Exterior insulation and finish system (EIFS) is a general class of non-load bearing building cladding systems that provides exterior walls with an insulated, water-resistant, finished surface in an integrated composite material system. EIFS has been in use since the 1960s in North America and was first used on masonry buildings.
The thermal insulation requirements in the USA follow the ASHRAE 90.1 which is the U.S. energy standard for all commercial and some residential buildings. [13] ASHRAE 90.1 standard considers multiple perspectives such as prescriptive, building envelope types and energy cost budget.
Installed faced fiberglass batt insulation with its R-value visible (R-21) [1]. The R-value is a measure of how well a two-dimensional barrier, such as a layer of insulation, a window or a complete wall or ceiling, resists the conductive [2] flow of heat, in the context of construction. [3]
External wall insulation systems generally comprise firstly an insulation layer (an element which helps to achieve the requisite thermal performance); and secondly,a protected weatherproof finish (usually a render, although brick slips, [3] tiles, and decorative boards can also be used). Insulating render can also be an advantage in certain ...
Radiant barrier may be used as a vented skin around the exterior of a wall. [10] Furring strips are applied to the sheathing to create a vented air space between the radiant barrier and the siding, and vents are used at the top and bottom to allow convective heat to rise naturally to the attic.
Therefore, thermal insulation profiles are used to create a thermal separation of the inner and outer shells of metal frames. The variety of thermal insulation profiles (Insulbar) allows low U f values (for example 1.3 W/m 2 K by using a 34mm insulation profile and up to 1.1 W/m 2 K with contemporary aluminum systems) to be reached.
