The concept of saving energy often connotes sacrifice. Less form and less function often follow reduced anything. Fortunately, this is not the case with polyurethane spray foam insulation. How does this eco-friendly product give you more instead of less?
The secret to spray foam success is found in its formulation and its efficiency. The foam materials, which are sprayed on from a tank of liquid, are made from recycled plastic water bottles and milk cartons. These post-consumer waste products are reformulated to create the foam substance. When used properly, spray foam will last practically indefinitely in walls, ceilings, floors, attics, and roofs. Foam insulation is also used in a wide variety of industrial applications as well including agricultural buildings, pipes, office buildings, warehouses and on oil and gas fields around the world. Its versatility is only matched by the superior job it does at eliminating heat transfer and sealing up cracks and voids.
Because of its excellent thermal properties, spray insulation yields more comfortable interior spaces than either batt or blown-in insulation can. It provides more insulating efficiency per inch, measured in R-value, than either alternative. So to get more insulation, you actually need fewer inches of foam than you would need with a fiberglass product. Another benefit of the product is that it is stable and doesn’t shift, sink, compress or lose its shape over time. You can think of it as a permanent solution for buildings, instead of a temporary one that is engineered to be replaced in ten to fifteen years. You get a more energy efficient product that produces better insulation, a win-win for both you and the environment.
The other benefits of spray insulation include its ability to go where no other insulation can go and create the same, efficient air barrier it does in easier to reach spots. It can also serve as a moisture barrier and is quite effective at keeping out insects and rodents which like to burrow their way into interior spaces. Sealing up voids in walls and attics also means that indoor air quality is improved when pollutants, mold, mildew spores and allergens are sealed and living spaces are protected.
The concept of less is more is applicable to foam insulation. Less waste but more comfort. Lower utility bills but more efficiency. It does cost a bit more in the short run, but long-term, you get more form and more function than with any other alternative you can buy.
