Benefits of Thermal Insulation

Thermal Insulation is the technique that prevents heat moving from one place to another. Due to insulation, room remains cool in summer and warmer in winter than outside. Hence, a room provided with thermal insulation and gives comfort in summer and winter. Thermal insulation is very much important where the temperature varies from one area to another. It helps to protect the constructional material of buildings from the outer temperature.

The main role of insulation is to conservation of energy which leads to decrease in heating demand and the protection of the environment. The reduction of heat transfer between objects in thermal contact. In India plays an important role that provides a region of insulation in which conduction is reduced and it is reflected rather than absorbed by the lower temperature.

The insulating capability of a material is measured with thermal conductivity. Considerations regarding building and climate should be average climate conditions in the geographical area that location and the temperature the area is used at.

The thermal materials used to reduce the transmission of heat into the place that offers resistance to heat transmission. Many times the best thermal insulation could not block the heat completely. Every material transfers some heat of temperature that has a higher temperature on one side than the other. Heat always moves from a hot region to a region that is less hot.

In other situation the heat moves from the hotter region becomes cool and the cooler region will increase in temperature. The main aim of thermal insulation is energy conservation leading to a decrease the heat as well as the protection of environment which is the main objectives of thermal insulation in India in new buildings as well as in renovating the buildings increases the life of building.

Following are some advantages of thermal insulation:

·         Energy Saver: the biggest benefit having thermal insulation is the transfer of heat from inside and outside of the room is restricted which results in less quantity of energy and required for maintaining the desired temperature in the room.

·         The most efficient of heating and cooling system less heat escapes or enters a building.

·         It prevents from thermal stress on roofs due to thermal stress that tend to crack which could be reduced to a great extent.

·         It prevents the transmission of heat from exterior building walls, which capture the heat energy from the sun.

·         Thermal insulation is non toxic and environmental friendly in nature.

·         Thermal insulation prevents the escape of hot or cool air from the interior rooms to the outside.

What Kind Of Roof Insulation One Should Choose For A Commercial Entity?

Roofing insulation provides lots of advantages and wise usage of the right insulating materials for the roof. It can also help in saving energy bills for the long run. Of the various kinds of roofing insulation materials available in the market, foam insulation has the most powerful insulating value. With the ever increasing price of the electricity during recent times, people are making endeavor to cut down on cooling and heating costs. Foam insulation is very easy to be installed. They are strong and last for a long time. If your present roof is not insulated, then you can consider of installing some roofing insulation for improvement of its insulation effect.

Most of the people are wary about installation of new roofing insulation on already present roofs as they feel it could change the look of the house. In fact, this is false for an expert contractor. He can do the installation of the roofing insulation without changing the external look of the house as it remains fitted under the existing roof. Those people living in mobile homes such as caravans require installing roofing insulation since caravans are susceptible to hot or cold as they have thin walls. Suitable insulation will keep caravans warm or cool depending on the outside temperature.

While thinking which commercial roofing system is suitable for your wants, it is significant for you to look a variety of factors, which includes the building type, the environmental impact of a roof, insulation value, amount of foot traffic and ease of installation. Remember that a commercial roofing system is much more than simple roofing. There are lots of parts which should be pondered over. Many low-slope commercial roofs have three primary components - surfacing, reinforcement and weatherproofing.

Roofing Insulation Material

Each and every part is significant for the roofing system. Weatherproofing is very significant component as it prevents water from getting into the roof assembly. Reinforcement provides stability and protection against punctures. Surfacing protects the weatherproofing from weather conditions and increases solar reflectivity and fire resistance. Every part of the commercial roofing installation process is executed very carefully and pursues guidelines made by warranties of manufacturers. This helps in building commercial roofing systems which last longer and need fewer repairs. Every project is unique and carries with it unique requirements.

The Basics on Insulation and Energy Efficiency

Heating and cooling a home accounts for as much as 50 percent of a household utility bill. Stopping energy leaks with proper insulation can cut heating and cooling costs by as much as 20 percent, while improving overall comfort in the home. When selecting an insulation and installation strategy, it is necessary to first understand how a building's insulation impacts heating and cooling. Location, structural specifications, and budget are key factors to selecting the right insulation.

How Insulation Works

A dynamic energy force, heat seeks equilibrium and will always flow from warm areas to cooler, until there is no temperature difference. Its three primary means of movement are convection, conduction, and radiation.

