Greenwood 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 Fix Holes in Tree TrunksIf you're planning to purchase new spray foam insulation then it might help you to understand certain information about the product. Spray foam insulation is one of the latest options for you that are available today when we talk about home insulation. It is basically easier to use, because of this many people prefer to use the spray foam insulation and it also comes with long term savings advantage for you. When you think about your home and building it, insulation is one of the necessities that are on top most of the time. But insulation planning is not as easy as buying an appliance. You have tons of things to note about certain facts and information you have to consider which may give you a hard time; which is why being well informed about the product will offer some advantage so that you won't be making any wrong decisions. So what is spray foam insulation? It is a synthetic material that is created from a combination of organic and inorganic materials with chemicals that are combined together. A combination of an organic resin polysol and isocyonate is a type of material that is created in a specific temperature and pressure conditions to produce a polyurethane material through a chemical reaction. These organic materials have a unique way of expanding itself to create a larger size to about 100 times it original volume. Just like simple foam. This foam will become stiff and eventually harden after you apply it to all the spaces in which it is sprayed on and this will create a thermal cover. This is an effective way of creating a barrier that provides insulation to the walls of your home. This in turn will create air flow obstruction to the spray foam insulation that was applied in wall cavities, concrete gaps, sheathing interior and dry walls. This insulation takes up mold which prevents this condition from happening inside your home; this saves you from all the hassles of changing your walls many times. This can also strengthen the foundation of your home which is a practical way of creating a sturdy home. But the best feature of this product is its ability to insulate the house during extreme seasons such as the winter and in the summer. This is the reason why most of the people prefer spray foam insulation as an added feature to their home. The R-value represents the thermal resistance of the material. So the more resistant the material, the higher the R-value is, the more insulated your home is, which is the main essential function of this product. This saves the energy consumption at home. It lessens the consumption of heaters during winter and air conditioners during summers. However, this product has some safety and environmental health concerns such as the toxicity of these materials to those people who are directly exposed to them. But if careful installation is done and limitation of environment exposure is observed, this product is safe for insulation. So how much will the spray foam insulation cost you? Before you think about the amount of money you are going to invest in these materials, determine first the area of your house you want to be insulated. This give you an overview of the budget for the total spay foam insulation cost. These materials cost about $13,000 - $15,000 to insulate a standard home. This is more than half the cost to install other types of insulation materials like the fiber glass insulation. Be reminded that the price of labor in installing these insulators cost more than the insulator material itself since you need to depend on professionals in installing the spray foam insulator.
Can You Paint Slate Tiles?So, 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.
Fireproof Insulation Materials (with Pictures)After long hours of searching you have finally landed in the right place. At last the elusive answers to questions on insulation and spray foam are here awaiting your approval. These aren't the usual newbie FAQ's. These are the 'technical' questions only the really savvy home renovators ask. No more intense bouts of frustration where you suddenly find you're banging your head on the keyboard. The real answers to the advanced questions are here, so say goodbye to impressions of little squares on the forehead. Does spray foam release any Volatile Organic Compounds (VOC)? Polyurethane foam is not considered to emit VOC's. However, during application some spray foams release VOC's through the process of discharge from the canister. After curing there should not be any further emissions. To be sure, check with your foam supplier. Can it be used to insulate underground water pipes? Yes! Work closely with the polyurethane manufacturer to determine the best method of application and the most beneficial kind of foam to use. Regional climate changes and projected temperature extremes will be a part of the decision making process. During application, be sure to prepare the trench properly so that no moisture is allowed on or in the foam until it has cured. Should fibreglass insulation be removed before applying it? Yes! Many contractors opt for leaving blown in insulation in an attic and spraying the foam on top. The problem that arises is ventilation and temperature control. More clearly, the temperature of the attic floor will be different than amidst the fibreglass and the temperature amidst the fibreglass will be different than above the spray foam. The job of the spray foam is to balance temperature and humidity with the environment so condensation is prevented. With an inner layer of fibreglass, where air flows, the conditions would be perfect for moisture formation. Does the surface where it will be applied have to be clean? Yes! Any oil or dust on the application surface will prevent the spray foam from adhering. For the typical attic in a wood frame home, a careful vacuuming job covering every nook and cranny will often be adequate. For applications where the surface is steel (or any other metal) it is even more important for the surface to be free of dust and oil. In some cases where the steel is very new, a coat of primer will be required. Many spray foam manufacturers offer a simple rule: if it can be painted, it can be spray foamed. Does an attic need to be vented if spraying foam on the rafters? That depends. If you are applying the spray foam to the roof deck and gable walls, then you want everything under that surface to be a part of the temperature conditioned space. Vents in an attic with insulation above it would be much like have open windows year round - a total waste of money. If you are applying spray foam to just the attic floor, then the conditioned space is below the attic floor. Vents will be necessary for preventing excess humidity. Is weather a factor when applying it? Water is the most important consideration, either as rain or condensation. If there is any moisture present on the application surface, the spray foam will not adhere. Most of the time the problem will be seen right away, and the installer can stop the job until the surface is dry. In the case of applying spray foam to the exterior of roofs and walls during the construction process, wind will be a major factor as well. Overspray carried by wind can not only affect surrounding surfaces, it can mean a loss of yield. Ambient temperature plays a role as well, albeit in extreme conditions. Exceptionally hot temperatures can cause the foam to not hold shape, cause risk to the installer in enclosed hot places and even risk explosion of the tanks holding the polyurethane. Freezing temperatures, such as in northern Alaska, may cause the applicator to cease working altogether. The substrate temperature is a factor as well. For unique situations such as these, it is best to consult with the manufacturer to see how best to proceed.
