Insulation will help you keep the desired temperature in your house all year round, protecting it against cold in winter and excess heat in summer. Insulation is also useful to reduce noise pollution. A well sealed and insulated home will be more comfortable, and create less work for the heating and cooling systems. Homeowners and building owners need to find out the recommended insulation thermal resistance level, or R-Value, their region and work to at least match that level. If an area of the home or building’s insulation doesn’t meet or exceed the DOE’s recommended R-Value, more insulation should be installed to raise the R-Value to the desired level.
