COLD WEATHER?? Check your insulation (ALACHUA COUNTY)
As energy efficiency has become an increasing concern among builders and homeowners, the attributes and performance of building materials and components are being scrutinized more closely. In order to maximize levels of efficiency by examining the details of how each individual component of a house performs on its own and as part of a dynamic system, very specific properties are measured and taken into account. This can be especially helpful when trying to select the best building materials for a given application. R-value is the measurement used when quantifying a specific material’s level of thermal resistance, which is the inverse of U-value, which measures thermal conductance. R-value is often the standard consideration when discussing the effectiveness of insulation. Inspectors may want to be familiar with the specifics of R-value ratings, especially when inspecting insulation and if they also perform energy audits. How Does R-Value Relate to Insulation? Heating and cooling costs account for 50% to 70% of energy used in an average U.S. home. Inadequate insulation can account for a lot of wasted energy, so it is important to be sure that insulation installed is doing its job properly. The function of insulation is to provide resistance to the flow of heat, and R-value is ... more
