Fishers 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 SolventThermal Spray Foam Insulation is used in buildings, and refers to the application of thermal insulated materials, which are applied using various spraying methods, into a roof space or wall cavity to prevent heat loss. The application of this process is normally completed within two days. Thermal spray foam insulation does not particularly address ventilation or sound proofing issues. It simply refers to the insulating materials being used to slow heat loss. The effectiveness of it is usually evaluated by its R-value, but this does not take into account construction or local environment factors. Thermal spray foam insulation is easy to apply. Foam insulation is sprayed onto or into the underside of the roof within the attic/loft space, and dries to a rigid foam. Thermal spray foam insulation is an important factor to achieving thermal comfort for the buildings occupants, and thermal spray foam insulation reduces unwanted heat loss, and reduces the energy requirements of cooling and heating systems. Thermal spray foam insulation simply refers to the insulating materials being used to slow heat loss. One of the most effective types of insulation spray is polyurethane foam, which has been specifically formulated for use within the insulation industry. This type of foam is a very cost effective insulation material, and works in two ways by keeping the desired space or area warm in winter and cool in the summer. It can also help with the problems that arise from condensation, and is an ideal solution for ambient and cold storage. Polyurethane foam is easy to apply, lightweight in structure and can cover large areas quickly and efficiently, making it a very cost effective solution for many commercial requirements. The application of foam spray uses a rigid polyurethane foam which sprays to a fine cellular structure with high compressive strength and good adhesion and insulating qualities. Many of these foam spraying techniques and materials do not contain or use any CFCs. Thermal spray foam insulation will adhere to most structures and other materials such as fibre, sheet metal, cement, asbestos sheeting, concrete and steel. When sprayed it can expand to over thirty times it thickness. It is lightweight in structure, weighing only three kilos per square metre at a depth of fifty millimetres. (approx) Insulating a building with this method will help to keep it warm in the summer and cool in the winter, reducing temperature control costs and providing a dry and comfortable environment for staff and workforce, and controlled storage for stock and materials.
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.
Fireproof Insulation Materials (with Pictures)Although spray foam insulation as we know it today truly emerged in the 1980s, spray foam actually has its roots several decades further in the past, beginning with the development of polyurethane foam in the 1940s by Otto Bayer. Otto Bayer, an industrial chemist, actually began working with polyurethane in Germany during the late 1930s. This technology was brought to the United States in the early 1940s by David Eynon, the president of Mobay, a war effort conglomerate created from the partnering of two chemical industry giants, Monsanto and the Bayer Corporation. Although Otto Bayer worked for Bayer Corporation, he was not related to the company's founding family. During the 1940s, polyurethane polymers were used primarily in military and aviation applications. The production of war machines for the World War II conflict drove most of the applications of these high-grade plastic polymers for the duration of the war. It was not until the 1950s that polyurethane began to be used in home insulation. It was the invention of the "Blendometer" that allowed for expansion of polyurethane application to the home insulation realm. The Blendometer was the first machine able to mix components for the creation of polyurethane foam and was created by Walter Baughman in 1953. The Blendometer allowed for the strategic mixing of chemicals to create what Baughman called a plastic elastomer or an expanding foam. Liquid when applied, this plastic elastomer expanded into a thick foam and eventually hardened upon drying. Baughman's Blendometer was still a partially manual process, with humans tilting trays of chemicals to mix foam. While the machine did allow for the use of polyurethane in home insulation as well as in other home-related applications, like air conditioner insulation, it was still a technology in its infancy and one that made widespread use of polyurethane as a residential insulation material no less cumbersome. Polyurethane polymers were used in a variety of means throughout the following decades, with incredible advancements being made in the auto industry applications of the material in particular. However, it would be more than two decades before the foam would become widely used in home insulation processes. Building on Baughman's invention, the first dedicated spray technology machine was constructed in 1963 by Fred Gusmer. The 1960s and 1970s saw technological advancements which made spray foam's use in home insulation more easily achievable and affordable. It was also in the 1970s that the idea of the "super insulated" home emerged. Largely driven by the energy crisis of the 1970s, home builders and homeowners alike began to look for ways to improve the energy efficiency of homes. The crisis fueled advancements in technology that laid the foundation for modern spray foam applications. It was the development of advanced spray nozzle technology that allowed spray foam insulation to be used widely in home construction and improvement projects. The spray foam nozzle allows the foam mixture and the chemical responsible for its expansion capabilities to be separated until just prior to application. The spray foam mixture consists of several key components but it is the expansion chemical, isosynate, which is responsible for its easy application and expansive character. The application nozzle allows the foam mixture and the isosynate to be delivered to the nozzle through separate hoses, mixing only seconds before being sprayed. The spray foam arrives at its destination as a liquid but quickly expands into a foam substance and later dries into a hardened plastic upon curing. The 1980s and early 1990s saw a great deal of controversy within the spray foam insulation industry as different marketing schemes from various companies promoted the benefits of closed verses open foam insulation and as some companies tried to market water blown foam application processes. Though there has been much debate within the industry, R-value standards, used as a measure of determining energy efficiency, have cleared up much of the controversy. R-value ratings clearly define closed foam as the most effective means of making a home as energy efficient as possible. Closed cell spray foam has additionally been added to the list of building requirements for making homes in hurricane and earthquake zones more structurally sound. The improved stability of homes insulated with spray foam technology makes the use of spray foam a smart move for any homeowner regardless of geographic location.
