Glass wool batt insulation. Glass wool is an insulating material made from glass fiber arranged using a binder into a texture similar to wool.The process traps many small pockets of air between the glass, and these small air pockets result in high thermal insulation properties.

While in 1976 there were roughly 100 cellulose insulation firms with 125 plants in the US, by 1978 there were more than 350 firms with more than 500 plants 1. Cellulose insulation was produced locally by small manufacturers who purchased ready-to-operate machines and offered a cheap and easy low-tech production process.
Materials have a moisture vapor transmission rate (MVTR) that is established by standard test methods. One common set of units is g/m 2 ·day or g/100in 2 ·day. Permeability can be reported in perms , a measure of the rate of transfer of water vapor through a material (1.0 US perm = 1.0 grain/square-foot·hour· inch of mercury ≈ 57 SI perm ...
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 ...
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).
