Match each statement with item below -A foundation without wall vents that encloses an intentionally heated or cooled space.

Foundations are susceptible to moisture wicking into the building through capillary action from footings and foundation walls or through slabs.

____ is a lightweight, air-entrained block that uses less energy to produce and is more energy-efficient than standard CMUs.
