Insulation Comparison Fiberglass Fiberglass insulation is made of silica sand and recycled glass, both abundant resources. Producing fiberglass insulation requires melting the materials in a fossil fuel–burning furnace, which consumes substantial amounts of energy and generates greater amounts of air pollution than the manufacture of other insulation types. If installed properly, there is little danger Read more...
In order to retard heat flow by conduction, walls and roofs are built with internal air spaces. Conduction and convection through these air spaces combined represent only 20% to 35% of the heat which pass through them. In both winter and summer 65% to 80% of the heat that passes from a warm wall to Read more...
Reflective insulation and radiant barriers reduce the radiation of heat to or from the surface of a material. Radiant barriers will reflect radiant energy. A radiant barrier by itself will not affect heat conducted through the material by direct contact or heat transferred by moist air rising or covection. For this reason, trying to associate Read more...

There are three modes of heat transfer: CONDUCTION, CONVECTION, and RADIATION (INFRARED). Of the three, radiation is the primary mode; conduction and convection are secondary and come into play only as matter interrupts or interferes with radiant heat transfer. As matter absorbs radiant energy, it is heated and a gradient temperature develops, which results in Read more...
