Spray Foam Insulation – Open and Closed Cell

The spray foam insulation kits are your expandable green solution to effectively insulate your home. Its specific formula creates an envelope that you can spray anywhere in your house that needs insulation such as the walls and ceilings. By far, expanding insulation kits are the best and most effective DIY product out there.Most foam insulation (also known as polyurethane foam) comes with a special spraying device, such as in the Handi-Foam E-84 spray foams, that precisely distributes the formula to seal big cracks and holes. As a result, it helps keep the temperature cool during the summer and warms it up when it’s cold outside. When the application is done, the drying process would expand and harden the spray foam making it virtually impossible to remove. That’s the reason why you should always wear protective clothes to prevent it from directly sticking to your body.You need to know that these are not cheap (and it would get more expensive if you don’t know what or how many you’re going to use). Unless you use the proper protective clothing, you can always expect that the process is going to be messy. And too much spray insulation foam on an area could lead to its possible collapse because of rapid and increased expansion.Despite all of that, you are better off with spray foam insulation than fiberglass insulation. The good thing about spray foam insulation is that they can fill even the tiniest gaps and prevent pests from entering your home (you can cross out that pest control bill from your list). Not only is it environmentally friendly, it’s also good for your health because it reduces the possibility of inhaling harmful substances.Now, if you really want to save money, you need to follow some simple guidelines so that you’ll get the right spray foam insulation kits at the first time.The first thing to do on your list is to take your square footage. When we talk about square footage, it means that you’ll only measure the area where you intend to use the spray foam insulation kits.Dirt, scrap materials, and oil – all of these should be swept and scrubbed away before applying your spray foam insulation. Since this adhesive product doesn’t stick on oily surfaces, you’ll be wasting a great amount of money by forgetting to do this important step.Next, you need to decide on the thickness of the application. Most experts would recommend that you spray 1 inch to 2 inches at a time and a maximum of 3 inches.After deriving the total amount of boards required (square footage multiplied by number of inches), you finally have to calculate the number of kits you require.There are many effective products out there that you can find, such as Dow Great Stuff Insulating Foam Sealant, which you can find at Lowes.com. In the end, what makes spray foam insulation kits great is because these are eco-friendly and energy-efficient products. Energy Contractors 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.

If you are in your home when the wind is blowing outside and feel a draft, it may be time to think about insulating your house. Sometimes drafts are hard to nail down. Maybe you check around and can’t decide if its coming form under the door, from the electrical outlet or around the window. Before the wind gets cold in the winter, consider do it yourself spray foam insulation kits.Spray foam kits are a great idea for use around windows and doors. The foam comes in an aerosol type can with a unique spray nozzle that has an extension of four to six inches. This extension lets the foam be very targeted and get into really small crevices and cracks to get maximum coverage. The foam expands immediately upon contact with the air.But there are some things about the spray foam kits you should know: 1. Know exactly where you want to put the foam before you pull the trigger on the nozzle. Make sure you shake the can and then put the extension exactly where you want to put the foam. It expands very quickly and it is extremely hard to remove if you don’t get it in the right place the first time. It is very sticky until it dries. 2. There’s not very much in the can. If you a doing a small window with a minor problem, figure on one can. Even a small window may take 3-4 cans if there are lots of gaps that need to be filled. 3. It’s not cheap. Each can runs between $3.00-$4.50. That works for a small area, but if you are going through 3-4 cans or more per window, you may want consider a different course of action.

