The primary functions of a fireback are to protect the wall at the back of the fireplace and radiate heat from the fire into the room. The protection was especially important where the wall was constructed of insubstantial material such as daub (a mud and straw mixture coating interwoven wooden wattles), brick or soft stone.
The effective insulating value depends on the number of adjacent dead air spaces, layers of foil and where they are installed. If the foil is laminated to rigid foam insulation, the total insulating value is obtained by adding the RSI of the foam insulation to the RSI of the dead air space and the foil.
Insulation is a barrier material to resist/reduce substance (water, vapor, etc. ) /energy (sound, heat, electric, etc.) to transfer from one side to another. Heat/ Thermal Insulation is a barrier material to resist / block / reflect the heat energy (either one or more of the Conduction, Convection or Radiation) to transfer from one side to another.
Thermal insulation in buildings is an important factor in achieving thermal comfort for its occupants. [4] Insulation reduces unwanted heat loss or gain and can decrease the energy demands of heating and cooling systems. It does not necessarily deal with issues of adequate ventilation and may or may not affect the level of sound insulation.
A Zero-Energy Building (ZEB), also known as a Net Zero-Energy (NZE) building, is a building with net zero energy consumption, meaning the total amount of energy used by the building on an annual basis is equal to the amount of renewable energy created on the site [1] [2] or in other definitions by renewable energy sources offsite, using technology such as heat pumps, high efficiency windows ...
Thermal insulation is the reduction of heat transfer (i.e., the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radiative influence. [1] Thermal insulation can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials.
Modern open fireplace An outdoor fireplace. A fireplace or hearth is a structure made of brick, stone or metal designed to contain a fire. Fireplaces are used for the relaxing ambiance they create and for heating a room. Modern fireplaces vary in heat efficiency, depending on the design.
The first expanded polystyrene ICF Wall forms were developed in the late 1960s with the expiration of the original patent and the advent of modern foam plastics by BASF. [citation needed] Canadian contractor Werner Gregori filed the first patent for a foam concrete form in 1966 with a block "measuring 16 inches high by 48 inches long with a tongue-and-groove interlock, metal ties, and a waffle ...