Convection describes the movement of heat through liquid and gas, while conduction is the same movement through solid materials. When people say that "heat rises," they are describing one of the most common behaviors of convective heat - that cooler, denser air displaces warmer, lighter air, causing it to rise. Radiant heat travels in a direct line, transmitting heat directly to objects in its path. The light and heat transmitted by sunshine is an example of radiant heat.

Effective insulation of a home will deal with all three of these transmission properties, with specialization based on particular location characteristics. For example: when looking to cut cooling costs where persistent southern exposure exists, creating barriers to the natural, radiant heat is key. Most commonly, though, it will involve stopping energy leaks in the forms of conductive heat loss or gain. Radiant barriers, such as reflective panels on a roof or planted shade-generating trees, are some common methods of insulating from external radiant heat sources.

Bubble Wrap Insulation

Types of Insulation

Insulation is graded based on the insulating material's effectiveness in stopping heat flow. This thermal resistance is known as an R-value-the higher the R-value, the greater the insulation. The total R-value of an installation is based on the thickness and layering of insulating materials used. The more layers installed, the greater the R-value, and the greater the energy savings.

Optimal installation targets a structure on multiple fronts. While bulky, heavy insulation-known as bat and roll blanket, after the common practice of unrolling large spools of the material by hand-is most popularly used in large, open spaces of a building, such as the roof or crawlspaces. Spray foam has traditionally been utilized for filling smaller, more specific spaces, although recent advances in foam technology has led to an increase in demand.

Considered one of the best methods for insulating a home, spray foam has been found to insulate twice as well as other types. Spray insulation's major advantage is its ability to expand to fill spaces without creating air pockets or open spaces. Additionally, spray foam technology has evolved to include open and closed cell foam compositions and environmentally friendly options. Spray foams are also considered to be more mildew and mold resistant than traditional insulation, and they provide a better noise barrier.

Reflective Insulation Is the Newest In Insulation

Reflective insulation is designed to reflect radiant heat into or out of your house through simple physics. Traditional insulation traps the hot air, preventing it from moving up and through the ceiling into the house. At least until it can't hold anymore air. At that point, the hot air begins to seep through your ceiling making your house warmer.

At the same time, in the winter as the hot air moves up towards the ceiling, that same insulation will eventually let the hot air seep into the attic space, making your house cooler. This can all be solved with properly installed reflective insulation.

Just as its name says, it reflects radiant heat. When installed along the inside of your attic roof, the radiant heat from the sun is reflected back out of the house. This keeps your traditional insulation from absorbing large amounts of heat, which in turn, helps keep your house comfortably cool in the heat of the summer months.

Now the same principal applies when the insulation is installed above your traditional insulation. However, instead of reflecting the heat up and out of the house, it reflects it back into the insulation. Thereby causing your traditional insulation to absorb the heat and send it back into your house, keeping your house toasty warm on those cold winter nights.

No matter what type of climate you live in, reflective insulation is designed for you. Easily and quickly installed, it will save you money on your energy bill. And who doesn't like saving money?

Beyond saving you money, reflective insulation is a simple step in going green. It not only saves energy while being used, it also is greener to produce than traditional insulation, and can be recycled. All of these things combine to make your carbon footprint even smaller, which is a win-win situation.

Why Home Insulation is Necessary?

Before knowing the importance and benefits of home insulation, it is important to know what home insulation is. Home insulation or building insulation refers widely to insulating building parts like ceiling, roof or wall for various purposes like thermal insulation, acoustic insulation, etc. Insulation is basically done to resist the flow of heat and keep your home or work place warmer in the winter and cooler in the summer.

There are several kinds of materials used for insulating homes. These materials are used with building material during construction of a house. One can also insulate one's 5- 10-year-old house. There are many benefits attached with wall insulation and roof insulation such as it improves comfort in the house during summer and winter by controlling room temperature, it offers healthier environment and maintains acoustic effects in the house. In addition to those, it saves energy and lowers down the energy bills. In a way, it offers lifetime energy saving facility. Before selecting items for thermal insulation, keep in mind that material should offer ease in its application, has excellent thermal performance, should be cost effective and safe to apply.

Insulating homes saves energy as well as maintains room temperature according to the requirement. Heat energy generally flows in the direction from high temperature to lower temperature area. There is no use of placing a heater in the room if your home is not properly insulated. The heat emitted from heater will travel to all the directions, to the widows, doors, ceiling, etc. To store the heat inside the room, it is very important to put barriers, which can contain the energy inside the house. This barrier is broadly known as insulation. Insulation materials stop the flow of heat or slow the down it. Not only this, in summer season, it stops or slows down the heat energy transmitting inside the room and keeps room cool in summers. If your house walls, ceiling, and roof are not properly insulated, the energy used in heating or cooling home will not able to give you maximum benefits, and addition to that, you will have to pay hefty electricity bills.

