Wynndale Cellular Foam Insulation

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 Expanding Foam

Blow Foam 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.

Spray Insulation Ceiling One of the most popular techniques being used in roof insulation and roof repair is the spray foam roofing system. This technology has been around for many years and has been growing in popularity because of the many outstanding benefits and advantages over other types of roofing applications. When it comes to the foam material being used, most roofing contractors recommend polyurethane foam. To give you an idea what polyurethane foam is, it is a combination of two liquid elements- an isocyanate and polyolresin. They undergo a process of mixing according to its specified ratio which is normally one-is-to-one. The technique is applied by professional applicators using a team of spray foam equipment like a proportioner, heated hoses, transfer pumps and spray gun. Polyurethane foam is very flexible and versatile and can be applied to any type of roofing system. When the liquid polyurethane foam is sprayed over the affected roofing area, it expands and solidifies in just a matter of seconds. What happens next is you see a seamless and durable protective layer. The succeeding procedure is the application of another protective coating like an elastomeric type of coating. That is how simple sprayed polyurethane foam or SPF roofing system is. However, it is risky to undertake this procedure yourself if the extent of roofing repair and insulation is a bit complex. Adequate training, proper technique and application, and years of experience are the credentials brought in by the team of professional roofing repair and insulation contractors. It is the quality of work which will determine if the spray foam roofing will give the desired effects. If it is only the labor cost component you are trying to save when you decide to make it a do-it yourself job, you have to evaluate the situation thoroughly. On the other hand, if the roofing problem is a simple one and you are confident that you can do the procedure yourself, then go ahead. Having the basic technical know-how and skills and the energy are enough to accomplish the job. When it comes to DIY spray foam insulation kits, there are many types available in the market. The most common and affordable are the spray cans. You can shop in your local hardware stores for sealants and foam sprays and the price range depends on the features of the kits. You may want to purchase a kit with a pressurized spray nozzle or spray gun with extra nozzle tips and foaming chemicals. Before you buy what you need, try to familiarize yourself with the best type of kit by learning the appropriate ingredients and other matters such as r-value and other resistance rating. As soon as you are able to buy your kit, the next step is to see to it that the area to be worked on is perfectly clean and free of any debris. Just follow the instruction guideline in the manner of spray technique. The actual schedule should be done when you believe that the weather won't be a problem. For an ideal application, you have to do the spray foam roofing at the right temperature. If your roofing needs an extensive protection and insulation, it is to your best interest to assign the work to the professionals. Do your homework as to which type of foam material you consider the best. If you choose the SPF system together with a reputable elastomeric brand of coating, all you need to do is to finalize a deal with a dependable roofing and thermal insulation contractor for a total project cost within your budget. The bottom line is your house will enjoy proper room temperature during hot or cold days, some sound and noise reduction, wind lift, flame and weather resistance. There are other benefits you will enjoy not limited to reduced energy bills. In effect, the project investment you make is a self-liquidating one. Because of lower energy consumption, you are also helping out in the government's energy security and environmental concerns. What is of prime importance is the big picture. Just visualize the peace of mind, comfort and enjoyment spray foam roofing will provide to your family for many years to come!

How to Remove Expanding Foam Residue With a Solvent

Spray Insulation Foam Cost 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.
