R-Value
R-Value is a simple way to measure how well insulation materials stop heat from passing through them. Think of it like a grade for insulation effectiveness - the higher the R-Value, the better the material is at keeping heat where it belongs. In roofing jobs, this term comes up often because proper insulation helps buildings stay warm in winter and cool in summer, leading to better energy efficiency. When you see this on a resume, it shows the person understands the importance of energy efficiency in construction and knows how to work with different insulation materials.
