All About R-Values

R-Value insulation is the standard type of insulation in homes. In essence, this is a measure of a material’s resistance to the heat flow whether by conduction, radiation or convection. It is thermal resistance in values. These values are synonymous, are reflective of a material’s thickness and density.
However, insulation experts understand that not a single installation can work correctly to keep off the bone-chilling cold of the winter. The best insulation systems, therefore, depend on cost, the condition of the moisture, as we as the material you will be installing. A proper approach to home insulation should help to reduce your energy bills.
To determine what type of insulation you need and where exactly, only a qualified home energy auditor can help. They will carry out an energy audit and assessment. Through this audit, the experts will identify energy loopholes that need to be sealed.
When it comes to choosing insulation materials, the higher R-value, the stronger the insulation is deemed to be. That means that the insulation materials are likely thicker and efficient in energy preservation. The heat resistance of insulation is measured as RV per inch. For instance, spray foam is a better insulator at R-6 per inch than cellulose at R-3.8 per inch.
The higher R-value, much more amount of the material that will resist heat loss. Measuring by the Inch or the Total R-value, R-value can well be measured in a different way. Different types of insulation has an R-value per inch respectively. Cellulose has an R-3.8 per inch of the insulating value while on the other end spray foam has like R-6 per inch that is higher.
Besides R-value per inch, the strength of insulation can simply measure by total R-value. For instance, a 3-inch thick fiberglass wall in a 2X4 cavity will have an R-value of R-13. If the area 2X4 space were filled with the spray foam, the insulation would be R-21.

These figures open our eyes to crucial facts. First, is the fact that there are different ways of determining the energy efficiency of an insulation material. Second is that you need an energy audit professional to assess the areas of need be it the wall, the floor or the roof area.

The United States Department of Energy is now concerned at the rate of energy consumption in homes. Across the world, the costs of energy have skyrocketed, and climate change is worsening hot on the heels of time. For that reason, the United States Department of Energy is now putting in place new standards and recommendations for home insulation.
The rule of thumb is to always have a much higher level of the insulation during the cold months. That is how you can save energy and keep the earth green.

Our experts will conduct a comprehensive energy audit and carry out insulation according to the new standard set by the United States Department of energy.
