Wynndale The open cell spray foam insulation contains a density of 0.5lb. per cubic foot. The greater the density of the foam the heavier, or stronger it will become. This particular type of polyurethane foam is referred to as “Open Cell” because of the nature of the chemical reaction during the installation process. When the polyurethane foam is being applied the tiny cells of the foam are broken causing air to fill the “open” space inside the material, resulting in a soft or spongy material. The open cell foam carries an R-Value of 5 to 5.5 per inch (R-Value is the measure of thermal resistance, which can be found by identifying the ratio of the temperature difference across a spray foam insulator and the heat flux). 0.5lb. foam products use significantly less material than 2lb. foam products do when completing the same sized job, making them attractive to an individual concerned with conserving the foam material. Due to the fact that open cell foam requires less material, the cost of the project is much cheaper than it would be if you were to apply closed cell foam.
How to Remove Spray Foam InsulationDo you have a sneaking suspicion that the fiberglass insulation in your home or office is falling apart and not doing its job? Do you find bits of pink fluff everywhere? It might be time to ditch your tired old fiberglass insulation and replace it with something that will last. Spray foam is not only more resilient than other kinds of barriers, but it comes with numerous other benefits as well. If you're concerned about the condition of your home or building due to poor insulation, then spray foam can help solve your problems. Spray foam insulation is liquid polyurethane that dries into a tough foam consistency over a surface. Because it's liquid, it can fill in tiny cracks and holes that fiberglass can't protect. The thick, tightly sealed layer it creates is far more energy efficient than any other kind of material. It controls the indoor climate by keeping in more heat and cool air, depending on the weather. This will save you tons of money on electric bills, and be more comfortable for the occupants. Polyurethane insulation also doesn't come with any health risks. Fiberglass is made up of wiry, pink fibers that can make the skin sore and itchy if exposed to it. These fibers come loose and can be inhaled. Breathing in the fibers can cause lesions inside of the mouth and esophagus. Spray foam doesn't have tiny particles that break off and float into the air. It's also harmless to the touch, but is so durable that it does not crumble off anyways. Another benefit of spray polyurethane is that it can make your house or building more hygienic. The thick barrier prevents insects and other pests from sneaking inside. If you've had pest control problems in the past, spray foam insulation can be your new exterminator. Not even moisture stands a chance against its tough exterior. Spray foam keeps water out, which means it also keeps away dangerous mold, which can cost a fortune to repair. If you've been trying everything to get rid of mold, this material is excellent to use in existing homes. Since it can be a messy procedure, and previous insulation will have to be stripped and removed, it is recommended that only professional perform the service. You may be put off by the initial cost of having your home outfitted with a spray foam insulation kit. However, the money and time you will save in the future more than pays for itself. It will even add more value to the home or building, and you won't have to worry about replacing it. The best part about polyurethane is that it is environmentally friendly. If you're trying to make your house or building greener, then spray foam is the way to go. It is made from recyclable and renewable materials, and you'll be saving energy. Its versatility allows it to be sprayed almost anywhere, so you can even insulate the floors and ceilings. Spray foam insulation is a great move to make when you're improving your home or building.
