Spray Foam Insulation - How This Type of Insulation Could Render All Other Types Obsolete
Spray polyurethane foam (SPF) is better than any other type of insulation at reducing air leakage. Spray polyurethane foam (SPF) in Minnesota is a spray-applied plastic that can form a continuous insulation and air sealing barrier on walls, roofs, around corners, and on all contoured surfaces. It is made by mixing and reacting unique liquid components at the job site to create foam.
With foamed-in-place insulation, it is relatively easy to fill wall and ceiling cavities completely. Closed-cell spray foam provides a higher R-value per inch (6.8) than less expensive insulation types like cellulose and fiberglass (3.0 to 3.7).
Home Insulation - Is It Cold Outside?
Spray foam insulation installation in Minnesota saves on energy costs and lowers utility bills. Buildings treated with spray foam insulation typically insulate as much as 50% better than traditional insulation products. Insulation that is sprayed in buildings protects against moisture, which provides the benefit of reducing the chance of harmful mold and mildew. In addition to Minnesota building temperature and moisture control, spray foam insulation is often used to reduce noise. In the United States, homes treated with spray foam insulation often qualify for Minnesota state and federal tax deductions.
Home Insulation - Is It Cold Outside?
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.
Insulation R value guide ratings are used to measure the insulation's ability to resist heat flow. The higher the R value, the better it is expected to perform. Home insulation should be purchased based on the insulation R value guide, and not thickness or weight.
One type of insulation maybe thicker or thinner, but if the R value is the same they should insulate the same. Insulation R value performance testing is done in a 70 degrees Fahrenheit environment with no air movement. However, when you need insulation the most you're generally not in these ideal temperatures or conditions. This can result in the rated house insulation R value being greater than the actual R value. The average recommended R value of insulating material for basement insulation is R-12. The Insulation R value guide in house insulation is a lot lowered when there's any air or water or moisture leakage. The standard R value for house hold insulation varies based on climate and temperature. There are different types of house insulation materials and each one has a different R value.
Protecting your house insulation and keeping your R value high is extremely important for lower utility bills. Water is one of the more important concerns in regards to R value and house insulation. If moisture of any type gets into your house insulation, it lowers the R value. The moisture weighs the insulation down, and as a result it leaves gaps or bare spots. Superseal Dimpled Membrane provides a permanent barrier against water/moisture from entering your home. It protects the home's insulation and its R value by keeping your home dry. Superseal helps protect and increase the life expectancy of your house insulation and its R value.
Approximately 11% of your home is not insulated properly due to wood framing however, wall studs are a fact in home construction. Before you cover up the wall studs, making house insulation diagrams for any future reference is a good idea and saves a lot of headaches. The R values of wood studs act as a type of thermal bridge. The R values of wood can create a what amounts to a cold area in the insulation where the wood stud meets the sheetrock.
The cold spots can lower the effectiveness of the insulation and lower the effective average R values of the whole wall. In addition to the poor R values of wood lowering the R-values of the wall, a cold spot may lead to moisture and condensation problems. Moisture can and will condense through wall studs, which generally have the lowest insulation R values, and other framing materials of the home. If moisture does get into the wall cavity, condensation can occur where the cold R values of wood studs meet the sheetrock.
The R values of wood wall studs are measured in terms of linear inches. However, wooden wall studs generally lower the R values of your insulation. The R values of wood are specified as 1.25 per inch. To help protect against moisture entering your home and further lowering your homes r values, protect your home with Superseal Dimpled Membrane. Superseal provides a permanent barrier around your home and helps protect your homes R values. Just 4% moisture in your insulation could lower its thermal efficiency, in that area, by up to 70%.
It's important to remember when buying home insulation, that the home insulation materials with the highest R value may not be the most cost-effective. When insulating your basement wall to an R value of R-12, it might not cost as much to use 2 layers of home insulation materials with an R-6 R value rating instead of 3 R-4 R value rated home insulation materials. Just because the home insulation is the most expensive, doesn't mean it's the best.
Another home insulation tip is to make sure to buy your home insulation based on its R value not its weight or thickness. Also, if you are installing fiberglass insulation yourself, remember that the fiberglass is made of glass strands. Touching fiberglass insulation material makes you very itchy. This is because the glass breaks into tiny pieces, and gets into your hands or skin. The last and most important tip for home insulation is to make sure to protect your insulation from water and moisture. Just 4% moisture in your insulation can reduce the thermal efficiency, by up to 70%.
Spray Foam Insulation - Open and Closed CellThe 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. Spray foam insulation is a form of spray plastic that can be used as insulation and an air-sealing barrier on roofs, corners, walls and contoured surfaces. It's made by mixing different liquid components that react and quickly form the resulting foam.Types of Spray Foam InsulationThere are two main types; open cell and closed cell (this can also be broken down and classified as low, medium and high-density foam insulation). The less expensive open cell insulation uses fewer chemicals and can be a very effective air barrier, but does not act as a water vapor barrier. Typically it is used for indoor insulation, and can also be a great sound barrier.Closed cell foam insulation has a more dense and compact structure, and can also be used a water vapor barrier. Due to its structure, it can be used both indoors and outdoors (including roofs).Benefits There are many benefits to using this type of insulation in your home or commercial building, but here are a few: First and foremost, in can lower your utility bills. This is because it stops air and moisture infiltration. Studies have shown that without proper insulation, a home can lose up to 40 percent of its total energy due to air infiltration. It adds additional strength to the structure of the building. It can help keep dust and pollen out It's permanent and requires no additional maintenance How Does It Work?Actually, applying this type of insulation is quicker and easier than you may think. As the liquid is sprayed, it quickly transforms into hard, thick foam. It can be used anywhere, however, because of its flammability, it requires an ignition source if installed near a flame source (such as a water tank or furnace).Should You DIY Spray Foam Insulation?There are plenty of DIY foam insulation kits you can purchase, and even more online tutorials that show you how to do the job. However, if you don't have experience working on these types of projects, it's best to go the "better safe than sorry" route, and it is really a job best left to the professionals. It's important for individuals who want to have this type of insulation installed in their homes to contact a professional, as additional gear is required to handle the materials.Spray Foam Insulation vs. Fiberglass & CelluloseWhile it may at first seem tempting to go with a more traditional fiberglass, there are many cons to this option. It's important to understand all aspects of your options so that you can make an educated decision. Fiberglass still allows air to pass through, defeating the purpose of its installation in the first place Because they are made of a combination of old materials, they may not meet changing building codes in your area. While spray foam insulation stays in place and is permanent, fiberglass and cellulose can sag over time, diminishing its overall performance. Traditional insulation can still soak up water, which can lead to mold growth and costly repairs-or worse, the loss of your home. Fiberglass and cellulose can tend to be on the dusty side, paving the way for pollutants to potentially enter the home and trigger allergies. Unlike spray foam insulation, fiberglass can be intruded by pests, and even used as a nesting ground. Spray foam insulation is a smart choice for new builds and retro fits. It is cost effective, safe, and provides excellent insulation properties. With all of the insulation choices on the market today, this type of insulation offers many benefits to today's homeowner.
Insulation and Your HomeIf 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.
