Freedom Foam
Freedom Foam is the most technologically advanced, patented, closed cell spray foam insulation available today. The fluorocarbon blowing agent, HFC-245fa (pentafluoropropane) typically used in manufacturing closed cell foam has been replaced by water. It is safer, more environmentally friendly, and more user friendly. It is a fully tested, class 1 building material. It was designed to conform with all state and national building codes.
Why water??
Water is obviously more environmentally friendly than any HCFC. What else makes Freedom Foam different?
Chemistry
Polyurethane foam is manufactured on site by trained contractors with specialized equipment. It is a combination of two chemicals, part A and part B. Part A is polymeric MDI. Part B is a complex blend of polyols, surfactants, catalysts, fire retardants and a blowing agent.
Typical closed cell foams use HCFC-245fa (pentafluoropropane) as the blowing agent. It was developed as a replacement for HCFC-141b. It has a low boiling point of 59.5 °F and has a low GWP (global warming potential), not no GWP, but low. It is classified as a solvent, yet is not considered a VOC (volatile organic compound in the US. Spray foams are sprayed out at about 130°F on average. With 245 foams, the blowing agent is boiling as the foam comes out of the gun. This makes the foam "foam up". The speed of the reaction is controlled by the catalysts, the size of the bubbles are controlled by the surfactants, and the density of the foam is determined by the amount of blowing agent used.
With Freedom Foam, an extra fraction of a second is needed for the water to react with the MDI, aided by the catalyst to react. The reaction relies more on chemistry than a solvent to evaporate while it is sprayed.
Contractor Friendly
Freedom Foam is much more user friendly than a 245 foam.
Because 245 boils at 59.5 degrees, constant attention has to be given to assure that the B chemical is in an air conditioned environment. Imagine trying to open an 80°F drum of chemical that is boiling inside. When this happens, care has to be given to release the pressure, and blowing agent, inside the drum resulting in lower yield. With Freedom Foam, heat is not a problem. The B component is as stable at 100°F as it is at 50°F.
Because the foam isn't starting to foam in the mixing chamber, the gun clogs less with Freedom Foam.
Roofing contractors have more control over the reaction speed with Freedom Foam. By turning the application temperature down a little and slowing the reaction, a smoother skin can be achieved, requiring less coating.
Smaller application equipment can be used. You can pre-heat the drums of Freedom Foam making it easier for smaller, more economical proportioners, with less heating capabilities to be used.
Constant R-value
With 245 foams, some of the blowing agent is trapped in the closed cells resulting in a higher initial R-value. When the foam is sprayed, it is hot. As it cools, a vacuum is created inside of the closed cells. Over time, air is drawn into the cells with the blowing agent lowering the R-value. As 245fa has only been in use for a few years, it is unknown how much 245 remains in the foam long term.
Freedom Foam has an R-value of 6 that remains constant for the life of your building. During the reaction, the gases trapped in the cells are mostly the same gases that are in the air we breathe. There is no loss of blowing agent as there is no blowing agent to lose! Plus, Freedom Foam?s proven performance has been trusted in homes since 1992!
By using Green Planet Spray Foam, you are doing your part for future generations. You are investing in your home, your health and the earth....for our children and our childrens children. Not only will it help slow the effects of global warming, but it would also help the US economy. That 40% to 50% of your heating and cooling cost that normally would be spent suporting fossil fuels over seas will stay in America supporting your local economy. Can you imagine the impact it would have if every home in your neighborhood, your town, or the state had an extra 40% to 50% of their heating and cooling cost to spend or save? Lets not forget what it would do toward reducing our footprint on the earth.
