In modern American home heating and cooling of living space accounts for more than 50% of energy consumed. Inadequate insulation or air leakages are leading causes of energy waste in most buildings. Insulation also acts as a good sound barrier, keeping noise levels down. The amount of energy conserve depends on several factors i.e. local climate, the shape and size of building, living habits of residents and type and efficiency of the heating and cooling systems. Heat lows from high gradient to low gradient or from warmer place to cooler place. Polyurethane spray foam is applied by professional using special equipment to meter, mix, and spray foam into right place. Polyurethane foam helps to reduce air leaks. Polyurethane spray foam is the most economical way to fill and close cavities in finished walls. Blow-in insulation is applied with equipment by professionals.

Spray foam insulation is a dynamic insulation product it is unique and environment friendly. Spray foam improves the structure of your home without you having to worry about additional costs. Improperly insulated buildings lead to troubles such as dust, rot and even high energy bills. Spray foam in comparison of spray in cellulose has lot of benefits because spray foam is used as liquid and after spray, it expands to fill all cracks and holes. Cellulose is a more delicate material that is damaged by outside forces where as spray foam is much tougher and is designed to withstand it. Other major factor that builders and home buyers take into consideration if it is harmful to the environment and when looking at spray foam over cellulose is that they discover that one is formed from recycled substances and oils while the cellulose can be unsafe. Spray foam fit in with conventional construction procedures although it is bit costlier than cellulose but pays back in long term by reducing your heating and cooling needs there by decreasing energy bills.

Radiant barriers perform function which is similar to that of conventional insulation. Both are used to minimize heat transfer but both differ in the way they reduce the heat transfer. A radiant barrier reduces the amount of heat transferred in air that is adjacent to the radiant barrier. The primary function of conventional insulation is to trap air within the insulation there by reducing the heat transfer by air movement. The insulation fibers or particles also block radiation heat transfer through the space occupied by the insulation. Conventional insulations are generally rated by their R-value but as the effectiveness of radiant barriers depends on many variables, simple R-value ratings have not been developed yet. Costs of an attic radiant barrier and conventional insulation also differ which is base on several deciding factors.

Closed-cell foams are superior insulators than open cell spray insulators. Open-cell spray foams insulator typically have R-values of 3 to 4 per inch on other hand closed-cell spray foams can attain R-values of 5 to 8 per inch.

Closed cell spray foam is very useful at places where space is limited as a thinner layer of insulation proves equally effective in comparison with open cell spray foam.

Open-cell spray foam is porous in nature and allow water vapor to penetrate the insulation where as Closed-cell foam is non-porous in structure and does not allow moisture to penetrate, form a effectively vapor barrier.

Closed-cell foam is very strong and increase structural strength of building by reinforcing the surface where as open-cell foam is soft with little structural strength.

Open-cell spray foam requires trimming after installation, and disposal of the waste material on other hand closed-cell foam rarely requires any trimming and with produces little or no waste.

• Spray foam saves lots of money on energy bills by reducing heating and cooling needs.

Radiant barriers work on principle of reduction of heat loss due to thermal radiation. All materials give off, or emit, energy by thermal radiation and the amount of energy emitted depends on the surface temperature. In homes, this heat loss generally occurs between the roof deck and the attic floor. During day time solar energy is absorbed by the roof, heating the roof and causing the underside of the roof sheathing and the roof framing to radiate heat toward the attic floor. Radiant barriers is placed on the attic floor and it reflects most of the heat radiated from the hot roof back toward the roof making upper surface of insulation cooler than it would have been without a radiant barrier. This minimizes the heat transfer to the room below the ceiling. A radiant barrier also reduces heat losses through the ceiling in winters. Thus a radiant barrier effectively reduces heat transfer from within and outside of  building.

Polyurethane is a polymer. Polyurethane polymer is formed by process of step-growth polymerization. In this reaction a monomer containing at least two isocyanate functional groups reacts with other monomer containing two hydroxyl groups in the presence of a catalyst. Polyurethanes are mainly used in rigid foam insulation panels, high elasticity flexible foam seating, microcellular foam seals etc. Fully reacted polyurethane polymer is chemically inert. Spray foam is used for thermal insulation of residential and commercial buildings. It is basically of two types’ closed-cell foam and open- cell foam. Closed-cell foam are those in which all of the tiny foam cells are closed and packed together with all cells filled with gas where as in open- cell foam tiny cells of the foam are not completely closed and are broken with air filled in open spaces. The gas filled in close cells helps foam to rise and expand making it better insulator as compared to open cell foam also Closed-cell polyurethane foams are rigid and have greater material strength than open cell Polyurethane foam.

Home energy audit is assessment of energy consumption in home or residential buildings. It enables you to find out new measures to save energy and optimize present utilization of energy to make your home more efficient. Audits alone do not save energy we have to implement the recommendations made in audit to improve energy utilization. Energy Star provides extensive information to enhance energy efficiency, lower energy bills, and increase comfort of homes.

You can get specific recommendations for improving the efficiency of your home by getting energy audit done by a professional Home Energy. A professional auditor uses a variety of techniques and equipment such as Blower-Door testing, Weatherization Programs, Thermal Imaging Video, Duct-Blasting Test, Furnace Flute Testing, Moisture Reading Technology to determine the energy efficiency of your home. Implementing these recommendations can considerably cut your energy bills and save you lot of money.

Purchasing an energy-efficient product or renewable energy system for residential buildings makes owner eligible for a federal tax credit. Residential builders are eligible for a $2,000 tax credit for a new energy efficient home which is able to save 50% energy in heating and cooling of home. Out of the total amount of energy saved, 1/5 of saved energy should come from improvement of building envelope. Federal energy efficiency tax credit is also applicable for contractors of manufactured homes who follow guidelines of Federal Manufactured Home Construction and Safety Standards. A tax credit of $1,000 is applicable to manufactured home achieving 30% energy savings on heating and cooling over the 2004 IECC and supplements or for homes meeting established requirements by EPA under the ENERGY STAR program. It is to be noted that with the exception of the tax credit for an ENERGY STAR qualified manufactured home, tax credits are not directly linked to ENERGY STAR hence a builder of an ENERGY STAR qualified home may be eligible for a tax credit but it is not guaranteed.

Heating and cooling of a home and office building can prove to be a costly convenience, no matter where you live. A poorly insulated building consumes lot more energy in heating and cooling as compared to a well insulated one. It is advisable to pay attention to the quality of insulation in their home or office building. The most notable ability of spray foam insulation is its ability to seal all holes and cracks, be it a large or tiny one.  The primary objective of Spray foam insulation is to reduce heat transfer by stopping air leaks and keep warm air in and cold air out during the winter and keep warm air out and cold air in during summers. Other notable benefit of spray foam insulation is that it is easier to insulate around obstructions, such as pipes, vents, duct work, electrical wiring etc. This remarkably brings down heating and cooling needs of the buildings and energy consumption down drastically. Most estimates suggests the time taken to recover the initial cost of insulating through energy savings is around two to four years but actual cost savings are dependent on a number of factors, including the age and condition of the home, the age and type of windows and doors, and average temperature in that area. Spray foam is far better insulator than any other insulation products available in the markets.
