CompareR-valuesfor allinsulationtypes with our completechart. Fiberglass, spray foam, mineral wool, rigid foam & more — with costs, thickness, and recommendations.
Insulationlevels are specified byR-Value.R-Valueis a measure ofinsulation'sability to resist heat traveling through it. The higher theR-Valuethe better the thermal performance of theinsulation. The table below shows what levels ofinsulationare cost-effective for different climates and locations in the home.

ThisR-valuetable gives standardR-valuesfor 49 building materials, includinginsulationand roofing products. CalculateR-valuesusing thischart.
What areR-values? In construction, theR-valueis the measurement of a material's capacity to resist heat flow from one side to the other. In simple terms,R-valuesmeasure the effectiveness ofinsulationand a higher number represents more effectiveinsulation.R-valuesare additive. For instance if you have a material with anR-valueof 12 attached to another material with anR-valueof 3 ...

The range ofR-valuesofinsulationmaterials spans from materials with R-10insulationvaluesper inch like vacuum insulated panels and silica aerosol to below R-1valuesper inch like bricks, glass, and poured concrete.
