This is in great contrast to my friend's experience. Her attic spaces were sprayed and the foam is actually pretty, and I was in her attic 6-7 days after it was sprayed and could hardly smell anything when I stuck my face up to the foam. And she did not have to clean up one speck of dust during or after the spraying. I got the name/number of the guy from her who managed her attic project, but between the time he did my house and the time he did her house, he was let go from the company who did her attic and hired by another company. He assured me everything would be the same, etc., etc., and I had no reason to believe anything had changed, but the sprayers who did my house later admitted they had never sprayed an attic before and I also found out that the foam used in my attic was from a different manufacturer. Neither my friend nor I had any idea this guy was with different company then, until the week after they filled my attic with off ratio foam, and my home with toxic vapors.   Spray Coating Services
Heat Shield™ EPX–H2O is our #1 high temperature industrial protective insulation coating for equipment. It is a super-powered thermal insulating coating that is also chemical and corrosion resistant and cures within 2 hours to 2 days. Our best in class thermal insulating coatings are proven to solve the most difficult energy efficiency, corrosion, CUI, moisture, and safe touch problems of factories and industry around the world.
once the foam is installed correctly, it is a inert plastic not much different than the foam cushions you sit on. there is not a health rick unless you have off ratio uncured foam that has not mixed properly. the foam is absolutely a health risk in its raw forms before it is mixed and cured. You should not be in the building without proper respirators and eye protection. The spray foam industry should be controlled and regulated by the same standards, testing and inspections that framing ,electrical and plumbing are. until that happens then you will have idiots with spray rigs ruining peoples homes and ruining the market for honest foam contractors that know how to price a job fairly and complete it correctly.

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.
“Since most of mechanical heat is IR heat, ceramic coatings can be used to prevent heat loss from inside a building,” Pritchett says. A home interior coated in ceramic paint can therefore reduce energy costs due to heat loss in the colder months. “We estimate that a home can save up to 40 to 50 percent in energy costs using our product,” Pritchett says. Payback on a product like SuperTherm, which retails for about $100 per gallon, can come in as little as two years.
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:
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.  Spray Coating Services
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.
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.
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.

The Rubberseal creates a coat that can efficiently reflect heat off the roofs of buildings. It is Energy Star rated, which means it’s friendly to the environment.The spread rate of this product is 60 square feet per gallon at 20 imperial mils. It dries in 2 hours but takes 72 hours to get fully cured. Check the weather forecast before you apply it.
Simple – we’ve seen experienced contractors work with the separate nitrogen tanks and spray foam rigs and have one heck of a time. These spray foam insulation kits are quick to learn and simple to use. They’re designed to be easy so you get results the very first time you spray. Thorough Instructions, 24/7 Product Support, and videos make it easy to install. Spray Coating Services
The video below is from a house near Charleston, South Carolina that I visited recently, and you'll see that the homeowner in this case didn't get his money's worth. I knew immediately when I walked into the attic that something was wrong because it was hot up there. In a properly insulated spray foam attic, the temperature won't be much higher than the house temperature.  Coating Services
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