How to Remove Expanding Foam Residue With a SolventIs polyurethane foam, in its sprayed form and as an insulator, actually environmentally friendly? What does 'green' and 'environmentally friendly' mean? All excellent questions, and all of them are not answerable in a word or two. Let's begin with defining the concept of environmentally friendly. According to the International Organization for Standardization (IOS) the term is too vague to be meaningful. The US Environmental Protection Agency (USEPA) agrees, but only to a point. The USEPA created the international Energy Star program in an attempt to provide the manufacturers of goods with a voluntary labeling system for promoting energy efficient products. In the 1990's when the program was started, it was only applied to appliances and electronics. However, today entire homes and home offices are able to gain Energy Star certification. The only criteria is the building must use 15% less energy than a standard home built to the 2004 International Residential Code. How does a home achieve that rating? The things at the top of the list for getting an Energy Star rating are not surprising: insulation, high performance windows, tight construction and ducting, energy efficient cooling and heating systems and Energy Star certified products (appliances, lighting, water heaters). Now, in reference to insulation specifically, its efficiency is measured according to R-value. An R-value is a mathematical calculation which produces the level of thermal 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. Blown in fiberglass insulation has a typical R-value between 2 and 4 per square inch. According to the US Department of Energy, the same home insulated with spray foam polyurethane insulation will have an R-value between 7 and 8 per square inch. Clearly a home insulated with spray foam would be well on its way to achieving an Energy Star rating, even without installing LED lighting and thermal windows. When a building is insulated with polyurethane foam, the costs of heating and cooling will undoubtedly be vastly reduced. Many spray foam manufacturers report that energy costs can be reduced by up to 40%; 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 fossil fuels, resulting in a smaller carbon footprint being left on our planet. We are half way to answering our title question, is spray foam insulation really green? Now we know its immense potential for energy savings, but what about the manufacture of the foam itself? In the case of spray foam, the two substances that come together to produce the foam must remain separate until the time of application. Those two things are polyol (a naturally occurring alcohol) and diisocyanate (a group of organic compounds derived from plant and animal materials). When they are brought together with water, an exothermic reaction takes place producing the polyurethane foam. Although the foam is produced from organic substances, it does not breakdown over time - a good thing for insulation applications, but where does it go when it is no longer needed? When the intended use of the polyurethane foam has been completed, it can be re-purposed and recycled. For example, the Polyurethane Foam Association has pioneered a program in the US in which spray foam insulation and products meant for the landfill are collected and made into carpet foam underlay. The program is so successful that 80% of all carpet underlay used in the US is made from recycled polyurethane foam. The reduction in waste going to landfills is incredible! So, is spray foam insulation really 'green'? Yes, it is. Polyurethane foam is produced in an environmentally friendly way in that it is created from organic compounds using very little energy or water, prevents the excess use of fuel in heating and cooling homes and is entirely recyclable for other uses.
How to Make a Spray Foam TreeSo, you have chosen to kick out the pink stuff and insulate your home using polyurethane foam insulation instead. Congratulations! You're on your way to reaping the benefits of more energy savings, less mold, fewer air leaks, greener materials, and twice the protective capability when compared to traditional fiberglass and cellulose insulation. But you won't see these advantages if you do not apply spray foam insulation properly - and that begins before you start spraying. Before you even think about moving forward, you should be thinking about safety. Protective safety goggles, full-cover clothing, a mask, and work gloves are a must for anyone applying expanding foam insulation. Make absolutely sure that no skin is exposed during application, because the adhesiveness of spray foam is similar to that of permanent glue: it will stick to skin and will not come off. If this occurs, the insulation will remain on your skin until your outer epidermal layer peels off. For the record, the only substances known to remove expanding foam are white spirit-based solvents - and only then if the insulation has not begun to set. Applying polyurethane foam insulation also opens the possibility of the material getting into your lungs, which can cause respiratory problems. In short, get confident in your ability to apply spray foam properly. Once you are ready to proceed, make sure the area where the spray foam is to be applied is between 65 and 80 degrees Fahrenheit. If it is not, either wait for the temperatures to decrease or warm the area using a bullet heater. Also, make sure the application area is clear of debris and dust in order to maximize adhesion. If there are holes or cracks in the walls or ceiling areas where you are spraying, make sure that you apply a sealant to insure a suitable air seal. Once the area to be sprayed is ready, you must turn your attention to the areas that will not be sprayed. Windows, doors, floors, drywall, and other areas must be masked with cloth or plastic sheeting so they won't be affected by over spraying. If there are any objects or structures that cannot be removed before spraying (such as air conditioners, plumbing piping, or heating units), then make sure they are completely covered as well. Again, one gap in your protective sheeting could result in a spot or stain which you may be unable to remove.
