Clermont Spray Foam Cost Per Square Foot

Clermont 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 Solvent

House Insulation One 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.

How to Remove Expanding Foam Residue With a Solvent

Spray Foam Insulation Cost Per Sq Foot Polyurethane 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.

Spray Foam Insulation Home Depot 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.
