Lawrence 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.
Fireproof Insulation Materials (with Pictures)When you're planning to complete any home remodeling or building project, you'll need to understand the insulation needs for your particular venture. While traditional insulation certainly has its place in modern construction, it is often not the best choice. Spray foam is actually a better choice in many circumstances, giving you more effective insulation at a lower cost. Foam is an efficient method for insulating your home, and it presents a number of advantages over more traditional insulation materials. There are, of course, some downsides to the use of spray foam in certain cases, and understanding the pros and cons associated with your insulation choices will help you make the appropriate decisions for all of your projects. Foam is an extremely efficient insulating material. It excels at blocking heat, and helps prevent excessive heat from entering the home. It can also help keep the internal temperature steady, preventing heated or cooled air from escaping the home as well. The measure of a material's ability to maintain the internal temperature of your home is actually called the R-value, and represents the material's effectiveness in blocking heat. The R-value represents the amount of heat or energy the material can block, measured against the space of the material. With spray foam, the R-value is very high, making it a highly effective method for insulating large spaces. The nature of spray foam additionally makes it a good choice for adding insulation to existing spaces. Those locations in your home that are in need of new insulation can be tricky to update. Removing walls, ceilings or floor materials in an effort to add new insulation to an existing area means a great deal of work and expense. Spray foam insulation can get these types of jobs done more quickly and with less money invested in construction efforts. Spray foam makes many jobs easier as it can be placed within existing walls and other spaces without requiring access to the entire space. The foam can be sprayed into the space through small openings and then expands to fill the space with the same or better effectiveness as that obtained from a more traditional insulation material. One of the potential downsides of spray foam insulation is that it can cost more upfront than other insulation options. When working with a limited immediate budget, you may need to consider less costly options for your projects; however, you always want to keep in mind the long-term financial implications of any of your construction, home improvement, or home maintenance choices. While installing spray foam insulation in your home can be more expensive upfront than some other insulation options, it is a more cost-efficient long-term solution to insulation needs. Not only does it eliminate some of the costs associated with installing new insulation, by making the process more effective through less invasive methods, but it also gives you highly efficient insulation for years to come. The process of installing other forms of insulation in existing walls and other less accessible regions of the home can result in additional construction costs, as you must remove and replace sections of the wall, floor or ceiling in order to gain access to the areas that are in need of new insulation. By using spray foam, you remove most of the costs associated with accessing hard-to-reach areas. The R-value efficiency of spray foam makes it a good long-term investment. The upfront cost of installation may be slightly higher than with other materials but the savings in home heating and cooling costs in the long run can make spray foam a more effective and efficient choice. Additionally, you should consider using spray foam in those areas of the home that have crevices, cracks, gaps or holes present. Traditional insulation materials don't reach these types of locations with the same efficiency as spray foam. Air and moisture can get trapped in such spaces, presenting issues with heating and cooling your home effectively. Trapped air and moisture make it more difficult to keep internal temperatures steady. Poor insulation allows external temperatures to leak into the home and internal temperatures to escape to the outdoors. Moisture and condensation that can build up in the cracks, gaps and other empty spaces in the walls, floors, and ceilings in your home can lead to other problems as well. Mold and mildew can result from trapped moisture, presenting issues with not only the efficient heating and cooling of your home but with the quality of the internal air as well. Health concerns surrounding these invasive pests can be serious, and the effort and cost involved in removing mold and mildew greatly exceeds those associated with preventing them in the first place. By using spray foam insulation, you limit the chances of air building up in unfilled spaces within the structure of your home. You also eliminate the concerns associated with moisture being trapped in these types of spaces.
How to Remove Expanding FoamOne of the most important keys to reducing your heating and cooling costs is having your home well-insulated. So what is the best insulation for your home? Spray Foam Foam insulation has two forms: Open and closed cell. Both are made from a polyurethane material and have different propellant agents added. Some are made from biodegradable materials, such as soybeans, to make the off-gases friendlier to the environment. Foam is probably the best insulation for blocking air infiltration combined with high R-value. Installed by a professional, the price of spray foam varies depending on the thickness of the walls and type of foam. Spray foam insulation is probably the best overall insulation on the market if you can afford the cost. Foam insulation lowers your heating and your cooling loads when installed correctly. Additional benefits are elimination of air infiltration, keeps out dust, mold and allergens, and does not sag or deteriorate. Open cell foam is used more in residential applications. It is less expensive to install and is easier to work with after it's in place. Open cell allows water to penetrate, so it makes an excellent roof deck insulator. If water is allowed to penetrate, you can locate roof leaks before the decking deteriorates. Biggest benefit of open cell is heat transfer in sunny locations. It takes approximately 36 hours of sun to penetrate through 8 inches of foam. This is also true for walls. So when the home is cooled, it will stay cool. The warranty of the roof material is not voided with the installation of spray foam insulation. Closed cell foam has a much more structural component to it and can support some weight without compression. Closed cell does not allow water to penetrate and is an excellent insulator for basement and crawl walls where water could be a problem. Closed cell foam has a higher R-value per inch but is very ridged and tough to work with after installation. It is most often used in commercial applications. However, it has its useful applications in homes. Foam insulation keeps mold out of walls. Mold occurs in walls with batt insulation because of "thermal loop effect". This is where the heat penetrates the exterior wall, coming in contact with the cooler interior surface of the drywall, causing moisture to form. Moisture above 25% can provide an environment for mold to grow. Spray foam blocks this heat transfer and has no air gaps in which moisture can form. One way to combat the higher cost of spray foam is to combine a couple of inches of closed cell foam with fiberglass batt insulation installed over the foam, getting the exceptional air-blocking value of foam, with the high R-value and lower cost of fiberglass insulation. Spray foam insulation costs more than fiberglass batts, but it also has approximately twice the R-value of typical fiberglass batts insulation. By combining the two you will get the best of both. Foam insulation is also particularly good for remodeling projects when there is only easy access to the basement or crawl space and the attic. By blocking the air flow from the top (attic) and bottom (crawl or basement) you stop the draftiness that some older homes have, thus making the home more comfortable. A more comfortable home is what we all are looking to achieve. Spray foam can give you warmth in the winter and cooling in the summer when combined with the appropriate HVAC system. These systems can be smaller in size when your home is better insulated with less air infiltration.
Can You Paint Slate Tiles?Do 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.
