In recent years, there has been a significant rise in the use of spray foam insulation in construction. Spray foam insulation varies from traditional insulation, such as fiberglass, in many respects. Fiberglass insulation is typically much cheaper than spray foam insulation; however, it is also less effective at insulating your home. Additionally, spray foaminsulation requires professional installation. Though spray foam insulation is on the rise, fiberglass is still the most common form of home insulation used today.

Steve: If your spray foam installer leaves the vents open, he will be committing the 2nd of the 4 problems I described above. You will most likely have comfort and efficiency problems. You may well have condensation problems. You will be spending a lot of money on a product that likely won't perform as it should. Don't let him leave the vents open. If the installer you've chosen doesn't understand this, you may want to choose someone else. 
Spraying paint with compressed air can be traced back to its use on the Southern Pacific Railway in the early 1880s[1] In 1887 Joseph Binks, the maintenance supervisor at Chicago's Marshall Field's Wholesale Store developed a hand pumped cold-water paint spraying machine to apply whitewash to the subbasement walls of the store.[2][3] Francis Davis Millet, the decorations director for the World's Columbian Exposition in Chicago in 1893, used Binks and his spray painting system to apply whitewash consisting of a mix of oil and white lead to the buildings at the Exposition, taking considerably less time than traditional brush painting and tuning it into what has been called the White City.[4][1][3] In 1949, Edward Seymour developed a type of spray painting, aerosol paint, that could be delivered via a compressed aerosol in a can.

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.) Insulation Spray Coating
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

In classical (developed between 1910 and 1920) but still widely used processes such as flame spraying and wire arc spraying, the particle velocities are generally low (< 150 m/s), and raw materials must be molten to be deposited. Plasma spraying, developed in the 1970s, uses a high-temperature plasma jet generated by arc discharge with typical temperatures >15,000 K, which makes it possible to spray refractory materials such as oxides, molybdenum, etc.[1]

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.

When intumescent coatings are used with spray foaminsulation, they are specific to each insulation brand. You cannot use one intumescent coating with a brand that it was not intended for. If you do not use the properspray foaminsulation brand and intumescent coating combination, then your work will not technically be up to code. Additionally, it is important to keep in mind that intumescent coating can only be used as an ignition barrier alternative if it is being used in an attic or crawl space. And, even then, it can only be used if space is not used for storage and is accessible through a small hatch or door.
The atomization of molten materials produces a large amount of dust and fumes made up of very fine particles (ca. 80–95% of the particles by number <100 nm).[8] Proper extraction facilities are vital, not only for personal safety, but to minimize entrapment of re-frozen particles in the sprayed coatings. The use of respirators, fitted with suitable filters, is strongly recommended, where equipment cannot be isolated.[8] Certain materials offer specific known hazards:[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.  Coating Services

Kool Seal may be the best roof coating because it clings to your roof in all temperatures. It provides good protection against moisture, so it is suitable for humid areas.This product forms a thick barrier for the roof, which can reflect 90% of the sun’s rays. Whether in the hottest summer or in the coldest winter, this product maintains durable and protective.
Jennifer, I'm not an expert on the health effects of closed cell foam. A lot of people live in houses with closed cell foam and have no health problems from it, at least not short-term, acute problems. I do know of one person who had it removed from her crawl space because she was convinced it caused her dog to get sick, but I know only what she told me.  
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.
Our insulation and protective coatings are designed for the harshest outdoor and offshore environments, such as those experienced by our customer Sinopec on their offshore fuel oil storage tanks, black liquor tanks in pulp and paper mills like those of Weyerhaeuser, and even in the frigid cold of Alaska where our thermal barrier insulation coatings helped insulate steam and water pipes for the U.S. Army. Our customers choose Synavax™ industrial and building insulating coating solutions because of the superior combined energy savings, stay clean, and asset protection benefits. Spray Coating Services
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.
Mascoat is a great alternative to conventional insulation materials, including cellular glass, perlite, mineral wool, fiberglass, urethane & closed cell foam and calcium silicate. Mascoat coatings are lighter than traditional insulation, reducing bulk in your structure. Mascoat also requires much less maintenance than conventional insulation, which can ultimately save you time and money. Want to get started with Mascoat? Request more information today.

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. Spray Coating
