Fall Creek 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 Make a Spray Foam TreePolyurethane foam (PUR foam) had been widely used in most household and building installations. There are two types of polyurethane depending on how it is applied, the rigid form and the spray foam. Spray foam application is usually cheaper though less effective. Polyurethane foam is an insulation material with high thermal resistance because of the low-conductivity gas present. It is available in liquid formed but is applied using a spray equipment. HCFC or hydro chlorofluorocarbons are the usual gas used with an R-value range of R-7 to R-8 per inch. This R-value deteriorates in time through the process called thermal drift. As the low conductivity gas escapes through the air, gas molecules present in air replaces the gases in the insulation. This phenomenon usually starts after 2 years of installation. While the rigid board structure is more effective in insulating, application of spray polyurethane foam insulation relatively is easy since it molds to the form of the surface. Because of that it is also called, foamed-in-application. Most of the spray foam produce today has non-CFC (non-chlorofluorocarbon) gas as their foaming agent. While these non-CFC foams are less effective in insulation, they pose less threat to the ozone layer. It is also effective in a relative large range of temperature. An R-value of R-6 to R-6.5 per inch is normal for high density closed-cell PUR foam, about 32 kilograms per cubic meter (kg/m3). Low density open-cell PUR foam has about 8 kilogram per cubic meter (kg/m3). This has been noted to be more flexible than the regular polyurethane foams. Carbon dioxide as also been used as a forming agent for some low density foams. Spraying the polyurethane foam requires specific equipment and personnel using them must be properly trained. High density foams have usually slow-expanding capabilities. Low density foams expand rapidly when applied to walls' cavity sealing them almost instantly. However may cause over-expansion in the walls' surfaces creating damage. Using spray polyurethane foams in home insulation benefits the owner in many ways. Non-CFC foams are eco-friendly have no formaldehydes that may damage the ozone layer in the atmosphere. It can greatly eliminate air or wind infiltration the household. Air seeping through cracks or opening in the walls or roofing can increase convective air currents in attics or walls and also increase moisture and condensation rate inside the household. Since it is a very effective insulation, less energy can be used in terms of cooling and heating the household, while maintain the preferred comfort zone inside the house. It also passively strengthens the walls they are applied to. It has also long life span of more than 10 years which can be extended further by recoating. Installing or using spray polyurethane foam insulation, however must depend and customize to fit the home's building lay-out, cost of effectiveness, and even the climate wherein the home stands. While these considerations can be easily dealt with especially for someone with high budget, application of spray foam polyurethane, for best results must be left at the hands of experts.
How to Fix Holes in Tree TrunksDo 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.
Homemade Rat and Mice Spray Repellent (with Pictures)If you are in the process of building a new home or renovating your existing home then finding the ideal insulation is one of the decisions that you will have to make. There are several options available to you. Some products are more affordable in the short term but don't always provide the best long-term insulation solution. Other products may be more expensive to purchase but can save you hundreds of dollars on your utility bills over time. It is useful to compare and understand the different types of insulation so you can make an informed decision that will benefit you in the long run. What Is Spray Foam Insulation? Spray foam is a product that has been around for some time. It is one of the more efficient home insulators and available in a variety of types to suit different applications. It is made up of at least two compounds. Independently, the components can be stored for a relatively long period of time; however, when the compounds are mixed, they react and form foam that needs to be applied immediately. The foam is sprayed on to a surface area and after a short period of time, it sets and hardens. The result is an effective insulating layer that is highly durable. How Does Spray Foam Compare to Other Types of Insulation? Insulation is rated in terms of an R-value. The higher the R-value, the higher the density of the insulator and therefore the higher its effectiveness. It is considered a good insulator because of its comparatively high R-value. Open cell spray foam which has the lowest density has an R-value of 4. Most other types of spray foam have an R-value between 6 and 7.7. Compare this to fiberglass batting which is another common form of insulation that only has an R-value of 3.5. Comparatively speaking, it therefore has an average R-value that is almost double that of fiberglass batting. Another benefit of spray foam is that the application process is much easier. It can be applied to most surfaces regardless of whether they are horizontal or vertical. In all instances the foam can simply be sprayed onto the area that needs to be insulated. There is no measuring and cutting of mats or the need to overlap insulation. It is easy to apply in a uniform manner. It is also generally more durable than other forms of insulation. It does not wear down as easily and therefore protects and insulates your home for a much longer period of time before needing to be replaced. What Makes Spray Foam So Efficient as an Insulator? One of the properties of spray foam is that as it is applied to a surface area, it continues to expand. This means that the foam can get into cracks and crevasses and provide an airtight and watertight seal. It also hardens in a relatively short period of time which means that the application process can be completed in a relatively short space of time. Compared to other types of insulators, its high density is perhaps its most important characteristic. It keeps cold air out and warm air in during the winter months and helps to effectively insulate your home. How Else Does Spray Foam Protect Your Home? Certain types of spray foam have microbial agents as components. These microbial agents help prevent the growth of mold in your home. If you live in a region that has consistently high levels of humidity then your home can be susceptible to mold infestations. Often mold goes unseen and undetected until it is quite severe. This can affect the health of your family. Having an insulator that prevents mold growth can provide a healthier home environment. Spray foam is highly durable. It also can form a protective barrier in your home against vermin and insects. Rather than having to call exterminators, you can pre-empt the problem by insulating your home with this product.