A Quick Guide to Self Spray Foam Insulation

Spray foam, also known as SPF or Spray Polyurethane foam is a type of plastic that is applied by spraying it. This material is able to give you a continuous layer of insulation and also creates an air sealing barrier for roofs, walls and around corners as well as on all other types of contoured surfaces. When spray foam is mixed, it expands in order to make a foam that seals gaps, insulates and even forms barriers against vapor and moisture. This type of insulation is proven to resist the transfer of heat while giving you a solution that is highly effective for reducing any unwanted leaks of air from joints, seams and cracks.Different Kinds of SPFThere are three main types of this foam and they are all utilized for insulation as well as for other purposes. Low Density SPF is very often seen being used for filling interior cavities as well as attics that are unvented. Medium Density SPF is also used for filling interior cavities and attics that are unvented but it is also used as a continuous insulation. High Density foam is mainly seen for applications in roofing and exterior areas. Each type of SPF has its own unique properties and benefits that can be explained to you by your professional SPF contractor. This is important to discuss when you are trying to determine which one will be the most appropriate for your needs. Aside from the type of foam, there are also differences in the creation of the foam and how it is installed.There are three different methods of delivery for the SPF. An insulating foam sealant A low pressure – two part foam A high pressure two part foam Again, consult with your SPF contractor to determine the best type and the best delivery system for your specific needs.As a Sealant against Air LeaksAir leaks are known to not just waste energy but also to drive your utility bills sky high. SPF is often used to fill in any gaps as well as to stop air leaks in various areas of a building. Some of the more commonly seen trouble areas for air leaks are: Basement rim joists Basement windows Basement doors Recessed lighting Furnace flues Duct chase ways Open soffits Vents for plumbing Holes for wiring Hatches in attics Behind any knee walls All of these places can be sealed with the use of SPF.Cool Roof EffectCool roofs are a type of roof that has been designed to be able to maintain lower temperatures than that of a traditional roof. They are typically light colored and instead of absorbing sunlight they reflect it allowing the heat to be able to escape.When you apply SPF to a traditional roof, you can actually achieve the performance of a cool roof. The benefits of this don’t end there though. Aside from reducing the need to run the air conditioner, SPF actually assists in protecting the roof from damage and can actually extend the life of it.Spray foam installation is not a job for the average homeowner. This is a job for the professionals who have the right equipment and safety knowledge to get the job done properly and safely. SPF is one of the most economical and effective types of insulation you can choose for your home. Window Insulation Companies

Insulation at home helps in saving energy and reducing utility bills. It makes the house more comfortable. Insulation at home not only helps in keeping the house cool in summer and warm in winter but it also prevents damage from leaking water and provides a good thermal resistance. Insulation is very useful to keep the temperature of the house as outdoor temperature.

By using insulation, the cost spent in cooling and heating the home can be reduced to a great extent. There should always be sufficient insulation at home to protect the house from air leakage, water leakage etc. R value, also known as thermal resistance is used to compute the insulation resistance. It shall be installed between the heated and unheated space.

There are many types of home insulation available. All insulation has pros and cons. They are mainly differentiated based on the material used for the insulation. They can be distinguished into Plastic foam, rigid board, reflective, loose fill, batts and blankets and blown in insulation etc. Batts and blankets insulation can be performed by the homeowner himself. No professional is required for this type of insulation. They are easily affordable and the material like blankets and batt strips are easily available in the market. Batts and Blankets insulation can be performed with the help of materials like Fiberglass, Mineral wool, plastic, concrete block, polystyrene fiber etc.

Fiberglass insulation may cause allergies to the skin if not used properly. Therefore, proper care must be taken while installing this type of insulation. Mineral wool insulation uses natural minerals for insulation. It helps in fire protection and sound reduction but it may result in respiratory problems. Plastic fiber glass insulation is performed with recycled plastic bottles. Loose fill insulations are blown in types of insulation that are mainly made with glass, fibers, vermiculite or perlite. They are mainly used in attics and walls. Cellulosic insulation is made with wood fibers and recycled newspapers. It is insect repellent and provides great resistance to fire due to the chemicals added into it. It does not provide good resistance to moisture.

Reflective insulations are made from aluminium foil and plastic films, cardboard etc. It is very useful in filtering the heat out from the home in summer. But they are a good conductor of electricity so no electric equipment or fixture should be installed near to the insulation. Foam Board insulations use polystyrene material and reduce air, heat and water leaks. They provide good resistance to moisture and can be used on ceilings, floors and walls. They provide strength to the home and provide thermal resistance.

Insulation can be performed at home in attics, on ceilings, exterior walls and garages and storage areas for proper ventilation and thermal resistance. Insulation must be performed either by professionals or proper care must be taken while installing them. Air and water leaks must be thoroughly checked before installing the insulation as moisture can dampen the efficiency of insulation or insulation may mask them. It must be checked that electrical equipment and fixtures are not getting touched by the insulation. Also some insulation can cause allergies to the skin and may cause respiratory problems so proper care must be taken while installing them.

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 FoamFoam 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.

