A contractor build two houses with 2 by 6 walls. He sprayed 1.5 inches of foam into the walls of one house and used standard fiberglass insulation for the other house.
The house with polyurethane insulation always had lower electric bills. They believe this is do to the fact that the foam is the worlds best insulation and it seals all air leaks.

Where could one find some Polyurethane Foam Insulation?
Polyurethane foam insulation is the most popular insulation on the market today. It is easily installed, it is sprayed into the walls where it coats and hardens. All home improvement stores carry it.
What is the best type of insulation?
The Best Type Of Insulation is Spray Foam Insulation. Because Spray foam insulation, also known as polyurethane foam insulation, is a superior form of insulation that provides a higher thermal insulating value (also known as R or RSI value) than conventional batt insulation. The application ensures that any gaps are sealed, providing a vapor barrier, moisture barrier, air barrier and even a radon barrier, thus stopping any thermal loss due to drafts or leaks. This makes spray foam up to 50% more energy efficient that other insulation solutions, resulting in cost savings on energy and gas bills. It is important to understand that a lot of the heat or cold air loss happens due to the air leaks on your walls or roofs, and that the cheaper batt insulation installation is quite susceptible to leaks if the vapor barrier (that layer of poly plastic applied just before the drywall) is not properly installed or if it becomes damaged. Further, unlike batt insulation, spray foam barrie insulation does not shift, sag or become wet or moldy. Rather it adds to the structural integrity of the house, with the added benefit of keeping out pests or vermin. For More Details Visit sprayfoammasters.ca
What is two-component polyurethane?
All polyurethane contains two chemicals: a diol and a diisocyanate. (There's also a catalyst called DABCO and a few other items in there to modify the finished polymer, but for now let's stick with the two important ones.) A two-component polyurethane brings you the diol and the diisocyanate as two separate packages. There are a couple of two-component systems available to someone who doesn't own a plastics plant: car paint, where you put hardener in the paint to make it dry, and sprayed foam insulation. The way most of us get our polyurethane is as single-component systems, because diisocyanate is very poisonous. Polyurethane varnish, Gorilla Glue, and polyurethane construction adhesive all work the same way: the diisocyanate is missing parts. If you add water to it--whether through the air or by moistening the surface--the diisocyanate picks up what it needs and the urethane reaction commences.
Can you spray paint polyurethane foam?
Spray polyurethane foam is a plastic spray that is installed as a liquid then expands many times its original size. It is used in a variety of uses including roofing, air barriers, and insulation of commercial and residential buildings. It is also used to insulate freezers, walk in coolers, and produce storage rooms. Polyurethane has also been used to increase the structural strength of wings in airplanes.
What kind of plastic is polyurethane plastic?
Polyurethane (PUR and PU) is a polymer composed of a chain of organic units joined by carbamate (urethane) links. While most polyurethanes are thermosetting polymers that do not melt when heated, thermoplastic polyurethanes are also available. Polyurethanes plastic commonly used in the manufacture of flexible, high-resilience foam seating; rigid foam insulation panels; microcellular foam seals and gasket - in.kompass.com/a/bottles-plastic-for-the-pharmaceutical-and-cosmetic-industry/2071009/
Is polyurethane rigid insulation popular?
no
What is the dimensions of batt insulation?
Batt insulation comes in a variety of widths, lengths and thicknesses.

What is polyurethane foam insulation?
It is polyurethane that has been expanded with air when liquid, and formed into sheets, often 2-3 inches thick.
What material is a cool box?
Usually polyethylene (casing) and polyurethane foam (insulation).
What does an R-Value tell you?
It is the measure of insulation against heat/cold afforded by varying thicknesses and composition of construction insulation materials. The higher the "R" Value the better the insulation characteristics.
What purpose is polyurethane foam used for?
Polyurethane Foam as it can be cast, carved and sculpted, finds its uses in many applications in seating, insulation, seals and gadgets, automotive bushings, wheels and tires and more. They are used in filters of air purifiers; Self adherent polyurethane foam paddings are of great surgical use as supports and dressings. Polyurethane foam is used in seating, insulation, adhesives, carpets, plastics and even on vehicles. It is mainly used for insulation purposes as well as fire protection.
Any place I can rent the machine and purchase the material to blow polyurethane insulation in a new construction home?
Probably not as insulation can be a health hazard when being installed, but check with your local home stores to be sure.
Who invented rubber balls?
You need to define the answer. Foam can be confused with bubblly foam (like in the bath, doing the dishes) and then there is Polyurethane foam, what people use as padding for insulation. For Polyurethane foam information, seek out this information from this eHow website: http://www.ehow.com/about_4673650_history-polyurethane-foam.html
Is working with polyurethane safe to work with ?
Polyurethane refers to a complex organic chemical construction based around polymers. It has numerous commercial uses from rigid foam for seats and insulation to wheels, tires and hard plastic parts for electronic instruments.
Can Polyurethane foam be used for home insulation?
Had my chem teacher in highschool grow the PU foam in front of the class, how did he do it? You need four chemicals: A polyol. For foam, glycerin will work. A diisocyanate. A catalyst called DABCO, which has a REALLY long name. And a blowing agent; for this we'll use water. There are two reactions going on here. First is the urethane reaction--DABCO bonds the polyol to the diisocyanate to form the urethane molecule. Then comes the water...when diisocyanate and water are mixed, carbon dioxide is liberated. The little CO2 bubbles are trapped in the polyurethane and make it foamy.
Which window shades provide the best insulation from the cold?
