Carmel 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 Expanding Foam Residue With a SolventSpray Foam Insulation is a two-component system typically consisting of petroleum oils, plastics, and resins. The polyurethane foam comes in two different forms, open cell and closed cell foam. The polyurethane spray foam is an extremely versatile material that is available in a variety of final physical properties and densities. Although the two types of foam are very similar in their chemical structures their characteristics and capabilities differ in many ways, which makes it necessary for the user to understand the differences of the two materials so he or she can determine which is the right foam for their particular application. 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.

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. Although, Open cell foam is an efficient and economical product it contains some disadvantages in regards to closed cell foam. One of the open cells disadvantages is it has a lower R-Valuer per square inch than closed cell foam does and open cell foam is vapor permeable requiring it to be covered with a vapor retardant material. Although, open cell foam has some advantages and disadvantages it has been recognized as an excellent insulator, air sealant and sound barrier. The second type of polyurethane foam is referred to as "closed-cell" or "2 lb foam". The closed cell foam gets its name from its individual chemical reaction. During the installation process the tiny cells that are created during the chemical reaction are not broken and are packed together. These little cells are filled with gas allowing the material to rise and become an excellent insulator. As mentioned earlier the higher the foams density the heavier, or stronger the foam will become. This type of foam carries a density strong enough to improve the structural integrity of the building it is applied to. Due to the higher density of this material it requires the use of more material resulting in a higher project cost. Some advantages of this foam includes its higher R-Value per square inch compared to open cell foam also, this foam is vapor resistant cutting out the additional cost of the vapor retardant material that open cell foam requires and it has the ability to improve the structural integrity of the building it is applied to. One major disadvantage is the products exceptionally high cost. The closed-cell foam commonly carries the highest R-value of any insulation material on the market at a value of 7.5 per inch. There are many things a home or building owner should take into consideration when considering the type of foam that should be used for their particular application. Although both types of foam are by far the best insulators on the market, each type of polyurethane foam possess its own characteristics and capabilities. It is imperative for the user to identify which foam is right for them before applying the product.
How to Remove Expanding FoamWhen 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.
Fireproof Insulation Materials (with Pictures)Expanding foam that overexpands and lands where you didn't plan for it -- on hands, clothes, cinderblock or studs -- can pose a removal problem, with the solution depending on the type you use. Polyurethane foams including Dow's Great Stuff, Touch 'n Foam, DAP Kwik Foam and Owens-Corning Insulating Foam Sealant require solvents to clean up while they remain wet, or uncured. DAPtex, a latex foam, expands less and stays flexible as it dries -- and cleans up when uncured with soap and water. Uncured Uncured expanding foam remains wet and can pose a removal problem on skin, carpet or clothing. Polyurethane foam on rigid and soft surfaces: Consult the manufacturer's instructions, which will suggest solvents, such as acetone, paint thinner or nail polish, to remove uncured polyurethane foam. On soft surfaces, such as carpet, test an inconspicuous area first. Polyurethane foam on skin: Wipe off the foam with a paper towel, and rub off the final sticky layer with petroleum jelly or baby oil. Latex foam: DAPtex can be cleaned off surfaces and skin with soap and water. Cured Expanding foam dries and hardens in 1 to 8 hours, depending on the product. You can sand, trim or scrape cured foam from rigid surfaces. Use a utility knife with a new, sharp blade for overfill up to about 1 inch thick. Switch to a serrated bread knife for wider overfill. If polyurethane foam dries on your skin, rub off as much as you can with a pumice stone. After a week or so, any remaining dried flecks should work off your skin. Tip To clean the nozzle before putting away the expanding foam, home improvement expert Danny Lipford recommends inserting a spray lubricant straw into the nozzle and spraying lubricant through the nozzle, then cleaning out the nozzle with a wire. Wipe off the outside of the nozzle and the straw before storing them. Alternatively, clean the nozzle with a can of compressed air. A DAPtex nozzle can be cleaned with soap and water and a paper clip or pipe cleaner.
