Government programs in New encourage people to make your home more energy efficient and green. Isolation is an important part of a home energy efficient but more isolation is not always better. Adding insulation and installation of insulation in uninsulated spaces above may be a waste of money and can actually damage home.

Additional insulation reaches a point of diminishing returns. Before the point of diminishing returns, every dollar spent on higher yields isolation, at least a one dollar reduction in energy costs over a reasonable period of time. After the point of diminishing returns, each dollar spent in yields of less than one dollar reduction in energy costs over the same period of time. An investment in additional insulation does sense of financial and energy efficiency after the point of diminishing returns.

A place to start looking for the point of diminishing returns is the Code International Residential (IRC) 2009. The IRC contains minimum requirements for new homes insulation. The isolation of IRC requested is not at the point of diminishing returns but it's close. For example, IRC minimum attic insulation in hot climates is R-30. The increase in I-38 is approaching the point of diminishing returns. Exceeding R-38 can pass beyond the point of diminishing returns and can not significantly improve energy efficiency in hot climates.

We have simplified the eight areas IRC three climate zones because the attic and crawl space requirements are similar isolation in some areas. When insulation requirements in our different areas of the IRC requirements, use the increased needs. Contact your local building official to determine the conditions of insulation in your area.

Our only area covers the southern third of the country and includes states like South Carolina, Florida, Mississippi, Hawaii and most of Texas, Arkansas, Georgia and California. Our area two covers the middle third of the country and includes states like Virginia, Pennsylvania, Connecticut, Indiana, Illinois, Nebraska, Nevada, and parts of Michigan, Colorado, Utah and New Mexico. Our area of three covers the northern third of the country and Alaska.

Attic insulation minimum in our area is R-30. The minimum insulation in the floor in a ventilated crawl space is R-19. Minimum attic insulation in our area two is R-38. Minimum Isolation on the floor in a ventilated crawl space is R-30. Minimum attic insulation in our zone three is R-49. The minimum insulation in the floor on a track ventilation space is R-30. If the production floor in a crawl space does not allow the I-30 to full depth of insulation, then R-19 is acceptable in our areas two and three.

Insulating a crawl space ventilation is more complicated than the simple placement of insulation between the floor joists. This is particularly true in hot humid climates, where the floor joist insulation can allow moisture condensation that can damage the wood and promote the growth of mold. The IRC now allows spaces without ventilation and insulation of crawl. You should do more research on the crawl space insulation and moisture problems before insulating crawl space crawl.

More insulation is best for improving the energy efficiency of a home, to a certain extent. After the point of diminishing returns, investment in energy efficiency techniques can give better returns. In new construction of these techniques include passive solar design, the air in the slim design, high efficiency windows, and attic radiant barriers. In existing homes of these techniques include sealing differences between indoors and outdoors and the attic radiant barriers.

Construction defects put your family’s health and safety at risk and cost you money. Everybody’s Building Code helps you avoid construction defects, whether you do the work yourself or hire a contractor. Everybody’s Building Code explains the International Residential Code in plain language and illustrates it with numerous drawings and pictures.
