A house should be well insulated,
using materials that provide good coverage within wall cavities,
attics and at the foundation. Insulation also can help to eliminate
interior condensation problems within the walls by keeping cool
air and warm air from meeting in the wall and condensing into
water vapor that can contribute to mold growth. Insulation used
within the home's interior walls can provide good acoustical control
and may be exceptionally helpful for reducing sound between different
areas of the home.
