What is SPF?
Spray Polyurethane Foam is composed of two materials, polyurethane and isocyanate. The two stay separate until they leave the gun and instantly expand and harden on the desired surface. The foam expands over 100 times its size, filling in every nook and cranny.
When can you use SPF?
Spray foam can be applied on new construction but also on an existing building. It is highly recommended that insulation is installed after electrical and plumbing has been put in.
Where can you use Spray Foam?
SPF can be applied on any dry surface (cardboard, metal, wood, piping, plastic, concrete, tank, existing insulation)
It can be applied to a new and existing attic, roof, basement, crawlspace, wall, and storage compartments.
Does Spray Foam Smell Bad?
No. SPF is hard to the touch within seconds and fully cured within minutes. It leaves behind no chemical odors or vapors. Poor quality solutions and inexperience can lead to fishy or chemical odors but Ecologic only uses the highest quality foam from very reputable sources.
How much does Spray Foam cost?
2 lb Closed Cell Foam starts at $1.25 an inch and goes up a dollar per inch. This particular foam has the highest R-value at 7 per inch (14 at 2 inches and so on.)
1.2 lb Foam starts at $0.90 an inch and goes up $0.75 an inch. This foam has an R-value of 5.4 per inch (10.8 at 2 inches.)
0.5 lb Open Cell Foam starts at $0.55 an inch and goes up $0.50 per inch. This foam has an R-value of 3.9 per inch (7.8 at 2 inches.)
What's the difference between open cell and closed cell foam?
Both foams provide excellent insulation and air sealing. They are made with almost identical chemical reactions, but there are some different physical properties. Closed cell is much more dense that open cell. Open cell renders soft flexible foam with a density of .5-.8 pounds per cubic foot. Unlike fiberglass and cellulose, ocSPF is impermeable to air at a certain thickness.
Closed cell has a cell structure that yields a rigid, hard foam and has been demonstrated to provide structural enhancement in framed building. This foam is the only spray foam that is water resistant and can be used where contact with water is likely.
Benefits of SPF
Fills all seams and gaps and stops all air leaks. This keeps cold air out during the winter and the heat out during the summer.
Prevents condensation in metal buildings which can lead to mold growth as well as damaging the contents of the building. a flash coat of 3/4 to 1 inch can prevent this.
Blocks rodents and other pests. You don't have to worry about pests burrowing in a making nests.
Stays in place. Other forms of insulation such as fiberglass or cellulose settle and sag over time creating “cold spots” because of lack of coverage. SPF adheres and never settles.
Sound proofing. Open and closed cell SPF are both great at reducing sound.
Great investment in the value of you home.
Reduces utility bills by around 40%. With all air leak filled and at least 2 inches of solid insulation you will see lower utility bills all year round.
SPF also can add structural strength to buildings. NAHB Research demonstrated SPF filled walls could add from 75% to 200% racking strength to walls of OSB, plywood, light gauge metal, vinyl siding or gypsum board.
Higher R-value. The R-Value measurement of insulation refers to the level at which the insulation prevents heat transfer. SPF has the highest R-value of any other form of insulation.
Spray foam can even be used as a form of roofing. Great for flat and pitched roofs, the foam is applied and coated with layers of roof paint the protect the foam from the elements. Ecologic's SPF roofs are guaranteed to last 15 years. Imagine how hot a dark colored roof gets during the summer. Use SPF to cover a black or metal roof with inches of closed cell foam and white paint and keep that heat out of your home.
Attics and Basements
Most homeowners don't know how poorly their attics, crawlspaces, and basements are insulated. Over and over we have seen bare box sills, attic slats, and soffits. So much air is leaking in and out along with pesky insects and rodents. Seal your home and watch your utility bills drop immediately.
Enclosed or open, SPF can easily be applied to a new or existing livestock building. By applying SPF on an open sided covered building, condensation won't disturb the livestock and temperatures can drop by 10 degrees during the hot summers. Insulate an enclosed cattle, swine, and poultry building and heating and cooling becomes much more efficient.
Happier animals produce higher yields.
Tanks, Ductwork, and Pipes
SPF can be applied directly on metal or plastic tanks, ducts, and pipes for protection and insulation. It helps maintain temperature and humidity, protects from bruising, and seals against weather. Whatever the industry and whatever your storing, SPF will enhance the strength and efficiency of your tank, duct, and pipes.
