R-20 insulation is a type of fiberglass batt insulation designed to provide higher thermal resistance for walls and other building assemblies. The R-value (R-20) indicates the insulation’s ability to resist heat flow, helping maintain comfortable indoor temperatures and improve overall energy efficiency.
What R-20 Means
The R-value measures how effectively insulation slows the transfer of heat.
-
R-20 offers stronger thermal performance compared to lower R-values like R-12 or R-14.
-
It helps keep buildings warmer during winter and cooler during summer.
-
Higher R-values contribute to lower heating and cooling costs.
Material
R-20 insulation is typically made from fiberglass fibers that trap pockets of air, creating an effective thermal barrier. Fiberglass insulation is widely used in residential and commercial construction because it is lightweight, durable, and easy to install.
