Key Differences
R-values of SIPs
The R-value (thermal resistance) of a building material measures its ability to resist heat flow, with higher values indicating better insulation. When comparing Structural Insulated Panels (SIPs) to stud frame construction, the differences in R-value are significant.
Structural Insulated Panels (SIPs) generally offer higher whole-wall R-values and better energy efficiency than stick-framed construction due to their continuous insulation and reduced thermal bridging, while stick-framed homes can experience a significant reduction in insulation performance due to thermal bridging.

Continuous Insulation: SIPs provide a continuous layer of insulation across the entire wall without gaps or thermal bridges. In contrast, stick frame walls have studs spaced apart, creating gaps that reduce their overall insulation performance.
Higher R-value: SIPs generally have a much higher R-value than stud frame walls, offering superior thermal resistance and better energy efficiency.