What Are the Benefits of Foil Insulation?

Things like recycling and carpooling are both important aspects of the latest "going green" trend. But what about doing something on a larger scale? What about making great changes that will achieve greater rewards, both for your wallet and the earth? As people build new homes and industrial buildings or even as they begin to remodel and update existing structures, they're looking for ways to improve efficiency and cost, as well as "greenness."

One of the most important ways to do that is by using foil insulation. Fiberglass insulation has dominated the market for years and years, but reflective foil bubble insulation is becoming a strong competitor. The benefits of foil insulation vastly outweigh those of traditional methods of insulation, and people are making the switch.

Reflective foil bubble insulation works differently and more efficiently than traditional forms of insulation. Rather than using thickness and density to block heat transfer, foil bubble insulation uses its reflective color as a way to block the heat from invading your cool space.

In addition, it is all around safer and easier to use than any form of traditional fiberglass insulation. It's stronger, yet lighter and it's much cleaner and easier to install. Reflective foil insulation requires no special clothing or protective gear to install and poses no risk to a person's lungs, skin or eyes, the way traditional insulation may.

Reflective foil insulation is proven to reflect 97% all of all radiant heat that reaches a structure, meaning that it will prevent that heat from penetrating its barrier and either entering or leaving the home. The primary advantage to reflective foil insulation over traditional styles is that it is made to reflect heat rather than simple resist it. This is a far more efficient and effective way to prevent heat gain or loss within a home or building.

In a simple pro and con test, it's obvious that reflective foil insulation is the best choice for insulating homes and buildings. The benefits are endless and the risks are few and there is no reason not to make the switch. For this reason, people all over the world are using foil bubble insulation and reaping the financial and economical rewards.

Importance of Insulation

Easy and Cost Efficient Attic Insulation for Better Energy Efficiency

I am glad to write on a topic that interests me a lot. People do not understand the importance of attic insulation and my following post is sure going to be an eye-opener. If you are planning to insulate the home, do not ignore the attic roof insulation. Insulating the roof is a silent savings bank which helps to maintain the coolness of the home during summers and reduce the energy bills. Every penny saved on the energy bills adds up to become a good saving amount.

Why insulate your attic?

Attic insulation was never on the to-do list of the homeowners. The attic was considered to be a place to dump unwanted things. But, today lot of that has changed as people have understood the significance of attic insulation. To keep your home cool in summer and warm in winters, home insulation is essential. But, if you are not ready to plunge into a heavy investment of complete home insulation then least you can do is the attic insulation.

It is true and I know by my experience that attic insulation is the cheapest upgrade of your home insulation and can work wonders on your energy bills. Next time you sweat out seeing your energy bills then make sure that attics are insulated. Insulation of attic acts like a woollen coat for your building and keeps the interiors warm and comfortable during winters. However, you must look into certain aspects to make attic insulation effective.

Attic insulation improves air quality

The attic is prone to a lot of allergens as they tend to be dirty and dingy. If they are not sealed and insulated then there are chances of the air flowing from the attic to the living space and causing bad odour and temperature variations. Another problem with attic is the issue of infestation of rodents and other pests. Only proper insulation of the attic helps in keeping the rodents at bay. You can also help in maintaining a clean and healthy ambience inside the home.

Tips to help reduce my utility bills

During the winter and summer months, you constantly battle your need to stay comfortable and the need to keep your energy costs down. You do not want to be too hot or too cold, but each year you find your utility bills growing. Some of these costs can be controlled and reduced by making your home more energy efficient. The more energy efficient your home means the less time your air conditioning and furnace spend heating and cooling your home. One key thing to having an energy efficient home is keeping your climate-controlled air in and the less comfortable temperatures outside of your home. Here are some tips to keeping your utility bills under control.

Insulation

If your home is older, you might find that the insulation originally installed in your home is not sufficient to keep your home energy efficient. In fact, some of your original insulation may have disintegrated. Even in a newer home, there might be areas that can benefit from additional insulation. Many companies that install insulation will be more than willing to come to your home and evaluate the current condition to determine if you will benefit from installing additional insulation.

Heat rises, and in an uninsulated home, a quarter of heat is lost through the roof. Insulating your loft, attic or flat roof is a simple and effective way to reduce heat loss and reduce your heating bills.

Insulating your home is one of the best things you can do to reduce your energy bills and it'll make your house warmer and more comfortable, while also reducing its impact on the environment in the process.

