The R-value of a material is a measure of its ability to resist heat flow. The higher the R-value, the greater the resistance to heat flow. For exterior walls, a higher R-value means that less heat will be transferred through the wall, resulting in a more energy-efficient building. The R-value of a wall is determined […]

An R-value, or thermal resistance, is a measure of how well a material resists the flow of heat. It is expressed in units of ftFh/Btu. A higher R-value indicates a greater resistance to heat flow and, therefore, a better insulator. When considering exterior walls, selecting proper insulation is essential for maintaining comfortable indoor temperatures, reducing […]
