Understanding Insulation R-Value
In construction, the R-values for home insulation is a way to measure how well a barrier resists the conductive flow of heat. A real-life example of conduction you might be familiar with is how your spoon heats up after being placed in hot coffee.
Insulation works by slowing your conductive heat flow. To enjoy the perfect temperature in your home, your heating system has to replace lost heat in your home in the winter and remove it in summer. Effective insulation will decrease heat flow and provide resistance to it.
To determine its effectiveness, insulation is graded using varying levels of the R-value. The R-value is rated in terms of thermal resistance. Depending on the type of thickness and density of your insulation, its R-value may go up or down.
Installing more attic insulation will increase your R-values and improve efficiency in your home. Depending on where you live, you may need more insulation than you have currently. The type of home you have, too, affects the level of insulation required. Check in with a professional to get the right R-value for your home.