Spray Foam Insulation Alternative for Building Green

Spray Foam Insulation allows residential and commercial structures to be more sustainable by making houses more energy efficient, healthier, and durable than traditionally insulated homes. Most spray foam materials are water assisted and soy-based, so they do not have much of a negative impact on the environment and can provide the homeowner with decreased energy costs in the end.Most traditional spray foam materials are made of glass or cellulose, which are not that environment friendly. However, spray-on insulation, made of polyurethane foam, is pumped through pressurized spray nozzles. Once sprayed, it expands to one hundred times its original size and provides a thermal seal and it utilizes renewable resources. The product also can be water-blown which means it is more environmental friendly than traditional one. When it expands, it fills each cavity, crevasse and hole to create a sealed envelope. If properly installed, most spray foam does not usually foster mold or insects and does not break down, hence creates a sealed interior, blocking unwanted pollution out. Spray foam insulation adheres to most material, such as wood and steel and can be used for new constructions or renovations. If the installation is correct, this product poses few issues with properly installed electrical wiring.Spray foam insulation can seal and fill all the tiny cracks and seams. The material helps to eliminate energy wasting air filtration which can save on framing costs, as well as window and door jambs. This type of product also helps control moisture condensation because it will not shrink and it is fire resistant. In addition, the environment friendly product has been known to alleviate the discomfort associated with indoor allergies and other airborne illness.If an individual decides to get spray foam, they must understand that the initial insulation costs may be higher than with traditional foam material. The initial cost of using it can be more expensive than using traditional materials. Even though it is more expensive, after insulation you could lower your utility bill by as much as thirty percent. This means you could pay back the cost difference within years of installation.Spray foam insulation is also not a do-it-yourself procedure and therefore you can not cut costs by installing the material yourself. The insulation should be installed by independent certified contractors and must take place after the electrical, plumbing and mechanical systems are installed. Only trained professionals should install it because it requires specialized sophisticated equipment to install it properly. In addition, it can be very messy and complicated as well. A contractor should also be trained to ensure that the products are properly installed. You should also work with electricians and plumbers who are familiar with working on this product. Since it is fairly new, there may not be many contractors in the area who can apply insulation.Being a complicated and messy process, it will be easier and more effective in new construction rather than existing homes. Once installed properly, it takes care of the health, safety and comfort of your house. Insulation Contractors Houston The energy conservation industry has experienced explosive growth while continuing to develop new technologies. For the consumer, deciding which materials and devices offer the greatest return on investment can often be confusing.Over the last five decades, thorough research reveals that the greatest energy savings per dollar invested comes from maximizing the insulation value of a home or business. Among the different insulation materials, spray foam insulation offers substantial advantages over competing systems.Heat Transfer: Conduction, Convection, and RadiantThe purpose of any insulating material is to slow the transfer of heat. To compare the relative effectiveness of the different insulation alternatives, it is important to understand how heat moves through materials and space.Conduction:Conductive heat transfer is the process where thermal energy travels through the mass of a material on a molecular level. Conduction occurs when heat passes through a single material or multiple materials that are in direct contact with one another.Conduction is a primary method that heat uses to migrate through the ceiling, floors and walls of a structure. Placing spray foam insulation directly between two highly conductive materials will substantially slow the process, especially when compared to other insulation types such as fiberglass or cellulose.Convection:Heat that moves through the air is called convective transfer. Differing pressures between warm and cold air provide the mechanism for this kind of movement as warm air seeks out colder air. Since warm air escapes through breaches in a building’s envelope, additional fuel must be used to heat the colder air that replaced it.In the cooling season, the convection transfer reverses as warmer air from the outside infiltrates into the home. Spray in foam insulation systems that seal the perimeter of the building are most effective in eliminating convention currents.Radiant Heat:Heat that is transferred through the electromagnetic spectrum is known as radiant heat. This form of heat transfer is best addressed through installing materials with surfaces that have exceptional reflectivity properties.R-Values and Spray Foam InsulationMost insulation systems are designed to address conduction fairly well, while doing a poor job of addressing convection and radiant heat transfer. The insulation industry has adopted a standard called “R-value” which is a measurement of conductive heat transfer through an insulating material over a given period of time. The problem with this standard is where its focus is, conductive heat transfer which is only small part of the pie when it comes to whole issue of heat transfer. Spray foam insulation is the only type of major insulation that performs at a high level across all three fronts of heat transfer: conduction, convection, and radiant heat transfer which makes it the best choice for keeping your home comfortable and your energy costs low.
