R-Value - Insulation - Oak Ridge National Laboratory
Rigid insulation is made from fibrous materials or plastic foams and is produced in board-like forms and molded pipe coverings. These provide full coverage with few heat loss paths and are often able to provide a greater R-value where space is limited.
R-Value - Insulation - Oak Ridge National Laboratory
R-Value Introduction. Why Insulate Your House? Heating and cooling account for 50 to 70% of the energy used in the average American home. Inadequate insulation and air leakage are leading causes of energy waste in most homes.
Radiant - Oak Ridge National Laboratory
What is a radiant barrier? Radiant barriers are materials that are installed in buildings to reduce summer heat gain and winter heat loss, and hence to reduce building heating and cooling energy usage. The potential benefit of attic radiant barriers is primarily in …