The easy way to prepare for Summer

When summer’s heat arrives, it can make your air conditioning unit work harder than it should to keep the interior of your home comfortable. However, there is a way to help your home feel more comfortable for you and your family. And that is with insulation. While many home have insulation, you should check to make sure that it is enough. And if it is old, it may need to be replaced, or your home may simply need more to prepare for summer. There are five main locations where you can add insulation and that is your attic, walls, floors, crawlspace and basement. Sealing windows, adding window coverings and using eco-friendly accessories are other ways to ready your home for summer.

Attic Insulation

A home’s attic is the most important area to insulate. As sunlight shines down on your home, roof temperatures during the day can exceed 140 degrees Fahrenheit. When the temperature drops at night, the heat that your roof absorbed during the day is released, so if the insulation in your attic is old or diminished, then heat radiates down into your home. If your attic is properly insulated, your home will stay cooler.

Wall Insulation

When your appliances use less power to maintain your home’s interior temperatures, your power bill will likely decrease. While there are five main places to insulation, after your attic, walls would also be considered a must. This is because proper insulation in your house can lower your utility bills by as much as 20%. And in addition to energy efficiency, insulation in your walls also helps reduce noise within your home.

Other Ways to Prepare for Summer Heat

Windows are another area of your home that lose cool air. To prevent this loss, make sure your windows are sealed. If your home’s windows are not double-glazed, use polyurethane panels. These form a seal around a window’s frame to stop air leaks. Because windows absorb heat, consider investing in blinds or thick curtains to rebuff heat. And if you have a fireplace, consider installing a chimney balloon as the device will stop cool air from exiting through this opening.

What are the benefits of radiant barriers in attics?

In hot climates, benefits of attic radiant barriers include both dollar savings and increased comfort.

Without a radiant barrier, your roof radiates solar-generated heat to the insulation below it. The insulation absorbs the heat and gradually transfers it to the material it touches, principally, the ceiling. This heat transfer makes your air conditioner run longer and consume more electricity.

An aluminum foil radiant barrier blocks 95 percent of the heat radiated down by the roof so it can't reach the insulation.

In summer, when your roof gets very hot, a radiant barrier cuts air-conditioning costs by blocking a sizable portion of the downward heat gain into the building. In the warm spring and fall, radiant barriers may save even more energy and cooling dollars by increasing your personal comfort. During these milder seasons, outdoor air temperatures are comfortable much of the time. Yet solar energy still heats up your roof, insulation, attic air, and ceiling to temperatures that can make you uncomfortably warm. An attic radiant barrier stops almost all of this downward heat transfer so that you can stay comfortable without air conditioning during mild weather.

You may also find that radiant barriers can expand the use of space in your home. For instance, uninsulated, unconditioned spaces such as garages, porches, and workrooms can be more comfortable with radiant barriers. Because radiant barriers keep attics cooler, the space is more usable for storage.

Roof-radiated heat also warms ductwork or mechanical equipment (air handler) in your attic. The proportion of the total heat gain the ductwork represents, compared to heat gain to the interior of the house, varies depending on the amount of attic and duct insulation you have.

How do radiant barriers "block" heat transfer?

Aluminum foil, the operative material in attic radiant barriers, has two physical properties of interest here. First, it reflects thermal radiation very well. Second, it emits (gives off) very little heat. In other words, aluminum is a good heat reflector and a bad heat radiator.

Your grandmother probably made use of these properties through "kitchen physics." She covered the Thanksgiving turkey with a loose "tent" of aluminum foil before she put it in the oven. The foil reflected the oven's thermal radiation, so the meat cooked as evenly on top as on the bottom. She removed the foil briefly to let the skin brown, but when she took the bird from the oven, she "tented" it with foil again. Since aluminum doesn't emit much heat, the turkey stayed hot until the rest of the meal was ready. To understand the concept of not emitting heat, let's use an analogy of a light bulb. When you turn on a light bulb, it emits light. If you paint the light bulb black, when it is turned on, there is no light emission. A radiant barrier has a similar effect on infrared heat. Your roof surface heats up in the sun and will emit infrared heat. When this infrared heat heats the radiant barrier it will not emit, or reradiate, the heat into your attic.

Cooking a turkey and painting light bulbs are simple analogies, but the same principles of physics apply to an attic radiant barriers. Aluminum foil across the attic airspace reflects heat radiated by the roof. Even if the radiant barrier material has only one aluminum foil side and that side faces down, it still stops downward heat transfer because the foil's low emissivity will not allow it to radiate the roof's heat to the insulation below it.
