AND WHY IT'S IMPORTANTEXPLAINING WHAT "R-VALUE" MEANS
THE R-VALUE OF INSULATION IS VERY IMPORTANTWHEN YOU ARE TRYING TO CHOOSE THE BEST KIND.
R-value measures thermal resistanceor the ability to prevent the transfer of heat.
The larger the R-value number,the more effective the insulation isat preventing heat conduction.
The less heat loss there is with a particular type of insulation,the less you will pay for your energy bills each month.
The standard R-value for roofs is R-30 or R-40.
R-value directly related to the transfer of heatthrough a material (walls in a home)
Most homes have holes on the outside that heat can pass through,requiring air conditioning to be run,thereby increasing energy bills for a home.
The most common types of insulation available todayare fiberglass and foam board.
Spray foam insulation has a very high R-valuebecause it is so effective at preventing heat transfer.
Insulation that is used for walls in a home should be R-19,whereas insulation used for roofing should be R-30 or R-40.
A high R-value is absolutely required for establishingan effective thermal barrier to prevent conduction in a home.
High R-value insulations can save householdshundreds of dollars on energy bills over just a year.
