Local Watertown Area Insulation Contractors
Watertown spray foam is available in two forms:
Open-cell spray foam insulation has tiny cells that are not completely closed and are less dense and filled with air. This gives the insulation a spongy texture and a lower R-value (although it can achieve a greater R-value if not restricted by space). Low-density, open-cell polyurethane foams are similar to conventional polyurethane foams but more flexible.
Closed-cell spray foam is much denser. It has a smaller, more compact cell structure and has a higher R-value per inch. It’s also ideal for achieving a high R-value in narrower spaces.
A Quick Guide to Self Spray Foam Insulation
Anyone who has sweated or shivered all night trying to sleep in a poorly insulated house knows that insulation is necessary to keep a home at a comfortable temperature. Insulation works by stopping the transfer of heat from one material to another. This keeps warm air generated by a heater from escaping through windows, walls, and ceilings, or keeps cool air generated by an air conditioner from being warmed by outside air entering the house.
Ancient Egyptians were the first to use asbestos for housing insulation and they also used it for clothing and table wares. Ancient Greek and Roman houses invented cavity walls for insulation. These walls are created by building two stone walls, leaving a channel of air in between. Air is a natural insulator, so this trapped air kept the heat generated by fires inside the houses. Strips of cloth were also used in the Middle Ages and again in the Great Depression in America to trap moisture and stop drafts.
Cavity walls were rediscovered in the 19th century and were used to build houses in Europe and America. Rock wool would be placed into the cavities to provide insulation. Asbestos was also used in this way until the 1970s when the harmful health effects of asbestos were discovered. Asbestos is no longer used in home insulation as it can cause a rare type of cancer.
Because energy costs were low in the earlier part of the 20th century, houses were sometimes built without proper insulation. Even in the 1950s, houses were often built with single layer walls of solid masonry and single pane glass windows. Without insulation, these types of buildings allow heat to escape quickly through the walls and windows.
Today, energy prices are much higher, so all houses must be built with proper insulation to keep energy costs down. Many homes use fibreglass or expanding polystyrene foam inserted into cavity walls as insulation. Fibreglass is so effective because it traps air in between the glass fibres and this air stops the transfer of heat.
With today's emphasis on making homes as eco-friendly as possible, insulation is important because it contributes to energy efficiency. Materials such as paper cellulose, recycled cotton denim, and sheep wool are eco-friendly options that are used to fill cavity walls. Making sure that a house is properly insulated, with no leaks or installation problems, both saves on energy costs for the homeowner and reduces the demand for energy production.
Home insulation is one of the contemporary and widespread home improvement techniques in the UK. Adding insulation measures has resulted into curtailing energy and money on energy bills. So what are you waiting for? Insulate the portion of your home squeezing out heat produced in your house. It can be the:
1. Walls of your house that give off 35% of the heat
2. 25% of the heat to escape through roof
3. 25% of the heat to emit from doors and windows
As the temperature drops in the winter months, the heated air goes up. You have to warm it up using heater and consuming energy only to increase your energy bills. Insulating your house means you are adding a layer of heat resistant materials to the areas that send off heat through small openings or holes. Three main types of home insulation processes are --
1. Cavity wall -- The external walls of your house with gaps in between two thin brick walls are targeted to give cavity wall insulation treatment. Small holes are drilled into the external walls to inject insulation materials. This is called blown in home insulation. Blown in home insulation is advised to be done by professional contractors to ensure 100% effectiveness of the insulation. Wall insulation can save about 120 pound on yearly fuel bills plus 800kg of CO2. Insulating solid walls saves even more - 2.6 tonnes of Co2 and 380 pounds on fuel bills.
2. Loft -- Thick insulation materials at least 270mm as per government recommendations are laid in the attic area of the house in loft insulation process. Loft insulation can be done in DIY method except those areas which are difficult to access by a layman. This home insulation completed by following recommended depth can slash energy bills up to 205 pounds a year and 1 tonnes of carbon dioxide.
3. Draught proofing -- Tiny cracks and small gaps around doors and windows can be spacious enough to send off 20% of the heat from the house. Therefore, sealing those draughts to absorb cold air inside will help your building retail the heat air inside. Areas targeted for this home insulation process includes keyholes, gaps around floorboards, small openings around doors and windows.
Amongst these three home insulation processes draught proofing is the cheapest and easiest to install as materials are easily available from DIY stores and insulation process can be completed by users themselves.
Most homes are not insulated properly and any heat that escapes has to be paid for. Therefore, you should fully insulate your home to maximize energy efficiency and minimize your energy bills.
You probably didn't realise that round 50 per cent of heat loss in a typical home is through the walls and loft. The energy companies know this only too well but of course it's not in their interest to tell you. They would rather see you spending your hard earned money paying to heat your poorly insulated house. The more heat that escapes from your home the more you spend on heating the great outdoors and the more money your energy supplier will make from you.
