. The coverage needs to be uniform because a lot of heat will go through the under-insulated areas. (See my article on flat or lumpy insulation performance.) Spray Coating
Building code uses two different terms to describe barriers that protect insulation and prevent them from catching fire. The first is called a thermal barrier, which is a poorly chosen word. Typically, scientists and builders refer to insulation as a thermal barrier. Most people would think of a thermal barrier as something that keeps heat in. However, in building code, thermal barrier essentially refers to 1/2-inch drywall, though the definition can get more complicated than that.
Yes, you're right that all of the problems mentioned above are related to the installer. I didn't try to hide that and even used the word 'installer' in two of the four headings. I can see how you'd think that the title is misleading, but in the end you can't separate spray foam insulation from its installation. Some people have the mistaken impression that if you get spray foam in your house, your home will outperform all others. My point here is that that's not true. Insulation Spray Coating
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

Manufacturers who mass-produce wood products use automated spray systems, allowing them to paint materials at a very high rate with a minimum of personnel. Automated spray systems usually incorporate a paint-saving system which recovers paint not applied to the products. Commonly, linear spray systems are for products which are lying flat on a conveyor belt and then fed into a linear spray system, where automated spray guns are stationed above. When the material is directly below the guns, the guns begin to paint the material. Materials consist of lineal parts usually less than 12 inches (30 cm) wide, such as window frames, wood moulding, baseboard, casing, trim stock, and any other material that is simple in design. These machines are commonly used to apply stain, sealer, and lacquer. They can apply water- or solvent-based coatings. In recent years ultraviolet-cured coatings have become commonplace in profile finishing, and there are machines particularly suited to this type of coating.
Vacuum plasma spraying (VPS) is a technology for etching and surface modification to create porous layers with high reproducibility and for cleaning and surface engineering of plastics, rubbers and natural fibers as well as for replacing CFCs for cleaning metal components. This surface engineering can improve properties such as frictional behavior, heat resistance, surface electrical conductivity, lubricity, cohesive strength of films, or dielectric constant, or it can make materials hydrophilic or hydrophobic.
