When laying a radiant barrier over the insulation on the attic floor, it is possible for dust to accumulate on the top side. Many factors like dust particle size, dust composition and the amount of ventilation in the attic affect how dust accumulates and thus the ultimate performance of a radiant barrier in an attic.
Funding is available for all kinds of other upgrades as well, such as doors, windows and insulation. More information is available at energysaver.gov . Editor's note: A version of this story was ...

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.
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]
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.
A heating degree day is a unit that measures how often outdoor daily dry-bulb temperatures fall below an assumed base, normally 18 °C (65 °F). [4] For building in most parts of North America, where winter heating conditions predominate, vapor barrier are placed toward the interior, heated side of insulation in the assembly.
For insulation purposes, metal ducts are typically lined with faced fiberglass blankets (duct liner) or wrapped externally with fiberglass blankets (duct wrap). When necessary, a double walled duct is used. This will usually have an inner perforated liner, then a 1–2" (2.5-5 cm) layer of fiberglass insulation contained inside an outer solid pipe.
