An important thing to remember when purchasing insulation or when making a choice is that you want to get a product that has the best R value, and not judge insulation by its weight or thickness. The R value is the amount of thermal resistant that the insulation provides, so the better the R value [...]
R-values measure the thermal resistance of a material, and the measure is important when determining the effectiveness of the insulation of a building. Materials with higher R-values are better insulators. Materials can be compared by referring to an insulation R value chart. Be aware when referring to data that most countries use SI (metric) units [...]
R value is the measure of the resistance of a material to heat transfer. Specifically, the R value measures the time for heat to transfer from one side of a material to the other side. You can think of R value as a way to calculate the number of hours a square foot surface of [...]
R value is an important part of all the insulation materials. The R value is usually expressed in terms of the thickness of the materials. Each insulation material has it advantages and disadvantages and is best used in certain areas of the house. For example, the foam insulation is generally used to fill tight spaces [...]
