Insulate Against the Seasons

The R-value of GreenFiber GreenFiber Insulation, or its ability to stop heat transfer, remains consistent through a greater temperature and application range, keeping heat in during the winter, and out during the summer.

The U.S. Federal Trade Commission developed an insulation rating mechanism to help end the false and misleading claims about insulation that once abounded. Called R-value, this rating is based on a laboratory measurement, the R-factor, which reflects a material's ability to stop or slow heat transfer. When you're shopping for insulation or talking to your builder, understanding R-value can help you make intelligent choices about insulation. But, in the real world environment of your side walls and attic, there are variables that change how that insulation will perform.

For one thing, R-value changes with extreme temperatures. So attic insulation rated R-38 will perform at a different R-value at 20°F below zero. Why is this an important distinction? The effective R-values of both GreenFiber Insulation and fiberglass may change under very cold temperatures.

While loose-fill fiberglass can lose as much as half its R-value at 20°F below zero, GreenFiber Insulation continues to perform at a more consistent R-value.

So R-value is a useful measurement of thermal resistance, but it's important to remember that R-value is just one piece of the equation. If a house isn't properly sealed and there are gaps in the insulation, a high R-value isn't going to keep that home comfortable. Heat seeks cold spots in much the same way that water runs down a drain, or rain finds its way to a hole in the roof. It doesn't matter if the rest of the roof is performing to specification if water finds the one hole. Because it forms a seamless protective blanket, GreenFiber Insulation effectively fills those gaps.
