What are Insulation R-Values?
Insulation R-values are numerical values that indicate the level of thermal resistance in insulation. Thermal resistance is the ability of a material to reduce the heat loss of a wall. In the building and construction industry, the insulation R-value is a measure of the effectiveness of insulation products. The insulation R-value of a material is determined under very specific test conditions, designed to mimic the standard home. Insulation is used to stop the loss of heat through convection, conduction and radiation. In homes and buildings, most of the air in a room is lost through natural convection to the outside.

Insulation is used to stop the loss of heat through convection, conduction and radiation. In homes and buildings, most of the air in a room is lost through natural convection to the outside. Insulation works as a barrier to heat loss by acting just like trapped air. The insulation fills up the space between the outer wall and the inner walls of a room. The higher the insulation R-value, the closer it is to the thermal conductivity of trapped air. Air cannot move through air, and so the insulation eliminates heat loss through natural convection by forming an in
