R-value

R-value measures a material’s ability to resist heat flow. Higher R-values indicate better insulation, meaning the material effectively slows the transfer of heat between two areas. This helps keep indoor spaces warm in winter and cool in summer, improving energy efficiency. R-value is determined by the thickness and type of insulation material; thicker and denser materials generally have higher R-values. It’s a key factor when selecting insulation for buildings, ensuring comfort and reducing energy costs.
