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.
Warm spraying is a novel modification of high velocity oxy-fuel spraying, in which the temperature of combustion gas is lowered by mixing nitrogen with the combustion gas, thus bringing the process closer to the cold spraying. The resulting gas contains much water vapor, unreacted hydrocarbons and oxygen, and thus is dirtier than the cold spraying. However, the coating efficiency is higher. On the other hand, lower temperatures of warm spraying reduce melting and chemical reactions of the feed powder, as compared to HVOF. These advantages are especially important for such coating materials as Ti, plastics, and metallic glasses, which rapidly oxidize or deteriorate at high temperatures.[1]

Good article, but it seems like you can chalk up almost all of those problems to the experience level of whomever is spraying the foam. Spray foam isn't an inherently bad product, but it's pretty easy to botch if the hired company is inexperienced. Fiberglass may be foolproof to install, but then again it has a terrible R-Value compared to a good spray foam. People just need to get referrals and do their homework whenever they research a spray foam contractor.
The second type of barrier that prevents insulation from catching fire is called the ignition barrier. Ignition barriers are a lower standard to meet than a thermal barrier. Additionally, several different materials can meet the definition of an ignition barrier. Now that we have established the code jargon for spray foam barriers, we can look at each type in detail.

In the case you have above the installer wasn't reading his foam. They must be trained to do that as they spray. Temps and conditions are constantly changing thru out the day. Either he wasn't properly trained or if he was,he wasn't doing his job! This is a serious problem with people jumping in to the foam business. A lot of homeowners and builders are looking the best price and end up with someone who doesn't know what they are doing. Hope this info helps. Foam insulation is a great product. It just has to be done right by someone who knows what they are doing.
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.

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

Due to a wide range of nozzle shapes and sizes, the consistency of the paint can be varied. The shape of the workpiece and the desired paint consistency and pattern are important factors when choosing a nozzle. The three most common nozzles are the full cone, hollow cone, and flat stream.[6] There are two types of air-gun spraying processes. In a manual operation method the air-gun sprayer is held by a skilled operator, about 6 to 10 inches (15–25 cm) from the object, and moved back and forth over the surface, each stroke overlapping the previous to ensure a continuous coat.[7] In an automatic process the gun head is attached to a mounting block and delivers the stream of paint from that position. The object being painted is usually placed on rollers or a turntable to ensure overall equal coverage of all sides. Coating Services

Whether or not an intumescent coating, or even a thermal or ignition barrier, is needed often depends on the type of spray foaminsulation that builders use. Many closed cell foam sprays are already sufficiently fire resistant and need no additional barriers. Ultimately, whether or not you need an ignition barrier or thermal barrier varies depending on location and materials. You should check with your local code official to ensure that your insulation work is up to code.

Open cell spray foams are less common and have a lower resistance to heat flow than closed cell spray does. Open cell spray foaminsulation expands when it is applied, which allows it to be installed in hard to reach areas, such as small wall and ceiling cavities. Open-cell spray foam is typically cheaper than closed cell foam is, but it is more permeable and vulnerable to fire hazards. Coating Services

Sean, thanks for jumping in and answering John's questions. About choosing the right foam, I intentionally avoided the open cell vs. closed cell foam debate. I did this partly because it's worthy of an article all by itself, but mainly I didn't include it because, despite all the warnings the two sides issue about the other, I've never personally seen a problem caused by using open cell where they should've used closed cell or vice versa. I'm sure things like that happen; I just haven't seen it yet. Coating Services

This technique is mostly used to produce coatings on structural materials. Such coatings provide protection against high temperatures (for example thermal barrier coatings for exhaust heat management), corrosion, erosion, wear; they can also change the appearance, electrical or tribological properties of the surface, replace worn material, etc. When sprayed on substrates of various shapes and removed, free-standing parts in the form of plates, tubes, shells, etc. can be produced. It can also be used for powder processing (spheroidization, homogenization, modification of chemistry, etc.). In this case, the substrate for deposition is absent and the particles solidify during flight or in a controlled environment (e.g., water). This technique with variation may also be used to create porous structures, suitable for bone ingrowth, as a coating for medical implants. A polymer dispersion aerosol can be injected into the plasma discharge in order to create a grafting of this polymer on to a substrate surface.[3] This application is mainly used to modify the surface chemistry of polymers.

There are exceptions to the thermal barrier rules. If the spray foam insulation is used as roofing or covered by concrete whichis, at least, an inch thick, then thermal barriers are not necessary. Additionally, you do not have to use a thermal barrier if the spray foam insulation is used on the interior of sill plates and rim joists, so long as the spray foam is 3 1/4 inches or less. Thermal barriers are also not necessary if the spray foam insulation is used in an attic or crawl space, as long as they are not used for storage or as living areas. In attics and crawl spaces where thermal barriers are not required, the use of ignition barriers is necessary. Insulation Spray Coating
This is where things get a little tricky. If a home has spray foam insulation in an attic or crawl space, the building code requires using materials or assemblies that offer some fire resistance but not as much as is required for a thermal barrier. If you've got spray foam insulation in an attic, for example, it's probably already separated from the living space by a thermal barrier. Most ceilings are made of 1/2" drywall. But the spray foam is still exposed to the attic and needs an ignition barrier.
Water beading is impressive using CMX. Wife's car sat out all day in rain in a outdoor parking lot, she drove home and car looked almost dry! Car looks like I just washed it. Shaking CMX before application and during application, still getting small white beads. I think it's residue after spraying off and wiping off immediately. I think CMX evaporates on towel and is creating small beads that fall onto car, like compound or polish that leaves dust residual, but these are tiny white bead particles...That's the only pain I see to using this product.
A spray booth is a pressure-controlled closed environment, originally used to paint vehicles in a body shop. To ensure the ideal working conditions (temperature, air flow, and humidity), these environments are equipped with ventilation, consisting of mechanical fans driven by electric motors, and optionally burners to heat the air to speed paint drying. Toxic solvents and paint particles are exhausted outside, possibly after filtering and treatment to reduce air pollution. Prevention of fires and dust explosions is also a high priority. In order to assist in the removal of the over sprayed paint from the air and to provide efficient operation of the down-draft, water-washed paint spray booths utilize paint detackifying chemical agents.

I applied this product on a rolled asphalt flat patio roof. It was over 90 degrees and I could not touch the roofing at all on the first coat. I was laying on layers of cardboard to apply the silicone under the gutters and then rolled the first coat. The next day I brought all the cardboard to apply the coating under the gutters. I accidentally touched the roof and it was cool‼️  I threw the cardboard off the roof, laid down to do the gutters and roll the second coat. I was amazed how well this sealed and cooled the patio. I am going to apply this to my other patio and covered parking which are metal. I can’t wait to apply for sealing and adding cooling to these areas. Roof Coating Supply answered all my question and they ship promptly - I had my order in 3 days. Thank you. Spray Coating
