Basement walls made out of concrete stone concrete bloc and other masonry foundation materials have very minimal insulating properties and cause approximately 20 of heat loss in a home.

In these walls continuous exterior insulation envelopes the masonry minimizing the effect of thermal bridges. As long as at least half the continuous insulation is on the exterior r15 is fine. As the federal energy star program and international energy conservation code continue to push the envelope for effectively insulating exterior walls against thermal loss to boost a home s energy efficiency builders of block walls are being forced to adjust their practices to comply with the more stringent standards.
