In both residential and commercial construction, continuous insulation (ci) – wrapping the exterior wall in a continuous layer of rigid foam insulation around the studs and the cavity – offers one of the best ways to block thermal bridging. It also results in walls with a higher R-value than using batt insulation alone. The benefits of continuous insulation include a reduction in heat loss, prevention of mold and mildew accumulation in the wall and better protection against water intrusion.
