Attic with no insulation
Enter 1.7
Walls with no insulation
Enter 4.7

* R-Values and their metric equivalent, RSI values, are a way of labeling the effectiveness of insulating materials. The higher the R-value or RSI value, the more resistance the material has to the movement of heat. Insulation products sold in Canada are labeled with R and RSI values.
