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]
Types of External cromatic wall insulation systems (EWI Systems pictured above) 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).
The borates in cellulose insulation provide added control against mold. Installations have shown that even several months of water saturation and improper installation did not result in mold. [10] It is a common misconception that the mere presence of crude borates in cellulose insulation provides pest control properties to the product.
This is a list of insulation materials used around the world. Typical R-values are given for various materials and structures as approximations based on the average of available figures and are sorted by lowest value.
One example is AirKrete, [5] at R-3.9 (RSI-0.69) per inch and no restriction on depth of application. Non-hazardous. Non-hazardous. Being fireproof, it will not smoke at all upon direct contact with flame, and is a two-hour firewall at a 3.5 in (89 mm) (or normal 2 in × 4 in (51 mm × 102 mm) stud wall) application, per ASTM E-814 testing (UL ...
