The r value is a measure of an insulation sample s ability to reduce the rate of heat flow under specified test conditions.

Insulation r value. You could think of r value as the resistance value. The r value is in essence the measurement of an insulation sheet s ability to resist heat flow. The r value of a material is its resistance to heat flow through the material.

Basically r values range from 1 5 to 7 and the higher the number is the more effective the insulation sheet is at increasing thermal efficiency and thereby insulating your home. In general higher r means more resistance to heat loss and therefore lower heating or cooling bills for the building. R value figure is usualy provided by the manufacturer of a particular insulation product and is shown in the product description.

If it resists the flow of heat well has a high r value then it s a good insulating material. An r value is in short a number that tells you how good a material is at resisting the flow of heat. The primary mode of heat transfer impeded by insulation is conduction but insulation also reduces heat loss by all three heat transfer modes.

R value thickness m thermal conductivity w mk unlike thermal conductivity thermal resistance r values solely depend on the material s thickness. R value figure can be calculated from the equation. Currently the recommended r value for attic insulation is between 6 1 and 7 a combination of thickness and conductivity.

When buying various insulation materials you will almost always see an r value quoted for the material. An r value is a term of measurement relating to the amount of resistance that a material has to conductive heat flow. Conduction convection and radiation.

R values and heat loss. Knowing where you stand with the recommended r value for attic insulation will ensure that you receive the right insulation for your home.
