Is usually polyurethane foam, in the sprayed form and as an insulator, actually ecologically friendly? What does ‘green’ and ‘environmentally friendly’ imply? All excellent questions, and all of options not answerable in an expression or maybe more. Discussing commence with defining the concept of environmentally friendly.

According to the Essential Organization for Standardization (IOS) the term is too vague to be significant. The US Epa (USEPA) agrees, but just to a point. The USEPA emerged up with the international Energy Star put in an attempt to provide the manufacturers of goods with a voluntary labels system for promoting energy efficient products.
In the 1990’s when the program was started, it was only placed on appliances and electronics. Nevertheless , today overall homes and home office buildings are able to gain Energy Star certification. The sole standards is the building must use 15% less energy compared to a standard home built to the 2005 International Residential Code. Just how does a home make that happen rating? The things at the top of the list so you can get an Energy Star score are generally not surprising: insulation, high performance windows, tight structure and ducting, energy effective cooling and heating systems and Energy Star authorized products (appliances, lighting, normal water heaters).
Now, in comparison with efficiency specifically, its efficiency is measured according to R-value. An R-value is a mathematical calculation which produces the level of cold weather resistance a building has. For the average North American home insulated with traditional fiberglass batts, R-value sits at between 3. 1 and 4. 3 per square inch. Offered in fiberglass insulation has a typical R-value between 2 and 4 every square inch. According to the US Department of Energy, the same home insulated with spray froth polyurethane insulation will have an R-value between several and 8 per rectangle inch. Clearly a home insulated with spray froth would be well arriving to obtaining an Strength Star rating, even without installing LED lighting and thermal windows.
When a building is insulated with polyurethane foam, the costs of heating and cooling down will undoubtedly be significantly reduced. Many spray polyurethane foam manufacturers report that energy costs can be reduced by up to forty percent; a claim that is both highly likely and easily attainable. With such a diminished use of energy, there is less demand for petroleum-based products and non-renewable fuels, producing in a smaller carbon dioxide footprint being left on the earth.
We are half way to giving an answer to our title question, is spray foam insulation really green? Now we realize their immense potential for energy savings, but what about the manufacture of the foam itself? In the case of spray froth, both substances that come together to make the polyurethane foam must remain separate until the time of app. Those two things are polyol (a naturally happening alcohol) and diisocyanate (a group of organic and natural substances derived from plant and animal materials). When they are brought along with normal water, an exothermic reaction uses place producing the reboundable foam. Although the froth is created from organic and natural chemicals, it does not malfunction over time – a good thing for efficiency applications, but where will it go when it is not needed ever again?
When the intended use of the polyurethane froth has been completed, it is usually re-purposed and recycled. To get instance, the Polyurethane Froth Association has pioneered a program in the ALL OF US through which spray foam efficiency and products meant for the landfill are accumulated and made into carpet foam underlay. This program is so successful that 80% of all carpet underlay used in the US is made from recycled polyurethane material foam. The reduction in waste going to landfills is incredible!