Therefore, it is definitely worth checking whether your home is properly insulated otherwise you are wasting lots of money on heating fresh air. Upgrade your insulation and you will make big savings on your energy bills.
The following are just some areas where you can improve your home insulation to save energy and money:
1. Loft Insulation
Without loft insulation you could be losing as much as 25 per cent of your heating costs through your roof. Your money is literally disappearing into thin air. Insulating your loft is a simple and effective way to reduce your heating bills, which you can even do yourself. Estimated annual savings of $300 - $400.
2. Draught proofing
In a typical home 20 per cent of all heat loss is through poor ventilation and draughts. Huge savings can be made by adopting a few simple draught proofing measures in your homes.
Estimated annual savings of $50 - $100.
3. Double Glazing
Double glazing cuts heat lost through windows by around half. Modernize your windows by replacing all your ordinary windows with argon filled, double-glazed windows to save around 2.5 tonnes of carbon dioxide (CO2) per year for homes with gas heat, 4 tonnes for oil heat, and 10 tonnes for electric heat.
Estimated annual savings of $250 - $400.
4. Cavity wall insulation
Around a third of all the heat lost in an un-insulated home is lost through the walls. Cavity wall insulation is a fantastic way to significantly reduce the amount of energy you need to heat your home.
Estimated annual savings of $250 - $350.
5. Floor Insulation
As we all know waking up in the morning can be difficult enough without having to endure the shock of an icy cold floor prickling at your toes. This problem is due to a lack of suitable floor insulation or gaps and draughts around skirting boards, which together can account for around 15 per cent of heat loss from your home. Both are simple to fix and here's how. Timber floors can be insulated by lifting the floorboards and laying mineral wool insulation (e.g. glass fibre quilt) supported by netting between the joists. Afterwards you should also fill all gaps between the skirting boards and the floor with sealant to block any remaining draughts. Estimated annual savings of $150 - $200.
There are many other areas in your home where you can improve insulation and save energy and money. Individually or in combination by using these techniques you will benefit with immediate reductions to your energy bills. Over the longer term your savings will run into thousands so now is the time to act particularly as global energy prices continue to rise.
Heat Transfer, R-Value, and Spray Foam InsulationOne 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.
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%.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.
Home Insulation and What You Need to Know
Uncontrolled air leakage is the number one enemy of energy efficiency in a home, responsible for up to 40 percent of energy loss. While fibrous batts provide minimal resistance to air infiltration and exfiltration, Spray Foam Insulation completely fills cracks, crevices and penetrations in the building envelope, when properly applied, creating an airtight seal. And because it fills spaces so completely, Spray Foam Insulation also helps contribute to a quieter home by minimizing vibrations and noises that transmit through gaps and cracks in the building envelope. It helps to block exterior sounds such as automobiles, wind, airplanes and any other outside disturbances, giving you a remarkably quiet building. Whether your in the suburbs of Minnesota or in the city of Minneapolis, utilizing Spray Foam Insulation will help the place where you live or work become a much more peaceful place.Spray foam insulation is a great way to save on your energy bills by making sure that any cracks or gaps in your current insulation are filled to prevent heat escaping. Cracks in attics, walls or any area in your home that leads to the outside can let heat flow directly from the property. Here you are basically paying extra heating bills for essentially no benefit. Because of its ability to insulate even the most difficult areas foam insulation is often used to improve existing insulation as well as in new building projects. It will obviously be better for your home to have this insulation installed from the beginning but an upgrade of older insulation can easily be achieved using this versatile spray.is a cost effective and green solution which will effectively insulate even the most hard to reach areas. It will also keep out water. The foam is applied to any area and will then expand within a few minutes to provide a complete seal. The money saved over the long term will far outweigh the higher installation costs associated with foam insulation.Kits which can be operated by a home owner are purchased for less than $2000. They will be sufficient to complete any small insulation project in your property. Instructions are included along with all of the necessary hardware so this one investment will be all that is needed for you to begin saving money immediately. Can you afford not to make it?You will need to take safety precautions when using kits including wearing protective eye wear, gloves and overalls. The procedure will be safe as long as the manufacturer's instructions are followed carefully. The instructions will contain details of how the foam should be applied along with what kind of performance you can expect from it. The procedure generally involves a quick set up of the equipment followed by aimed spraying. The foam will then dry and turn solid within minutes so you can see the results straight away. The procedure is easy to follow even when insulating areas which would usually prove difficult. This is possible without any real issues due to the foam expanding and filling even the smallest gaps once it has been sprayed. As long as you are able bodied and capable of aiming the nozzle at any area which requires insulation then the process should be a satisfying one for you.
