This summarizes an uninsulated basement even though the code requirements in DOE climate zones 4 and higher do not allow an uninsulated basement in new construction where the basement is conditioned… Read More

This is another alternative to the minimum code required basement insulation in DOE climate zones 4 and higher. This construction uses a 2x4 framed wall against the concrete foundation with R-13… Read More

This construction uses insulated concrete form (ICF) with 2" XPS rigid insulation on the interior and exterior of the concrete foundation wall. The slab is insulated with 2" XPS rigid insulation… Read More

This construction uses continuous R-10 or R-13 batt insulation on the interior of the concrete foundation wall. The slab is left uninsulated and the rim joist is insulated with batt insulation. … Read More

This construction uses 2x4 framed wall offset 2.5" from concrete with 6" open cell low density spray foam (R-21) between and behind the stud wall. The slab is insulated with 2" XPS rigid insulation… Read More

The figure below shows 2" XPS or foil-faced polyisocyanurate rigid insulation and 6" open cell low density spray foam insulation installed on the interior of the rimjoist and foundation wall, and 2"… Read More
